This review describes a meta-analysis of findings from 50 controlled evaluations of intelligent computer tutoring systems. The median effect of intelligent tutoring in the 50 evaluations was to raise test scores 0.66 standard deviations over conventional levels, or from the 50th to the 75th percentile. However, the amount of improvement found in…

We meta-analyze for impact and cost-effectiveness 94 studies from 47 conditional cash transfer programs in low- and middle-income countries worldwide, focusing on educational outcomes that include enrollment, attendance, dropout, and school completion. To conceptually guide and interpret the empirical findings of our meta-analysis, we present a…

This meta-analysis examined which classroom management strategies and programs enhanced students' academic, behavioral, social-emotional, and motivational outcomes in primary education. The analysis included 54 random and nonrandom controlled intervention studies published in the past decade (2003-2013). Results showed small but significant…

Since 1976, the U.S. Department of Housing and Urban Development (HUD) has relocated low-income children of color from public housing communities to less racially and economically isolated neighborhoods in an effort to improve their developmental opportunities. This article provides the first comprehensive evaluation summary of seven relocation…

This meta-analysis assesses the effectiveness of volunteer tutoring programs for improving the academic skills of students enrolled in public schools Grades K-8 in the United States and further investigates for whom and under what conditions tutoring can be effective. The authors found 21 studies (with 28 different study cohorts in those studies)…

Teachers and researchers can learn more about mastery learning by looking at the full picture instead of the small area on which R. E. Slavin focuses. Effects on precollege examinations constitute only a small part of the story; the larger literature presents many examples of its effectiveness. (SLD)

In program evaluation and policy analyses, utility supplants rigor as the first and most important criterion in judging literature reviews. Although R. T. Ogawa and B. Malen emphasize rigor, a utilization-focused evaluation emphasizes purpose and audience, both of which affect the conduct of a multivocal literature review. (SLD)

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)

A meta-analysis of findings from 108 controlled evaluations showed that mastery learning programs have positive effects on the examination performance of students in colleges, high schools, and the upper grades in elementary schools. Effects of mastery programs on student attitudes, instructional time, and college completion rates are discussed.…

This meta-analysis examines the effects of adventure programs on diverse outcomes such as self-concept, locus of control, and leadership. Analysis of 1,728 effect sizes from 96 studies shows that effect sizes varied substantially and improved as the length of the program and ages of the participants increased. (SLD)
