research paper chapter 5 parts

Research Guide

Chapter 5 sections of a paper.

Now that you have identified your research question, have compiled the data you need, and have a clear argument and roadmap, it is time for you to write. In this Module, I will briefly explain how to develop different sections of your research paper. I devote a different chapter to the empirical section. Please take into account that these are guidelines to follow in the different section, but you need to adapt them to the specific context of your paper.

5.1 The Abstract

The abstract of a research paper contains the most critical aspects of the paper: your research question, the context (country/population/subjects and period) analyzed, the findings, and the main conclusion. You have about 250 characters to attract the attention of the readers. Many times (in fact, most of the time), readers will only read the abstract. You need to “sell” your argument and entice them to continue reading. Thus, abstracts require good and direct writing. Use journalistic style. Go straight to the point.

There are two ways in which an abstract can start:

By introducing what motivates the research question. This is relevant when some context may be needed. When there is ‘something superior’ motivating your project. Use this strategy with care, as you may confuse the reader who may have a hard time understanding your research question.

By introducing your research question. This is the best way to attract the attention of your readers, as they can understand the main objective of the paper from the beginning. When the question is clear and straightforward this is the best method to follow.

Regardless of the path you follow, make sure that the abstract only includes short sentences written in active voice and present tense. Remember: Readers are very impatient. They will only skim the papers. You should make it simple for readers to find all the necessary information.

5.2 The Introduction

The introduction represents the most important section of your research paper. Whereas your title and abstract guide the readers towards the paper, the introduction should convince them to stay and read the rest of it. This section represents your opportunity to state your research question and link it to the bigger issue (why does your research matter?), how will you respond it (your empirical methods and the theory behind), your findings, and your contribution to the literature on that issue.

I reviewed the “Introduction Formulas” guidelines by Keith Head , David Evans and Jessica B. Hoel and compiled their ideas in this document, based on what my I have seen is used in papers in political economy, and development economics.

This is not a set of rules, as papers may differ depending on the methods and specific characteristics of the field, but it can work as a guideline. An important takeaway is that the introduction will be the section that deserves most of the attention in your paper. You can write it first, but you need to go back to it as you make progress in the rest of teh paper. Keith Head puts it excellent by saying that this exercise (going back and forth) is mostly useful to remind you what are you doing in the paper and why.

5.2.1 Outline

What are the sections generally included in well-written introductions? According to the analysis of what different authors suggest, a well-written introduction includes the following sections:

• Hook: Motivation, puzzle. (1-2 paragraphs)
• Research Question: What is the paper doing? (1 paragraph)
• Antecedents: (optional) How your paper is linked to the bigger issue. Theory. (1-2 paragraphs)
• Empirical approach: Method X, country Y, dataset Z. (1-2 paragraphs)
• Detailed results: Don’t make the readers wait. (2-3 paragraphs)
• Mechanisms, robustness and limitations: (optional) Your results are valid and important (1 paragraph)
• Value added: Why is your paper important? How is it contributing to the field? (1-3 paragraphs)
• Roadmap A convention (1 paragraph)

Now, let’s describe the different sections with more detail.

5.2.1.1 1. The Hook

Your first paragraph(s) should attract the attention of the readers, showing them why your research topic is important. Some attributes here are:

• Big issue, specific angle: This is the big problem, here is this aspect of the problem (that your research tackles)
• Big puzzle: There is no single explanation of the problem (you will address that)
• Major policy implemented: Here is the issue and the policy implemented (you will test if if worked)
• Controversial debate: some argue X, others argue Y

5.2.1.2 2. Research Question

After the issue has been introduced, you need to clearly state your research question; tell the reader what does the paper researches. Some words that may work here are:

• I (We) focus on
• This paper asks whether
• In this paper,
• Given the gaps in knoweldge, this paper
• This paper investigates

5.2.1.3 3. Antecedents (Optional section)

I included this section as optional as it is not always included, but it may help to center the paper in the literature on the field.

However, an important warning needs to be placed here. Remember that the introduction is limited and you need to use it to highlight your work and not someone else’s. So, when the section is included, it is important to:

• Avoid discussing paper that are not part of the larger narrative that surrounds your work
• Use it to notice the gaps that exist in the current literature and that your paper is covering

In this section, you may also want to include a description of theoretical framework of your paper and/or a short description of a story example that frames your work.

5.2.1.4 4. Empirical Approach

One of the most important sections of the paper, particularly if you are trying to infer causality. Here, you need to explain how you are going to answer the research question you introduced earlier. This section of the introduction needs to be succint but clear and indicate your methodology, case selection, and the data used.

5.2.1.5 5. Overview of the Results

Let’s be honest. A large proportion of the readers will not go over the whole article. Readers need to understand what you’re doing, how and what did you obtain in the (brief) time they will allocate to read your paper (some eager readers may go back to some sections of the paper). So, you want to introduce your results early on (another reason you may want to go back to the introduction multiple times). Highlight the results that are more interesting and link them to the context.

According to David Evans , some authors prefer to alternate between the introduction of one of the empirical strategies, to those results, and then they introduce another empirical strategy and the results. This strategy may be useful if different empirical methodologies are used.

5.2.1.6 6. Mechanisms, Robustness and Limitations (Optional Section)

If you have some ideas about what drives your results (the mechanisms involved), you may want to indicate that here. Some of the current critiques towards economics (and probably social sciences in general) has been the strong focus on establishing causation, with little regard to the context surrounding this (if you want to hear more, there is this thread from Dani Rodrick ). Agency matters and if the paper can say something about this (sometimes this goes beyond our research), you should indicate it in the introduction.

You may also want to briefly indicate how your results are valid after trying different specifications or sources of data (this is called Robustness checks). But you also want to be honest about the limitations of your research. But here, do not diminish the importance of your project. After you indicate the limitations, finish the paragraph restating the importance of your findings.

