How to Write a Dissertation | A Guide to Structure & Content

A dissertation or thesis is a long piece of academic writing based on original research, submitted as part of an undergraduate or postgraduate degree.

The structure of a dissertation depends on your field, but it is usually divided into at least four or five chapters (including an introduction and conclusion chapter).

The most common dissertation structure in the sciences and social sciences includes:

An introduction to your topic
A literature review that surveys relevant sources
An explanation of your methodology
An overview of the results of your research
A discussion of the results and their implications
A conclusion that shows what your research has contributed

Dissertations in the humanities are often structured more like a long essay , building an argument by analysing primary and secondary sources . Instead of the standard structure outlined here, you might organise your chapters around different themes or case studies.

Other important elements of the dissertation include the title page , abstract , and reference list . If in doubt about how your dissertation should be structured, always check your department’s guidelines and consult with your supervisor.

Be assured that you'll submit flawless writing. Upload your document to correct all your mistakes.

Acknowledgements, table of contents, list of figures and tables, list of abbreviations, introduction, literature review / theoretical framework, methodology, reference list.

The very first page of your document contains your dissertation’s title, your name, department, institution, degree program, and submission date. Sometimes it also includes your student number, your supervisor’s name, and the university’s logo. Many programs have strict requirements for formatting the dissertation title page .

The title page is often used as cover when printing and binding your dissertation .

Prevent plagiarism, run a free check.

The acknowledgements section is usually optional, and gives space for you to thank everyone who helped you in writing your dissertation. This might include your supervisors, participants in your research, and friends or family who supported you.

The abstract is a short summary of your dissertation, usually about 150-300 words long. You should write it at the very end, when you’ve completed the rest of the dissertation. In the abstract, make sure to:

State the main topic and aims of your research
Describe the methods you used
Summarise the main results
State your conclusions

Although the abstract is very short, it’s the first part (and sometimes the only part) of your dissertation that people will read, so it’s important that you get it right. If you’re struggling to write a strong abstract, read our guide on how to write an abstract .

In the table of contents, list all of your chapters and subheadings and their page numbers. The dissertation contents page gives the reader an overview of your structure and helps easily navigate the document.

All parts of your dissertation should be included in the table of contents, including the appendices. You can generate a table of contents automatically in Word.

If you have used a lot of tables and figures in your dissertation, you should itemise them in a numbered list . You can automatically generate this list using the Insert Caption feature in Word.

If you have used a lot of abbreviations in your dissertation, you can include them in an alphabetised list of abbreviations so that the reader can easily look up their meanings.

If you have used a lot of highly specialised terms that will not be familiar to your reader, it might be a good idea to include a glossary . List the terms alphabetically and explain each term with a brief description or definition.

In the introduction, you set up your dissertation’s topic, purpose, and relevance, and tell the reader what to expect in the rest of the dissertation. The introduction should:

Establish your research topic , giving necessary background information to contextualise your work
Narrow down the focus and define the scope of the research
Discuss the state of existing research on the topic, showing your work’s relevance to a broader problem or debate
Clearly state your objectives and research questions , and indicate how you will answer them
Give an overview of your dissertation’s structure

Everything in the introduction should be clear, engaging, and relevant to your research. By the end, the reader should understand the what , why and how of your research. Not sure how? Read our guide on how to write a dissertation introduction .

Before you start on your research, you should have conducted a literature review to gain a thorough understanding of the academic work that already exists on your topic. This means:

Collecting sources (e.g. books and journal articles) and selecting the most relevant ones
Critically evaluating and analysing each source
Drawing connections between them (e.g. themes, patterns, conflicts, gaps) to make an overall point

In the dissertation literature review chapter or section, you shouldn’t just summarise existing studies, but develop a coherent structure and argument that leads to a clear basis or justification for your own research. For example, it might aim to show how your research:

Addresses a gap in the literature
Takes a new theoretical or methodological approach to the topic
Proposes a solution to an unresolved problem
Advances a theoretical debate
Builds on and strengthens existing knowledge with new data

The literature review often becomes the basis for a theoretical framework , in which you define and analyse the key theories, concepts and models that frame your research. In this section you can answer descriptive research questions about the relationship between concepts or variables.

The methodology chapter or section describes how you conducted your research, allowing your reader to assess its validity. You should generally include:

The overall approach and type of research (e.g. qualitative, quantitative, experimental, ethnographic)
Your methods of collecting data (e.g. interviews, surveys, archives)
Details of where, when, and with whom the research took place
Your methods of analysing data (e.g. statistical analysis, discourse analysis)
Tools and materials you used (e.g. computer programs, lab equipment)
A discussion of any obstacles you faced in conducting the research and how you overcame them
An evaluation or justification of your methods

Your aim in the methodology is to accurately report what you did, as well as convincing the reader that this was the best approach to answering your research questions or objectives.

Next, you report the results of your research . You can structure this section around sub-questions, hypotheses, or topics. Only report results that are relevant to your objectives and research questions. In some disciplines, the results section is strictly separated from the discussion, while in others the two are combined.

