This study was designed to find: a suitable effect size (ES) measure or common metric (CM) for comparing the results of a set of single subject research (SSR) studies; and an easy way to convert the published graphs back into raw data from which ESs could be calculated. To meet the first objective, three possible formulas for measuring treatment…

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)

A descriptive and metanalytic research review indicates that physically attractive students are usually judged more favorably than their unattractive counterparts by teachers on several dimensions including intelligence, academic potential, grades, and social skills. The influence of moderating variables and possible mechanisms responsible for the…

A 1996 literature review of 75 "methodologically acceptable" studies concluded that bilingual education was not beneficial. A reexamination of the literature review found only 11 studies that actually were methodologically acceptable. The application of metaanalysis to those 11 studies shows that at least some native language instruction is…

Background: An inhibition deficit, including poor interference control, has been implicated as one of the core deficits in AD/HD. Interference control is clinically measured by the Stroop Colour-Word Task. The aim of this meta-analysis was to investigate the strength of an interference deficit in AD/HD as measured by the Stroop Colour-Word Task…
