Dissertation style varies widely from field to field - describing an experiment in organic chemistry is obviously going to look pretty different from a study of Shakespearean plays. In general, though, there are a few key sections that any dissertation will need in order to be complete.
An abstract is a 100-500 word paragraph that summarizes your research. The structure of the abstract should mirror the structure of your paper - there should be a few sentences of introduction and background, one or two sentences of results, and two to three sentences discussing your conclusions. The abstract is the first, and often only, section potential readers will encounter, so take the time to craft this research summary carefully.
The main body of the dissertation starts with the introduction. This section provides the reader with some of the background information needed to understand your research and also provides an overview of what you've set out to accomplished. Start by exploring a broad view of the issues in your field, then narrow the focus to the particular subject you plan to address. Also make sure to be clear if there are any related topics your paper is NOT going to be covering: you can't address everything, so let the reader know what to expect up front.
Questions that should be answered in your introduction:
- Why is this topic important?
- How does the focus of your dissertation relate to larger issues in your field?
- What gaps in knowledge will your research address?
- What were your predictions/hypothesis going in?
Depending on the style of the dissertation you may also want to walk the reader through the organization of your chapters. This can be particularly important when writing in the humanities, since you'll have much more leeway in how you organize your ideas, and you want readers to know what to expect as they move through the paper.
The introduction will usually be much shorter than other parts of your paper and should be clear and concise. Stay away from jargon or other terms that require long explanations and avoid cluttering the section with citations. Instead, focus on your own words and ideas. It's often a good idea to also include one or two sentences that clearly summarize the goal of your research.
It's important to use the introduction to capture your audience's attention - when they reach the end of the introduction, readers should be convinced that the research you're doing is necessary and important.
The literature review is where you do the heavy lifting when it comes to providing background for your readers. In this section you'll use primary sources to spell out in detail the research that's already been done in your field and explain how your own effort fits within this framework. It shouldn't just be a list of sources, however. Instead, you want to use the work of others to clearly frame the prevailing theories, competing positions, and accepted methodology related to your work. There are several ways you can organize the literature review:
- Chronologically. Go through the literature chronologically if you want to provide perspective on the historical development of an issue.
- Thematically. If your dissertation is addressing several related concepts it can be useful to organize the literature review around particular theories or ideas.
- Methodological. You can also divide the literature into sections based on research methodology. This method isn't as common and is mostly used when doing a meta-analysis or when your work explicitly addresses methodological issues.
Keep in mind that this section should not be a review of all the research you've looked at over the course of your work, but should instead focus only on the documents that are specifically related to the material covered in the body of your paper.
No matter what field you're working in, your dissertation will need to tell the reader how you went about collecting data. This section should include an explanation of how you arrived at your chosen method of study (i.e., why are you using a particular type of experiment, a focus group, surveys, etc.) and how the study was designed.
For dissertations in the sciences, the methodology section will be a detailed, step-by-step description of the research process, including the equipment used, how measurements were taken, and the method of data analysis. After reading the methodology, a reader should know everything needed to accurately recreate your work.
If your dissertation is in the social sciences, the methodology needs to provide examples of questionnaires or other empirical data collection methods. You will also need to explain how the questions were developed and your reasons for choosing these particular tools.
For papers in the humanities the methodology section is usually shortened or omitted altogether. When included, it is commonly used to discuss the theoretical approach used by the author to analyze texts.
The results section is where you present the product of your work. This is not the place to analyze the data, however. Instead it should be a simple presentation of the information you collected. Data should be aggregated into tables or figures - never just present a list of raw numbers in your paper - and the result of any statistical analysis should also be included here. Again, the results section should be free from spin or interpretation; your data should be provided independent of the wider context of the paper.
For almost any dissertation the discussion will be the real meat of the paper. It's where you have the chance to provide your interpretation of the information you've collected and to make an argument in favor of your position. You want to present your conclusions and discuss in detail how your work led you to that position - there should be a direct line drawn from the information in the results section to your final conclusions. Once the conclusion is firmly stated, it's important to discuss how strong or weak it is. It can be tempting to exaggerate or overstate your conclusion in order to make the work seem important, but a good dissertation will address problems or limitations in the research.
The discussion is also the place to establish how your findings contribute to broader issues in your field. Refer back to the information provided in the introduction and literature review to demonstrate how your work fits within this larger framework. Lastly, take the time to explore new questions and avenues of research suggested by your findings. And remember, no new information should be presented in the discussion - this section should focus solely on analyzing information that you've already provided in the paper.
Questions that should be answered in your discussion:
- What conclusions can you draw from your findings?
- How do your findings relate to your chosen topic and to your field at large?
- What problems/limitations did you encounter in your study?
