The success of an oral presentation lies in the speaker’s ability to transmit information to the audience. Lucia Hartigan and colleagues describe what they have learnt about delivering an effective scientific oral presentation from their own experiences, and their mistakes

The objective of an oral presentation is to portray large amounts of often complex information in a clear, bite sized fashion. Although some of the success lies in the content, the rest lies in the speaker’s skills in transmitting the information to the audience. 1

Preparation

It is important to be as well prepared as possible. Look at the venue in person, and find out the time allowed for your presentation and for questions, and the size of the audience and their backgrounds, which will allow the presentation to be pitched at the appropriate level.

See what the ambience and temperature are like and check that the format of your presentation is compatible with the available computer. This is particularly important when embedding videos. Before you begin, look at the video on stand-by and make sure the lights are dimmed and the speakers are functioning.

For visual aids, Microsoft PowerPoint or Apple Mac Keynote programmes are usual, although Prezi is increasing in popularity. Save the presentation on a USB stick, with email or cloud storage backup to avoid last minute disasters.

When preparing the presentation, start with an opening slide containing the title of the study, your name, and the date. Begin by addressing and thanking the audience and the organisation that has invited you to speak. Typically, the format includes background, study aims, methodology, results, strengths and weaknesses of the study, and conclusions.

If the study takes a lecturing format, consider including “any questions?” on a slide before you conclude, which will allow the audience to remember the take home messages. Ideally, the audience should remember three of the main points from the presentation. 2

Have a maximum of four short points per slide. If you can display something as a diagram, video, or a graph, use this instead of text and talk around it.

Animation is available in both Microsoft PowerPoint and the Apple Mac Keynote programme, and its use in presentations has been demonstrated to assist in the retention and recall of facts. 3 Do not overuse it, though, as it could make you appear unprofessional. If you show a video or diagram don’t just sit back—use a laser pointer to explain what is happening.

Rehearse your presentation in front of at least one person. Request feedback and amend accordingly. If possible, practise in the venue itself so things will not be unfamiliar on the day. If you appear comfortable, the audience will feel comfortable. Ask colleagues and seniors what questions they would ask and prepare responses to these questions.

It is important to dress appropriately, stand up straight, and project your voice towards the back of the room. Practise using a microphone, or any other presentation aids, in advance. If you don’t have your own presenting style, think of the style of inspirational scientific speakers you have seen and imitate it.

Try to present slides at the rate of around one slide a minute. If you talk too much, you will lose your audience’s attention. The slides or videos should be an adjunct to your presentation, so do not hide behind them, and be proud of the work you are presenting. You should avoid reading the wording on the slides, but instead talk around the content on them.

Maintain eye contact with the audience and remember to smile and pause after each comment, giving your nerves time to settle. Speak slowly and concisely, highlighting key points.

Do not assume that the audience is completely familiar with the topic you are passionate about, but don’t patronise them either. Use every presentation as an opportunity to teach, even your seniors. The information you are presenting may be new to them, but it is always important to know your audience’s background. You can then ensure you do not patronise world experts.

To maintain the audience’s attention, vary the tone and inflection of your voice. If appropriate, use humour, though you should run any comments or jokes past others beforehand and make sure they are culturally appropriate. Check every now and again that the audience is following and offer them the opportunity to ask questions.

Finishing up is the most important part, as this is when you send your take home message with the audience. Slow down, even though time is important at this stage. Conclude with the three key points from the study and leave the slide up for a further few seconds. Do not ramble on. Give the audience a chance to digest the presentation. Conclude by acknowledging those who assisted you in the study, and thank the audience and organisation. If you are presenting in North America, it is usual practice to conclude with an image of the team. If you wish to show references, insert a text box on the appropriate slide with the primary author, year, and paper, although this is not always required.

Answering questions can often feel like the most daunting part, but don’t look upon this as negative. Assume that the audience has listened and is interested in your research. Listen carefully, and if you are unsure about what someone is saying, ask for the question to be rephrased. Thank the audience member for asking the question and keep responses brief and concise. If you are unsure of the answer you can say that the questioner has raised an interesting point that you will have to investigate further. Have someone in the audience who will write down the questions for you, and remember that this is effectively free peer review.

Be proud of your achievements and try to do justice to the work that you and the rest of your group have done. You deserve to be up on that stage, so show off what you have achieved.

Oral presentation

Giving an oral presentation as part of a speaking exam can be quite scary, but we're here to help you. Watch two students giving presentations and then read the tips carefully. Which tips do they follow? Which ones don’t they follow?

Instructions

Watch the video of two students doing an oral presentation as part of a speaking exam. Then read the tips below.

Melissa: Hi, everyone! Today I would like to talk about how to become the most popular teen in school.

Firstly, I think getting good academic results is the first factor to make you become popular since, having a good academic result, your teacher will award you in front of your schoolmates. Then, your schoolmates will know who you are and maybe they would like to get to know you because they want to learn something good from you.

Secondly, I think participating in school clubs and student unions can help to make you become popular, since after participating in these school clubs or student union, people will know who you are and it can help you to make friends all around the school, no matter senior forms or junior forms.

In conclusion, I think to become the most popular teen in school we need to have good academic results and also participate in school clubs and student union. Thank you!

Kelvin: Good evening, everyone! So, today I want to talk about whether the sale of cigarettes should be made illegal.

As we all know, cigarettes are not good for our health, not only oneself but also other people around. Moreover, many people die of lung cancer every year because of smoking cigarettes.

But, should the government make it illegal? I don’t think so, because Hong Kong is a place where people can enjoy lots of freedom and if the government banned the sale of cigarettes, many people would disagree with this and stand up to fight for their freedom.

Moreover, Hong Kong is a free market. If there's such a huge government intervention, I think it’s not good for Hong Kong’s economy.

So, if the government wants people to stop smoking cigarettes, what should it do? I think the government can use other administrative ways to do so, for example education and increasing the tax on cigarettes. Also, the government can ban the smokers smoking in public areas. So, this is the end of my presentation. Thank you.

It’s not easy to give a good oral presentation but these tips will help you. Here are our top tips for oral presentations.

• Use the planning time to prepare what you’re going to say. 
• If you are allowed to have a note card, write short notes in point form.
• Use more formal language.
• Use short, simple sentences to express your ideas clearly.
• Pause from time to time and don’t speak too quickly. This allows the listener to understand your ideas. Include a short pause after each idea.
• Speak clearly and at the right volume.
• Have your notes ready in case you forget anything.
• Practise your presentation. If possible record yourself and listen to your presentation. If you can’t record yourself, ask a friend to listen to you. Does your friend understand you?
• Make your opinions very clear. Use expressions to give your opinion .
• Look at the people who are listening to you.
• Write out the whole presentation and learn every word by heart. 
• Write out the whole presentation and read it aloud.
• Use very informal language.
• Only look at your note card. It’s important to look up at your listeners when you are speaking.

Useful language for presentations

Explain what your presentation is about at the beginning:

I’m going to talk about ... I’d like to talk about ... The main focus of this presentation is ...

Use these expressions to order your ideas:

First of all, ... Firstly, ... Then, ... Secondly, ... Next, ... Finally, ... Lastly, ... To sum up, ... In conclusion, ...

Use these expressions to add more ideas from the same point of view:

In addition, ... What’s more, ... Also, ... Added to this, ...

To introduce the opposite point of view you can use these words and expressions:

However, ... On the other hand, ... Then again, ...

Example presentation topics

• Violent computer games should be banned.
• The sale of cigarettes should be made illegal.
• Homework should be limited to just two nights a week.
• Should school students be required to wear a school uniform?
• How to become the most popular teen in school.
• Dogs should be banned from cities.

Check your language: ordering - parts of a presentation

Check your understanding: grouping - useful phrases, worksheets and downloads.

Do you think these tips will help you in your next speaking exam? Remember to tell us how well you do in future speaking exams!

How to Do an Oral Presentation

Last Updated: March 29, 2024

The power of words can control the thoughts, emotions and the decisions of others. Giving an oral presentation can be a challenge, but with the right plan and delivery, you can move an entire audience in your favor.

Researching Your Presentation

• If speaking about the effect of junk food on an adult’s mind, include the increase of serotonin, a happiness hormone. Then inform the audience how fast the hormone drastically depletes to give out worse feelings. This gives the perspective that even the advantages of junk food are outweighed by the negative effects.

Writing Your Script

• Make sure to begin each argument with a clear description of the content such as. "The result of eating junk food has increased negative emotions such as depression, anxiety and low self-esteem". This gives the audience a quick outlook of what the argument is about. Always remember to state how the argument relates and supports the topic question.

• If necessary, this is where you could include, "My name is ___ and I will be speaking about the effect on junk food on our minds." Then you include a brief out view of each argument you will be speaking about. Do not include any information about your arguments in the introduction.

• Some example concluding sentences include, "The entire process of the mind, changed by a simple bite of a cookie. Our entire body's control system, defined by our choices of food. The definite truth. You are what you eat."

Practicing and Performing

• Taking the effort to memorize your script allows you to keep eye contact with the audience and brings confidence to your speech. Reading from an entire script can easily cause you to lose your place and stutter. Also make sure they are the same size and only put important key words or those that are hard to remember. This allows you to easily flip through and read off the cue cards.

20 Tips For Preparing An Effective Oral Presentation

Don’t mind the informal me, I just seem to love that ‘down-to-earthness’ – I personally believe that such disposition is a better facilitator of effective communication.

Without much ado, I am going to share with you some ideas on what I can safely call most people’s nightmare (next to examinations, of course) – An oral presentation.

Organizations and other platforms have also come to discover the essence of an effective oral presentation. How it can move an employee from a zero state of mind to an excited state of mind after a brief but powerful presentation.

Businesses are not left out too as it has become a core value that has to be portrayed to convince potential clients about a business idea.

Read this: How to manage your time effectively

Essentially, oral presentations are nothing to be scared of.

They add some kind of depth to the learning experience.

Not having this depth is what we should be scared of. Self-expression is just one of the core pillars of assessing how much and how well a student or presenter has assimilated the content of instructional material.

Overall, some of the most faced challenges associated with oral presentations are content and stage management which shall be discussed broadly here.

Whether you are a student, employee, professional or businessman , you sure need this skill to make a good impression.

Enjoy these tips, internalize them and start putting them into good practice. At the end of this write-up, you will discover the peculiar challenges of stage fright, how to deal with it and a few tidbits on presentation etiquette.

1. Know the content

Nothing breeds confidence like competence and nothing breeds competence like preparation . Being vast in and thoroughly familiar with whatever the subject of a presentation will, in no small way, reinforce your sense of having something genuinely interesting to offer.

With this in place, the presentation ceases to be a mere talk or some kind of recital. It indeed becomes an active engagement of the audience on a journey of discovery. All you need do is just visualize yourself as a tour guide or a curator in a museum.

All you need do is to relate antecedents, history, origins, facts, figures and aspects of the subject matter in such a way as to stimulate their imagination.

You lead the audience on, not exactly projecting yourself but helping them see what needs to be seen. You wouldn’t want to go to the stage and destroy the expectations of people eagerly waiting to listen to you.

2. Define the purpose of the presentation

A presentation isn’t just a list of random facts. It makes a specific point, just like laboratory reports or essays.

