Diagnostic Test 18

In a randomized study that equalized total study time, students who spent part of each session completing low-stakes retrieval quizzes scored substantially higher on a test given two weeks later than students who reread or did time-matched filler tasks.

In one class, quiz groups scored higher than rereaders on a quiz administered immediately after studying.

A student reports that daily quizzing "made me feel more confident" before the exam.

Schools that adopt frequent quizzes also assign more homework on average.
