This paper summarizes and analyzes data from studies of differential validity and differential prediction for blacks versus whites and females versus males. Forty studies on racial differences and 53 on gender differences were selected from searches of the ERIC, PsychInfo, and Dissertation Abstracts International databases; Buros' Mental…

The second of four symposium papers brings together the results of four separate statistical analyses of findings on computer-based instruction (CBI) in 199 comparative studies, of which 32 were conducted in elementary schools, 42 in high schools, 101 in universities and colleges, and 24 in adult education settings. Each was a controlled,…

Educational programs and evaluations which were submitted to the Department of Education's Joint Dissemination Review Panel (JDRP), in order to be named validated programs, were studied to identify program characteristics associated with large versus small effect size. Effect size was calculated for 165 out of 232 submittals reviewed by JDRP from…

The effectiveness of an Education Consolidation Improvement Act Chapter 1 program was studied in a large urban school district. A common problem in evaluating remedial programs is that pretest/posttest achievement gains often indicate the effects of the entire curriculum, rather than those specific to the remedial class. In this district, over…

This ongoing project, conducted in four municipalities in Sweden, is investigating the ways in which schools and teaching are affected by various local communities and the ways in which central directives are transformed into a local educational reality. A diverse range of data have been collected, including demographic data from the…

Reviews the results of a meta-analysis that evaluated 208 variables derived from 98 studies incorporating music as a contingency for education and therapeutic objectives. Demonstrates that contingent music was more effective than was continuous music and nonmusic stimuli used in these studies. Includes a list of the studies analyzed. (MJP)

Data drawn from 30 journal articles and ERIC documents reporting on gender differences in natural science achievement were re-examined. Three meta-analysis methods were used: (1) vote counts and vote-counting estimation procedures; (2) tests of combined significance; and (3) analyses of effect sizes. The three methods produced seemingly…

This meta analysis of 101 studies of computer-based education in colleges highlights examination performance, student attitudes toward instruction and computers, the relationship of publication source to study outcome, and time needed for instruction. One hundred twenty-one references are listed. (Author/LRW)

This study employs meta-analysis and cost-effectiveness instruments to evaluate and compare cross-age tutoring, computer assistance, class size reductions, and instructional time increases for their utility in improving elementary school reading and math scores. Using intervention effect studies as replication models, researchers first estimate…

This meta-analysis of 49 comparative studies shows that mastery testing has positive effects on student learning, but the size of effect depends on the stringency of the criterion used and the degree of experimental control. The effects of instructional time, student attitudes, and differences in ability levels are also addressed. (Author/LRW)

The purpose of this study was to determine the extent to which mastery testing contributes to instructional effectiveness and to determine the size of its effects in different outcome areas, such as aptitude and instructional time. A meta-analytic methodology was used to integrate findings from experimental studies. Twenty studies examined…

Forty studies using one or more components of Lozanov's method of suggestive-accelerative learning and teaching were identified from a search of all issues of the "Journal of Suggestive-Accelerative Learning and Teaching." Fourteen studies contained sufficient statistics to compute effect sizes. The studies were coded according to substantive and…

This metaanalysis of 32 comparative studies shows that computer-based education has generally had positive effects on the achievement of elementary school pupils. However, these effects are different for off-line computer managed instruction and interactive computer assisted instruction (CAI); interactive CAI produces greater increases in student…

This volume offers a systematic review of the literature on communication education and instruction. Making meta-analysis findings accessible and relevant, the editors of this volume approach the topic from the perspective that meta-analysis serves as a useful tool for summarizing experiments and for determining how and why specific teaching and…

Results in 487 reports were integrated by meta-analysis to study characteristics of problem solvers, conditions for harder and easier problems, effects of different instructional methods on problem-solving performance, and effects of classroom-related conditions on problem-solving performance. Problem solving related positively to measures of…