Without a clear purpose in mind, your presentation will most likely be a jumble of unorganized factual information, putting your audience in the dark about your true intent.

What is the most important message you want to convey to the audience? Consider this to be the idea or theme of your presentation.

Your presentation’s goal(s) could include, but are not restricted to, trying to inform, inspire, or persuade.

Remember that what you say as well as how you say it must be consistent with the presentation’s goal.

3. Be natural

The mistake a lot of presenters make is thinking that great presentations are all about big vocabulary and sophisticated terms.  

May I indulge you in a different perspective – great presentations are all about presentations done in the most natural way. Be calm, relax and flow effortlessly .

Do your presentations like they are your daily routines. Help your audience feel like – “yes, I agree with what he is talking about”.

Rather than trying to charm the audience with a sophisticated style, be more committed to capturing their imagination through simple cues and vivid expressions.

There is a child in everyone, no matter how old. If possible, add a little humour here and there but try not to overdo it. Ensure you stay on track.

4. Invoke curiosity

This aspect is what makes your audience hooked until the end of your presentation. They want to know where you are headed. They can’t risk being distracted until you finish. All you need do is reawaken that curious infant in the brief moment of your presentation.

It is for this reason that presentations adopt visual aids and graphical tools. The world-famous PowerPoint computer application also goes hand in hand with projectors – large screens for a clearer, broader view.

Where else is such pervasive attention given to pictures and descriptive tools apart from a kindergarten? Such applications show that there is a childlike nature in every man. Invoke it!

5. Get your audience involved

Get your audience involved in your presentation. Don’t stand behind a lectern all through, tale a brisk, confident walk and project your words into the minds of your audience. Don’t let the lectern come in between you and the audience.

Try to get your audience out of their seats, laughing, raising hands or even standing by your side to make an analysis. Getting your audience to laugh is not as difficult as you might think. For example, you might try, “Ladies and gentlemen, I was told to announce something very critical to the success of today’s event. Even though I don’t think it’s my place to begin my presentation with an announcement that has nothing to do with my topic.”

“Anyway, I’ve been asked to tell you that in the event that you laugh too hard, don’t cause a stampede or fart too loud.” 😆

6.  Gesticulate

If you can request a cordless lavaliere mic, pls do, so that you can be as flexible with your hands as possible. A handheld mic might become tiring if your presentation takes a while.

Your audience will only remember 30% of what they hear & see but 70% of what they do will stick to them forever.

7. Project your words

Two things that can make your projection so vivid and impactful are a clear voice and clarity of communication. Try to emphasize the last sound of each word which will help you to sound very polished. This may sound odd to you when you start but eventually sound normal as you get used to it.

8. Take a pause

I cannot stress this enough. Take your time to pause! It kinda helps your audience to brainstorm, evaluate and re-evaluate. You shouldn’t say more than six to eight words at a time without a pause. As longer sentences reduce readability, longer spoken words also reduce absorption.

Use a full voice, then pause. Think of great speakers that utilized a full voice and paused. They did efficiently well. Such presentations drop some value within you.

9. Use acronyms

After you have written all the words on index cards, try to think of an acronym or Slang abbreviation that has every point you want to talk about. Use this strategy to keep your presentation in order.

For example, you may have written on a marriage/relationship index card – ask, support, kiss . Think of the first letter in each word and arrange them to ASK or any other word of your choice.

ASK will keep you on track this way:

A – Ask what he thinks

S – Support his opinion first

K – Kiss him when the discussion ends

You must have practised what you will say about each word beforehand. You will only use the acronym to keep track which the audience has no clue about. They will only think you are so perfect! If your oral presentation takes time and involves longer acronyms, you could keep your index card(s) on you just in case you get lost. 

10. Give life to figures

The best way to do this is to put a ‘Point’ of mind-gripping information (pictures, graphs, a phrase or table, flow charts, diagrams or a statistic) on some slides and speaking to them.

While the audience is fixated on that slide, all you need do is try to make them see the aspects of the slides that are hidden. Hence, you help to make their imagination make up for the rest of the story.

Such information is alike in features such as introduction, plot build-up, themes climax/anticlimax, a hero and his trials/triumph and so on.

And like a good storyteller or the mythical Pied Piper, the story or the music as the case is, becomes the object of the audience’s attention. The presenter is merely an intermediary.

11. Face the object

Sure, it is not bad to feel weird for a moment. Gain your confidence back by becoming the audience for a moment.

Face the presentation with your hands towards the slide, board or what have you? Making this brief move takes a whole lot of burden off as you see that you do not have to be the audience’s object of attention for a while.

You can use this moment to stealthily move from your weak points to your strong points as you gain your confidence back .

Not all presentations have to be a serious one looking like a board meeting. It doesn’t have to be a brainstorming session to close a million-dollar deal. Smile if you can.

In fact, you should smile. It will reduce any pressure you might be feeling. You never know how powerful a smile can be until you smile at a confused child who looks at you and then returns the smile.

While you smile, make good eye contact with them and gesticulate as often as possible. This will create a good impression on your audience and make them connect with you easily.

13. Intrigue them with stories

Whether it’s a story your grandfather told you or a story you learnt while growing up, people would love to listen. Stories are interesting ways to give your audience a light mood.

Who doesn’t like the taste of a little icing on the cake or peanuts in the chocolate? Just something a little bit different to ease the whole seriousness of the atmosphere.

Professional speakers are becoming professional storytellers ,  primarily stories about themselves or someone they know so well . If you can tell a story about each word or topic on your cards or slides, your speech will have a better flow.

14. Take corrections politely

One mistake people do is to try to show that they know better than their judges.

Judges, examiners, instructors or even a member of your audience can come into your presentation abruptly. Prepare your mind ahead for this and don’t fidget.

A simple “Noted, sir” “sorry, I skipped that” or “thanks for the feedback” would go a long way in determining your final presentation score.

Be courteous and mindful of harsh emotions as you face arguments or opposition. A wrong approach in dealing with this can ruin everything you have started. So be cool with everyone.

As a matter of fact, who you are and who the audience perceives you to be is a measure of the weight of your words.

Hence, it is safer to use universally acceptable codes of conduct and principles of etiquette that will put you in the good graces of the audience.

15. Define your target audience

The audience’s reaction is the only way to judge a good presentation. What do they currently know about your subject matter?

What are their perceptions about your subject matter: will they accept whatever you say, or will you have to persuade them to change their views? Do they have a good command of the English language?

An effective oral presentation requires much more than simply presenting your ideas or giving a presentation. It is all about clear communication and connecting with the audience.

Preparation is required to create that type of presentation. You must learn about your target audience to tailor your message.

If you’re talking to experts in your field, for example, you don’t have to explain all the terms you’re using but if you expect your audience to disagree with your assertions, it’s a great idea to provide additional illustrations and go into greater detail when presenting the evidence.

You can outline your presentation with your audience in mind to explain your main points and maintain a logical flow. The more you understand your target audience, the better you will be able to communicate with them.

16. P redict your audience’s thoughts and tell them

If you’re lucky enough to predict what is on their minds, you’ll get almost 100% attention from your audience. This lowers the barriers between you and them.

They’ll say “hey, he’s so clever hahaha”. Wow, you’re absolutely right! Tell them you know what they are thinking and answer a question they haven’t yet asked you.

17. Practice your presentation beforehand

You should start with yourself first. Talk to yourself, then move on to talking to a friend or small group of friends. When you build more confidence, start by speaking for free to become more professional.

You could begin by speaking to associations and clubs. Your audience may give you more networking opportunities when they enjoy your free presentations. There are business owners in your audience or people who work for businesses looking for speakers.

In fact, t here is much more to learn while you practise. By the time you become well-known, you can start charging a token or your prices can even become non-negotiable. 😉 

18. Explore every possible detail about your subject matter

To prepare an effective oral presentation, you must thoroughly understand your subject matter, which means knowing far more than you will present.

There is no such thing as too much research. The more familiar you are with your content, the more settled and confident you will feel when presenting it to a group.

Take notes as you read about your topic. Then organize your notes for your presentation. The most straightforward structure is an outline.

In most cases, a concise outline will serve as a good template for presenting your topic. The introduction, body, and summary make up a concise outline.

• Introduction

In the introductory part, you must provide a concise context for your discussion. This is where you describe the problem or issue that the presentation will solve.

You want to immediately grab people’s attention, stimulate their interest, and get them pondering about your topic. That is what creating engaging content is all about.

The bulk of your presentation. It provides specific examples to back up your main point. This is where you add important facts, statistics, and details to your discourse.

Make certain that your material is presented articulately, with each point connected to another and clear progressions.

To summarize, highlight the previous points briefly. Use keywords from your introduction to restate your argument.

Take note of transitory phrases or words like “in summary.” Appreciate the audience for their time and, if the presentation format allows, gladly accept their questions.

A clear structure helps to support a clear and focused message, and it prevents you from jumping from concept to concept, which can make it difficult for your audience to grasp your presentation.

Having this in place, the presentation is no longer just a discussion. It truly becomes an active participation of the audience on a discovery journey. All you have to do is relate the subject’s antecedents, background, facts, statistics, and features in a way that stimulates their curiosity.

19. Use visual aids to supplement your content

It is easier to deliver an oral presentation when you employ visual aids. Visual aids, such as PowerPoint slides or printed handouts, provide structure to your presentation and assist the audience in comprehending the key points.

Since the majority of information is deemed and grasped visually, you may need to resolve this in your presentation by including a few visuals.

This would help the audience follow your discourse and possibly discuss a few of your points after the presentation is finished.

A good visual aid , as obvious as it may seem, must remain visual. Visuals can be bulleted lists or outlines, diagrams or figures, or pictures that depict crucial points that would be difficult to explain orally. Visual aids should be used to supplement, not compete with, your presentation. Use them only when they are necessary or beneficial.

20. Anticipate questions and prepare thoughtful answers in advance

A key component of preparing for an effective oral presentation is anticipating questions and creating thoughtful responses beforehand.

It demonstrates that you are knowledgeable about the subject and that you gave the subject some research. It also helps establish credibility and demonstrate your knowledge.

Additionally, it might assist you in remaining composed and assured throughout the presentation, especially if you are posed with unexpected questions. A few strategies for getting ready for questions are as follows:

• Researching your topic thoroughly: This will enable you to answer any questions that may come up about your subject matter.
• Identifying key points of confusion: Think about what aspects of your presentation may be most difficult for your audience to understand and prepare answers accordingly.
• Practicing your responses: Rehearse answering potential questions so you are more comfortable and confident when answering them during the presentation.
• Being open to feedback: Encourage your audience to ask questions and be open to feedback , even if it is critical. Take the opportunity to address any misconceptions or confusion that may have arisen during your presentation.
• Be prepared for the unexpected: Sometimes, the questions you get may be totally out of the blue, be prepared to answer those as well.

In summary, your oral presentation is highly related to your motion, posture, gesture, gesticulation, eye contact, pausing effect, response to applause and so on.

The evolving nature of education has seen many lecturers and teachers adopt oral examinations as an integral part of grading students’ performance.

That is apart from lines of study such as Medicine (Viva) and Law (mock trials) that already have oral-related content as a part of their continuous assessment.

