A chapter is easier to navigate when you know what you are trying to learn. Previewing its structure can help you connect details to the larger argument, but a preview does not replace careful reading. Scan the headings, diagrams, and summary. Turn two headings into questions. Read one section and pause to answer them in your own words. Note how the evidence supports the claim and which terms need clarification. For a history chapter, separate events, causes, and interpretations. For a science chapter, connect an observation to the mechanism offered to explain it. When a paragraph is unclear, identify the exact sentence or term causing difficulty before rereading the entire section. Try it today: Before your next reading session, write a purpose sentence: “By the end, I want to explain…” Finish by testing whether your notes actually answer it.