For example, for qualitative methods like in-depth interviews, the presentation of the data will often be woven together with discussion and analysis, while in quantitative and experimental research, the results should be presented separately before you discuss their meaning. If you’re unsure, consult with your supervisor and look at sample dissertations to find out the best structure for your research.

In the results section it can often be helpful to include tables, graphs and charts. Think carefully about how best to present your data, and don’t include tables or figures that just repeat what you have written – they should provide extra information or usefully visualise the results in a way that adds value to your text.

Full versions of your data (such as interview transcripts) can be included as an appendix .

The discussion is where you explore the meaning and implications of your results in relation to your research questions. Here you should interpret the results in detail, discussing whether they met your expectations and how well they fit with the framework that you built in earlier chapters. If any of the results were unexpected, offer explanations for why this might be. It’s a good idea to consider alternative interpretations of your data and discuss any limitations that might have influenced the results.

The discussion should reference other scholarly work to show how your results fit with existing knowledge. You can also make recommendations for future research or practical action.

The dissertation conclusion should concisely answer the main research question, leaving the reader with a clear understanding of your central argument. Wrap up your dissertation with a final reflection on what you did and how you did it. The conclusion often also includes recommendations for research or practice.

In this section, it’s important to show how your findings contribute to knowledge in the field and why your research matters. What have you added to what was already known?

You must include full details of all sources that you have cited in a reference list (sometimes also called a works cited list or bibliography). It’s important to follow a consistent reference style . Each style has strict and specific requirements for how to format your sources in the reference list.

The most common styles used in UK universities are Harvard referencing and Vancouver referencing . Your department will often specify which referencing style you should use – for example, psychology students tend to use APA style , humanities students often use MHRA , and law students always use OSCOLA . M ake sure to check the requirements, and ask your supervisor if you’re unsure.

To save time creating the reference list and make sure your citations are correctly and consistently formatted, you can use our free APA Citation Generator .

Your dissertation itself should contain only essential information that directly contributes to answering your research question. Documents you have used that do not fit into the main body of your dissertation (such as interview transcripts, survey questions or tables with full figures) can be added as appendices .

Note making for dissertations: First steps into writing

Note making (as opposed to note taking) is an active practice of recording relevant parts of reading for your research as well as your reflections and critiques of those studies. Note making, therefore, is a pre-writing exercise that helps you to organise your thoughts prior to writing. In this module, we will cover:

The difference between note taking and note making
Seven tips for good note making
Strategies for structuring your notes and asking critical questions
Different styles of note making

To complete this section, you will need:

Approximately 20-30 minutes.
Access to the internet. All the resources used here are available freely.
Some equipment for jotting down your thoughts, a pen and paper will do, or your phone or another electronic device.

Note taking v note making

When you think about note taking, what comes to mind? Perhaps trying to record everything said in a lecture? Perhaps trying to write down everything included in readings required for a course?

Note taking is a passive process. When you take notes, you are often trying to record everything that you are reading or listening to. However, you may have noticed that this takes a lot of effort and often results in too many notes to be useful.
Note making , on the other hand, is an active practice, based on the needs and priorities of your project. Note making is an opportunity for you to ask critical questions of your readings and to synthesise ideas as they pertain to your research questions. Making notes is a pre-writing exercise that develops your academic voice and makes writing significantly easier.

Seven tips for effective note making

Question prompts for strategic note making

You might consider structuring your notes to answer the following questions. Remember that note making is based on your needs, so not all of these questions will apply in all cases. You might try answering these questions using the note making styles discussed in the next section.

Question prompts for strategic note making
Background question prompts
Critical question prompts
Synthesis question prompts

Answer these six questions to frame your reading and provide context.

What is the context in which the text was written? What came before it? Are there competing ideas?
Who is the intended audience?
What is the author’s purpose?
How is the writing organised?
What are the author’s methods?
What is the author’s key argument and conclusions?

Answer these six questions to determine your critical perspectivess and develop your academic voice.

What are the most interesting/compelling ideas (to you) in this study?
Why do you find them interesting? How do they relate to your study?
What questions do you have about the study?
What could it cover better? How could it have defended its research better?
What are the implications of the study? (Look not just to the conclusions but also to definitions and models)
Are there any gaps in the study? (Look not just at conclusions but definitions, literature review, methodology)

Answer these five questions to compare aspects of various studies (such as for a literature review.

What are the similarities and differences in the literature?
Critically analyse the strengths, limitations, debates and themes that emerg from the literature.
What would you suggest for future research or practice?
Where are the gaps in the literature? What is missing? Why?
What new questions should be asked in this area of study?

How to Write a Thesis or Dissertation Introduction

Published on September 7, 2022 by Tegan George and Shona McCombes. Revised on November 21, 2023.

The introduction is the first section of your thesis or dissertation , appearing right after the table of contents . Your introduction draws your reader in, setting the stage for your research with a clear focus, purpose, and direction on a relevant topic .

