This review examined the literature on peer tutoring in reading with students with disabilities, using the methodology of best evidence synthesis. This approach combines positive aspects of meta analysis with traditional integrative review procedures. It requires all studies reviewed to meet stringent a priori standards. Analysis of the 11 studies…

This report reviews research on the effects of between- and within-class ability grouping on the achievement of elementary school students. The review technique, known as "best-evidence synthesis," combines features of meta-analytic and narrative reviews. Overall, evidence does not support assignment of students to self-contained classes…

The meta analysis reported in this paper considers the implications of combined correlational evidence for the nature of the relationships of mathematical and spatial skills, and for the possibility that spatial skill underlies gender differences in favor of males on mathematical tasks. In all, 136 studies reported in 116 articles and…

Developing good criterion measures of professional performance is difficult. If criterion-related validity evidence for certification requirements could not be generalized beyond the specific context in which it was obtained, gathering that evidence would probably not be worth the effort. This paper examines two possible approaches to the…

Monte Carlo studies of statistical tests are prominently featured in the methodological research literature. Unfortunately, the information from these studies does not appear to have significantly influenced methodological practice in educational and psychological research. One reason is that Monte Carlo studies lack an overarching theory to guide…

This bibliography identifies reports of research on correlates, causes, effects, and treatment of test anxiety. The listing was developed for a synthesis of research, performed by meta-analysis at Adrian College, Michigan in 1986-87. Guidelines for including studies were applied as follows: (1) the research concerned academic test anxiety, using…

Part of a series, this preliminary report is on a meta-analysis study of successful and unsuccessful transition of handicapped youth from secondary education to postsecondary settings. The study had four major objectives: (1) to review annual progress reports of federally funded (Office of Special Education and Rehabilitation) transition projects,…

In 1981 a meta-analysis of research in science education was completed by a team of researchers under the direction of Ronald Anderson at the University of Colorado. Individual teams synthesized the extant research using meta-analysis procedures. One of the syntheses showed that the post-Sputnik or "new" science programs on the whole…

A policy of reducing class size seems sensible, but might have costly, far-reaching implications for students, teachers, and public support for schools. The purpose of this research brief is to summarize 100 class size research studies from 1950 to 1985 and to regroup them into 18 areas of concern. The cluster analysis approach was designed to…

The feasibility of employing survey data that uses the states of the United States as the societal units in macro-level sociological research was studied. The range of issues available for research opened to investigation would be greatly expanded if it were possible to aggregate national survey data to produce state-level statistics for variables…

The one-page abstract summarizes "Brain Research: Implications for the Education of Exceptional Children," an ERIC Computer Search Reprint containing bibliographic information and abstracts of 115 documents. Citations are described in five sections: learning disabilities, autism, other learning handicaps, assessment techniques, and instructional…

Methods for meta-analysis have evolved dramatically since Gene Glass first proposed the term in 1976. Since that time statistical and nonstatistical aspects of methodology for meta-analysis have been developing at a steady pace. This guide is an attempt to provide a practical introduction to rigorous procedures in the meta-analysis of social…

The purpose of this study was to determine the types of research methods used to study cognitive processing development in gifted learners, from 1975-1986. Of 870 research publications identified on giftedness, 522 publications (60 percent) dealt with cognitive processing development. Research designs used most frequently were causal-comparative,…

This paper contains summaries of the findings of research and meta analyses conducted on the effectiveness of computer-based instruction (CBI) on student achievement. Eight conclusions, based on the CBI research are then given: (1) when CBI and traditional instruction are compared, students receiving CBI demonstrate equal or better achievement;…

Meta-analysis techniques were used to determine whether or not there are differences in General Aptitude Test Battery (GATB) validity and test scores between samples from the Northern, Southern, and Western United States census areas. The sample consisted of 26,111 subjects from 122 validation studies of the Specific Aptitude Test Battery (SATB).…
