The purpose of this meta-analysis was to examine the effectiveness of early numeracy interventions for young students, including students with disabilities or those at-risk for mathematics difficulty (MD). This study evaluated preschool, kindergarten, and first-grade interventions on early numeracy content, instructional features, and…

In this meta-analysis of 45 studies involving students in grades 2-12, the authors present evidence on the effects of text structure instruction on the expository reading comprehension of students. The meta-analysis was deigned to answer two sets of questions. The first set of questions examined the effectiveness of text structure instruction on…

Computer-assisted instruction (CAI) for students with disabilities can be categorized into the following categories: visual, auditory, mobile, and cognitive skills-based CAI. Cognitive-skills based CAI differs from other types of CAI largely in terms of an emphasis on instructional design features. We conducted both systematic review of…

The need for global competence in mathematics is apparent. Algebra is considered a gateway course to prepare students for the demands of a competitive global market. Many students demonstrate low performance in algebra; this is especially true for students with disabilities. Effective algebra instruction is essential to increase algebra…

The authors completed a narrative review of studies of mathematics interventions from 1996 to 2010 for helping elementary school students with difficulties in mathematics solve word problems. Key instructional components supported by research are teaching cognitive and metacognitive skills; schema-based instruction focusing on semantic analysis,…

This paper synthesizes the findings of social skills interventions conducted with 3- to 5-year-old children with disabilities between 1975 and 1999. Provided are study purposes, procedures, measures, and findings as well as analysis of effect size outcomes. Positive outcomes were associated with a range of interventions, including modeling,…

Studies (N=25) of the effectiveness of Direct Instruction programs with special education students were examined in a meta-analysis comparison. None of the studies showed results favoring comparison groups. Fifty-three percent of the outcomes significantly favored Direct Instruction. Effects were not restricted to particular handicapping…

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)

The article critiques a 1987 (Kavale and Forness) meta-analysis which concluded that research does not support modality-based instruction. The study is faulted for its selection criteria as well as its failure to consider demographic differences, achievement level differences, multiplicity of preferences, definitions of terms, effect-size…

This response to Dunn (EC 221 793) reaffirms the conclusions of a meta analysis on modality-based instruction, through elaboration of the study's selection criteria and methodological factors. Although modality-based instruction is seen to be intuitively appealing, educators are encouraged, instead, to apply instructional methods of proven…

This study used meta-analyses to evaluate the relative effectiveness of a variety of educational interventions with students who have disabilities. A graph of average effect sizes for 18 interventions shows the demonstrated effectiveness of mnemonic training, reading comprehension instruction, behavior modification, direct instruction,…

This article discusses probable explanations for the weak effects in some meta-analyses that have investigated the effectiveness of social skills training (SST) for students with disabilities and offers specific recommendations for designing and producing more effective SST interventions. Treatment integrity issues, assessment issues, and…

This paper reviews 31 studies which directly compared two or more instructional strategies used with students who display moderate to severe handicaps. The efficiency and effectiveness of 13 strategies are reported, including error manipulation strategies, response prompting strategies, naturalistic teaching strategies, and stimulus modification…

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…