It also affords the teacher the opportunity to do more than just teach but to also be a kind of ‘coach’ that nurtures not only the content but also the delivery of knowledge . As a teacher myself, I do subscribe to this method of teaching; after all, was it not Einstein that said – If you cannot explain it simply, then you do not understand it all.

In oral presentations, especially ones that adopt projected information, the words you speak are more important than the words you display.

However, the pictures you use are just as important as the words you speak. In no place is the saying truer – a picture is worth more than a thousand words.

Therefore, being in a position where you have to present your own perspective, with your own words and in your own style goes a long way in shaping your intellectual capabilities . It also builds self-confidence in those that eventually master it.

I wish you a hitch-free and mind-blowing experience in your next oral presentation. 😉 . Which of these tips has helped you tremendously?

Share with love!

This reminds me of my speech 101 class in college. I definitely with these tips — especially the one about knowing the content. Nothing prepares you more than knowing what you are talking about.

That’s absolutely right!

I used to work for a company that offered feedback for corporate leaders on presenting and I agree with everything you say. Bringing your personality into a presentation or speech can make a huge difference but it can take practice to get comfortable enough to bring that energy.

Yes, practice does a lot to make one perfect. Thanks for your input, Sarah.

This is a very helpful post. I wish I had read this when I was still a student. I didn’t like oral presentations and this could have given me a better perspective.

Awww, You may pass on the message to young students to ensure they get it right early.

What It Takes to Give a Great Presentation

• Carmine Gallo

Five tips to set yourself apart.

Never underestimate the power of great communication. It can help you land the job of your dreams, attract investors to back your idea, or elevate your stature within your organization. But while there are plenty of good speakers in the world, you can set yourself apart out by being the person who can deliver something great over and over. Here are a few tips for business professionals who want to move from being good speakers to great ones: be concise (the fewer words, the better); never use bullet points (photos and images paired together are more memorable); don’t underestimate the power of your voice (raise and lower it for emphasis); give your audience something extra (unexpected moments will grab their attention); rehearse (the best speakers are the best because they practice — a lot).

I was sitting across the table from a Silicon Valley CEO who had pioneered a technology that touches many of our lives — the flash memory that stores data on smartphones, digital cameras, and computers. He was a frequent guest on CNBC and had been delivering business presentations for at least 20 years before we met. And yet, the CEO wanted to sharpen his public speaking skills.

Oral Presentation Structure

Finally, presentations normally include interaction in the form of questions and answers. This is a great opportunity to provide whatever additional information the audience desires. For fear of omitting something important, most speakers try to say too much in their presentations. A better approach is to be selective in the presentation itself and to allow enough time for questions and answers and, of course, to prepare well by anticipating the questions the audience might have.

As a consequence, and even more strongly than papers, presentations can usefully break the chronology typically used for reporting research. Instead of presenting everything that was done in the order in which it was done, a presentation should focus on getting a main message across in theorem-proof fashion — that is, by stating this message early and then presenting evidence to support it. Identifying this main message early in the preparation process is the key to being selective in your presentation. For example, when reporting on materials and methods, include only those details you think will help convince the audience of your main message — usually little, and sometimes nothing at all.

The opening

• The context as such is best replaced by an attention getter , which is a way to both get everyone's attention fast and link the topic with what the audience already knows (this link provides a more audience-specific form of context).
• The object of the document is here best called the preview because it outlines the body of the presentation. Still, the aim of this element is unchanged — namely, preparing the audience for the structure of the body.
• The opening of a presentation can best state the presentation's main message , just before the preview. The main message is the one sentence you want your audience to remember, if they remember only one. It is your main conclusion, perhaps stated in slightly less technical detail than at the end of your presentation.

In other words, include the following five items in your opening: attention getter , need , task , main message , and preview .

Even if you think of your presentation's body as a tree, you will still deliver the body as a sequence in time — unavoidably, one of your main points will come first, one will come second, and so on. Organize your main points and subpoints into a logical sequence, and reveal this sequence and its logic to your audience with transitions between points and between subpoints. As a rule, place your strongest arguments first and last, and place any weaker arguments between these stronger ones.

The closing

After supporting your main message with evidence in the body, wrap up your oral presentation in three steps: a review , a conclusion , and a close . First, review the main points in your body to help the audience remember them and to prepare the audience for your conclusion. Next, conclude by restating your main message (in more detail now that the audience has heard the body) and complementing it with any other interpretations of your findings. Finally, close the presentation by indicating elegantly and unambiguously to your audience that these are your last words.

Starting and ending forcefully

Revealing your presentation's structure.

To be able to give their full attention to content, audience members need structure — in other words, they need a map of some sort (a table of contents, an object of the document, a preview), and they need to know at any time where they are on that map. A written document includes many visual clues to its structure: section headings, blank lines or indentations indicating paragraphs, and so on. In contrast, an oral presentation has few visual clues. Therefore, even when it is well structured, attendees may easily get lost because they do not see this structure. As a speaker, make sure you reveal your presentation's structure to the audience, with a preview , transitions , and a review .

The preview provides the audience with a map. As in a paper, it usefully comes at the end of the opening (not too early, that is) and outlines the body, not the entire presentation. In other words, it needs to include neither the introduction (which has already been delivered) nor the conclusion (which is obvious). In a presentation with slides, it can usefully show the structure of the body on screen. A slide alone is not enough, however: You must also verbally explain the logic of the body. In addition, the preview should be limited to the main points of the presentation; subpoints can be previewed, if needed, at the beginning of each main point.

Transitions are crucial elements for revealing a presentation's structure, yet they are often underestimated. As a speaker, you obviously know when you are moving from one main point of a presentation to another — but for attendees, these shifts are never obvious. Often, attendees are so involved with a presentation's content that they have no mental attention left to guess at its structure. Tell them where you are in the course of a presentation, while linking the points. One way to do so is to wrap up one point then announce the next by creating a need for it: "So, this is the microstructure we observe consistently in the absence of annealing. But how does it change if we anneal the sample at 450°C for an hour or more? That's my next point. Here is . . . "

Similarly, a review of the body plays an important double role. First, while a good body helps attendees understand the evidence, a review helps them remember it. Second, by recapitulating all the evidence, the review effectively prepares attendees for the conclusion. Accordingly, make time for a review: Resist the temptation to try to say too much, so that you are forced to rush — and to sacrifice the review — at the end.

Ideally, your preview, transitions, and review are well integrated into the presentation. As a counterexample, a preview that says, "First, I am going to talk about . . . , then I will say a few words about . . . and finally . . . " is self-centered and mechanical: It does not tell a story. Instead, include your audience (perhaps with a collective we ) and show the logic of your structure in view of your main message.

Sooner or later, a lot of us will be faced with the task of delivering an oral presentation. Even if this is not the first time that you are required to do so, you may still feel nervous or insecure in your ability to hold a good presentation.

Luckily, holding oral presentations is a skill like any other. It can be practiced and improved. And the more time you allocate for preparing for oral presentations, the better your presentation will be. If you want to properly prepare and improve your presentation skills , then you've come to the right place! Here's what you can do.

Preparing Your Presentation

Preparing for oral presentations begins with preparing the presentation itself. Presentations usually consist of two aspects: the oral part itself, and the presentations made in Microsoft PowerPoint that will help you to illustrate your points.

When it comes to what you will be saying during your oral presentation, you should know that, no matter how charismatic a speaker you are, taking the time to prepare is vital. As you will only have a limited time to speak, any improvisation is likely to eat up precious time. That is why you need to rehearse in advance and have a good idea of which words you will use and how you will phrase your thoughts.

Rehearsing in advance will also allow you to time your presentation. While you can rehearse in front of a mirror, it is definitely better to convince a friend or a family member to substitute for the audience. Without holding such a presentation before the actual presentation commences, there is no way to precisely time your performance. Usually, there will be parts that you will need to shorten (or you will need to speak faster during those parts), or you may find that you don't actually have enough material.

Additional tips

Preparing for oral presentations is much easier with a little help from your friends.

Here are some other tips that will help you with this part of preparing for your oral presentations:

Know your audience! For example, if you're talking to professionals in your field, there's no need to explain the terms you are using mean (and vice versa). Or, for instance, if you expect that your audience not to agree with your arguments, it's a good idea to provide more examples and to go into detail when you're presenting the evidence.

The clock is ticking, so you'll want to focus on your main points. Don't waste time on overlong introductions and detailed background information. Rather than that, get to the gist quickly and then elaborate on it.

On the other hand, some audience members might be especially interested in the details surrounding the main point. So, notify your audience that if they're interested in such details, you will be happy to answer all the questions they may have. Being prepared for dealing with questions also includes the questions to which you currently don't have an answer for. In such situations, it is best to offer to send the answer later (for example, by e-mail), once you've looked it up.

You can also prepare handouts to give out to the audience. Otherwise, the audience members may be too busy writing down notes, and incapable of fully following your presentation.

How to Make an Excellent PowerPoint Presentation

Preparing for oral presentations includes taking the time to prepare a great PowerPoint presentation. However, it is important to remember that such presentations are only there to complement the oral part of your presentation.

Under no circumstances should you read from your PowerPoint presentation during your entire performance. Rather, use it as a tool to reinforce your points in the mind of the audience, and to help you remember the structure of your oral presentation.

Use dark text against a light background if you want your audience to be able to focus.

Here are some more tips & tricks on making an excellent PowerPoint presentation:

The font should be large (avoid going under 24 points), and the typeface should be easy to read (as a rule, Sans Serif is better than Serif).

Instead of full sentences, use bullet points. Remember, you're the one who's delivering full sentences; bullet points are simply there to underline what you are saying.

When it comes to your use of colors, remember that the text should be easy to read. So, if the background is dark, the text should be light, and vice versa.

Don't use too many effects. They tend to distract the audience from what you are saying.

A website can be a good alternative to a PowerPoint presentation.

Preparing for the Delivery of Your Oral Presentations

Finally, you should also work on your delivery. When it comes to this part of your oral presentation, it is important to have the right mindset. Namely, you are not giving a speech; you are delivering a presentation! This means that you are there to actively communicate with the audience members and to try to involve them in the presentation.

And to be able to do that, the audience must be able to understand you clearly. Pay attention to see if anyone is having a hard time hearing you. If you have any written notes, you can consult them, but don't read from them all the time. Instead, maintain eye contact with the audience members. Basically, if you show an interest in your audience, if you show that you care whether they're listening to you or not, the audience will respond with interest.

The science of fear

Admittedly, this may be hard to do if you're feeling nervous. In such cases, what one suffers is called a "fight or flight reaction", something that can be explained from an evolutionary standpoint. Whenever our ancestors were scared by the dangers lurking in the primordial wilderness, their neural systems produced so-called "fear hormones", urging them to either fight or run away.

Our ancestors were rightfully afraid of lions; however, we still experience a similar fear in physically much less dangerous circumstances.

Today, nothing has changed, only the "danger" that's responsible for causing fear is usually very different (and much less harmful). This is perfectly normal; even experienced presenters may often still feel nervous before delivering a presentation.

Luckily, coping with presentation nerves is indeed possible with some useful tips and some practice. Have in mind that your instincts are wrong in this situation, as there's actually no need for a fight or flight reaction. Focus on preparing oral presentations as best as you can, stand your ground, and simply try to communicate to the best of your abilities in the given situation.

