Literature on achievement effects of practical applications of group-based mastery learning in elementary and secondary schools over at least four weeks is examined, using the best-evidence synthesis review technique (a combination of meta-analysis and narrative reviews). There was essentially no evidence to support the effectiveness of…

This article examines the literature on achievement effects of practical applications of grouped-based mastery learning in elementary and secondary schools. The review found no evidence to support the claim that mastery learning improves student performance on standardized achievement measures. (RB)

In this rejoinder, R. Slavin responds to a broad range of technical and philosophical issues about his use of best-evidence synthesis to research the effectiveness of mastery learning. (RB)

Mastery Learning and Student Team Learning are two widely used instructional methods designed to confront the problem of student diversity in group-paced instruction. This study evaluated Mastery Learning, Student Team Learning, and a combination, in 43 inner-city math nine classes over a full school year. Results indicated greater achievement on…

Findings of positive effects of mastery learning on experimenter-made measures can be interpreted as supporting the view that this technique may help focus teachers on a given set of objectives. The claim that mastery learning can accelerate achievement, in general, in elementary and secondary schools is still awaiting evidence. (SLD)

Discusses alterable elements of classroom organization, traditional approaches to instructional improvement, and "component building," an alternative approach to education. The component-building approach involves an extensive program of field experimental research on classroom practices that are or could become components of complete…
