The effects of within-class grouping on student achievement and other outcomes were quantitatively integrated using one set of 145 effect sizes exploring grouping versus no grouping and a set of 20 effect sizes related to homogeneous versus heterogeneous ability grouping. Overall, results favored homogeneous grouping. (SLD)

Quantitative self-assessment studies that compared self-evaluations and teacher marks/grades were subjected to meta-analysis. Results of a meta-analysis of 51 studies are summarized. It is suggested that researchers should attend to both good design and to adequate reporting of self-assessment studies. (TJH)

Research on adult undergraduates in traditional American higher education is reviewed. A qualitative meta-analysis of 96 research reports indicates 5 domains of reality: image of implied deficiency; image of student entry and adaptation; image of description and characterization; image of psychosocial development; and image of equity and outcome.…

Meta analysis techniques were used to synthesize research on teaching students how to control variables when designing an experiment. The review included 65 controlled studies. Findings are reported in terms of the influence on effect sizes of characteristics of the study, instruments used, treatments applied, and results' utilities. (SLD)

Meta-analytic techniques tested the effect on learning of the interaction of prior achievement with instructional support. This review of nine studies indicates that differences in prior achievement levels can be reduced through instructional treatment. Results support the use of meta-analyses for other investigations of aptitude-treatment…

This meta-analysis reviewed 58 effect sizes from 40 reports on the instructional effects of feedback in tests or similar situations. Mediated instructional feedback for retrieval and application of specific knowledge appeared to stimulate correction of erroneous responses when its reception was encouraged. (SLD)

Asserts that the central problem of the analysis by M. Wang, G. Haertel, and H. Walberg is that they tend to view the teacher, at least implicitly, as the compliant beneficiary of the knowledge of the educational researcher. Any knowledge base that aims to affect classroom practice should take into account and respect the teacher's world.…

Asserts that because M. Wang, G. Haertel, and H. Walberg never clarify the contours of their "knowledge base for school learning," it is difficult to know what their broad-based comparison of research studies has really yielded. Explores dilemmas posed by the methodology of the study. (SLD)

To estimate the relative effects of three types and three combinations of feedback on children's discrimination learning, a meta-analysis was performed on the findings of 89 studies. In general, reward compared to punishment or to reward plus punishment is the least efficient method of feedback for teaching children discrimination materials.…

Results from a meta-analysis of findings on the effectiveness of coaching for achievement tests from 30 controlled studies of coaching programs are presented. Coaching typically raised achievement test scores by .25 standard deviations. Effects varied with the level of training intervention. (Author/PN)

Results from a meta-analysis of 26 controlled studies on the effects of accelerated instruction on elementary and secondary school students are presented. The examination performance of accelerates surpassed the performance of equivalent age and intelligence nonaccelerates and equalled the performance of same-grade but older, talented…

Through meta-analysis, 51 studies are examined in which interventions were aimed to enhance student learning by improving student use of either one or a combination of learning or study skills. Results obtained, through categorizing the interventions in hierarchical levels of structural complexity and as either near or far in terms of transfer,…

A review of various models of the relationship between research and teaching in universities is presented, and the evidence necessary to assess each model is outlined. A meta analysis of 59 studies demonstrates that the relationship is zero. Suggestions are provided for future directions. (Author/SLD)

Best-evidence synthesis was used to review 29 research papers published in English that evaluate the effects of ability grouping on student achievement in secondary schools. Six randomized experiments, 9 matched experiments, and 14 correlational studies were reviewed. Findings do not indicate beneficial effects of ability grouping on achievement.…

This meta-analysis examines patterns of sex differences in teacher-initiated teacher-student interactions. While extensive research has examined factors that influence student evaluations of effective and ineffective teachers, this study examines whether teacher-initiated interactions with students, such as praising or blaming, vary as a function…
