This paper examines research studies, which focus on interventions commonly used with students who are learning disabled and identify effective methods that produce substantial benefits concerning reading comprehension. This paper synthesizes previous observation studies by conducting a meta-analysis of strategies used to improve the reading…

The aim of this paper is to examine a variety of features of research that might account for mixed findings of the relationship between teachers' subject matter knowledge and student achievement based on meta-analytic technique. Of several variables that might contribute to inconsistencies and variations in study findings, three features of…

This volume is part of the final report of the National Evaluation of Family Support Programs and details findings from a meta-analysis of extant research on programs providing family support services. Chapter A1 of this volume provides a rationale for using meta-analysis. Chapter A2 describes the steps of preparation for the meta-analysis.…

A meta-analysis was performed to synthesize existing research on the effect of gender differences on attitudes toward computers. A total of 106 studies were located from three sources, and their quantitative data were transformed into Effect Size. Nine variables were selected for coding: nationality of subjects, population group, sample size, type…

This article applies results of a previous meta-analysis of effective instructional practices with adolescents who have learning disabilities focusing on the factor, "Organization/Explicit," which contributed significant variance to effect size. This factor included the important instructional components of advance organization and explicit…

A meta-analysis of nine studies on psychotherapy with persons who have mental retardation found a wide range of research designs, types of interventions, and participants. The evaluation also pointed to a moderate degree of change in outcome measure and moderate effectiveness in terms of benefit to clients with mental retardation. (Contains…

Reviews issues raised in an earlier article that claimed that instructional media do not influence learning achievement or motivation. Topics discussed include differences between media and instructional methods; instructional technology; delivery technology; problems with meta analyses; thinking skills; cognitive processing; and research…

In this project, a resynthesis of the research dealing with student performance in new science curricula was conducted using refined statistical procedures. Results generally supported earlier meta-analysis studies. (CW)

Findings of positive effects of mastery learning on experimenter-made measures can be interpreted as supporting the view that this technique may help focus teachers on a given set of objectives. The claim that mastery learning can accelerate achievement, in general, in elementary and secondary schools is still awaiting evidence. (SLD)

Reviews, analyzes, and critically assesses a sample of articles reporting research findings related to the instructional effectiveness of computer-assisted instruction (CAI). Problems in CAI research are described, including validity of the experimental research design, and current trends in CAI research are discussed. (31 references) (LRW)

Data from 30 studies involving gender differences related to science achievement were synthesized using analyses of effect sizes and vote-counting estimation procedures. Reports that males showed advantages in biology, general science, and physics. (Author/YP)

Ten Minnesota Multiphasic Personality Inventory-2 (MMPI-2) fake-bad scales/indexes are reviewed with respect to their potential usefulness in evaluation of feigning mental illness, and a meta analysis of the MMPI is performed. One scale and two indexes were superior when effect sizes were calculated. (SLD)

Describes and discusses metanalysis and criticisms of the methodology. Reports on a pilot study which tested the feasibility of metanalytic methods in library science research using the literature on paper- or computer-based information retrieval. (28 references) (EA)

Summarizes a study using a series of meta-analyses to integrate the factors identified within and outside of the NASSP assessment center process into a consistent theoretical framework for improving principal preparation, assessment, selection, and performance. Proposes a model for future assessment center programs based on this analysis.…

Distributions of child attachment classifications in mother-child dyads in which the mother evidenced physical or mental problems were highly divergent from distributions for normal samples. Distributions of child attachment classifications in mother-child dyads in which the child evidenced physical problems were similar to distributions in normal…
