Phd Dissertation Chapters Outline

Last month, we offered suggestions on how to prepare for your thesis defence: Decide whether you need more research results, sketch out a plan for those experiments and for writing thesis chapters, and--importantly--get your supervisor's support for that plan. Now it's time to wrap things up in the lab and start writing.

Writing a thesis is easier said than done, of course, and you have plenty of work ahead. But like any big undertaking, writing a thesis is easier if you break it down into smaller steps.

First things first

If you haven't already made a countdown plan as described in last month's column, start with that first. Then, before you start writing, make sure you and your supervisor agree on the table of contents. This might seem obvious, but we have seen too many students start working on chapters only to have those chapters tossed out later.

Cut the problem down to size

Once you've decided on a table of contents, it's time to expand it into a detailed outline. Your outline will be several pages long and consist of chapter headings, subheadings, figure and table titles, some key words, and essential comments. Your outline will keep you on track and provide you with a framework for the text. It also forces you to break up the writing into manageable pieces.

Determine the format

Your department or university may have a standard format for your thesis. If so, there's probably a standard template you should use. If not, save yourself frustration and time by copying the format from a thesis that appeals to you. Make sure the format or template is easy to use. Once you've sent your thesis to your committee for review, you may consider upgrading your layout. For now, factor the format into your plan, but don't make it your primary concern.

While we're on the subject of format, be sure to use the proper citation format for your list of references. This list can run into the hundreds, so use the approved format for citing literature from the very beginning--both in the text and for the list of the references at the end. Use a good citation-manager program and enter all the information for every article referenced--including titles. You won't want to have to go back and redo this if you've done it wrong!

Transform published articles into thesis chapters

Before you delve into the chapters you have to write from scratch, start by transforming your published articles and submitted manuscripts into thesis chapters. It's not just a matter of stapling your papers together and sticking them into your thesis, however. You'll need to break the publications into pieces and weave them into a cohesive narrative, making sure the various parts fit together nicely without redundancies or gaps in logic. When doing this, keep the following in mind:

  • Drastically cut back or rewrite the introduction section of each article. There is no need to repeat what you will have already explained in the general introduction and literature survey of your thesis. Don't just delete those introductions, however; parts of your manuscript intros will be useful for your thesis introduction, so paste any relevant text into the intro section of your thesis outline for later editing.

  • Cut the Materials and Methods section as necessary to avoid repetition with other chapters. Again, you'll probably want to paste some of the Materials and Methods text into the relevant sections in your thesis.

  • Include text that may have been cut from the final version of the article due to space restrictions.

  • Update your literature citations (see above).

If someone else wrote one of your publications (i.e., you did the experiments but a more senior person wrote the manuscript), we suggest you rewrite the bulk of the text in your own words. Even if experiments were done in collaboration, a thesis has only one author--you--and the words in it should be yours.

New material

After you've transformed your published articles into chapters, you will have to write new material for the remaining chapters. When you first start writing, it helps to begin with an easy section. This will give you confidence and get you into the writing habit. Because the methodology chapter is relatively straightforward, you might want to start with that one. If you've already written several methodology sections for your peer-reviewed articles, it won't take much time to prepare a first draft for your thesis.

Because a thesis has fewer space restrictions, you should take the opportunity to describe the details of your work that did not make it into published articles. In a thesis, it is better to err on the side of being too detailed than to risk leaving out crucial information. Be generous to the next generation of researchers; a detailed description of your progress and failures will save them a lot of time.

Writing up that last set of experiments

Now that you have worked your way through the initial chapters and have written most of your thesis, it is time to tackle writing up your final project. You probably haven't written an article on this research yet, so you'll need to decide whether to write the article first and then transform it into a chapter or do it the other way around.

If there is stiff competition in your field, your supervisor will probably insist that you write the article first. Otherwise, we suggest that you write the chapter first, as this approach will allow you to describe your work in detail. While the thesis is out for review with your dissertation committee, you can select the appropriate parts from the chapter and transform it into an article to submit to a peer-reviewed journal.