Delivering an oral presentation in conferences and meetings can seem daunting. However, if delivered effectively, it can be an invaluable opportunity to showcase your work in front of peers as well as receive feedback on your project. In this “How to” article, we demonstrate how one can plan and successfully deliver an engaging oral presentation.

Giving an oral presentation at a scientific conference is an almost inevitable task at some point during your medical career. The prospect of presenting your original work to colleagues and peers, however, may be intimidating, and it can be difficult to know how to approach it. Nonetheless, it is important to remember that although daunting, an oral presentation is one of the best ways to get your work out there, and so should be looked upon as an exciting and invaluable opportunity.

Slide content

Although things may vary slightly depending on the type of research you are presenting, the typical structure is as follows:

• Opening slide (title of study, authors, institutions, and date)
• Methodology
• Discussion (including strengths and weaknesses of the study)

Conclusions

Picking out only the most important findings to include in your presentation is key and will keep it concise and easy to follow. This in turn will keep your viewers engaged, and more likely to understand and remember your presentation.

Psychological analysis of PowerPoint presentations, finds that 8 psychological principles are often violated 1 . One of these was the limited capacity of working memory, which can hold 4 units of information at any 1 time in most circumstances. Hence, too many points or concepts on a slide could be detrimental to the presenter’s desire to give information.

You can also help keep your audience engaged with images, which you can talk around, rather than lots of text. Video can also be useful, for example, a surgical procedure. However, be warned that IT can let you down when you need it most and you need to have a backup plan if the video fails. It’s worth coming to the venue early and testing it and resolving issues beforehand with the AV support staff if speaking at a conference.

Slide design and layout

It is important not to clutter your slides with too much text or too many pictures. An easy way to do this is by using the 5×5 rule. This means using no more than 5 bullet points per slide, with no more than 5 words per bullet point. It is also good to break up the text-heavy slides with ones including diagrams or graphs. This can also help to convey your results in a more visual and easy-to-understand way.

It is best to keep the slide design simple, as busy backgrounds and loud color schemes are distracting. Ensure that you use a uniform font and stick to the same color scheme throughout. As a general rule, a light-colored background with dark-colored text is easier to read than light-colored text on a dark-colored background. If you can use an image instead of text, this is even better.

A systematic review study of expert opinion papers demonstrates several key recommendations on how to effectively deliver medical research presentations 2 . These include:

• Keeping your slides simple
• Knowing your audience (pitching to the right level)
• Making eye contact
• Rehearsing the presentation
• Do not read from the slides
• Limiting the number of lines per slide
• Sticking to the allotted time

You should practice your presentation before the conference, making sure that you stick to the allocated time given to you. Oral presentations are usually short (around 8–10 min maximum), and it is, therefore, easy to go under or over time if you have not rehearsed. Aiming to spend around 1 minute per slide is usually a good guide. It is useful to present to your colleagues and seniors, allowing them to ask you questions afterwards so that you can be prepared for the sort of questions you may get asked at the conference. Knowing your research inside out and reading around the subject is advisable, as there may be experts watching you at the conference with more challenging questions! Make sure you re-read your paper the day before, or on the day of the conference to refresh your memory.

It is useful to bring along handouts of your presentation for those who may be interested. Rather than printing out miniature versions of your power point slides, it is better to condense your findings into a brief word document. Not only will this be easier to read, but you will also save a lot of paper by doing this!

Delivering the presentation

Having rehearsed your presentation beforehand, the most important thing to do when you get to the conference is to keep calm and be confident. Remember that you know your own research better than anyone else in the room! Be sure to take some deep breaths and speak at an appropriate pace and volume, making good eye contact with your viewers. If there is a microphone, don’t keep turning away from it as the audience will get frustrated if your voice keeps cutting in and out. Gesturing and using pointers when appropriate can be a really useful tool, and will enable you to emphasize your important findings.

Presenting tips

• Do not hide behind the computer. Come out to the center or side and present there.
• Maintain eye contact with the audience, especially the judges.
• Remember to pause every so often.
• Don’t clutter your presentation with verbal noise such as “umm,” “like,” or “so.” You will look more slick if you avoid this.
• Rhetorical questions once in a while can be useful in maintaining the audience’s attention.

When reaching the end of your presentation, you should slow down in order to clearly convey your key points. Using phases such as “in summary” and “to conclude” often prompts those who have drifted off slightly during your presentation start paying attention again, so it is a critical time to make sure that your work is understood and remembered. Leaving up your conclusions/summary slide for a short while after stopping speaking will give the audience time to digest the information. Conclude by acknowledging any fellow authors or assistants before thanking the audience for their attention and inviting any questions (as long as you have left sufficient time).

If asked a question, firstly thank the audience member, then repeat what they have asked to the rest of the listeners in case they didn’t hear the first time. Keep your answers short and succinct, and if unsure say that the questioner has raised a good point and that you will have to look into it further. Having someone else in the audience write down the question is useful for this.

The key points to remember when preparing for an oral presentation are:

• Keep your slides simple and concise using the 5×5 rule and images.
• When appropriate; rehearse timings; prepare answers to questions; speak slowly and use gestures/ pointers where appropriate; make eye contact with the audience; emphasize your key points at the end; make acknowledgments and thank the audience; invite questions and be confident but not arrogant.

Oral Presentations Purpose

An Oral Research Presentation is meant to showcase your research findings. A successful oral research presentation should: communicate the importance of your research; clearly state your findings and the analysis of those findings; prompt discussion between researcher and audience.  Below you will find information on how to create and give a successful oral presentation.  

Creating an Effective Presentation

Who has a harder job the speaker? Or, the audience?

Most people think speaker has the hardest job during an oral presentation, because they are having to stand up in a room full of people and give a presentation. However, if the speaker is not engaging and if the material is way outside of the audiences knowledge level, the audience can have a difficult job as well. Below you will find some tips on how to be an effective presenter and how to engage with your audience.

Organization of a Presentation  

Introduction/Beginning

How are you going to begin?  How are you going to get the attention of your audience? You need to take the time and think about how you are going to get started!

Here are some ways you could start:

• Ask the audience a question
• make a statement
• show them something

No matter how you start your presentation it needs to relate to your research and capture the audiences attention.  

Preview what you are going to discuss .  Audiences do not like to be manipulated or tricked. Tell the audience exactly what you are going to discuss, this will help them follow along.  *Do not say you are going to cover three points and then try to cover 8 points.

At the end of your introduction, the audience should feel like they know exactly what you are going to  discuss and exactly how you are going to get there.  

Body/Middle

Conclusion/End

Delivery and Communication

Eye Contact

Making eye contact is a great way to engage with your audience.  Eye contact should be no longer than 2-3 seconds per person.  Eye contact for much longer than that can begin to make the audience member feel uncomfortable.

Smiling lets attendees know you are happy to be there and that you are excited to talk with them about your project.

We all know that body language says a lot, so here are some things you should remember when giving your presentation.

• Stand with both feet on the floor, not with one foot crossed over the other. 
• Do not stand with your hands in your pockets, or with your arms crossed.
• Stand tall with confidence and own your space (remember you are the expert).  

Abbreviated Notes

Having a written set of notes or key points that you want to address can help prevent you from reading the poster. 

Speak Clearly

Sometimes when we get nervous we begin to talk fast and blur our words.  It is important that you make sure every word is distinct and clear. A great way to practice your speech is to say tongue twisters. 

Ten tiny tots tottered toward the shore

Literally literary. Literally literary.  Literally literary.

Sally soon saw that she should sew some sheets.

Avoid Fillers

Occasionally we pick up fillers that we are not aware of, such as um, like, well, etc. One way to get rid of fillers is to have a friend listen to your speech and every time you say a "filler" have that friend tap you on the arm or say your name.  This will bring the filler to light, then you can practice avoiding that filler.

Manage Anxiety

Many people get nervous when they are about to speak to a crowd of people.  Below are ways that you can manage your anxiety levels. 

• Practice, Practice, Practice - the more prepared you are the less nervous you will be.
• Recognize that anxiety is just a big shot of adrenalin.
• Take deep breaths before your presentation to calm you down. 

Components of an Oral Research Presentation

Introduction

The introduction section of your oral presentation should consist of 3 main parts.  

Part 1: Existing facts

In order to give audience members the "full picture", you first need to provide them with information about past research.  What facts already exist? What is already known about your research area?

Part 2: Shortcomings

Once you have highlighted past research and existing facts. You now need to address what is left to be known, or what shortcomings exist within the current information.  This should set the groundwork for your experiment.  Keep in mind, how does your research fill these gaps or help address these questions? 

Part 3: Purpose or Hypothesis

After you have addressed past/current research and have identified shortcomings/gaps, it is now time to address your research.  During this portion of the introduction you need to tell viewers why you are conducting your research experiement/study, and what you hope to accomplish by doing so. 

In this section you should share with your audience how you went about collecting and analyzing your data

Should include:

• Participants: Who or what was in the study?
• Materials/ measurements: what did you measure?
• Procedures: How did you do the study?
• Data-analysis: What analysis were conducted? 

This section contains FACTS – with no opinion, commentary or interpretation. Graphs, charts and images can be used to display data in a clear and organized way.  

Keep in mind when making figures:

• Make sure axis, treatments, and data sets are clearly labeled
• Strive for simplicity, especially in figure titles. 
• Know when to use what kind of graph
• Be careful with colors.

Interpretation and commentary takes place here. This section should give a clear summary of your findings. 

You should:

• Address the positive and negative aspects of you research
• Discuss how and if your research question was answered. 
• Highlight the novel and important findings
• Speculate on what could be occurring in your system 

Future Research

• State your goals
• Include information about why you believe research should go in the direction you are proposing
• Discuss briefly how you plan to implement the research goals, if you chose to do so.  

Why include References?

• It allows viewers to locate the material that you used, and can help viewers expand their knowledge of your research topic.  
• Indicates that you have conducted a thorough review of the literature and conducted your research from an informed perspective.
• Guards you against intellectual theft.  Ideas are considered intellectual property failure to cite someone's ideas can have serious consequences. 

Acknowledgements

This section is used to thank the people, programs and funding agencies that allowed you to perform your research.

Questions 

Allow for about 2-3 minutes at the end of your presentation for questions. 

It is important to be prepared. 

• Know why you conducted the study
• Be prepared to answer questions about why you chose a specific methodology

If you DO NOT know the answer to a question

Visual Aids

PowerPoints and other visual aids can be used to support what you are presenting about.

Power Point Slides and other visual aids can help support your presentation, however there are some things you should consider: 

• Do not overdo it . One big mistake that presenters make is they have  a slide for every single item they want to say. One way you can avoid this is by writing your presentation in Word first, instead of making a Power Point Presentation. By doing this you can type exactly what you want to say, and once your presentation is complete, you can create Power Point slides that help support your presentation. ​

Formula for number of visual aids : Length of presentation divided by 2 plus 1

example: 12 minute presentation should have no more than 7 slides.

• Does it add interest? 
• Does it prove? 
• Does it clarify?
• Do not read the text . Most people can read, and if they have the option of reading material themselves versus listen to you read it, they are going to read it themselves and then your voice becomes an annoyance. Also, when you are reading the text you are probably not engaging with the audience. 
• No more than 4-6 lines on a slide and no more than 4-6 words in a line.
• People should be able to read your slide in 6 seconds.