- What further avenues of research do your findings suggest?
Other dissertations styles
While these chapter headings will fit the requirements for many dissertations, every field will have its own requirements for how you organize your paper.
Papers in Philosophy, History, English, and other humanities disciplines require an abstract, introduction, literature review, and discussion, but generally do not require a results section. Instead, the bulk of the paper will be structured to fit your argument, and chapters within the discussion should be divided to best highlight the logical progression of your work. For example, a short dissertation might have a chapter explaining theoretical models and a chapter explaining how that model relates to a particular text. Longer dissertations might be structured as a kind of point-counterpoint, where the author raises a topic, presents an theory, offers possible objections to this theory, and refutes those competing ideas.
No matter the topic, the chapter structure should make it easy for the reader to follow the development of your argument. It can also be helpful to provide a general outline for your dissertation in the introduction so that readers will know what to expect.
Because engineering often combines real-world experimentation with conceptual modeling, dissertations in these fields may require a chapter in which the author presents a conceptual model based on his work and discusses its accuracy. This section - titled something like Theoretical Modeling - should follow the results and discussion, and the paper should end with a conclusion that ties together the practical and theoretical aspects of the work.
Social and hard sciences
Dissertation in the social and hard sciences will usually closely follow the chapter structure given above.
Remember, this is just a general outline. Depending on the length of your dissertation, these general sections will likely be broken down into several chapters. For example, if your dissertation covers multiple interconnected experiments, the methodology section might require more than one chapter. Similarly, the discussion might have separate chapters or subheadings for conclusions and further research suggestions. Also keep in mind that most schools have strict rules for dissertation structure and formatting, so before you start to write make sure you know the specific guidelines you'll need to follow.
This Study Guide addresses the task of writing a dissertation. It aims to help you to feel confident in the construction of this extended piece of writing, and to support you in its successful completion.
You may also find the following Study Guides helpful:
Sometimes writing is seen as an activity that happens after everything else:
“The research is going well, so the writing should be straightforward - I can leave it until later”.
“I know I’m not good at writing so I keep putting it off”.
“I know I’m good at writing so I can leave it to later”.
“I want to get everything sorted out in my mind before I start writing or I’ll just end up wasting my time re-writing”.
These four very different perspectives lead to the same potential problems:
regarding re-drafting as a failure or a waste of time;
ignoring the further learning and clarification of argument that usually occurs during the writing and re-writing process; and
leaving too little time for effective editing and final proofing.
The process of having to describe your study in detail, in a logical sequence of written words, will inevitably highlight where more thought is needed, and it may lead to new insight into connections, implications, rationale, relevance, and may lead to new ideas for further research.
Barras (1993:136) suggests that you ‘think of your report as part of your investigation, not as a duty to be undertaken when your work is otherwise complete’, and this Study Guide suggests that: writing is an integral part of the research process.
Getting on with the writing
The good news is that you have already started writing if you have written any of the following in relation to this study:
a research proposal;
a literature review;
a report of any pilot studies that you undertook;
an abstract for a conference;
reports for your supervisors;
a learning journal where you keep ideas as they occur to you; or
notes for a presentation you have given.
In each case the object of the writing was to communicate to yourself, your supervisors, or to others, something about your work. In writing your dissertation you will draw on some of this earlier writing to produce a longer and more comprehensive account.
Check out what is required
Before embarking on any substantial writing for your dissertation you will need to check the exact requirements regarding:
the word limit: maximum and minimum; and whether or not this includes words within tables, the abstract, the reference list, and the appendices;
which chapters are expected to be included, in which order, and what kind of material is expected in each;
the kind of content appropriate to place in the appendices rather than in the main text; and
the marking scheme or guidance.
There are some conventions that guide the structuring of dissertations in different disciplines. You should check departmental and course regulations.
Below are two structures that are commonly used.
- Title page
- Contents page(s)
- Materials and methods or Literature review
- Results or Sources and methods
- Discussion or Findings
Each section or chapter has its own particular function
The title itself is an important opportunity to tell the potential reader what your research is about. You will need it to be succinct, specific, descriptive, and representative of the research you have done. There is likely to be a required format for the title page in your discipline, so you need to check what that is.
This may be one of the shortest sections of your thesis or dissertation, but it is worthwhile taking great care to write it well. Essentially, the Abstract is a succinct summary of the research. It should be able to stand alone in representing why and how you did what you did, and what the results and implications are. It is often only one page long, and there may be a word limit to adhere to. The Abstract is an important element of the thesis, and will become a document in its own right if the thesis is registered within any database. The examiners will therefore assess your Abstract both as part of your thesis, and as a potentially independent document.
