Rereading a chapter feels like studying. A week later, the kids who quizzed themselves remember more than the kids who read it again.
Rereading is a comfortable waste of time
A child reads the chapter, then reads it again, then tells you they studied. The page looks familiar. That feeling is not the same as being able to recall the fact later.
In 2006, Henry Roediger and Jeffrey Karpicke had students study prose passages. One group kept rereading. Another group took a recall test. After five minutes, extra reading looked fine. After a week, the tested group remembered more. The reread group had been fooled by how easy the second pass felt.
What the reviews actually recommend
John Dunlosky and colleagues rated ten common study methods in Psychological Science in the Public Interest. Practice testing and spreading practice across days earned the strongest marks. Highlighting and rereading earned weak ones. That is awkward, because those two are what most kids do when you say "go study."
A quiz is not a verdict. It is the practice. The struggle to pull an answer out of memory is the part that makes the memory last.
- Close the book and ask five questions before you let them look again.
- Have them write what they remember on a blank page, then check the text.
- Turn the week's words or facts into a short game that requires the answer, not a lucky guess.
- Save rereading for the items they missed.
Keep the quiz short enough to finish
You do not need a formal exam. Five oral questions after a history chapter, a hangman round on the science terms, or a crossword built from this week's vocabulary all force retrieval. Stop when they start guessing. Come back tomorrow and ask the same items again.
If they get everything right on the first try, the material was too easy or they already knew it. Move on. If they miss most of it, teach the piece again instead of assigning another reread.