In the social and behavioral sciences, an oral presentation assignment involves an individual student or group of students verbally addressing an audience on a specific research-based topic, often utilizing slides to help audience members understand and retain what they both see and hear. The purpose is to inform, report, and explain the significance of research findings, and your critical analysis of those findings, within a specific period of time, often in the form of a reasoned and persuasive argument. Oral presentations are assigned to assess a student’s ability to organize and communicate relevant information  effectively to a particular audience. Giving an oral presentation is considered an important learning skill because the ability to speak persuasively in front of an audience is transferable to most professional workplace settings.

Preparing for Your Oral Presentation

In some classes, writing the research paper is only part of what is required in reporting the results your work. Your professor may also require you to give an oral presentation about your study. Here are some things to think about before you are scheduled to give a presentation.

1.  What should I say?

If your professor hasn't explicitly stated what the content of your presentation should focus on, think about what you want to achieve and what you consider to be the most important things that members of the audience should know about your research. Think about the following: Do I want to inform my audience, inspire them to think about my research, or convince them of a particular point of view? These questions will help frame how to approach your presentation topic.

2.  Oral communication is different from written communication

Your audience has just one chance to hear your talk; they can't "re-read" your words if they get confused. Focus on being clear, particularly if the audience can't ask questions during the talk. There are two well-known ways to communicate your points effectively, often applied in combination. The first is the K.I.S.S. method [Keep It Simple Stupid]. Focus your presentation on getting two to three key points across. The second approach is to repeat key insights: tell them what you're going to tell them [forecast], tell them [explain], and then tell them what you just told them [summarize].

3.  Think about your audience

Yes, you want to demonstrate to your professor that you have conducted a good study. But professors often ask students to give an oral presentation to practice the art of communicating and to learn to speak clearly and audibly about yourself and your research. Questions to think about include: What background knowledge do they have about my topic? Does the audience have any particular interests? How am I going to involve them in my presentation?

4.  Create effective notes

If you don't have notes to refer to as you speak, you run the risk of forgetting something important. Also, having no notes increases the chance you'll lose your train of thought and begin relying on reading from the presentation slides. Think about the best ways to create notes that can be easily referred to as you speak. This is important! Nothing is more distracting to an audience than the speaker fumbling around with notes as they try to speak. It gives the impression of being disorganized and unprepared.

NOTE:   A good strategy is to have a page of notes for each slide so that the act of referring to a new page helps remind you to move to the next slide. This also creates a natural pause that allows your audience to contemplate what you just presented.

Strategies for creating effective notes for yourself include the following:

• Choose a large, readable font [at least 18 point in Ariel ]; avoid using fancy text fonts or cursive text.
• Use bold text, underlining, or different-colored text to highlight elements of your speech that you want to emphasize. Don't over do it, though. Only highlight the most important elements of your presentation.
• Leave adequate space on your notes to jot down additional thoughts or observations before and during your presentation. This is also helpful when writing down your thoughts in response to a question or to remember a multi-part question [remember to have a pen with you when you give your presentation].
• Place a cue in the text of your notes to indicate when to move to the next slide, to click on a link, or to take some other action, such as, linking to a video. If appropriate, include a cue in your notes if there is a point during your presentation when you want the audience to refer to a handout.
• Spell out challenging words phonetically and practice saying them ahead of time. This is particularly important for accurately pronouncing people’s names, technical or scientific terminology, words in a foreign language, or any unfamiliar words.

Organizing the Content

In the process of organizing the content of your presentation, begin by thinking about what you want to achieve and how are you going to involve your audience in the presentation.

• Brainstorm your topic and write a rough outline. Don’t get carried away—remember you have a limited amount of time for your presentation.
• Organize your material and draft what you want to say [see below].
• Summarize your draft into key points to write on your presentation slides and/or note cards and/or handout.
• Prepare your visual aids.
• Rehearse your presentation and practice getting the presentation completed within the time limit given by your professor. Ask a friend to listen and time you.

GENERAL OUTLINE

I.  Introduction [may be written last]

• Capture your listeners’ attention . Begin with a question, an amusing story, a provocative statement, a personal story, or anything that will engage your audience and make them think. For example, "As a first-gen student, my hardest adjustment to college was the amount of papers I had to write...."
• State your purpose . For example, "I’m going to talk about..."; "This morning I want to explain…."
• Present an outline of your talk . For example, “I will concentrate on the following points: First of all…Then…This will lead to…And finally…"

II.  The Body

• Present your main points one by one in a logical order .
• Pause at the end of each point . Give people time to take notes, or time to think about what you are saying.
• Make it clear when you move to another point . For example, “The next point is that...”; “Of course, we must not forget that...”; “However, it's important to realize that....”
• Use clear examples to illustrate your points and/or key findings .
• If appropriate, consider using visual aids to make your presentation more interesting [e.g., a map, chart, picture, link to a video, etc.].

III.  The Conclusion

• Leave your audience with a clear summary of everything that you have covered.
• Summarize the main points again . For example, use phrases like: "So, in conclusion..."; "To recap the main issues...," "In summary, it is important to realize...."
• Restate the purpose of your talk, and say that you have achieved your aim : "My intention was ..., and it should now be clear that...."
• Don't let the talk just fizzle out . Make it obvious that you have reached the end of the presentation.
• Thank the audience, and invite questions : "Thank you. Are there any questions?"

NOTE: When asking your audience if anyone has any questions, give people time to contemplate what you have said and to formulate a question. It may seem like an awkward pause to wait ten seconds or so for someone to raise their hand, but it's frustrating to have a question come to mind but be cutoff because the presenter rushed to end the talk.

ANOTHER NOTE: If your last slide includes any contact information or other important information, leave it up long enough to ensure audience members have time to write the information down. Nothing is more frustrating to an audience member than wanting to jot something down, but the presenter closes the slides immediately after finishing.

Delivering Your Presentation

When delivering your presentation, keep in mind the following points to help you remain focused and ensure that everything goes as planned.

Pay Attention to Language!

• Keep it simple . The aim is to communicate, not to show off your vocabulary. Using complex words or phrases increases the chance of stumbling over a word and losing your train of thought.
• Emphasize the key points . Make sure people realize which are the key points of your study. Repeat them using different phrasing to help the audience remember them.
• Check the pronunciation of difficult, unusual, or foreign words beforehand . Keep it simple, but if you have to use unfamiliar words, write them out phonetically in your notes and practice saying them. This is particularly important when pronouncing proper names. Give the definition of words that are unusual or are being used in a particular context [e.g., "By using the term affective response, I am referring to..."].

Use Your Voice to Communicate Clearly

• Speak loud enough for everyone in the room to hear you . Projecting your voice may feel uncomfortably loud at first, but if people can't hear you, they won't try to listen. However, moderate your voice if you are talking in front of a microphone.
• Speak slowly and clearly . Don’t rush! Speaking fast makes it harder for people to understand you and signals being nervous.
• Avoid the use of "fillers." Linguists refer to utterances such as um, ah, you know, and like as fillers. They occur most often during transitions from one idea to another and, if expressed too much, are distracting to an audience. The better you know your presentation, the better you can control these verbal tics.
• Vary your voice quality . If you always use the same volume and pitch [for example, all loud, or all soft, or in a monotone] during your presentation, your audience will stop listening. Use a higher pitch and volume in your voice when you begin a new point or when emphasizing the transition to a new point.
• Speakers with accents need to slow down [so do most others]. Non-native speakers often speak English faster than we slow-mouthed native speakers, usually because most non-English languages flow more quickly than English. Slowing down helps the audience to comprehend what you are saying.
• Slow down for key points . These are also moments in your presentation to consider using body language, such as hand gestures or leaving the podium to point to a slide, to help emphasize key points.
• Use pauses . Don't be afraid of short periods of silence. They give you a chance to gather your thoughts, and your audience an opportunity to think about what you've just said.

Also Use Your Body Language to Communicate!

• Stand straight and comfortably . Do not slouch or shuffle about. If you appear bored or uninterested in what your talking about, the audience will emulate this as well. Wear something comfortable. This is not the time to wear an itchy wool sweater or new high heel shoes for the first time.
• Hold your head up . Look around and make eye contact with people in the audience [or at least pretend to]. Do not just look at your professor or your notes the whole time! Looking up at your your audience brings them into the conversation. If you don't include the audience, they won't listen to you.
• When you are talking to your friends, you naturally use your hands, your facial expression, and your body to add to your communication . Do it in your presentation as well. It will make things far more interesting for the audience.
• Don't turn your back on the audience and don't fidget! Neither moving around nor standing still is wrong. Practice either to make yourself comfortable. Even when pointing to a slide, don't turn your back; stand at the side and turn your head towards the audience as you speak.
• Keep your hands out of your pocket . This is a natural habit when speaking. One hand in your pocket gives the impression of being relaxed, but both hands in pockets looks too casual and should be avoided.

Interact with the Audience

• Be aware of how your audience is reacting to your presentation . Are they interested or bored? If they look confused, stop and ask them [e.g., "Is anything I've covered so far unclear?"]. Stop and explain a point again if needed.
• Check after highlighting key points to ask if the audience is still with you . "Does that make sense?"; "Is that clear?" Don't do this often during the presentation but, if the audience looks disengaged, interrupting your talk to ask a quick question can re-focus their attention even if no one answers.
• Do not apologize for anything . If you believe something will be hard to read or understand, don't use it. If you apologize for feeling awkward and nervous, you'll only succeed in drawing attention to the fact you are feeling awkward and nervous and your audience will begin looking for this, rather than focusing on what you are saying.
• Be open to questions . If someone asks a question in the middle of your talk, answer it. If it disrupts your train of thought momentarily, that's ok because your audience will understand. Questions show that the audience is listening with interest and, therefore, should not be regarded as an attack on you, but as a collaborative search for deeper understanding. However, don't engage in an extended conversation with an audience member or the rest of the audience will begin to feel left out. If an audience member persists, kindly tell them that the issue can be addressed after you've completed the rest of your presentation and note to them that their issue may be addressed later in your presentation [it may not be, but at least saying so allows you to move on].
• Be ready to get the discussion going after your presentation . Professors often want a brief discussion to take place after a presentation. Just in case nobody has anything to say or no one asks any questions, be prepared to ask your audience some provocative questions or bring up key issues for discussion.

Speaking Tip

Your First Words are Your Most Important Words!

Your introduction should begin with something that grabs the attention of your audience, such as, an interesting statistic, a brief narrative or story, or a bold assertion, and then clearly tell the audience in a well-crafted sentence what you plan to accomplish in your presentation. Your introductory statement should be constructed so as to invite the audience to pay close attention to your message and to give the audience a clear sense of the direction in which you are about to take them.

Lucas, Stephen. The Art of Public Speaking . 12th edition. Boston, MA: McGraw-Hill Higher Education, 2015.

Another Speaking Tip

Talk to Your Audience, Don't Read to Them!

A presentation is not the same as reading a prepared speech or essay. If you read your presentation as if it were an essay, your audience will probably understand very little about what you say and will lose their concentration quickly. Use notes, cue cards, or presentation slides as prompts that highlight key points, and speak to your audience . Include everyone by looking at them and maintaining regular eye-contact [but don't stare or glare at people]. Limit reading text to quotes or to specific points you want to emphasize.

