Measures of socioeconomic status (SES) are routinely used in analyses of achievement data to increase statistical power, statistically control for the effects of SES, and enhance causality arguments under the premise that the SES-achievement relationship is moderate to strong. Empirical evidence characterizing the strength of the SES-achievement…

This article presents a meta-analytic review of the relation between executive function and reading comprehension. Results (N = 6,673) supported a moderate positive association between executive function and reading comprehension (r = 0.36). Moderator analyses suggested that correlations between executive function and reading comprehension did not…

A growing body of evidence points to the common co-occurrence of language and behavioral difficulties in children. Primary studies often focus on this relation in children with identified deficits. However, it is unknown whether this relation holds across other children at risk or representative samples of children or over time. The purpose of…

This article is intended to synthesize the broader literature investigating the effectiveness and salient features of interventions designed to enhance the social competence of youth and adults with autism spectrum disorder. Outcomes for adults with autism spectrum disorder remain poor with only minimal improvement shown for decades. Among 796…

Using meta-analysis, this study examines the effect of computer-supported education on students' attitudes and determines the degree to which the effect size obtained by combining the effect sizes of various studies differs, in terms of educational level, course subjects and application duration. Based on the inclusion criteria, a total of 32…

The main purpose of this study was to determine the effect of homework assignments on students' academic achievement. This meta-analysis sought an answer to the research question: "What kind of effect does homework assignment have on students' academic achievement levels?" In this research, meta-analysis was adopted to determine the…

Current approaches to gifted identification suggest collecting multiple sources of evidence. Some gifted identification guidelines allow for the interchangeable use of "performance" and "nonperformance" identification methods. This multiple criteria approach lacks a strong overlap between the assessment tools; however,…

The purpose of this study is to test the effect of educational leadership on some organizational variables using meta-analysis method. In this context, the results of independent researches were merged together and the hypotheses created within the scope of the study were tested. In order to determine the researches to be included in the study,…

The ability to use language effectively in communication is regarded as important as knowledge of grammatical rules in the communicative competence models. Pragmatic competence, namely the ability to understand and use linguistic forms appropriately according to context, is thus accepted as a vital component of language ability. Recently,…

Over the past decade, the number of one-to-one laptop programs in schools has steadily increased. Despite the growth of such programs, there is little consensus about whether they contribute to improved educational outcomes. This article reviews 65 journal articles and 31 doctoral dissertations published from January 2001 to May 2015 to examine…

This article systematically reviews what is known empirically about the association between executive function and student achievement in both reading and math and critically assesses the evidence for a causal association between the two. Using meta-analytic techniques, the review finds that there is a moderate unconditional association between…

The current study employed a meta-analytic approach to investigate the relative importance of component reading skills to reading comprehension in struggling adult readers. A total of 10 component skills were consistently identified across 16 independent studies and 2,707 participants. Random effects models generated 76 predictor-reading…

Students with disabilities experience poorer post-school outcomes compared with their peers without disabilities. Existing experimental literature on "what works" for improving these outcomes is rare; however, a rapidly growing body of research investigates correlational relationships between experiences in school and post-school…

Many studies of school achievement find a significant association between reading and arithmetic achievement. The magnitude of the association varies widely across the studies, but the sources of this variation have not been identified. The purpose of this paper is to examine the magnitude and determinants of the relation between arithmetic and…

The finding that academic summer programs are effective for low income students has been replicated across meta-analytic reviews. However, these reviews have yielded contradictory evidence about whether summer programs are more effective for lower- or higher-income students. This discrepancy may be due to income-based differences in the summer…
