To determine whether formative writing assessments that are directly tied to everyday classroom teaching and learning enhance students' writing performance, we conducted a meta-analysis of true and quasi-experiments conducted with students in grades 1 to 8. We found that feedback to students about writing from adults, peers, self, and computers…

This article synthesizes the experimental literature on reading interventions for upper elementary and middle school students identified with reading disabilities on norm-referenced reading measures. Ten studies (12 independent samples) yielded 70 effect sizes on norm-referenced reading measures with an aggregated mean of 0.41 (SE = 0.04) in favor…

This meta-analysis examined school-based intervention research based on functional behavioral assessment (FBA) to determine the effectiveness of key individualized positive behavior support (IPBS) practices in school settings. In all, 83 studies representing 145 participants were included in the meta-analysis. Intervention, maintenance, and…

This investigation used meta-analytic techniques to evaluate the effectiveness of school-based prevention programming in reducing cannabis use among youth aged 12 to 19. It summarized the results from 15 studies published in peer-reviewed journals since 1999 and identified features that influenced program effectiveness. The results from the set of…

The purpose of this study is to examine the effects of morphological instruction on language and literacy outcomes by synthesizing 92 standardized mean differences (d) from 30 independent studies. Findings show a moderate overall effect of morphological instruction ([d-bar] = 0.32), suggesting that children receiving morphological instruction…

Within the literature there has been a call for the integration of science, technology, engineering, and mathematics (STEM) disciplines. Little research has been conducted to investigate the effects of integrative approaches among STEM subjects. The purpose of this study was to synthesize findings from existing research on the effects of…

This meta-analysis examines the effectiveness of a group of instructional approaches (i.e., cooperative, collaborative, and peer tutoring) at improving literacy outcomes for English language learners. Main effects analyses of a sample of 28 experimental and quasi-experimental studies reveal that peer-mediation is more effective for ELLs than…

Dynamic geometry software (DGS) aims to enhance mathematics education. This systematic review and meta-analysis evaluated the quasi-experimental studies on the effectiveness of DGS-based instruction in improving students' mathematical achievement. Research articles published between 1990 and 2013 were identified from major databases according to a…

Objectives: To evaluate the impact of school-based mentoring for adolescents (11-18 years) on academic performance, attendance, attitudes, behavior, and self-esteem. Method: A systematic review and meta-analysis. The authors searched 12 databases from 1980 to 2011. Eight studies with 6,072 participants were included, 6 were included in…

States are increasingly interested in including measures of student achievement growth, or "value- added," in evaluating teachers. Annual state assessments, however, which are the typical measure of student growth, usually cover only reading and math teachers and only in grades 4-8. These state assessments thus cannot …

States and school districts are exploring alternatives to state tests for measuring teachers' contributions to student learning. One approach applies statistical value-added methods to alternative student assessments such as commercially available tests and end-of course tests. The evidence suggests that these methods can reliably distinguish…

A vertical scale, in principle, provides a common metric across tests with differing difficulties (e.g., spanning multiple grades) so that statements of "absolute" growth can be made. This paper compares 16 states' 2007-2008 effect size growth trends on vertically scaled reading and math assessments across grades 3 to 8. Two patterns…

A meta-analysis of the relationship between attitudes in reading and achievement in reading was conducted to provide a statistical summary to the observed variability in the magnitude of previously reported effect sizes. A total of 32 studies, with a total sample size of 224,615 were used, and included a total of 118 effect sizes. A multi-level…

Background/Context: Within the context of four locally funded research projects, the researcher was asked to disseminate the findings of her narrative inquiries not to the research community, which had previously been the case, but to the practice and philanthropic communities. This, in turn, created a representational crisis because practitioners…

This meta-analysis reviewed the effect of practical reasoning instruction (PRI) on student outcome in Home Economics education in Korea. In this meta-analysis, 25 studies with 35 effect sizes were analyzed. The results of this review indicated that PRI is more effective than traditional instruction on student outcomes. A medium and significant…