24 Oral Presentations

Many academic courses require students to present information to their peers and teachers in a classroom setting. This is usually in the form of a short talk, often, but not always, accompanied by visual aids such as a power point. Students often become nervous at the idea of speaking in front of a group.

This chapter is divided under five headings to establish a quick reference guide for oral presentations.

A beginner, who may have little or no experience, should read each section in full.

For the intermediate learner, who has some experience with oral presentations, review the sections you feel you need work on.

The Purpose of an Oral Presentation

Generally, oral presentation is public speaking, either individually or as a group, the aim of which is to provide information, entertain, persuade the audience, or educate. In an academic setting, oral presentations are often assessable tasks with a marking criteria. Therefore, students are being evaluated on their capacity to speak and deliver relevant information within a set timeframe. An oral presentation differs from a speech in that it usually has visual aids and may involve audience interaction; ideas are both shown and explained . A speech, on the other hand, is a formal verbal discourse addressing an audience, without visual aids and audience participation.

Types of Oral Presentations

Individual presentation.

• Breathe and remember that everyone gets nervous when speaking in public. You are in control. You’ve got this!
• Know your content. The number one way to have a smooth presentation is to know what you want to say and how you want to say it. Write it down and rehearse it until you feel relaxed and confident and do not have to rely heavily on notes while speaking.
• Eliminate ‘umms’ and ‘ahhs’ from your oral presentation vocabulary. Speak slowly and clearly and pause when you need to. It is not a contest to see who can race through their presentation the fastest or fit the most content within the time limit. The average person speaks at a rate of 125 words per minute. Therefore, if you are required to speak for 10 minutes, you will need to write and practice 1250 words for speaking. Ensure you time yourself and get it right.
• Ensure you meet the requirements of the marking criteria, including non-verbal communication skills. Make good eye contact with the audience; watch your posture; don’t fidget.
• Know the language requirements. Check if you are permitted to use a more casual, conversational tone and first-person pronouns, or do you need to keep a more formal, academic tone?

Group Presentation

• All of the above applies, however you are working as part of a group. So how should you approach group work?
• Firstly, if you are not assigned to a group by your lecturer/tutor, choose people based on their availability and accessibility. If you cannot meet face-to-face you may schedule online meetings.
• Get to know each other. It’s easier to work with friends than strangers.
• Also consider everyone’s strengths and weaknesses. This will involve a discussion that will often lead to task or role allocations within the group, however, everyone should be carrying an equal level of the workload.
• Some group members may be more focused on getting the script written, with a different section for each team member to say. Others may be more experienced with the presentation software and skilled in editing and refining power point slides so they are appropriate for the presentation. Use one visual aid (one set of power point slides) for the whole group. Take turns presenting information and ideas.
• Be patient and tolerant with each other’s learning style and personality. Do not judge people in your group based on their personal appearance, sexual orientation, gender, age, or cultural background.
• Rehearse as a group, more than once. Keep rehearsing until you have seamless transitions between speakers. Ensure you thank the previous speaker and introduce the one following you. If you are rehearsing online, but have to present in-person, try to schedule some face-to-face time that will allow you to physically practice using the technology and classroom space of the campus.

Writing Your Presentation

Approach the oral presentation task just as you would any other assignment. Review the available topics, do some background reading and research to ensure you can talk about the topic for the appropriate length of time and in an informed manner. Break the question down as demonstrated in Chapter 17 Breaking Down an Assignment. Where it differs from writing an essay is that the information in the written speech must align with the visual aid. Therefore, with each idea, concept or new information you write, think about how this might be visually displayed through minimal text and the occasional use of images. Proceed to write your ideas in full, but consider that not all information will end up on a power point slide. After all, it is you who are doing the presenting , not the power point. Your presentation skills are being evaluated; this may include a small percentage for the actual visual aid. This is also why it is important that EVERYONE has a turn at speaking during the presentation, as each person receives their own individual grade.

Using Visual Aids

A whole chapter could be written about the visual aids alone, therefore I will simply refer to the key points as noted by my.UQ

To keep your audience engaged and help them to remember what you have to say, you may want to use visual aids, such as slides.

When designing slides for your presentation, make sure:

• any text is brief, grammatically correct and easy to read. Use dot points and space between lines, plus large font size (18-20 point).
• Resist the temptation to use dark slides with a light-coloured font; it is hard on the eyes
• if images and graphs are used to support your main points, they should be non-intrusive on the written work

Images and Graphs

• Your audience will respond better to slides that deliver information quickly – images and graphs are a good way to do this. However, they are not always appropriate or necessary.

When choosing images, it’s important to find images that:

• support your presentation and aren’t just decorative
• are high quality, however, using large HD picture files can make the power point file too large overall for submission via Turnitin
• you have permission to use (Creative Commons license, royalty-free, own images, or purchased)
• suggested sites for free-to-use images: Openclipart – Clipping Culture ; Beautiful Free Images & Pictures | Unsplash ; Pxfuel – Royalty free stock photos free download ; When we share, everyone wins – Creative Commons

This is a general guide. The specific requirements for your course may be different. Make sure you read through any assignment requirements carefully and ask your lecturer or tutor if you’re unsure how to meet them.

Using Visual Aids Effectively

Too often, students make an impressive power point though do not understand how to use it effectively to enhance their presentation.

• Rehearse with the power point.
• Keep the slides synchronized with your presentation; change them at the appropriate time.
• Refer to the information on the slides. Point out details; comment on images; note facts such as data.
• Don’t let the power point just be something happening in the background while you speak.
• Write notes in your script to indicate when to change slides or which slide number the information applies to.
• Pace yourself so you are not spending a disproportionate amount of time on slides at the beginning of the presentation and racing through them at the end.
• Practice, practice, practice.

Nonverbal Communication

It is clear by the name that nonverbal communication are the ways that we communicate without speaking. Many people are already aware of this, however here are a few tips that relate specifically to oral presentations.

Being confident and looking confident are two different things. Fake it until you make it.

• Avoid slouching or leaning – standing up straight instantly gives you an air of confidence.
• Move! When you’re glued to one spot as a presenter, you’re not perceived as either confident or dynamic. Use the available space effectively, though do not exaggerate your natural movements so you look ridiculous.
• If you’re someone who “speaks with their hands”, resist the urge to constantly wave them around. They detract from your message. Occasional gestures are fine.
• Be animated, but don’t fidget. Ask someone to watch you rehearse and identify if you have any nervous, repetitive habits you may be unaware of, for example, constantly touching or ‘finger-combing’ your hair, rubbing your face.
• Avoid ‘voice fidgets’ also. If you needs to cough or clear your throat, do so once then take a drink of water.
• Avoid distractions. No phone turned on. Water available but off to one side.
• Keep your distance. Don’t hover over front-row audience members; this can be intimidating.
• Have a cheerful demeaner. You do not need to grin like a Cheshire cat throughout the presentation, yet your facial expression should be relaxed and welcoming.
• Maintain an engaging TONE in your voice. Sometimes it’s not what you’re saying that is putting your audience to sleep, it’s your monotonous tone. Vary your tone and pace.
• Don’t read your presentation – PRESENT it! Internalize your script so you can speak with confidence and only occasionally refer to your notes if needed.
• Lastly, make good eye contact with your audience members so they know you are talking with them, not at them. You’re having a conversation. Watch the link below for some great speaking tips, including eye contact.

How to Structure your Presentation, with Examples

August 3, 2018 - Dom Barnard

For many people the thought of delivering a presentation is a daunting task and brings about a  great deal of nerves . However, if you take some time to understand how effective presentations are structured and then apply this structure to your own presentation, you’ll appear much more confident and relaxed.

Here is our complete guide for structuring your presentation, with examples at the end of the article to demonstrate these points.

Why is structuring a presentation so important?

If you’ve ever sat through a great presentation, you’ll have left feeling either inspired or informed on a given topic. This isn’t because the speaker was the most knowledgeable or motivating person in the world. Instead, it’s because they know how to structure presentations – they have crafted their message in a logical and simple way that has allowed the audience can keep up with them and take away key messages.

Research has supported this, with studies showing that audiences retain structured information  40% more accurately  than unstructured information.

In fact, not only is structuring a presentation important for the benefit of the audience’s understanding, it’s also important for you as the speaker. A good structure helps you remain calm, stay on topic, and avoid any awkward silences.

What will affect your presentation structure?

Generally speaking, there is a natural flow that any decent presentation will follow which we will go into shortly. However, you should be aware that all presentation structures will be different in their own unique way and this will be due to a number of factors, including:

• Whether you need to deliver any demonstrations
• How  knowledgeable the audience  already is on the given subject
• How much interaction you want from the audience
• Any time constraints there are for your talk
• What setting you are in
• Your ability to use any kinds of visual assistance

Before choosing the presentation’s structure answer these questions first:

• What is your presentation’s aim?
• Who are the audience?
• What are the main points your audience should remember afterwards?

When reading the points below, think critically about what things may cause your presentation structure to be slightly different. You can add in certain elements and add more focus to certain moments if that works better for your speech.

What is the typical presentation structure?

This is the usual flow of a presentation, which covers all the vital sections and is a good starting point for yours. It allows your audience to easily follow along and sets out a solid structure you can add your content to.

1. Greet the audience and introduce yourself

Before you start delivering your talk, introduce yourself to the audience and clarify who you are and your relevant expertise. This does not need to be long or incredibly detailed, but will help build an immediate relationship between you and the audience. It gives you the chance to briefly clarify your expertise and why you are worth listening to. This will help establish your ethos so the audience will trust you more and think you’re credible.

Read our tips on  How to Start a Presentation Effectively

2. Introduction

In the introduction you need to explain the subject and purpose of your presentation whilst gaining the audience’s interest and confidence. It’s sometimes helpful to think of your introduction as funnel-shaped to help filter down your topic:

• Introduce your general topic
• Explain your topic area
• State the issues/challenges in this area you will be exploring
• State your presentation’s purpose – this is the basis of your presentation so ensure that you provide a statement explaining how the topic will be treated, for example, “I will argue that…” or maybe you will “compare”, “analyse”, “evaluate”, “describe” etc.
• Provide a statement of what you’re hoping the outcome of the presentation will be, for example, “I’m hoping this will be provide you with…”
• Show a preview of the organisation of your presentation

In this section also explain:

• The length of the talk.
• Signal whether you want audience interaction – some presenters prefer the audience to ask questions throughout whereas others allocate a specific section for this.
• If it applies, inform the audience whether to take notes or whether you will be providing handouts.

The way you structure your introduction can depend on the amount of time you have been given to present: a  sales pitch  may consist of a quick presentation so you may begin with your conclusion and then provide the evidence. Conversely, a speaker presenting their idea for change in the world would be better suited to start with the evidence and then conclude what this means for the audience.

Keep in mind that the main aim of the introduction is to grab the audience’s attention and connect with them.

3. The main body of your talk

The main body of your talk needs to meet the promises you made in the introduction. Depending on the nature of your presentation, clearly segment the different topics you will be discussing, and then work your way through them one at a time – it’s important for everything to be organised logically for the audience to fully understand. There are many different ways to organise your main points, such as, by priority, theme, chronologically etc.

