Stop rereading: how to study a textbook chapter so it stays.
Rereading and highlighting feel like studying and test poorly. A four-step method that turns a chapter into retrievable memory.

Rereading is the most common study method and one of the least effective. It creates familiarity, which feels like knowledge until a question asks you to produce the fact without the page in front of you. Here is how to work through a chapter so that the second pass is retrieval, not recognition.
Step one: read once, with questions
Before reading, turn each heading into a question. "Ethical decision-making models" becomes "What are the ethical decision-making models and how do they differ?" Then read to answer it. Do not highlight. Highlighting marks the page, not your memory.
Step two: close the book and write
At the end of each section, close the book and write what you remember on a blank page. Bullet points, incomplete, wrong in places; that is fine. Then open the book and correct the page in a different color. The corrections are your gaps, and they are exactly what your flashcards should contain.
Step three: make cards from the gaps only
Do not make cards for everything in the chapter. Make them for what you could not retrieve in step two. A card should ask one question with one answer. "Corey's eight-step model: step 4?" is a good card. "Ethical decision-making" is not.
Step four: return on a schedule
Review the cards the next day, three days later, a week later, and then weekly. Reread the chapter never, unless a practice test shows the area is still weak. If it is, do steps one and two again on the relevant section only.
Why this feels worse and works better
Retrieval is effortful and exposes what you do not know. Rereading is smooth and hides it. The discomfort is the signal that the memory is being strengthened. Students who switch from rereading to this method typically report that studying feels harder and their practice scores rise within two weeks.
A chapter studied this way takes about the same time as reading it twice. The difference is that you can use it on exam day.
What the research says
This is not a study hack; it is one of the best-replicated findings in cognitive psychology. Roediger and Karpicke's 2006 studies had students either reread a passage or take a free-recall test on it after one reading; the rereading group felt more confident and did better on an immediate test, and the testing group remembered far more a week later. Dunlosky and colleagues' 2013 review of ten study techniques rated practice testing and distributed practice as high utility, and rereading, highlighting and summarizing as low. The method above is the first two, applied to a chapter.
The mechanism matters because it tells you what to protect. Retrieval strengthens the memory and also tells you where it is weak; rereading does neither, and the fluency it creates is exactly what makes you stop studying something you have not learned. Spacing works because a slightly forgotten memory, retrieved, comes back stronger than one retrieved while still fresh. So the next-day review should feel a little hard. If every card is easy, the interval is too short.
Applying it to the course lessons
The lessons on this site are built for the method. Each ends with a two-minute brain dump: write what you remember before the quiz, without scrolling up. That is step two. The quiz is the test, and its explanations are the corrections in a different color. The flashcards attached to each lesson are the step-three cards, pre-written, and the spaced schedule in the Daily 10 is step four, run for you. The one thing the site cannot do is make you close the lesson before you write; that part is the whole method.
If you are also working from a textbook, treat the book as the first read and the lesson as the retrieval check. Read the chapter with the headings as questions, then come to the matching lesson and take its quiz cold. The score will be worse than you expect and more useful than rereading. Then let the explanations and the cards carry the chapter from there.
Three mistakes people make when they switch
Making cards for everything. The chapter has two hundred facts; you could not retrieve forty of them; forty cards is the right number. Two hundred cards is rereading with extra steps, and the deck becomes a chore you quit. Second, testing only immediately. A recall attempt right after reading is still mostly short-term memory; the test that matters is tomorrow's. Write the page at the end of the section, but trust the next-day review as the real measurement.
Third, reading the explanations instead of retrieving them. When a card comes back, the reflex is to flip it and nod. Say the answer out loud or write it before you flip, every time. A card you flipped without producing the answer has taught you nothing except that the answer looked familiar, which is the problem the method exists to fix.
