I'm writing a chapter and I'm unsure how to structure it

Work out what the chapter has to do, then build an outline that follows the argument.

In short

Start here, today. Write the chapter's job in two sentences: “This chapter shows that… It does this so that the thesis can…” Then list the claims, usually three to six, that a reader would need to accept to believe it. This takes about 25 minutes.

After that, work through these steps. Choose one to jump to it.

  1. Name the chapter's job
  2. Outline by claims, not topics
  3. Write topic sentences first
  4. Signpost for the reader
  5. Give the chapter an introduction and conclusion
  6. Reverse outline a messy draft

  1. Name the chapter's job

    Write down what this chapter contributes to the whole thesis and what the next chapter needs from it. If you can't, go back to your research questions and ask which one, or which part of one, this chapter answers.

  2. Outline by claims, not topics

    Instead of headings like “Background” or “Study 2”, write each section heading as a sentence that makes a claim, such as “Most earlier studies measure attitudes once, so they miss how attitudes change.” Order the claims so each one builds on the last. You can shorten them into proper headings later.

  3. Write topic sentences first

    Under each section, write only the first sentence of every paragraph. Read them in order. If they carry the argument on their own, the structure works, and filling in the paragraphs becomes much easier.

  4. Signpost for the reader

    Tell readers where they're going and where they've been: a short roadmap near the start, a sentence opening each section that says what it does, and links such as “Having shown X, I now turn to Y.” It can feel repetitive to you. To an examiner reading the whole thesis, it's a relief.

  5. Give the chapter an introduction and conclusion

    Open with what the chapter does, why it matters for the thesis and how it's organised, usually in a page or less. Close by saying what the chapter has shown and what it sets up for the next one. A good chapter conclusion doesn't just summarise; it says how the argument has moved.

  6. Reverse outline a messy draft

    If you already have a draft that isn't working, number every paragraph and write one line for each: what it says and what it does (introduces, gives evidence, answers an objection, links). Mismatches and repeats jump out. Cut, merge and reorder at the outline level before you touch the prose.

Words you can use

Is this you? Signs to look for
  • Your chapter is organised by what you read or did, not by what you're arguing.
  • You've moved sections around several times and it still doesn't flow.
  • Your supervisor's comments say “what's the point here?” or “how does this connect?”
  • You couldn't summarise the chapter in two sentences.
Why this happens

Most chapter structure problems are argument problems. If you're not sure what the chapter is claiming, there's no principle for ordering the material, so it falls into the order you met it: paper by paper, test by test, interview by interview. That order makes sense to you because you lived it. A reader needs the order of the argument.

Each chapter also has a job in the thesis. A literature review sets up the problem and the gap your work addresses. A methods chapter justifies your choices. A results or analysis chapter answers a specific part of your question. Once you know the job, it becomes much easier to decide what belongs and what doesn't.

Conventions differ a lot between disciplines. Chapters in a history thesis, a qualitative sociology thesis and a lab-based thesis can look very different, so look at a few recent theses from your own department before settling on a shape.

When to bring someone in

Ask your supervisor to look at a one-page outline before you draft; it takes them minutes and can save you weeks. Writing centres are very good with structure problems, because an advisor from outside your field reads the way an examiner will and notices where the logic jumps. Your library's thesis repository will show you what recent chapters in your department look like.