It can be best to write the Abstract last, once you are sure what exactly you are summarising. Alternatively it can be useful to write the abstract earlier on, as an aid to identifying the crucial main thread of your research, its purpose, and its findings, which could then guide the structure of the dissertation.
Attending to the very restrictive word / space limit, while at the same including all the relevant material is quite a challenge. It might be useful to look at how others have managed. It is certainly an academic exercise, but perhaps not too different from the concise explanations of your research you may have had to give to relatives and neighbours over the last few years, in terms of its brevity, accessibility, and comprehensiveness.
This is your opportunity to mention individuals who have been particularly helpful. Reading the acknowledgements in other dissertations in your field will give you an idea of the ways in which different kinds of help have been appreciated and mentioned.
Contents, and figure and table lists
The contents pages will show up the structure of the dissertation. Any imbalance in space devoted to different sections of content will become apparent. This is a useful check on whether amalgamation of sections, or creation of further sections or sub-sections is needed.
Although this is the first piece of writing the reader comes to, it is often best to leave its preparation to last as, until then, you will not be absolutely sure what you are introducing. The introduction has two main roles:
to expand the material summarised in the abstract, and
to signpost the content of the rest of the dissertation.
The literature review, or context of the study
The purpose of this chapter is to show that you are aware of where your own piece of research fits into the overall context of research in your field. To do this you need to:
describe the current state of research in your defined area;
consider whether there are any closely related areas that you also need to refer to;
identify a gap where you argue that further research is needed; and
explain how you plan to attend to that particular research gap.
This can lead logically into a clear statement of the research question(s) or problem(s) you will be addressing.
In addition to the research context, there may be other relevant contexts to present for example:
practice context; and
It can be difficult to identify the best order for sections in this chapter because the rationale for your choice of specific research question can be complicated, and there may be several inter-linked reasons why the research is needed. It is worth taking time to develop a logical structure as this will help to convince examiners of the relevance of your research, and that you understand its relevance. It will also provide you with a framework to refer back to in your discussion chapter, when you reflect on the extent to which your research has achieved what it set out to do.
Chapter(s) describing methods, sources, material etc
In these chapters a straightforward description is required of how you conducted the research. If you used particular equipment, processes, or materials, you will need to be clear and precise in how you describe them. You must give enough detail for another researcher to replicate your study.
Results / Findings
You will need to check which style of reporting is preferred in your field. For example a scientific dissertation would probably have very clear separation between the results and the discussion of those results; whereas a social science dissertation might have an overall chapter called Findings, bringing the results and their discussion together.
Decisions about style of presentation may need to be made about, for example:
whether you want to begin with an initial overview of the results, followed by the detail, or whether you move immediately into the detail of the results;
in which order you will be presenting the detailed results; and
what balance, in terms of word space, you want to achieve across the spread of results that you have.
This is where you review your own research in relation to the wider context in which it is located. You can refer back to the rationale that you gave for your research in the literature review, and discuss what your own research has added in this context. It is important to show that you appreciate the limitations of your research, and how these may affect the validity or usefulness of your findings. Given the acknowledged limitations, you can report on the implications of your findings for theory, research, and practice.
This chapter tends to be much shorter than the Discussion. It is not a mere ‘summary’ of your research, but needs to be ‘conclusions’ as to the main points that have emerged and what they mean for your field.
This section needs to be highly structured, and needs to include all of your references in the required referencing style. As you edit and rewrite your dissertation you will probably gain and lose references that you had in earlier versions. It is important therefore to check that all the references in your reference list are actually referenced within the text; and that all the references that appear in the text appear also in the reference list.
You need to check whether or not the appendices count within the word limit for your dissertation. Items that can usefully go in the appendices are those that a reader would want to see, but which would take up too much space and disrupt the flow if placed within the main text. Again, make sure you reference the Appendices within the main text where necessary.
Designing your detailed structure
If your dissertation is well-structured, easy to follow, logical, and coherent, your examiners will probably enjoy reading it, and will be able to listen to your argument without the distraction of trying to make all the links themselves.
The only way to achieve a consistent argument throughout a piece of writing is by creating some kind of plan or map of what you want to say. It can be useful to think of the research question or topic going like a strong thread throughout the dissertation: linking all the elements of the study, and giving coherence to its reporting.
Moving from doing the research to writing a comprehensive account of it is not necessarily easy. You may feel that you know everything in your head but can’t see how you can put it into words in the most useful order. It can be helpful to break the task down into smaller, more easily accomplished elements. The process of producing your writing plan could go as follows.
You could start by making a comprehensive and unstructured list of all the elements and ideas that you need to include, ranging from
chapter headings to notes about analysis, and from ideas for graphical representation to ideas for further research. Alternatively you could choose to start at stage 2.
