Effect of Paced and Unpaced Practice on Skill Application and Retention: How Much Is Enough?

This study examined the relative benefits of mastery learning, overlearning, and fluency-building instructions for academic performance and long-term retention. College students enrolled in introductory quantitative methods classes (n = 168) were asked to practice every week with a computerized flashcard program until they attained various mastery criteria. The results confirmed that practicing until mastery improved individual exam scores, group success rates, and long-term retention. Moreover, overlearning provided additional benefits, especially in long-term retention. However, fluencybuilding instructions did not further increase academic achievement or longterm retention. Despite the alleged detrimental effects of drill and practice on motivation, a positive relationship was found between amount of practice and attitudes toward the course, the subject matter, and practice activities.