5.2.1.7 7. Value Added

A very important section in the introduction, these paragraphs help readers (and reviewers) to show why is your work important. What are the specific contributions of your paper?

This section is different from section 3 in that it points out the detailed additions you are making to the field with your research. Both sections can be connected if that fits your paper, but it is quite important that you keep the focus on the contributions of your paper, even if you discuss some literature connected to it, but always with the focus of showing what your paper adds. References (literature review) should come after in the paper.

5.2.1.8 8. Roadmap

A convention for the papers, this section needs to be kept short and outline the organization of the paper. To make it more useful, you can highlight some details that might be important in certain sections. But you want to keep this section succint (most readers skip this paragraph altogether).

5.2.2 In summary

The introduction of your paper will play a huge role in defining the future of your paper. Do not waste this opportunity and use it as well as your North Star guiding your path throughout the rest of the paper.

5.3 Context (Literature Review)

Do you need a literature review section?

5.4 Conclusion

Thesis Writing: What to Write in Chapter 5

Table of contents, introduction.

This article tells what a budding researcher must include in Chapter 5-the Summary. It also includes the tense of the verb and the semantic markers, which are predominantly used in writing the summary, conclusions, and recommendations.

For others, writing Chapter 5 is the easiest part of thesis writing, but there are groups of students who would like to know more about it. If you are one of them, this article on how to write chapter 5 of your thesis is purposely written for you.

What to Write in Chapter 5

1. write the summary.

If you notice, all the parts mentioned above are already included in your Chapters 1- 4. So, the challenge is on how you are going to write and present it in Chapter 5 briefly.

Then, write sentences in  simple past  and always use  passive voice  construction rather than the active voice. You must also be familiar with the different semantic markers.

When I was enrolled in Academic Writing in my master’s degree, I learned that there are semantic markers which can be used in order not to repeat the same words or phrases such as  additionally, also, further, in addition to, moreover, contrary to, with regard to, as regards, however, finally, during the past ___ years, from 1996 to 2006, after 10 years, as shown in, as presented in, consequently, nevertheless, in fact, on the other hand, subsequently and nonetheless.

Next, you may use the following guide questions to check that you have not missed anything in writing the summary:

Finally, organize the summary of the results of your study according to the way the questions are sequenced in the statement of the problem.

2. Write the Conclusion or Conclusions

Once you have written the summary in Chapter 5, draw out a conclusion from each finding or result. It can be done per question, or you may arrange the questions per topic or sub-topic if there is any. But if your research is quantitative, answer the research question directly and tell if the hypothesis is rejected or accepted based on the findings.

As to grammar, make sure that you use the  present tense of the verb  because it comprises a general statement of the theory or the principle newly derived from the present study. So, don’t be confused because, in your summary, you use past tense, while in conclusion; you use the present tense.

3. Write the Recommendations

The recommendations must contain practical suggestions that will improve the situation or solve the problem investigated in the study.

First, it must be logical, specific, attainable, and relevant. Second, it should be addressed to persons, organizations, or agencies directly concerned with the issues or to those who can immediately implement the recommended solutions. Third, present another topic which is very relevant to the present study that can be further investigated by future researchers.

But never recommend anything that is not part of your study or not being mentioned in your findings.

Recommend nothing that is not part of your research or not being mentioned in your findings.

Parts of the Research Paper Papers should have a beginning, a middle, and an end. Your introductory paragraph should grab the reader's attention, state your main idea, and indicate how you will support it. The body of the paper should expand on what you have stated in the introduction. Finally, the conclusion restates the paper's thesis and should explain what you have learned, giving a wrap up of your main ideas.

1. The Title The title should be specific and indicate the theme of the research and what ideas it addresses. Use keywords that help explain your paper's topic to the reader. Try to avoid abbreviations and jargon. Think about keywords that people would use to search for your paper and include them in your title.

2. The Abstract The abstract is used by readers to get a quick overview of your paper. Typically, they are about 200 words in length (120 words minimum to  250 words maximum). The abstract should introduce the topic and thesis, and should provide a general statement about what you have found in your research. The abstract allows you to mention each major aspect of your topic and helps readers decide whether they want to read the rest of the paper. Because it is a summary of the entire research paper, it is often written last. 

3. The Introduction The introduction should be designed to attract the reader's attention and explain the focus of the research. You will introduce your overview of the topic,  your main points of information, and why this subject is important. You can introduce the current understanding and background information about the topic. Toward the end of the introduction, you add your thesis statement, and explain how you will provide information to support your research questions. This provides the purpose and focus for the rest of the paper.

4. Thesis Statement Most papers will have a thesis statement or main idea and supporting facts/ideas/arguments. State your main idea (something of interest or something to be proven or argued for or against) as your thesis statement, and then provide your supporting facts and arguments. A thesis statement is a declarative sentence that asserts the position a paper will be taking. It also points toward the paper's development. This statement should be both specific and arguable. Generally, the thesis statement will be placed at the end of the first paragraph of your paper. The remainder of your paper will support this thesis.

Students often learn to write a thesis as a first step in the writing process, but often, after research, a writer's viewpoint may change. Therefore a thesis statement may be one of the final steps in writing.

5. The Literature Review The purpose of the literature review is to describe past important research and how it specifically relates to the research thesis. It should be a synthesis of the previous literature and the new idea being researched. The review should examine the major theories related to the topic to date and their contributors. It should include all relevant findings from credible sources, such as academic books and peer-reviewed journal articles. You will want  to:

• Explain how the literature helps the researcher understand the topic.
• Try to show connections and any disparities between the literature.
• Identify new ways to interpret prior research.
• Reveal any gaps that exist in the literature.

