This metanalysis reviews 32 studies that compared 2 groups of students receiving identical writing instruction, with only 1 group using word processing for writing assignments. Word processing improved the quality of student writing but did not improve student attitudes. Suggestions are given for using word processing more effectively. (SLD)

A review of 66 reports involving science education for students with disabilities finds that specific instructional strategies and techniques have produced generally beneficial effects. Results support previous recommendations for science education based on documented characteristics of these students using appropriate instructional variables,…

This meta-analysis with literature review considers whether the self-concepts of gifted and nongifted children differ and explores the effects on self-concept of labeling a child as gifted and placing the child in special programs. Studies indicate a generally higher academic self-concept among gifted students. (SLD)

This article summarizes the critical findings of recent research syntheses concerning intervention with students who have learning disabilities. The syntheses examined research on higher-order processing and problem- solving, reading comprehension, written expression, and grouping practices associated with improved outcomes in reading. Principles…

This article uses meta-analytic findings to evaluate six special education interventions: psycholinguistic training, perceptual-motor training, modality-matched instruction, and treatments for attention deficit hyperactivity disorder (stimulant medication, diet modification, and social skills training). Findings are related to decision making in…

This study summarizes the results of a quantitative synthesis of the retrievable primary research dealing with the effects of new science curricula on student performance. This study synthesizes the results of 105 experimental studies involving more than 45,000 students and utilizes the quantitative synthesis perspective to research integration…

A quantitative synthesis of multivariate studies in science education during the past ten years yields evidence to support a model of achievement in science very much like that currently proposed in the literature of expert problem-solving. Despite previous claims, spatial visualization and verbal ability predict additional variance in achievement…

This research review summarizes two major sets of meta-analyses on five kinds of ability grouping programs: (1) XYZ classes (high, middle, and low classes); (2) cross-grade grouping; (3) within-class grouping; (4) accelerated classes; and (5) enriched classes. One group of meta analyses concluded that the strongest benefits from grouping were…

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…

Based on 128 studies comparing the effects of technology instruction and conventional instruction in Japanese elementary and secondary schools, this meta-analysis describes the findings for student achievement (116 studies), aptitude treatment correlation (9 studies), and student attitude (8 studies). Findings are analyzed by both type of media…

The results of synthesizing 40 studies regarding the effects of gender characteristics of instructional materials on students indicate that sex-equitable materials can improve both male and female students' learning experiences and assist in developing gender-balanced associations and more flexible sex role attitudes. Effects on preference and…

This final report discusses the activities and outcomes of the Self-Determination Synthesis Project (SDSP), a project designed to synthesize, corroborate, and communicate the professional knowledge base on the effects of self-determination and self-advocacy interventions for children and youth with disabilities. The SDSP used both quantitative and…

This paper reports on an examination of the effects of leadership practices on student achievement. It includes a meta-analysis of nearly every available study since the 1970s, including doctoral dissertations, that indicated it examined the effects of leadership on student achievement. From a total of more than 5,000 studies, 70 met the…

This is the fourth volume in a series of monographs from the Comprehensive Community Mental Health Service for Children and Their Families Program, which currently supports 41 comprehensive system of care sites to meet the needs of children with serious emotional disturbances (SED). This volume identifies the essential elements of wraparound…

Synthesizes research findings from 10 studies on urban homeless families; and details their demographic characteristics, including the number of children, race, ethnicity, and family composition. Focus is on mothers with children and the effects of homelessness on children. (SLD)
