This examination of the research on computer-based instruction for the major academic subjects in the elementary and secondary grades considers three varieties of empirical data--surveys of computer-using teachers, school district program evaluations, and experimental field studies. A discussion of the findings of two national surveys of…

A meta-analysis of nearly 200 research studies, plus a review of the literature on staff development, point to the importance of program design in providing insights that teachers can use in their classrooms. Appended are 32 references. (MLF)

Based on data from 22 controlled studies, this article presents a meta-analysis of the effects of examiner familiarity on children's test performance. It was found that examiner familiarity raised scores especially when subjects were: (1) of low socioeconomic status; (2) tested on difficult tests; and (3) knew the examiner for a long duration.…

A quantitative summary of 15 studies indicated that African-American/Latino students receive more negative feedback from teachers in the classroom than do Euro-American students. In addition, teachers interact less frequently with African-American/Latino students than Euro-American students. No difference based on race existed in the amount of…

Conducted a meta-analysis of 21 studies to determine the impact of parental involvement on minority students' academic achievement. The impact of parental involvement was significant for all minority groups studied. Also for all groups, parental involvement affected all academic variables by at least two tenths of a standard deviation unit.…

This meta-analysis looked at outcomes of school-based interventions aimed at enhancing the self-concept of students with learning disabilities, specifically effect sizes in relation to students' self-concepts prior to the intervention. Results indicated that only students with documented low self-concept benefited significantly from intervention.…

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)

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…

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)

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 executive summary reports on a study which utilized meta-analysis and best-evidence synthesis techniques to evaluate 13 research studies on the academic, social, and psychological effects upon learners who are gifted and talented of three grouping practices: (1) ability grouping for enrichment; (2) mixed ability cooperative grouping for…

The statewide teaching performance assessment instruments being used in Georgia, North Carolina, and Florida were examined. Forty-one reliability and validity studies regarding the instruments in use in each state were collected from state departments and universities. Georgia uses the Georgia Teacher Performance Assessment Instrument. North…

The great concern in recent decades over the trends of declining student achievement scores and increased cost of schooling has prompted speculation about how these trends might relate to one another. Much like popular opinion, research findings from studies of this relationship have often been contradictory. This study presents results from a…