List the main chapter headings in the order in which they will appear.
Under each chapter heading, list a series of important sub-headings. It may be that, for example, a literature review chapter needs to be split into a review of several different segments of literature. In this case each segment can have its own sub-heading, with a synthesis that brings the findings together at the end of the chapter.
Under each sub-heading, list the main content that needs to be included, creating sub-sub-headings if needed. If you began by making a long and unstructured list of content, you can now feed that into the developing structure by inserting it as bullet points under the relevant headings. You need to ensure that all the content you want to include has been allocated a place.
As you go, you can slot in ideas, references, quotes, clarifications, and conclusions as they occur to you, to make sure they are not forgotten.
Check that there is an appropriate balance between and within sections, and that the structure facilitates the logical and coherent description of the research study you have undertaken.
- Take feedback from others at this stage, before you begin to fill in the detail.
Filling in the detail
It can be a good idea to put the word limit to the back of your mind at this point, and concentrate on getting everything recorded in a document. You can always edit upwards or downwards later as necessary.
Writing as you go along
It is likely, and advisable, that you will not wait until the end of your research before starting to write it up. You may be required to produce one or more chapters for assessment part way through your research. The process described above can be used for any individual chapter you are working on. It is important to be prepared to critique and revise your own work several times. Even the early chapters submitted for assessment, and passing that assessment, may need to be revised later on. This is not a failure, but a positive sign of increased experience and skill.
Developing an argument
An important aspect running through your dissertation will be your argument for:
why this specific topic is worth researching;
why this is a good way to research it;
why this method of analysis is appropriate; and
why your interpretations and conclusions are reasonable.
You will refer to the work of others as you make your argument. This may involve critiquing the work of established leaders in the field. While it is important to be respectful in the way that you discuss others’ ideas and research, you are expected to engage directly, and even openly disagree with existing writing.
In Taylor’s (1989) book on writing in the arts and social sciences, he suggests that the following different approaches offer a range of academically legitimate ways to engage with published work.
Agree with, accede to, defend, or confirm a particular point of view.
Propose a new point of view.
Concede that an existing point of view has certain merits but that it needs to be qualified in certain important respects.
Reformulate an existing point of view or statement of it, such that the new version makes a better explanation.
Dismiss a point of view or another person’s work on account of its inadequacy, irrelevance, incoherence or by recourse to other appropriate criteria.
Reject, rebut or refute another’s argument on various reasoned grounds.
Reconcile two positions that may seem at variance by appeal to some ‘higher’ or ‘deeper’ principal.
Develop an existing point of view, perhaps by utilising it on larger or more complex datasets, or apply a theory to a new context
(Adapted from Taylor 1989:67)
It is important that you are assertive about what you are arguing, but it is unlikely that, in a dissertation project, you will be able to be definitive in closing an established academic debate. You should be open about where the gaps are in your research, and cautious about over-stating what you have found. Aim to be modest but realistic in relating your own research to the broader context.
Improving the structure and content
Once you have the dissertation in draft form it becomes easier to see where you can improve it. To make it easier to read you can use clear signposting at the beginning of chapters, and write links between sections to show how they relate to each other. Another technique to improve academic writing style is to ensure that each individual paragraph justifies its inclusion. More ideas will be presented in the Study Guide The art of editing.
You may choose to review your draft from the standpoint of a dissertation examiner, which might involve preparing a list of questions that you want to see answered, then reading through your dissertation scribbling comments, suggestions, criticisms, and ideas in the margin. If you have a marking guide then apply it to your dissertation and see if there are aspects that you can improve.
While you do this, be aware of whether you need to increase the number of words, or decrease it to reach your target. As you read you can then cross through material that appears unnecessary, and mark points that could be expanded. This will then form the basis for your next, improved, draft.
When to stop
Just as it can be difficult to begin writing, it can also be difficult to know when to stop. You may begin to feel that your dissertation will never be good enough, and that you need to revise it again and again. It may be helpful to divert your attention for a while to the finishing off activities you need to attend to:
writing the abstract and the introduction;
checking the reference list;
finalising the appendices; and
checking your contents page.
Coming back afresh to look critically at the main text may then enable you to complete it to your satisfaction. Remember the dissertation needs to demonstrate your ability to undertake and report research rather than to answer every question on a topic.
It is important to allow yourself enough time for the final checking and proof reading of the finished document.
Devote time to planning the structure of the dissertation.
Plan a structure that will enable you to present your argument effectively.
Fill in the detail, concentrating on getting everything recorded rather than sticking to the word limit at this stage.
Regard writing as part of the research process, not an after-thought.
Expect to edit and re-edit your material several times as it moves towards its final form.
Leave time to check and proofread thoroughly.
