Children with learning difficulties suffer from working memory (WM) deficits. Yet the specificity of deficits associated with different types of learning difficulties remains unclear. Further research can contribute to our understanding of the nature of WM and the relationship between it and learning difficulties. The current meta-analysis…

In this article, the authors consider the power and limitations of responsiveness-to-intervention (RTI) for reducing the need for ongoing and intensive services for the segment of the school population traditionally identified as having a learning disability in mathematics. To assess the robustness of RTI, the authors describe four studies with…

The meta-analysis investigated the effects on achievement of type of graphing paper employed in displaying student performance data collected over time based on 15 controlled studies with 16 effect sizes. No significant differences in student achievement were found between studies using six-cycle and studies using equal interval paper graphing…

The meta analysis explored how measuring special education student progress toward long-term vs. short-term goals affects achievement outcomes. Results indicated that when progress toward long-term goals was measured, unbiased effect sizes were higher than on probelike outcomes; when progress toward short-term goals was measured, the reverse was…

There is increasingly negative sentiment against IQ-achievement discrepancy as a method to identify children with learning disabilities (LD) and, more broadly, intelligence as an explanation of poor academic performance. The evidence for this latter view was examined by reviewing 13 studies involving 1,542 children who were at risk or reading…

Presented is a quantitative synthesis of examiner familiarity effects on Caucasian and minority students' test performance. Fourteen controlled studies were coded in terms of methodological quality and race-ethnicity. Caucasian students performed similarly in both familiar and unfamiliar examiner conditions, while Black and Hispanic children…

A meta-analysis of 79 studies of reading performance of low achievers with and without learning disabilities found students with the learning disabilities label performed considerably worse on reading measures. Use of timed tests greatly increased the difference in reading performance between underachievers and students with the learning…

This meta-analysis investigated the effects of formative evaluation procedures on student achievement. Twenty-one controlled studies generated 96 relevant effect sizes (average weighted effect size .70). Magnitude of effect of formative evaluation was associated with publication type, data-evaluation method, data display, and use of behavior…

This article reviews 15 research studies published from 1990 to 2000 examining effects of cooperative learning strategies on the academic achievement of students with learning disabilities. Despite design problems, the review finds that cooperative learning strategies that incorporate individual accountability and group rewards are likely to…

Based on data from 22 controlled studies, this article presents a meta-analysis of the effects of examiner familiarity on children's test performance. It was found that examiner familiarity raised scores especially when subjects were: (1) of low socioeconomic status; (2) tested on difficult tests; and (3) knew the examiner for a long duration.…
