This study had two purposes. First, we sought to compare the overall effectiveness of different types of fluency interventions for students with learning disabilities (LD). Second, we attempted to identify how individual- and class-level characteristics moderated each intervention's effectiveness. We used multilevel random coefficient modeling to…

This article reviews research on the achievement outcomes of three types of approaches to improving elementary mathematics: mathematics curricula, computer-assisted instruction (CAI), and instructional process programs. Study inclusion requirements included use of a randomized or matched control group, a study duration of at least 12 weeks, and…

This article systematically reviews research on the achievement outcomes of four types of approaches to improving the reading success of children in the elementary grades: reading curricula, instructional technology, instructional process programs, and combinations of curricula and instructional process. Study inclusion criteria included use of…

Analysis of 326 studies of early intervention efficacy indicated significant positive benefits for most children but little evidence to support some common beliefs (such as the superiority of very early intervention or the necessity for parental involvement). Application of the steps in the scientific method are recommended for such large scale…

Meta-analysis was used to statistically integrate the findings of 30 studies of language intervention efficacy in mentally retarded preschool children. Results indicated that (1) intervention has positive, immediate gains for retarded children and that (2) significant neurological involvement may impede intervention success. (Author/DB)

Meta-Analysis of 59 studies revealed that neither the Frostig Developmental Test of Visual Perception nor the Frostig program for the development of visual perception was advantageous for handicapped students. (CL)

Meta-analysis was conducted on 31 evaluations of 15 government-sponsored training programs for disadvantaged groups, 1964-1998. Earnings effects were largest for women, modest for men, and negligible for youth. Skills training increased earnings; basic education was not effective. No evidence was found that more expensive programs performed…

Universal school-based programs to reduce or prevent violent behavior are delivered to all children in classrooms in a grade or in a school. Similarly, programs targeted to schools in high-risk areas (defined by low socioeconomic status or high crime rates) are delivered to all children in a grade or school in those high-risk areas. During…

Recent governments in the United Kingdom have introduced a number of initiatives aimed at improving the literacy levels of children. Policy and practice should be informed by rigorous evidence, and this evidence should be subjected to critical scrutiny. In the present paper the results of a "tertiary" review of systematic reviews in…

This report systematically reviews research on the outcomes of programs that teach young children in a group setting before they begin kindergarten. Study inclusion criteria included the use of randomized or matched control groups, evidence of initial equality, and study duration of at least 12 weeks. Studies included valid measures of language,…

This paper sets the scene for a collection of papers based on "The impact of policy on learning and inclusion in the learning and skills sector," a research project funded from January 2004 until July 2007 by the UK Economic and Social Research Council (ESRC) as part of their Teaching and Learning Research Programme (TLRP). We raise some…

A quantitative method, meta-analysis, is used to integrate research findings from a representative group of 38 coaching studies. Because different studies reported results on different scales, effect size was used to transform all results to a common metric. This meta-analysis showed that there are two distinct literatures on the effectiveness of…

This article describes conceptual and methodological limitations of existing research on the efficacy of early intervention programs. Recent studies using meta-analytic techniques to generate testable hypotheses are reviewed. Recommendations for greater precision in measurement and for improved research design are offered. (DB)

Results of three forms of meta-analysis on 41 studies involving behavior disorders revealed powerful effects of treatment: both interventions targeting classroom behavior and those attributable to a behavioral orientation were somewhat more powerful and robust. Methodological flaws, however, are cited. Recommendations for solidifying the research…

This article reviews 49 studies describing the use of differential reinforcement procedures to reduce maladaptive responding of persons with severe or profound mental retardation. Reviewed were the differential reinforcement of (1) alternative behavior; (2) low rates of responding; (3) other behavior; and (4) incompatible behavior. Findings were…