10 Tips for a Stress-Free Thesis

The introduction: The final hurdle

Although it comes first, the introduction will probably be the last chapter you write. The introduction is where you need to place your work in a broader context, explaining why the research is relevant to the scientific community and (assuming it is) to society.

Start thinking about your introduction long before you start writing your thesis. During your final year--or even earlier--create a file in which you collect ideas and article clippings that could be useful for the introduction. A file of good ideas will be a big help in writing a comprehensive and elegant introduction when the pressure is on.

The summary

The summary is the one section of your thesis that is sure to be read widely. In a few pages you will have to describe the main findings of your thesis research, so it is best to write this part after you have finished all the other chapters. Do not try to describe all your results in the summary--you're simply summarizing the bulk of your work. Be sure to designate in the summary which chapters contain particular findings.

Safeguard your work

We shouldn't have to remind you to back up your work, but we will anyway. Keep a copy of your thesis on an external hard drive, memory stick, or some other storage device. Back up daily and keep the copy (or copies) in a safe place. For extra security, keep a copy of your work-in-progress off-site on a remote server (in the event of fire or theft). The simplest way to do this is to open a Web-based e-mail account and regularly e-mail your work to yourself. There are also companies that offer online document-storage services.

Going for gold: Writing an error-free thesis

Because a thesis is usually written under severe time constraints, it is difficult to produce one without some typos and other minor errors. Spell checkers help, but they can't catch errors in those hard-to-spell technical terms. In addition, errors of grammar and syntax are not always highlighted, and minor scientific errors can be easily overlooked. Your goal, of course, is to have as few errors as possible.

We suggest you do two things to help make this a reality. First, put the manuscript aside for a short while after you've written the first draft. Once you've gained some distance from the material, read it over again with a sharp eye--not for content, but as a proofreader looking for typographical errors. Second, give a copy of your thesis to one or two trusted peers to read. Devise a creative way to reward them for every error they find (free cups of coffee or beer, or pizza, for example). This will give them an incentive to go through your thesis with a fine-toothed comb. If you can afford it, you may even consider hiring a professional copy editor to do this for you.

Most importantly, while writing your thesis, be sure to take care of yourself. Eat well, exercise, and get plenty of sleep so you're at your best when you sit down every day to write. This is the home stretch of your Ph.D., and you want to make sure you cross the finish line energized and ready for the next step.

Outlining your dissertation involves two main aspects: a practical list of what you need to do and a sketch of what you want to say.

First, there is a list of 31 items that you can use as the basis of your own to-do list. Writing your to-do list is the easiest part of your dissertation, being just a list of tasks. The tasks are arranged roughly in the order that you’re likely to do them, although some of the tasks overlap.

Second, the outline of your dissertation needs to say clearly what thoughts and ideas you’re going to include in each section of your dissertation. Sketching out what you need to say and structuring the presentation of your thoughts and ideas can be done in a number of ways but the two most popular methods are linear planning and concept planning (sometimes known as ‘mind-mapping’).

People often have strong feelings about which style they prefer; each method has pros and cons.

If you find creating the outline a useful part of your planning strategy, it’s a good idea to use the same outline style for each chapter. This helps you to write a dissertation with a clear, tight structure and avoiding repetition and confusion. A well-structured outline leads to a coherent dissertation.

Never think about your dissertation plan as set in stone – a good dissertation develops as you’re working on it and you’ve no need to be afraid of moving slightly away from your original plans. If you’re going wildly off track however, seek support from your supervisor as soon as possible.

Use linear planning for your dissertation

When using linear planning for your dissertation outline you list your tasks in order of doing them, starting with your first dissertation task through to the end. Linear planning makes for a very clear outline, but it’s more difficult to make changes as you go along than with a concept map. For your linear plan you can use the chapter headings recommended by your supervisor or the headings in the following list:

  1. Introduction and rationale:

    ‘Why on earth am I doing this is?’ ‘What led me to this topic?’

  2. Research question:

    Explain all the terms in the research question so that they’re clear.

  3. Outline of the literature:

    ‘Who are the key thinkers?’ ‘What are the key texts?’ ‘What is the underlying theoretical idea?’