6. The Discussion ​The purpose of the discussion is to interpret and describe what you have learned from your research. Make the reader understand why your topic is important. The discussion should always demonstrate what you have learned from your readings (and viewings) and how that learning has made the topic evolve, especially from the short description of main points in the introduction.Explain any new understanding or insights you have had after reading your articles and/or books. Paragraphs should use transitioning sentences to develop how one paragraph idea leads to the next. The discussion will always connect to the introduction, your thesis statement, and the literature you reviewed, but it does not simply repeat or rearrange the introduction. You want to: 

• Demonstrate critical thinking, not just reporting back facts that you gathered.
• If possible, tell how the topic has evolved over the past and give it's implications for the future.
• Fully explain your main ideas with supporting information.
• Explain why your thesis is correct giving arguments to counter points.

7. The Conclusion A concluding paragraph is a brief summary of your main ideas and restates the paper's main thesis, giving the reader the sense that the stated goal of the paper has been accomplished. What have you learned by doing this research that you didn't know before? What conclusions have you drawn? You may also want to suggest further areas of study, improvement of research possibilities, etc. to demonstrate your critical thinking regarding your research.

How to Write Recommendations in Research | Examples & Tips

Published on September 15, 2022 by Tegan George . Revised on July 18, 2023.

Recommendations in research are a crucial component of your discussion section and the conclusion of your thesis , dissertation , or research paper .

As you conduct your research and analyze the data you collected , perhaps there are ideas or results that don’t quite fit the scope of your research topic. Or, maybe your results suggest that there are further implications of your results or the causal relationships between previously-studied variables than covered in extant research.

What should recommendations look like, building your research recommendation, how should your recommendations be written, recommendation in research example, other interesting articles, frequently asked questions about recommendations.

Recommendations for future research should be:

• Concrete and specific
• Supported with a clear rationale
• Directly connected to your research

Overall, strive to highlight ways other researchers can reproduce or replicate your results to draw further conclusions, and suggest different directions that future research can take, if applicable.

Relatedly, when making these recommendations, avoid:

• Undermining your own work, but rather offer suggestions on how future studies can build upon it
• Suggesting recommendations actually needed to complete your argument, but rather ensure that your research stands alone on its own merits
• Using recommendations as a place for self-criticism, but rather as a natural extension point for your work

There are many different ways to frame recommendations, but the easiest is perhaps to follow the formula of research question   conclusion  recommendation. Here’s an example.

Conclusion An important condition for controlling many social skills is mastering language. If children have a better command of language, they can express themselves better and are better able to understand their peers. Opportunities to practice social skills are thus dependent on the development of language skills.

As a rule of thumb, try to limit yourself to only the most relevant future recommendations: ones that stem directly from your work. While you can have multiple recommendations for each research conclusion, it is also acceptable to have one recommendation that is connected to more than one conclusion.

These recommendations should be targeted at your audience, specifically toward peers or colleagues in your field that work on similar subjects to your paper or dissertation topic . They can flow directly from any limitations you found while conducting your work, offering concrete and actionable possibilities for how future research can build on anything that your own work was unable to address at the time of your writing.

While it may be tempting to present new arguments or evidence in your thesis or disseration conclusion , especially if you have a particularly striking argument you’d like to finish your analysis with, you shouldn’t. Theses and dissertations follow a more formal structure than this.

All your findings and arguments should be presented in the body of the text (more specifically in the discussion section and results section .) The conclusion is meant to summarize and reflect on the evidence and arguments you have already presented, not introduce new ones.

The conclusion of your thesis or dissertation should include the following:

• A restatement of your research question
• A summary of your key arguments and/or results
• A short discussion of the implications of your research

For a stronger dissertation conclusion , avoid including:

• Important evidence or analysis that wasn’t mentioned in the discussion section and results section
• Generic concluding phrases (e.g. “In conclusion …”)
• Weak statements that undermine your argument (e.g., “There are good points on both sides of this issue.”)

Your conclusion should leave the reader with a strong, decisive impression of your work.

In a thesis or dissertation, the discussion is an in-depth exploration of the results, going into detail about the meaning of your findings and citing relevant sources to put them in context.

The conclusion is more shorter and more general: it concisely answers your main research question and makes recommendations based on your overall findings.

You may have finished the best research project on earth but, if you do not write an interesting and well laid out paper, then nobody is going to take your findings seriously.

The main thing to remember with any research paper is that it is based on an hourglass structure. It begins with general information and undertaking a literature review , and becomes more specific as you nail down a research problem and hypothesis .

Finally, it again becomes more general as you try to apply your findings to the world at general.

Whilst there are a few differences between the various disciplines, with some fields placing more emphasis on certain parts than others, there is a basic underlying structure.

These steps are the building blocks of constructing a good research paper. This section outline how to lay out the parts of a research paper, including the various experimental methods and designs.

The principles for literature review and essays of all types follow the same basic principles.

Reference List

For many students, writing the introduction is the first part of the process, setting down the direction of the paper and laying out exactly what the research paper is trying to achieve.

For others, the introduction is the last thing written, acting as a quick summary of the paper. As long as you have planned a good structure for the parts of a research paper, both approaches are acceptable and it is a matter of preference.

A good introduction generally consists of three distinct parts:

• You should first give a general presentation of the research problem.
• You should then lay out exactly what you are trying to achieve with this particular research project.
• You should then state your own position.

Ideally, you should try to give each section its own paragraph, but this will vary given the overall length of the paper.

1) General Presentation

Look at the benefits to be gained by the research or why the problem has not been solved yet. Perhaps nobody has thought about it, or maybe previous research threw up some interesting leads that the previous researchers did not follow up.

Another researcher may have uncovered some interesting trends, but did not manage to reach the significance level , due to experimental error or small sample sizes .

2) Purpose of the Paper

The research problem does not have to be a statement, but must at least imply what you are trying to find.

Many writers prefer to place the thesis statement or hypothesis here, which is perfectly acceptable, but most include it in the last sentences of the introduction, to give the reader a fuller picture.