Your introduction should include:

Your topic, in context: what does your reader need to know to understand your thesis dissertation?
Your focus and scope: what specific aspect of the topic will you address?
The relevance of your research: how does your work fit into existing studies on your topic?
Your questions and objectives: what does your research aim to find out, and how?
An overview of your structure: what does each section contribute to the overall aim?

Although your introduction kicks off your dissertation, it doesn’t have to be the first thing you write — in fact, it’s often one of the very last parts to be completed (just before your abstract ).

It’s a good idea to write a rough draft of your introduction as you begin your research, to help guide you. If you wrote a research proposal , consider using this as a template, as it contains many of the same elements. However, be sure to revise your introduction throughout the writing process, making sure it matches the content of your ensuing sections.

Begin by introducing your dissertation topic and giving any necessary background information. It’s important to contextualize your research and generate interest. Aim to show why your topic is timely or important. You may want to mention a relevant news item, academic debate, or practical problem.

After a brief introduction to your general area of interest, narrow your focus and define the scope of your research.

You can narrow this down in many ways, such as by:

Geographical area
Time period
Demographics or communities
Themes or aspects of the topic

It’s essential to share your motivation for doing this research, as well as how it relates to existing work on your topic. Further, you should also mention what new insights you expect it will contribute.

Start by giving a brief overview of the current state of research. You should definitely cite the most relevant literature, but remember that you will conduct a more in-depth survey of relevant sources in the literature review section, so there’s no need to go too in-depth in the introduction.

Depending on your field, the importance of your research might focus on its practical application (e.g., in policy or management) or on advancing scholarly understanding of the topic (e.g., by developing theories or adding new empirical data). In many cases, it will do both.

Ultimately, your introduction should explain how your thesis or dissertation:

Helps solve a practical or theoretical problem
Addresses a gap in the literature
Builds on existing research
Proposes a new understanding of your topic

Prevent plagiarism. Run a free check.

Perhaps the most important part of your introduction is your questions and objectives, as it sets up the expectations for the rest of your thesis or dissertation. How you formulate your research questions and research objectives will depend on your discipline, topic, and focus, but you should always clearly state the central aim of your research.

If your research aims to test hypotheses , you can formulate them here. Your introduction is also a good place for a conceptual framework that suggests relationships between variables .

Conduct surveys to collect data on students’ levels of knowledge, understanding, and positive/negative perceptions of government policy.
Determine whether attitudes to climate policy are associated with variables such as age, gender, region, and social class.
Conduct interviews to gain qualitative insights into students’ perspectives and actions in relation to climate policy.

To help guide your reader, end your introduction with an outline of the structure of the thesis or dissertation to follow. Share a brief summary of each chapter, clearly showing how each contributes to your central aims. However, be careful to keep this overview concise: 1-2 sentences should be enough.

I. Introduction

Human language consists of a set of vowels and consonants which are combined to form words. During the speech production process, thoughts are converted into spoken utterances to convey a message. The appropriate words and their meanings are selected in the mental lexicon (Dell & Burger, 1997). This pre-verbal message is then grammatically coded, during which a syntactic representation of the utterance is built.

Speech, language, and voice disorders affect the vocal cords, nerves, muscles, and brain structures, which result in a distorted language reception or speech production (Sataloff & Hawkshaw, 2014). The symptoms vary from adding superfluous words and taking pauses to hoarseness of the voice, depending on the type of disorder (Dodd, 2005). However, distortions of the speech may also occur as a result of a disease that seems unrelated to speech, such as multiple sclerosis or chronic obstructive pulmonary disease.

This study aims to determine which acoustic parameters are suitable for the automatic detection of exacerbations in patients suffering from chronic obstructive pulmonary disease (COPD) by investigating which aspects of speech differ between COPD patients and healthy speakers and which aspects differ between COPD patients in exacerbation and stable COPD patients.

The introduction of a research paper includes several key elements:

A hook to catch the reader’s interest
Relevant background on the topic
Details of your research problem

and your problem statement

A thesis statement or research question
Sometimes an overview of the paper

Don’t feel that you have to write the introduction first. The introduction is often one of the last parts of the research paper you’ll write, along with the conclusion.

This is because it can be easier to introduce your paper once you’ve already written the body ; you may not have the clearest idea of your arguments until you’ve written them, and things can change during the writing process .

Research objectives describe what you intend your research project to accomplish.

They summarize the approach and purpose of the project and help to focus your research.

Your objectives should appear in the introduction of your research paper , at the end of your problem statement .

Scope of research is determined at the beginning of your research process , prior to the data collection stage. Sometimes called “scope of study,” your scope delineates what will and will not be covered in your project. It helps you focus your work and your time, ensuring that you’ll be able to achieve your goals and outcomes.

Defining a scope can be very useful in any research project, from a research proposal to a thesis or dissertation . A scope is needed for all types of research: quantitative , qualitative , and mixed methods .

To define your scope of research, consider the following:

Budget constraints or any specifics of grant funding
Your proposed timeline and duration
Specifics about your population of study, your proposed sample size , and the research methodology you’ll pursue
Any inclusion and exclusion criteria
Any anticipated control , extraneous , or confounding variables that could bias your research if not accounted for properly.
