Discusses R. Slavin's best-evidence synthesis method as an alternative to traditional meta-analysis and review techniques. Explains the inherent weaknesses of the technique Slavin uses and how the techniques can be misused. (RB)

Meta-analysis techniques were used to synthesize research on the effectiveness of three major activity-based elementary science programs: (1) the Elementary Science Study, (2) Science--A Process Approach, and (3) the Science Curriculum Improvement Study. Implications for both widespread adoption and curricular decisions, as well as long term…

Subjected 48 quantitative peer assessment studies that compared peer and teacher marks to meta-analysis. Peer assessments were found to resemble teacher assessments more closely when global judgments based on well understood criteria were used rather than when marking involved assessing several individual dimensions. (Author/SLD)

The results of a meta-analysis that found that rewards do not threaten intrinsic motivation have not been well accepted by those who argue rewards produce negative effects under a wide range of conditions. Nevertheless, the results and conclusions of the meta-analysis are held to be valid. (SLD)

A review of 39 studies indicates that achievement-test scores decline over summer vacation. Meta-analysis results from combining the 13 most recent studies indicate that the summer loss equals about one month on a grade-level equivalent scale. Discusses implications for school calendar changes. Contains 68 references. (SLD)

Self-reported grades are heavily used in research and applied settings because of the importance of grades and the convenience of obtaining self-reports. This study reviews and meta-analytically summarizes the literature on the accuracy of self-reported grades, class ranks, and test scores. Results based on a pairwise sample of 60,926 subjects…

A quantitative synthesis of the results from 66 studies indicated that boys' and girls' science achievement is positively related to affect, but the relationship is weaker than expected. Science achievement correlates more strongly with cognitive abilities than with affect. (Author/BW)

Two papers respond to an article by P. Atkinson, S. Delamont, and M. Hammersley (1988) critiquing papers by E. Jacob (1987, 1988) on qualitative research traditions. The use of T. Kuhn's concept of "paradigm" and the criticism that the British were not included in the Jacob's study are addressed. (TJH)

This review brings together 21 studies on the long-term effects of school desegregation on the life chances of African American students. These studies draw on perpetuation theory, a macro-micro theory of racial segregation. They support the idea that interracial contact in school can help blacks overcome perpetual segregation. (SLD)

Multivocal literatures are comprised of all accessible writings on a common topic and embody the views of diverse authors. The exploratory case study method is proposed as a way to ensure rigor in reviews of such literatures because it addresses problems associated with the selective use of data. (SLD)

The conclusion of J. Cameron and W. D. Pierce that rewards do not pose a threat to intrinsic motivation (1994) is a misrepresentation of the literature based on a flawed meta-analysis. Their analysis is more an attempt to defend behaviorist turf rather than meaningful consideration of relevant data and issues. (Author/SLD)

Consultation on student ratings is recognized as an important strategy to support university teachers in learning from student ratings feedback. However, there is little evidence to suggest which practices and strategies are most important for successful consultation. As the use of student ratings increases, such evidence becomes increasingly…

This meta-analysis reviewed the literature on socioeconomic status (SES) and academic achievement in journal articles published between 1990 and 2000. The sample included 101,157 students, 6,871 schools, and 128 school districts gathered from 74 independent samples. The results showed a medium to strong SES-achievement relation. This relation,…

A meta-analysis of the comparative distance education (DE) literature between 1985 and 2002 was conducted. In total, 232 studies containing 688 independent achievement, attitude, and retention outcomes were analyzed. Overall results indicated effect sizes of essentially zero on all three measures and wide variability. This suggests that many…

This meta-analysis summarizes teaching effectiveness studies of the past decade and investigates the role of theory and research design in disentangling results. Compared to past analyses based on the process-product model, a framework based on cognitive models of teaching and learning proved useful in analyzing studies and accounting for…