3) A Statement of Intent From the Writer

The idea is that somebody will be able to gain an overall view of the paper without needing to read the whole thing. Literature reviews are time-consuming enough, so give the reader a concise idea of your intention before they commit to wading through pages of background.

In this section, you look to give a context to the research, including any relevant information learned during your literature review. You are also trying to explain why you chose this area of research, attempting to highlight why it is necessary. The second part should state the purpose of the experiment and should include the research problem. The third part should give the reader a quick summary of the form that the parts of the research paper is going to take and should include a condensed version of the discussion.

This should be the easiest part of the paper to write, as it is a run-down of the exact design and methodology used to perform the research. Obviously, the exact methodology varies depending upon the exact field and type of experiment .

There is a big methodological difference between the apparatus based research of the physical sciences and the methods and observation methods of social sciences. However, the key is to ensure that another researcher would be able to replicate the experiment to match yours as closely as possible, but still keeping the section concise.

You can assume that anybody reading your paper is familiar with the basic methods, so try not to explain every last detail. For example, an organic chemist or biochemist will be familiar with chromatography, so you only need to highlight the type of equipment used rather than explaining the whole process in detail.

In the case of a survey , if you have too many questions to cover in the method, you can always include a copy of the questionnaire in the appendix . In this case, make sure that you refer to it.

This is probably the most variable part of any research paper, and depends on the results and aims of the experiment.

For quantitative research , it is a presentation of the numerical results and data, whereas for qualitative research it should be a broader discussion of trends, without going into too much detail.

For research generating a lot of results , then it is better to include tables or graphs of the analyzed data and leave the raw data in the appendix, so that a researcher can follow up and check your calculations.

A commentary is essential to linking the results together, rather than just displaying isolated and unconnected charts and figures.

It can be quite difficult to find a good balance between the results and the discussion section, because some findings, especially in a quantitative or descriptive experiment , will fall into a grey area. Try to avoid repeating yourself too often.

It is best to try to find a middle path, where you give a general overview of the data and then expand on it in the discussion - you should try to keep your own opinions and interpretations out of the results section, saving that for the discussion later on.

This is where you elaborate on your findings, and explain what you found, adding your own personal interpretations.

Ideally, you should link the discussion back to the introduction, addressing each point individually.

It’s important to make sure that every piece of information in your discussion is directly related to the thesis statement , or you risk cluttering your findings. In keeping with the hourglass principle, you can expand on the topic later in the conclusion .

The conclusion is where you build on your discussion and try to relate your findings to other research and to the world at large.

In a short research paper, it may be a paragraph or two, or even a few lines.

In a dissertation, it may well be the most important part of the entire paper - not only does it describe the results and discussion in detail, it emphasizes the importance of the results in the field, and ties it in with the previous research.

Some research papers require a recommendations section, postulating the further directions of the research, as well as highlighting how any flaws affected the results. In this case, you should suggest any improvements that could be made to the research design .

No paper is complete without a reference list , documenting all the sources that you used for your research. This should be laid out according to APA , MLA or other specified format, allowing any interested researcher to follow up on the research.

One habit that is becoming more common, especially with online papers, is to include a reference to your own paper on the final page. Lay this out in MLA, APA and Chicago format, allowing anybody referencing your paper to copy and paste it.

Chapter 5: Conclusion, Interpretation and Discussion

Introduction.

The following chapter concludes this report. A summary of the research is presented, and findings of the study are discussed and interpreted. The significance of this research in the immediate context of El Gallo and in the field of low-income housing is examined. Recommendations for further research end the chapter.

The scope of the following conclusions is limited to the context and historical characteristics of El Gallo. Thus, applied to other situations, these conclusions may yield incorrect assumptions. Still, these conclusions are relevant to the process of dwelling evolution in progressive development projects.

5.1 Summary of Research

This study observed the process of dwelling evolution in progressive development projects. The literature review was concentrated on the process of progressive development occurring in planned sponsored projects. It was found that, based on observations of the informal settlement process, progressive development under different contextual conditions was not questioned, and its benefits were taken for granted. Studies in the area were reduced to the period of improvement up to the time when the dwelling was physically consolidated. Longer term evaluation of progressive development projects were not found.

Research was undertaken on a 27-year-old progressive development project in Venezuela. The intention was to observe the process of dwelling evolution and the kind of housing that was being produced under progressive urban development projects on a long-term basis. The case study showed dwellings built with different initial levels of user-participation. Dwelling evolution was observed in a survey sample using parameters relevant to the case study (i.e., area increase, dwelling spatial growth and plot occupation, and changes in the functional structure).

Survey dwellings followed identifiable patterns of evolution in size, spatial structure and use-layout. Patterns were affected by aspects of the surrounding context and by aspects inherent to characteristics of the initial dwelling. Consequently, different dwelling groups showed different processes of progressive development.

5.2 Discussion and Interpretation of Findings.

As progressive developments, dwellings at El Gallo were able to adopt new and diverse roles along their whole process of evolution. In this section, relevant issues of the process of dwelling evolution observed at El Gallo are discussed. The first concerns the role of the non-permanent structure in the context of El Gallo as a sponsored progressive development project. The second comments on the process of dwelling evolution that followed the construction of the permanent structure.

In principle, non-permanent structures at El Gallo were similar to ranchos built in informal settlements. Ranchos at El Gallo served as primary shelters while more basic household priorities were met (i.e., services and infrastructure were provided, sources of income were found and generated, and even a favourable social environment was developed among neighbours). However, the majority of tin shacks were neither considerably increased nor upgraded with better materials even when they were used for long periods of time. This fact, together with the sudden change in the pace of development caused by the construction of a very complete permanent dwelling and subsequent removal of the rancho, had no connection with the gradual process of shack replacement observed in invasion settlements of Ciudad Guayana during this study (Portela, M. 1992). Neither did this process have a relationship with the system of "piecemeal construction" described by several housing researchers as characteristic of low-income dwellers.

