Immediate vs. Delayed Feedback in a Computer-Managed Test: Effects on Long-Term Retention.

摘要

Four groups of college undergraduates took a multiple-choice computer-managed test. Three of these groups received informative feedback (the entire item with the correct answer identified) either (1) immediately item-by-item (2-second delay), (2) following the entire test (20-minute delay), or (3) 24 hours later (24-hour delay). The fourth (control) group received no feedback. Scores on a criterion test, given 1 to 3 weeks later, showed that retention was significantly better for the two delayed feedback groups (20-minute and 24-hour delay) than for the immediate feedback group (2-second delay). These results confirmed previous findings of laboratory experiments--that retention following delayed feedback is not degraded by the delay. (Author)