    Now choose the 4a or the 4b heading.

  4. 4a.Research methodologies:

    Pros and cons of different methods, for example questionnaire, interview, observation

    Presentation of data – what I’ve found out

    Analysis of data/Discussion of data

  5. 4b.Main theorists and supporters:

    Counter arguments and supporters

    My own view of the argument (and supporting theorists)

  6. Conclusions and suggestions for further research:

    What I have found in relation to the research question

    Ideas for developing the dissertation topic

  7. Appendices and bibliography:

    Additional material that would interrupt the flow of writing

    All the references and materials used

Consider concept-mapping your dissertation

If you prefer a more visual approach to your outline plan of your dissertation, a concept or mind-map may suit you better. The disadvantage of the concept map is that you still have to write your dissertation in the traditional linear format, and so you’re going to have to convert your concept map into another form.

A key advantage of a concept map is that you can modify your listed tasks as you go along without having to completely rewrite your map each time. In the following figure, you can see an example of a concept map for a linguistics dissertation looking at how children speak. (The references are fictional.)

Create to-do lists for your dissertation

You need to be aware of the danger of making a to-do list: you can spend more time creating the list then you spend working on your dissertation. However, a comprehensive to-do list has some useful purposes:

  • Keeping in front of you an overview of your work.

  • Providing a clear record of your progress so that you know what’s left to do.

  • Helping build a sense of satisfaction as you tick things off.

When you’re creating your own to-do list, your list is tailored to your dissertation, but many of the following suggestions are likely to be elements of your list. Use the ‘To-do list’ as a basis for creating your own.

  • Choose a subject and carry out some initial investigations.

  • Have a look through dissertations written by other students.

  • Write a proposal/finalise your research question.

  • Ask your supervisor to sign off your research topic.

  • Decide what type of dissertation you’re going to write, empirical or non-empirical.

  • If you’ve chosen an empirical study, think through your research methodologies and check your decisions with your supervisor.

  • Spend some time organising how you’re going to keep your notes in order.

  • Read, read, read! Take notes of the literature as you go.

  • Read about the pros and cons of the different research methodologies and take notes as you go.

  • Start writing up the essential parts of your literature review and research methodologies – this is an ongoing process and the notes from your reading form part of your dissertation.

  • Plan the overall structure of your dissertation – create outlines for each chapter.

  • If your writing is not flowing by this stage, have a go at starting your introduction/rationale just to get some words on paper.

  • Arrange for your supervisor to look at some of your draft work.

  • Make sure that you’re all set for carrying out empirical work. For example, have you had ethical clearance? Have you sought permissions from subjects?

  • Sketch out the general arguments (for and against) for your dissertation. If your work is empirical, you’re looking for ideas to support your findings and provide a backdrop to your work. If your work is non-empirical, this to-do list item should be tackled in detail.

  • Empirical only: carry out your empirical work.

  • Empirical only: organise the data you collect and make a note of any difficulties (these notes are going to be very helpful for discussion when you come to finish writing your research methodologies).

  • Empirical only: analyse your data and discuss your conclusions with your supervisor.

  • Non-empirical only: discuss the key thinkers and detractors of your topic with your supervisor, checking that you’ve understood their ideas and that you haven’t left out any key thinkers.

  • Write up your findings/thoughts.

  • Write (or redraft) your introduction and conclusion.

  • Empirical only: check over diagrams, charts and so on, and make decisions about what you’re going to put in the appendices.

  • Arrange for your supervisor to look at some more of your draft work.

  • Pull together everything you’ve done so far checking that you’ve covered all the elements required – this is your first full draft.

  • Make a new to-do list for filling in any gaps and be sure that you’ve covered everything.

  • Write up your final version, by editing your existing work and completing any outstanding items.

  • As you complete chapters, ask a friend to proofread carefully.

  • Keep in touch with your supervisor, checking that she has enough time for you if you need extra help.

  • Be sure that you know the rules for binding your dissertation and check how long binding takes.

  • Keep the submission date for your dissertation right in front of you and be sure of submitting your dissertation on time.

  • Relax!