The shanties were... housing in process of improvement. In particular the piecemeal system of building afforded great advantages to those who, like most of the poor in developing societies, have great variations in income from month to month (Peattie L. 1982:132).

Under El Gallo conditions of land security, ranchos did not show consolidation, and revealed their transient character because they were eventually substituted by permanent structures. The non-permanent structure revealed the primary household's aspiration for a minimum satisfactory habitable area. However, besides basic shelter during the initial stage, ranchos served to the purposes of capital accumulation that eventually allowed households to buy a basic unit according to official standards, or building a bigger, more complete first permanent structure. The size of ranchos reflected households' aspirations for the permanent dwelling, that is,smaller ranchos were substituted by basic units of the housing programs. Instead larger ranchos were substituted by large self-produced dwellings.

It is difficult to ascertain why ranchos were removed when they could have been kept as part of the dwelling, as in fact did a minority of households (2 cases). Is a fact that the temporary materials of ranchos contributed to their deterioration that ended with the total removal of the rancho. However, an idea that may have contributed to the demolition of the rancho was the household's adoption of the planner's belief that ranchos were a bad but necessary step on the way to obtaining permanent housing. Thus, once the permanent dwelling was built, the price households paid to gain credibility (i.e., that this stage was reached) was the demolition of the rancho itself. This interpretation can be specially true for Ciudad Guayana, where dwellings of certain quality such as those of El Gallo were seen as "casas" or houses. Instead, structures of similar quality in the hills of cities such as Caracas were still considered ranchos. In the long run, informal settlements obtained the largest benefits from this process because they gained far more official tolerance and social credibility (i.e., that shacks were actually temporary means of residence towards good-quality housing).

Those who lived in smaller ranchos improved their spatial conditions by moving to the small basic dwellings. Those who occupied bigger ranchos built bigger dwellings by themselves. Still, some households built their dwellings without going through the rancho stage. Self-produced dwellings followed the formal models either to gain the government's credibility of user commitment to build "good" government-like housing, or because households believed so. Imitation of the formal models, however, varied according to the builder's interpretation. For instance, the pattern of the detached dwelling was adopted, but often one of the side yards was reduced to a physical separation between the dwelling and the plot separation wall. More effective interpretations involved enlarging the front porch or using the central circulation axis to allow easy extension in the future.

The building approach of the permanent structure influenced the process of evolution that followed. Basic units built by the housing agencies had a compact, complete layout with higher standards of construction; however, aspects of the design, such as internal dimensions, were inadequate for household criteria, and the layout was not well adapted. Dwellings built according to provided plans and specificationshad similar problems, but households enlarged spaces and modified layouts when they were building the units. The level of construction standards was also reduced since the lateral façades of some dwellings were unfinished. Dwellings built totally by self-help means were the largest permanent structures. Aspects of the design of the first permanent structure allowed easy extension of the dwelling towards open areas of the plot. More user participation was reflected in straight-forward processes of evolution without internal modifications, and fewer stages to reach the current houseform.

5.3 Significance of the Study

While this study acknowledges again the effectiveness of progressive development in the housing system, it shows how dwelling evolution in progressive development projects can have different characteristics produced by internal and external interventions. Usually, projects are designed and launched to reproduce certain desirable outcomes and meet specific expectations. However, conditions prevailing in these projects and sometimes strategies that are introduced to "improve," "speed up" or make more "efficient" the process of evolution can affect the outcome in many different ways. This study showed how contextual characteristics of El Gallo, as well as the design and level of user participation in the initial permanent dwelling, affected successive stages of progressive development. However, it is important to recognize that are other issues beyond the spatial aspects that are intrinsically related with the evolution of the dwellings and that were not included within the scope of these particular research (i.e., household's changes in income, size, and age or gender structure).

The findings at El Gallo add modestly to the body of knowledge of literature on progressive development. Progressive Urban Development Units, UMUPs , have been the main housing strategy in Ciudad Guayana these last years, and they are likely to keep being used. Simple facts such as knowing the characteristics of the additions and modifications that households make to their dwellings over time can be the basis for more assertive actions supporting or enforcing progressive development activities. Understanding the process of dwelling evolution in low-income developments would be an effective way to help the process that, in the case of Ciudad Guayana, zonings and bylaws have been unable to regulate.

5.4 Recommendations for Further Research

Long term assessments are particularly constrained by the availability and reliability of recorded data. The frequency, and often the methodology, in which censuses and surveys are made do not always suit the purposes of this kind of research. Household interviews are very important, but they may become troubled by informant's limited memories and the continuity of the household in the dwelling. Aerial documentation, if available, represents one of the most reliable sources to observe physical change. Nevertheless, a careful and detailed process of observation of aerial data becomes very time consuming. For similar studies, a first phase in which the housing diversity is identified in the aerial data according to the selected criteria, would allow to reduce the number of detailed survey samples needed, thus considerably reducing the time of data collection.

In the context of Ciudad Guayana, further studies of the non-permanent dwelling in recent UMUPs would reveal new insights into the function of these structures in progressive development projects. This would be essential especially if any kind of initial aid is to be provided. On the other hand, following the growth of progressive developments is necessary if services and infrastructure are, as they are now, the responsibility of the local government. Identifying the producers of physical evolution -- i.e., the drivers and catalysts of change -- would be an important step for further research. An interesting step within this trend could be to ascertain the extent in which other household processes -- family growth, income increase and economic stability, household aging, changes in the household composition (single- to multi- family), etc., affect the process of dwelling evolution.

In the context of low-income housing, the process of progressive development needs further understanding. As in Ciudad Guayana, progressive development is likely to be the main housing strategy for other developing countries in the near future. Local authorities would do well to follow the evolution of settlements and to identify real household needs, and the consequences of public and/or private interventions in low-income settlements. Perhaps the most important learning of this study is that the experience of El Gallo acknowledges again the dynamic participation of the low-income households under different conditions, and still leaves wide room for a positive participation for the many other actors in the evolving urban entity.

