Map a textbook chapter without copying it

Give the chapter a question

A heading such as “Memory” is a subject, not yet a study task. Try “What influences whether a memory can be retrieved?” instead. A question gives every branch a job: it should help answer, qualify, or challenge that question.

Skim the introduction, headings, diagrams, and conclusion first. Sketch three to five tentative branches. Avoid copying the complete table of contents automatically; the author's order may not be the structure you need for an assignment.

Read a section, then write without looking

After a short section, look away and write one sentence explaining its point. Shorten that sentence into a node label. Add an example you can explain and a note about any limitation. Then reopen the book to correct your version.

For each branch, use a repeatable note structure: explanation, evidence or example, limitation, and page reference. This prevents a definition from becoming detached from the conditions under which it applies.

Use quotation marks for words copied exactly and keep the page number with them. A paraphrase still needs a source when you later use it in assessed work. Your map should not blur the boundary between your explanation and the author's wording.

A reusable chapter structure

• Main question: what the chapter is trying to explain.
• Key concepts: definitions you need to use accurately.
• Explanations: mechanisms or arguments linking those concepts.
• Evidence: studies, worked examples, or observations.
• Limits: exceptions, assumptions, and competing explanations.
• Unresolved: questions for the next reading or seminar.

These are optional starting branches, not a mandatory template. A mathematics chapter may work better as assumptions, theorem, proof idea, and applications. Adapt the structure to the kind of reasoning the text demands.

Keep the map deliberately smaller than the chapter

If every paragraph becomes a node, you have created a second textbook with a less convenient layout. Keep the canvas for relationships. In Mappy, move detailed writing into expanded notes and retain the short label as a signpost.

Finish by writing a short answer to the original question using only your map. If the answer has a missing step, return to that part of the text. If two branches repeat the same point, combine them. Stop when the map helps you explain the chapter, not when every page has a matching branch.

For revision, pick a different example and see whether the same explanation still works. This is a more revealing check than recognizing the wording of a familiar definition.