• Main points should be addressed one by one with supporting evidence and examples.
• Before moving on to the next point you should provide a mini-summary.
• Links should be clearly stated between ideas and you must make it clear when you’re moving onto the next point.
• Allow time for people to take relevant notes and stick to the topics you have prepared beforehand rather than straying too far off topic.

When planning your presentation write a list of main points you want to make and ask yourself “What I am telling the audience? What should they understand from this?” refining your answers this way will help you produce clear messages.

4. Conclusion

In presentations the conclusion is frequently underdeveloped and lacks purpose which is a shame as it’s the best place to reinforce your messages. Typically, your presentation has a specific goal – that could be to convert a number of the audience members into customers, lead to a certain number of enquiries to make people knowledgeable on specific key points, or to motivate them towards a shared goal.

Regardless of what that goal is, be sure to summarise your main points and their implications. This clarifies the overall purpose of your talk and reinforces your reason for being there.

Follow these steps:

• Signal that it’s nearly the end of your presentation, for example, “As we wrap up/as we wind down the talk…”
• Restate the topic and purpose of your presentation – “In this speech I wanted to compare…”
• Summarise the main points, including their implications and conclusions
• Indicate what is next/a call to action/a thought-provoking takeaway
• Move on to the last section

5. Thank the audience and invite questions

Conclude your talk by thanking the audience for their time and invite them to  ask any questions  they may have. As mentioned earlier, personal circumstances will affect the structure of your presentation.

Many presenters prefer to make the Q&A session the key part of their talk and try to speed through the main body of the presentation. This is totally fine, but it is still best to focus on delivering some sort of initial presentation to set the tone and topics for discussion in the Q&A.

Other common presentation structures

The above was a description of a basic presentation, here are some more specific presentation layouts:

Demonstration

Use the demonstration structure when you have something useful to show. This is usually used when you want to show how a product works. Steve Jobs frequently used this technique in his presentations.

• Explain why the product is valuable.
• Describe why the product is necessary.
• Explain what problems it can solve for the audience.
• Demonstrate the product  to support what you’ve been saying.
• Make suggestions of other things it can do to make the audience curious.

Problem-solution

This structure is particularly useful in persuading the audience.

• Briefly frame the issue.
• Go into the issue in detail showing why it ‘s such a problem. Use logos and pathos for this – the logical and emotional appeals.
• Provide the solution and explain why this would also help the audience.
• Call to action – something you want the audience to do which is straightforward and pertinent to the solution.

Storytelling

As well as incorporating  stories in your presentation , you can organise your whole presentation as a story. There are lots of different type of story structures you can use – a popular choice is the monomyth – the hero’s journey. In a monomyth, a hero goes on a difficult journey or takes on a challenge – they move from the familiar into the unknown. After facing obstacles and ultimately succeeding the hero returns home, transformed and with newfound wisdom.

Storytelling for Business Success  webinar , where well-know storyteller Javier Bernad shares strategies for crafting compelling narratives.

Another popular choice for using a story to structure your presentation is in media ras (in the middle of thing). In this type of story you launch right into the action by providing a snippet/teaser of what’s happening and then you start explaining the events that led to that event. This is engaging because you’re starting your story at the most exciting part which will make the audience curious – they’ll want to know how you got there.

• Great storytelling: Examples from Alibaba Founder, Jack Ma

Remaining method

The remaining method structure is good for situations where you’re presenting your perspective on a controversial topic which has split people’s opinions.

• Go into the issue in detail showing why it’s such a problem – use logos and pathos.
• Rebut your opponents’ solutions  – explain why their solutions could be useful because the audience will see this as fair and will therefore think you’re trustworthy, and then explain why you think these solutions are not valid.
• After you’ve presented all the alternatives provide your solution, the remaining solution. This is very persuasive because it looks like the winning idea, especially with the audience believing that you’re fair and trustworthy.

Transitions

When delivering presentations it’s important for your words and ideas to flow so your audience can understand how everything links together and why it’s all relevant. This can be done  using speech transitions  which are words and phrases that allow you to smoothly move from one point to another so that your speech flows and your presentation is unified.

Transitions can be one word, a phrase or a full sentence – there are many different forms, here are some examples:

Moving from the introduction to the first point

Signify to the audience that you will now begin discussing the first main point:

• Now that you’re aware of the overview, let’s begin with…
• First, let’s begin with…
• I will first cover…
• My first point covers…
• To get started, let’s look at…

Shifting between similar points

Move from one point to a similar one:

• In the same way…
• Likewise…
• Equally…
• This is similar to…
• Similarly…

Internal summaries

Internal summarising consists of summarising before moving on to the next point. You must inform the audience:

• What part of the presentation you covered – “In the first part of this speech we’ve covered…”
• What the key points were – “Precisely how…”
• How this links in with the overall presentation – “So that’s the context…”
• What you’re moving on to – “Now I’d like to move on to the second part of presentation which looks at…”

Physical movement

You can move your body and your standing location when you transition to another point. The audience find it easier to follow your presentation and movement will increase their interest.

A common technique for incorporating movement into your presentation is to:

• Start your introduction by standing in the centre of the stage.
• For your first point you stand on the left side of the stage.
• You discuss your second point from the centre again.
• You stand on the right side of the stage for your third point.
• The conclusion occurs in the centre.

Key slides for your presentation

Slides are a useful tool for most presentations: they can greatly assist in the delivery of your message and help the audience follow along with what you are saying. Key slides include:

• An intro slide outlining your ideas
• A  summary slide  with core points to remember
• High quality image slides to supplement what you are saying

There are some presenters who choose not to use slides at all, though this is more of a rarity. Slides can be a powerful tool if used properly, but the problem is that many fail to do just that. Here are some golden rules to follow when using slides in a presentation:

• Don’t over fill them  – your slides are there to assist your speech, rather than be the focal point. They should have as little information as possible, to avoid distracting people from your talk.
• A picture says a thousand words  – instead of filling a slide with text, instead, focus on one or two images or diagrams to help support and explain the point you are discussing at that time.
• Make them readable  – depending on the size of your audience, some may not be able to see small text or images, so make everything large enough to fill the space.
• Don’t rush through slides  – give the audience enough time to digest each slide.

Guy Kawasaki, an entrepreneur and author, suggests that slideshows should follow a  10-20-30 rule :

• There should be a maximum of 10 slides – people rarely remember more than one concept afterwards so there’s no point overwhelming them with unnecessary information.
• The presentation should last no longer than 20 minutes as this will leave time for questions and discussion.
• The font size should be a minimum of 30pt because the audience reads faster than you talk so less information on the slides means that there is less chance of the audience being distracted.

Here are some additional resources for slide design:

• 7 design tips for effective, beautiful PowerPoint presentations
• 11 design tips for beautiful presentations
• 10 tips on how to make slides that communicate your idea

Group Presentations

Group presentations are structured in the same way as presentations with one speaker but usually require more rehearsal and practices.  Clean transitioning between speakers  is very important in producing a presentation that flows well. One way of doing this consists of:

• Briefly recap on what you covered in your section: “So that was a brief introduction on what health anxiety is and how it can affect somebody”
• Introduce the next speaker in the team and explain what they will discuss: “Now Elnaz will talk about the prevalence of health anxiety.”
• Then end by looking at the next speaker, gesturing towards them and saying their name: “Elnaz”.
• The next speaker should acknowledge this with a quick: “Thank you Joe.”

From this example you can see how the different sections of the presentations link which makes it easier for the audience to follow and remain engaged.

Example of great presentation structure and delivery

Having examples of great presentations will help inspire your own structures, here are a few such examples, each unique and inspiring in their own way.

How Google Works – by Eric Schmidt

This presentation by ex-Google CEO  Eric Schmidt  demonstrates some of the most important lessons he and his team have learnt with regards to working with some of the most talented individuals they hired. The simplistic yet cohesive style of all of the slides is something to be appreciated. They are relatively straightforward, yet add power and clarity to the narrative of the presentation.

Start with why – by Simon Sinek

Since being released in 2009, this presentation has been viewed almost four million times all around the world. The message itself is very powerful, however, it’s not an idea that hasn’t been heard before. What makes this presentation so powerful is the simple message he is getting across, and the straightforward and understandable manner in which he delivers it. Also note that he doesn’t use any slides, just a whiteboard where he creates a simple diagram of his opinion.

The Wisdom of a Third Grade Dropout – by Rick Rigsby

Here’s an example of a presentation given by a relatively unknown individual looking to inspire the next generation of graduates. Rick’s presentation is unique in many ways compared to the two above. Notably, he uses no visual prompts and includes a great deal of humour.

However, what is similar is the structure he uses. He first introduces his message that the wisest man he knew was a third-grade dropout. He then proceeds to deliver his main body of argument, and in the end, concludes with his message. This powerful speech keeps the viewer engaged throughout, through a mixture of heart-warming sentiment, powerful life advice and engaging humour.

As you can see from the examples above, and as it has been expressed throughout, a great presentation structure means analysing the core message of your presentation. Decide on a key message you want to impart the audience with, and then craft an engaging way of delivering it.

By preparing a solid structure, and  practising your talk  beforehand, you can walk into the presentation with confidence and deliver a meaningful message to an interested audience.

It’s important for a presentation to be well-structured so it can have the most impact on your audience. An unstructured presentation can be difficult to follow and even frustrating to listen to. The heart of your speech are your main points supported by evidence and your transitions should assist the movement between points and clarify how everything is linked.

Research suggests that the audience remember the first and last things you say so your introduction and conclusion are vital for reinforcing your points. Essentially, ensure you spend the time structuring your presentation and addressing all of the sections.

• GUILLAIN-BARRE SYNDROME

Case presentation

A man in his mid-50s was admitted to hospital after falling and fracturing his L2 and L4 vertebrae. He had a history of intestinal occlusion 20 years before that had resolved with conservative treatment in his country of origin, Peru. CT scan of head, abdomen and pelvis were normal.

He promptly became haemodynamically unstable, developing hypotension (blood pressure 70/40 mm Hg), tachycardia (pulse 134 bpm) and fever (38.7°C), requiring intensive care unit admission for 3 days. An exploratory laparotomy found nothing pathological. His hyponatraemia (119 mmol/L) continued.

Two weeks after discharge from the intensive care unit, he developed numbness of his proximal lower limbs and trunk, progressing after 2 days to proximal weakness of all four limbs, with loss of deep tendon reflexes. He had no sphincter disturbance, facial numbness or weakness, no diplopia or other cranial nerves abnormalities. There was no fever or other features of infection. MR scan of brain showed no acute intracranial pathology and MR scan of spine showed only a fracture of the upper plate of L2.

He was admitted into the neurology department. On examination, he had a tachycardia (100 bpm). There was proximal muscle weakness, with moderate resistance in both arms and only movement against gravity in both legs. Reflexes were reduced in the upper limbs but absent in the lower limbs. He had hypoaesthesia of the trunk and proximal limbs, but no sensory level.

Questions for consideration

What are the most likely diagnoses and what tests would you perform to confirm it?

Diagnostic assessment

With his progressive symptoms of ascending sensory and motor problems affecting the limbs and trunk, with lost tendon reflexes, normal neuroimaging, we suspected Guillain-Barré syndrome.

Table 1 shows his relevant investigation results.