. Notes for Chapter V

1 Dodge reports that some settlers of Ciudad Guayana kept the rancho and rented it to poorer families (Dodge,C. 1968:220). This attitude has been more common in other progressive development projects. The Dandora site and services also encouraged the construction of temporary shacks while the permanent dwelling was built. However, non-permanent structures remained to be rented or used as storage areas even after the permanent dwelling was built (McCarney, P.L. 1987:90).

Chapter 5 Summary, Conclusions, Discussions, & Recommendations Applied Research Center Abraham S. Fischler School of Education Summer Conference 2012

General Information This session will address the components of Chapter 5 of the Applied Dissertation. The format and style of Chapter 5 should follow the Style Guide for the Applied Dissertationand the sixth edition of the APA manual.

Chapter 5 Purpose of Chapter 5: To provide the readers with a thorough understanding of what the results of your study mean to the research field and to professional practice.

Chapter 5 Chapter 5 allows you to summarize the findings, discuss the importance of the findings, place the research findings in the context of current literature, compare and contrast the research findings with other relevant research, identify the strengths and weaknesses of the research study, discuss the implications of the research findings, and make recommendations for future research.

Summary of Findings Restate the results presented in Chapter 4 using little or no statistical jargon. Write in a clear straightforward manner with no interpretation of the results. Use past tense. Do not include tables and figures. Identify whether the findings of your study supported the hypotheses or research questions. Present unusual findings (e.g., results that you did not expect to be significant but were, and vice versa).

Interpretation of Findings Analyze both significant findings and not significant findings. Were the results what you predicted? Why do you think the results turned out the way they did? Were there any issues related to sampling, measurement, and procedural issues, as well as confounding variables? Provide possible explanations for the results. Link the results to any theoretical framework you used to develop your research question or hypotheses.

Context of Findings Place your findings in perspective to other studies of the topic found in the reviewed literature. How are your findings similar or different from those of other studies? Based on the literature, are the findings what might have been expected? If your results differ from those of other studies, what plausible explanations can account for this?

Implications of Findings • How do the findings expand the understanding of the phenomenon under study? • Identify the implications of the findings for • Theory: Are findings consistent with current theories in the field? Are they consistent with the selected theoretical framework for your study? • Research: Does the study help advance the research methodology in the field? (e.g., understanding of new confounding variables, issues of measurement, issues of design) • Practice: Who may be interested in using these findings in a professional field? Why should they pay attention to the findings? Could the findings lead to changes in the way professionals “do” things?

Discussion on Limitations Review the potential limitations that you initially proposed in the proposal. Discuss the limitations that may have affected—one way or another—your findings. Limitations typically originate in one of two sources: the study’s design and the study’s problems during implementation. Issues of design involve decisions about sampling, assessment, procedures, and choice of research design (poor match). Some of the issues that may have arisen at the time of research implementation relate to low sample size, measurement issues, heterogeneous groups, and so forth.

Discussion on Limitations (Cont.) Think of limitations in four major areas: Internal Validity—Unless the study is a “true experiment” one cannot claim that the IV “caused” changes in the DV. External Validity—Discuss the extent to which findings can be generalized. Measurement—Discuss issues of reliability and validity of assessment instruments. Statistical Analysis—Discuss issues of power, effect size, conservative or liberal statistics, and statistical test chosen.

Discussion on Future Directions Discuss findings in light of questions or issues that suggest future research directions. Extend the study to other populations. Think of other IVs and DVs that ought to be explored in the field; also, think of how to assess those additional variables. This is the section of the paper where most researchers are allowed to dream; think of extending your study to other questions that may add to the understanding of the issues.

Structuring the Research Paper

Formal research structure.

These are the primary purposes for formal research:

enter the discourse, or conversation, of other writers and scholars in your field

learn how others in your field use primary and secondary resources

find and understand raw data and information

For the formal academic research assignment, consider an organizational pattern typically used for primary academic research.  The pattern includes the following: introduction, methods, results, discussion, and conclusions/recommendations.

Usually, research papers flow from the general to the specific and back to the general in their organization. The introduction uses a general-to-specific movement in its organization, establishing the thesis and setting the context for the conversation. The methods and results sections are more detailed and specific, providing support for the generalizations made in the introduction. The discussion section moves toward an increasingly more general discussion of the subject, leading to the conclusions and recommendations, which then generalize the conversation again.

Sections of a Formal Structure

The introduction section.

Many students will find that writing a structured  introduction  gets them started and gives them the focus needed to significantly improve their entire paper. 

Introductions usually have three parts:

presentation of the problem statement, the topic, or the research inquiry

purpose and focus of your paper

summary or overview of the writer’s position or arguments

In the first part of the introduction—the presentation of the problem or the research inquiry—state the problem or express it so that the question is implied. Then, sketch the background on the problem and review the literature on it to give your readers a context that shows them how your research inquiry fits into the conversation currently ongoing in your subject area. 

In the second part of the introduction, state your purpose and focus. Here, you may even present your actual thesis. Sometimes your purpose statement can take the place of the thesis by letting your reader know your intentions. 

The third part of the introduction, the summary or overview of the paper, briefly leads readers through the discussion, forecasting the main ideas and giving readers a blueprint for the paper. 

The following example provides a blueprint for a well-organized introduction.

Example of an Introduction

Entrepreneurial Marketing: The Critical Difference

In an article in the Harvard Business Review, John A. Welsh and Jerry F. White remind us that “a small business is not a little big business.” An entrepreneur is not a multinational conglomerate but a profit-seeking individual. To survive, he must have a different outlook and must apply different principles to his endeavors than does the president of a large or even medium-sized corporation. Not only does the scale of small and big businesses differ, but small businesses also suffer from what the Harvard Business Review article calls “resource poverty.” This is a problem and opportunity that requires an entirely different approach to marketing. Where large ad budgets are not necessary or feasible, where expensive ad production squanders limited capital, where every marketing dollar must do the work of two dollars, if not five dollars or even ten, where a person’s company, capital, and material well-being are all on the line—that is, where guerrilla marketing can save the day and secure the bottom line (Levinson, 1984, p. 9).

