Timing of Feedback and Verbal Learning

A meta-analysis of findings on feedback timing and human verbal learning showed that a variety of results have been obtained in 53 separate studies of the topic. Applied studies using actual classroom quizzes and real learning materials have usually found immediate feedback to be more effective than delayed. Experimental studies of acquisition of test content have usually produced the opposite result. Laboratory studies of list learning have produced a variety of results, but the variation in results seems to be related systematically to features of the studies.
