Analyses of the results of 23 reports on coaching for the Scholastic Aptitude Test (SAT) indicated that, on the average, coaching can help increase SAT scores. The considerable variability in the results of 48 studies reflected the many factors influencing coaching effectiveness and the wide variety of study designs. (SLD)

This article presents a meta-analysis of studies of the effects of special homogeneous classes versus regular heterogeneous classes on achievement and nonachievement outcomes of gifted students. The principal findings indicate that the gifted students in special classes achieved more than their gifted counterparts in regular classes. (Author/IAH)

A meta-analysis determined the importance of feedback in computer-based learning; 59 studies were collected and evaluated for inclusion in the meta-analysis in terms of design, sample size, and availability of appropriate statistics. Achievement outcomes were found to be greater for the feedback group than the control group. (AEF)

Using a "review of reviews" methodology, this literature synthesis on stimulant use with children with attention deficit disorder compared three reviews from each of three review types (traditional, meta-analytic, general audience). A consensus was found to exist about the expected benefits and the acknowledged limitations of stimulant medication.…

A meta-analysis of studies on overeducation and undereducation in the labor market reveals that of the four different definitions of overeducation distinguished in the literature, only the one based on variation in years of education within occupational groups appears to yield significantly lower-than-average rates of overeducation. (Contains 4…

Power analysis of studies in Greene's meta-analysis of bilingual education programs found that many studies of the past 30 years were statistically weak and uninterpretable. Effect size analysis of Thomas and Collier's 15-year study found that their longitudinal model best explains 30 years of bilingual education research and can serve as a…

A meta-analysis of gender differences examined statistics achievement in postsecondary level psychology, education, and business courses. Analysis of 13 articles (18 samples) found that undergraduate males had an advantage, outscoring females when the outcome was a series of examinations. Females outscored males when the outcome was total course…

Asserts that reviews like that of M. Wang, G. Haertel, and H. Walberg are stimulating and useful in thinking about educational research, but they are nearly useless in thinking about educational policy and practice. It is not clear what is meant by "knowledge base," and the finding about proximal and distal variables is simplistic. (SLD)

Describes meta-analysis, a quantitative approach to conducting literature reviews. Illustrates the power of this technique by reporting the quantitative effects of cooperative learning on chemistry achievement in high school and college classes. (Contains 32 references.) (WRM)

A meta-analysis of 10 studies on Asperger Syndrome (ASP) and autism suggests that children with ASP perform better on intelligence and cognitive measures and on adaptive behavior functioning measures. The results suggest that ASP can be viewed as a distinct diagnostic category and can be separated from children with autism. (Author/CR)

Twenty-four meta-analyses in mental retardation, learning disabilities, and emotional/behavior disorders were reviewed and analyzed across six domains of information necessary for securing face validity of published meta-analyses. Wide variations that could influence summative results were found. Additionally, temporal analysis of 44 meta-analyses…

This study examined the use of training program evaluation results in corporate universities. Specifically, the study attempted to determine which organizational members use evaluation data, and for what purposes, and identify the factors that are related to the use of evaluation results. The study was designed to test the appropriateness of the…

Informal Reading Inventories (IRI) are often recommended as instructionally relevant measures of reading. However, they have also been criticized for inattention to technical quality. Examination of reliability evidence in nine recently revised IRIs revealed that fewer than half report reliability. Several appear to have sufficient reliability for…

Disclosing information, thoughts, and feelings about personal and meaningful topics (experimental disclosure) is purported to have various health and psychological consequences (e.g., J.W. Pennebaker, 1993). Although the results of 2 small meta-analyses (P. G. Frisina, J. C. Borod, & S. J. Lepore, 2004; J. M. Smyth, 1998) suggest that experimental…

This article provides a synthesis of research in which parents provided academic instruction to their own children. The effectiveness of parent tutoring in 37 studies was examined across grade level, basic skill area (e.g., reading, math), training feature (e.g., treatment length, availability of consultation), treatment fidelity, type of…