By reviewing the introductions to research articles in the discipline in which you are writing your research paper, you can get an idea of what is considered the norm for that discipline. Study several of these before you begin your paper so that you know what may be expected. If you are unsure of the kind of introduction your paper needs, ask your professor for more information.  The introduction is normally written in present tense.

THE METHODS SECTION

The methods section of your research paper should describe in detail what methodology and special materials if any, you used to think through or perform your research. You should include any materials you used or designed for yourself, such as questionnaires or interview questions, to generate data or information for your research paper. You want to include any methodologies that are specific to your particular field of study, such as lab procedures for a lab experiment or data-gathering instruments for field research. The methods section is usually written in the past tense.

THE RESULTS SECTION

How you present the results of your research depends on what kind of research you did, your subject matter, and your readers’ expectations. 

Quantitative information —data that can be measured—can be presented systematically and economically in tables, charts, and graphs. Quantitative information includes quantities and comparisons of sets of data. 

Qualitative information , which includes brief descriptions, explanations, or instructions, can also be presented in prose tables. This kind of descriptive or explanatory information, however, is often presented in essay-like prose or even lists.

There are specific conventions for creating tables, charts, and graphs and organizing the information they contain. In general, you should use them only when you are sure they will enlighten your readers rather than confuse them. In the accompanying explanation and discussion, always refer to the graphic by number and explain specifically what you are referring to; you can also provide a caption for the graphic. The rule of thumb for presenting a graphic is first to introduce it by name, show it, and then interpret it. The results section is usually written in the past tense.

THE DISCUSSION SECTION

Your discussion section should generalize what you have learned from your research. One way to generalize is to explain the consequences or meaning of your results and then make your points that support and refer back to the statements you made in your introduction. Your discussion should be organized so that it relates directly to your thesis. You want to avoid introducing new ideas here or discussing tangential issues not directly related to the exploration and discovery of your thesis. The discussion section, along with the introduction, is usually written in the present tense.

THE CONCLUSIONS AND RECOMMENDATIONS SECTION

Your conclusion ties your research to your thesis, binding together all the main ideas in your thinking and writing. By presenting the logical outcome of your research and thinking, your conclusion answers your research inquiry for your reader. Your conclusions should relate directly to the ideas presented in your introduction section and should not present any new ideas.

You may be asked to present your recommendations separately in your research assignment. If so, you will want to add some elements to your conclusion section. For example, you may be asked to recommend a course of action, make a prediction, propose a solution to a problem, offer a judgment, or speculate on the implications and consequences of your ideas. The conclusions and recommendations section is usually written in the present tense.

Key Takeaways

• For the formal academic research assignment, consider an organizational pattern typically used for primary academic research. 
•  The pattern includes the following: introduction, methods, results, discussion, and conclusions/recommendations.

Papers should have a beginning, a middle, and an end. Your introductory paragraph should grab the reader's attention, state your main idea and how you will support it. The body of the paper should expand on what you have stated in the introduction. Finally, the conclusion restates the paper's thesis and should explain what you have learned, giving a wrap up of your main ideas.   

1. The Title The title should be specific and indicate the theme of the research and what ideas it addresses. Use keywords that help explain your paper's topic to the reader. Try to avoid  abbreviations  and  jargon.  Think about keywords that people would use to search for your paper and include them in your title. 

2. The Abstract The abstract is used by readers to get a quick overview of your paper. Typically, they are about 200 words in length (120 words minimum to  250 words maximum). The abstract should introduce the topic and thesis, and should provide a general statement about what you have found in your research. The abstract allows you to mention each major aspect of you topic and helps readers decide whether they want to read the rest of the paper. Because it is a summary of the entire research paper, it is often written last. 

3. The Introduction The introduction should be designed to attract the reader's attention and explain the focus of the research. You will introduce your overview of the topic, your main points of information, and why this subject is important. You can introduce the current understanding and background information about the topic. Toward the end of the introduction, you add your thesis statement, and explain how you will provide information to support your research questions. This provides the purpose, focus, and structure for the rest of the paper.

4. Thesis Statement Most papers will have a thesis statement or main idea and supporting facts/ideas/arguments. State your main idea (something of interest or something to be proven or argued for or against) as your thesis statement, and then provide  supporting facts and arguments. A thesis statement is a declarative sentence that asserts the position a paper will be taking. It also points toward the paper's development. This statement should be both specific and arguable. Generally, the thesis statement will be placed at the end of the first paragraph of your paper. The remainder of your paper will support this thesis.

Students often learn to write a thesis as a first step in the writing process, but often, after research, a writers viewpoint may change. Therefore a thesis statement may be one of the final steps in writing.

5. The Literature Review The purpose of the literature review is to describe past important research and how it specifically relates to the research thesis. It should be a synthesis of the previous literature and the new idea being researched. The review should examine the major theories related to the topic to date and their contributors. It should include all relevant findings from credible sources, such as academic books and peer-reviewed journal articles. You will want  to:

• Explain how the literature helps the researcher understand the topic.
• Try to show connections and any disparities between the literature.
• Identify new ways to interpret prior research.
• Reveal any gaps that exist in the literature.