• View inline

Table results

Given the EMG findings and the mild cerebrospinal fluid albuminocytological dissociation, we suspected an axonal form of Guillain-Barré syndrome, and planned his first plasma exchange session.

Only 48 hours after admission into neurology, he developed significant haemodynamic instability (tachycardia 120 bpm and hypotension of 90/60 mmHg) with respiratory distress manifesting as excessive inspiratory muscle use, marked paradoxical breathing and inability to handle secretions or to cough. He required orotracheal intubation and readmission to the intensive care unit. His motor symptoms worsened slowly such that his proximal muscles showed only visible contraction, his distal arms moved against gravity and his distal legs moved against moderate resistance. The sensory alteration and global areflexia persisted.

There was no clinical improvement despite four sessions of plasma exchange on alternate days.

Given his clinical evolution and lack of treatment response, what other diagnosis and/or clinical management would you consider?

Differential diagnosis

Given the lack of improvement and atypical features including proximal sensorimotor distribution and prominent dysautonomia, we considered other causes of weakness after discharge from the intensive care unit 1 and paralytic Guillain-Barré syndrome mimics 2 3 :

Other causes of acute neuropathy:

Thiamine deficiency : although typically with a distal impairment, and rarely causing respiratory muscle weakness (and despite no history of chronic alcohol use), this was possible given the perioperative fasting before clinical onset.

Vasculitic neuropathy : this typically presents with multifocal involvement and focal pain in the area of weakness, and so seemed unlikely. Nevertheless, an autoimmunity panel and chest X-ray were arranged and were normal. Nerve biopsy was considered but postponed.

Malignancy or oncological treatments such as immunotherapy : there was no history of these.

Autoimmune nodopathies , particularly the IgG1 or IgG3 pan-neurofascinopathy, were considered possible.

Toxic and metabolic causes. After excluding more prevalent causes, we considered mainly acute intermittent porphyria and toxic causes such as lead 4 and arsenic poisoning, especially given the prior gastrointestinal symptoms and multisystem involvement.

Refsum’s disease is rare and typically accompanied by cerebellar ataxia and retinitis pigmentosa but was also considered.

Other non-neuropathic causes: traumatic and vascular myelopathy were excluded out by MR scan and MR angiogram of spine. Acute anterior horn cell infections, neuromuscular-plaque disorders and muscle disorders seemed unlikely with this clinical presentation and laboratory results.

Given the prior symptoms of prodromal confusion, abdominal pain, dysautonomia with persistent hyponatraemia, predominant proximal motor involvement and the ‘bathing-suit’ distribution of sensory symptoms, we suspected acute intermittent porphyria.

Question for consideration

When should neurologists suspect acute intermittent porphyria?

How would you diagnose and treat this patient?

Treatment and follow up

Acute intermittent porphyria is a disorder of haem synthesis caused by an inherited partial deficiency in the third enzyme in this synthetic pathway, porphobilinogen deaminase, 5 also known as hydroxymethylbilane synthase ( figure 1 ). This autosomal dominant condition leads to the accumulation of certain precursor chemicals including porphobilinogen and delta-aminolevulinic acid (ALA), presumed to be neurotoxic. Acute attacks can be triggered by inducing ALA synthase-1, the rate-limiting enzyme step, thus causing hepatic overproduction of porphyrin precursors. The pathogenesis is probably mediated through both the neurotoxicity of these precursors and the neuronal reduction in haem proteins.

Biochemical synthesis pathway of haem in the liver. A series of eight enzymatic processes lead to the intracellular haem synthesis. A main enzyme is ALA synthase-1, whose induction by different drugs or feeding states may lead to overproduction of haem precursors; in acute intermittent porphyria, given the defect in PBGD enzymatic function, these haem precursors may accumulate and cause a clinical attack. ALA synthase-1 is partly inhibited by negative feedback (in green) regulation by haem, and is the therapeutic target of girosivan (in green). Enzymes are in blue, haem precursors in black, AIP in red. AIP, acute intermittent porphyria; ALA, aminolevulinic acid. Created by L Maure with Biorender.com.

Inducers of ALA synthase-1 include certain medications 6 particularly those that induce the cytochrome P-450 enzyme system. Inducing these enzymes depletes haem by increasing its breakdown, diverting its precursors to enzyme synthesis and increasing metabolic demands for haem; the haem depletion in turn induces ALA synthase-1. Other common inducers are alcohol, hormonal imbalance (progesterone), other causes of iron deficiency and dieting, including most hypocaloric nutrition given at regular hospitalisation or, as in this case, peri-operative fasting.

The porphyrias comprise a group of eight disorders of haem synthesis ( figure 1 ), 5 each resulting from a specific enzyme defect in the biosynthesis pathway, and leading to the accumulation of haem intermediates. 7 Acute intermittent porphyria is the acute type most often encountered in clinical practice. While most commonly affecting young woman (80%–90%), it can males and females of all ages.

Neurological symptoms often involve direct central nervous system injury, manifesting as seizures (20%), encephalopathy or neuropsychiatric features, but can also present as a motor-predominant axonal neuropathy. 8 Acute intermittent porphyria should be considered in people with atypical Guillain-Barré syndrome.

Porphyric neuropathy predominantly affects the proximal limbs, especially the upper limbs and is often asymmetrical. Typically, there is associated pain or paraesthesia in a bathing suit distribution involving the torso and proximal limbs. Patients may have a history of abdominal disturbances with non-informative diagnostic workups, prodromal anxiety, confusion or psychosis, prominent dysautonomia and hyponatraemia. All these features again stress the importance of considering porphyria among the differential diagnosis of Guillain-Barré syndrome ( table 2 ).

Differences and similarities between Guillain-Barré syndrome and acute intermittent porphyria

Once clinically suspected, as in this case, acute intermittent porphyria is established from the presentation with a compatible acute clinical syndrome and elevated excretion of urinary porphobilinogen during the attack:

The Hoesch test is a qualitative test that is positive at urinary porphobilinogen concentrations of >9 mg/L. The test requires mixing Ehrlich’s reagent (20 g of p-dimethylaminobenzaldehyde in 1000 mL of 6N hydrochloric acid) with 2–3 drops of the patient’s urine. It is important to protect it from light as porphobilinogen exposed to light can oxidise into porphobilin, giving the urine a darker aspect. The reaction between Ehrlich’s reagent in acid solution and porphobilinogen forms a pink colour ( figure 2 ).

Positive Hoesch test (described in section 4). The pink colour of the urine is formed by the reaction of porphobilinogen and Erlich’s reagent.

Another recommended diagnostic tool is a quantified measure of porphobilinogen . Porphobilinogen increases substantially during an attack to 10–150 times the upper limit of the normal (or 20–300 mg per gram of creatine—normal 0–2). The test can be performed in a random sample with the result normalised per gram of urine creatine; a 24-hour urine collection is not required. Patients with increased urinary porphobilinogen then require further investigations. Note however, that porphobilinogen concentrations can normalise between attacks.

This patient’s porphyrins in a 24 hours urine sample, showed an elevated coproporphyrin 946.49 µg/24 hours (normal ≤150), uroporphyrin 426.60 µg/24 hours (normal ≤50). A spot urine sample showed a positive Hoesch test 9 ( figure 2 ), thus establishing elevated pathogenic concentrations of porphobilinogen in urine.

He had normal blood concentrations of fractionated porphyrins, protoporphyrin IX as well as faecal coproporphyrins, uroporphyrins and protoporphyrins. We excluded lead intoxication, 4 even though this was unlikely.

A suspected acute attack 10 should be treated immediately to prevent the hepatic overproduction of haem precursors. This includes infusing haem preparations, eliminating precipitating factors, high loading with carbohydrate—since dextrose inhibits ALA synthase-1—and giving supportive treatment. Also recommended are (if needed) antiemetics, analgesics and antiseizure medication (levetiracetam or gabapentin). There are promising results in preventing attacks and reducing the frequency and severity of symptoms using gyvosiran, a small interfering RNA therapy that specifically targets ALA synthase-1. 11 We started intravenous glucose and haemin infusions (4 mg/kg for 4 days), and stopped any potential precipitants.

The patient’s respiratory and dysautonomic symptoms gradually improved, and he was discharged from intensive care 10 days after starting specific treatment. His sensory symptoms quickly recovered; however, his motor improvement was slower, with persisting tetraparesis a month after discharge from the intensive care unit. He was admitted into a rehabilitation centre and re-evaluated 3 months later, at which time he could walk without assistance, but with residual upper limb weakness. With continued carbohydrate loading and avoiding porphyrinogenic triggers, he has had no new attacks since.

Acute intermittent porphyria has a variable prognosis. Although the weakness completely resolves in most patients over about 12 months, some do not fully recover. Potential issues (with screening implications) include hypertension, renal insufficiency, chronic pain, depression and an increased risk of hepatocellular carcinoma. It is also important to consider genetic assessment of family members at risk.

A genetic test finally confirmed that this patient had a known pathogenic heterozygotic mutation in hydroxymethylbilane synthase, also known as porphobilinogen deaminase ( figure 2 ), the c.331>A variant, causing his acute intermittent porphyria.

Some types of porphyria may have a higher prevalence than is generally assumed, and neurologists need to maintain a high index of clinical suspicion to diagnose this often treatable disease.

Common errors that might lead clinicians to miss the diagnosis include:

Ignoring clues in the history that may be key clinical information, such as previous gastrointestinal symptoms.

Dismissing symptoms at onset such as mild confusion or pain, and wrongly attributing this to medication side effects or psychosomatic causes.

Overlooking possible triggers before neurological symptom onset.

In this case, two additional unusual features delayed our diagnosis in the first few days, namely the patient’s age and sex, serving as a reminder that porphyria is not exclusive to one demographic. Another unusual feature was the prominent hypotension, given that acute intermittent porphyria more often leads to hypertension. 5

The diagnosis of acute intermittent porphyria is challenging and clinicians must be aware of its varied clinical presentations to avoid its fatal consequences. The prognosis correlates with the time to diagnosis of an acute attack and time to starting treatment. Clinicians clearly need to maintain a high threshold of suspicion, and to include porphyric neuropathy in the differential diagnosis of Guillain-Barré syndrome.

Acute Intermittent porphyria is a rare but treatable cause of predominantly axonal neuropathy; its diagnosis requires a high index of clinical suspicion.

In an acute neuropathy, key clinical information that might suggest acute intermittent porphyria includes abdominal pain (previous or present), mild-to-severe central nervous system involvement including altered affect, confusion and/or seizures, and a predominantly proximal motor neuropathy with bathing-suit distribution of sensory change.

Acute intermittent porphyria is confirmed with a quantified analysis of porphobilinogen, and managed by avoiding precipitant medications and starting intravenous haem as soon as possible.

The Neural Information Processing Systems Foundation is a non-profit corporation whose purpose is to foster the exchange of research advances in Artificial Intelligence and Machine Learning, principally by hosting an annual interdisciplinary academic conference with the highest ethical standards for a diverse and inclusive community.

About the Conference

The conference was founded in 1987 and is now a multi-track interdisciplinary annual meeting that includes invited talks, demonstrations, symposia, and oral and poster presentations of refereed papers. Along with the conference is a professional exposition focusing on machine learning in practice, a series of tutorials, and topical workshops that provide a less formal setting for the exchange of ideas.