6. The Discussion ​The purpose of the discussion is to interpret and describe what you have learned from your research. Make the reader understand why your topic is important. The discussion should always demonstrate what you have learned from your readings (and viewings) and how that learning has made the topic evolve, especially from the short description of main points in the introduction. Explain any new understanding or insights you have had after reading your articles and/or books. Paragraphs should use transitioning sentences to develop how one paragraph idea leads to the next. The discussion will always connect to the introduction, your thesis statement, and the literature you reviewed, but it does not simply repeat or rearrange the introduction. You want to: 

• Demonstrate critical thinking, not just reporting back facts that you gathered.
• If possible, tell how the topic has evolved over the past and give it's implications for the future.
• Fully explain your main ideas with supporting information.
• Explain why your thesis is correct giving arguments to counter points.

​7. The Conclusion A concluding paragraph is a brief summary of your main ideas and restates the paper's main thesis, giving the reader the sense that the stated goal of the paper has been accomplished. What have you learned by doing this research that you didn't know before? What conclusions have you drawn? You may also want to suggest further areas of study, improvement of research possibilities, etc. to demonstrate your critical thinking regarding your research.

Research This: What Are the 5 Parts of a Research Paper?

Do you need to write a research paper to complete your high school coursework? Do you need help with identifying the different parts of an APA research paper?

Conducting research is a key step in widening your awareness and learning . It follows a scientific process, making it applicable to studies beyond educational institutions. It makes research and studies useful in all fields like business, public knowledge, and more.

Here, we’ll discuss the parts of a research paper, focusing on five key parts and their subparts. We also included some tips on how to write a good research paper. Continue below to learn more: 

1. Parts of a Research Paper: The Problem and Its Background 

When writing a research paper, the first thing to do is to present the problem you aim to address. Include the background of the study in this part. Discuss what drove you to conduct this research.

The background of the study also often serves as an introduction. After giving the context and purpose of your study, state the problem. Go back to this part of the research paper when writing the title and questionnaire.

The next slice of information to share is the significance of the study. What benefits does the study offer and who will it benefit? Later, when you write your recommendations, review this part.

Give the assumptions of the study. In short, think about the possible outcomes of your research. It’s a good way to communicate to the readers your desired results at the end of the research. 

Next, define the scope and limitations of the study. You add more context to the study by determining its coverage. Finally, define the terms used in the study to help readers reach a deeper understanding.

2. Review of Related Literature

Once you have a background, context, and limits, present a review of the literature. It helps to avoid casting doubt on the impartiality of your study.

Among all the parts of a research paper (APA format), this section is one of the most exhausting. During this phase, you and your fellow researchers must read a lot. It’s draining if you’re not the type who likes reading but prefers experimentation.

Your goal is to look for evidence supporting or refuting your study. Provide organized data from related literature. Categorize them under various subheadings. 

Keep in mind that this part is a combination of all studies. Avoid putting a simple list of individual summaries. Integrate the supporting data with your goals and expectations. 

Other than summarization, paraphrase and write indirect speeches. Doing these practices help avoid plagiarizing others’ content. You must have the skill and good command of language and writing to accomplish this task. 

3. Research Method and Procedures

Next in the parts of a research paper is to present the methods and procedures used in the research. Write down how you did the study as well as the research methods. Qualitative research is a good example.

Include the steps of a qualitative research procedure when writing your methods. The section must explain why the method was the best choice for the study.

Follow it with the subjects of the study. Your goal is to describe your respondents. Include important details such as who they are, their demographics, where they’re from, and more. Ensure that these details are relevant to further your study.

Put the details of the instruments used in the study under the right section. In most studies, the instrument is a questionnaire. After that, write your data-gathering procedures.

Once you have these down, discuss your statistical treatment strategy. Include your sampling method, formulas, and other treatments. If you find this part difficult, don’t hesitate to get research paper help  from professionals. 

4. Presentation, Analysis, and Interpretation of the Gathered Data

Fourth among the essential parts of a research paper is the presentation of all the gathered data. The most common strategy is to tabulate all the data from the questionnaires. Don’t forget to describe the results you found in your study.

If your study used both qualitative and quantitative tools, describe their separate results. Interpretations of the data must accompany the tables and descriptions. If you don’t include the interpretations of the data, your audience won’t know your tables’ meaning.

Before interpreting the gathered data, analyze it well. For example, you’re writing these parts of a historical research paper. Don’t stop at describing the type of procedures and/or software that you used.

You should also try to formulate a conclusion based on the data you gathered. This leads us to the next and final part of a research paper. 

5. Summary, Conclusions, and Recommendations

Next, summarize the research paper, especially the data interpretations. Scan and reread the research paper to get a good idea of its contents. Keep the focus of the paper in mind.

In the conclusion, answer the earlier-stated problems. Here, you’ll prove or disprove your hypotheses and assumptions. Finally, include recommendations for further research, like focuses, actions, and other aspects. 

Does writing a research paper seem exhausting or taxing? While it may seem that way for people who aren’t fond of writing or documenting their work, it’s essential. Students and even non-students can learn from writing research papers . 

You learn how to gather and analyze data before making assumptions. Applying this in real life makes you a person with critical thinking skills. Research also promotes curiosity, the use of multiple sources, and better reading skills.

Intelligent monitoring of tool condition is the key to ensuring workshop manufacturing efficiency, product machining quality, and accuracy, and is also an indispensable part of intelligent processing. In the face of complex and massive, multi-source heterogeneous, and low-value density machining process data, the monitoring method based on traditional machine learning is challenging to meet the development needs of intelligent manufacturing. In contrast, with its powerful data processing and automatic feature extraction capabilities, deep learning shows broad application prospects in tool condition intelligent monitoring. Given this, this paper first systematically introduces the components of tool condition intelligent monitoring framework based on deep learning. Subsequently, the basic principles, modeling process, and application status of the four most widely used deep learning models (deep belief network, stacked auto-encoder network, convolutional neural network, and recurrent neural network) in the field of tool condition monitoring are detailed, and the advantages and disadvantages of different models are comparably discussed. Finally, the challenges and prospects of the current tool condition intelligent monitoring based on deep learning are summarized.
