This review examines 105 empirical studies that investigate students' views of the nature of science (VNOS), effects of curricular interventions on changing students' VNOS, and relations between VNOS and demographics, majors, and learning of science. The reviewed studies can be categorized into three theoretical frameworks: the unidimension, the…

This review examines the treatment integrity data of literacy interventions for students with emotional and/or behavioral disorders (EBD). Forty-four studies published between 1977 and 2005 were examined. Findings indicate that studies focusing on literacy interventions for students with EBD included clear operational definitions and data on…

Background: This meta-analysis of interventions with challenging behaviour in children with disabilities updates a comprehensive meta-analysis that previously addressed reported standards of practice and effectiveness of different strategies. Method: Four effect-size algorithms were calculated for published intervention cases, and results analysed…

The present meta-analysis examines the effect of grade retention on academic outcomes and investigates systemic sources of variability in effect sizes. Using multilevel modeling (MLM), the authors investigate characteristics of 207 effect sizes across 22 studies published between 1990 and 2007 at two levels: the study (between) and individual…

The last major review of the achievement outcomes of comprehensive school reform (CSR) models was conducted in 2003. Despite the growing evidence base supporting CSR, the program was discontinued by the federal government in 2007. Now, six years after the 2003 meta-analysis, the study's lead author, Geoffrey Borman, revisits the results and…

Meta-analytic procedures were used to test the effects of violent video games on aggressive behavior, aggressive cognition, aggressive affect, physiological arousal, empathy/desensitization, and prosocial behavior. Unique features of this meta-analytic review include (a) more restrictive methodological quality inclusion criteria than in past…

Prob,In this meta-analytic review, the authors summarized the effects of depression prevention programs for youth as well as investigated participant, intervention, provider, and research design features associated with larger effects. They identified 47 trials that evaluated 32 prevention programs, producing 60 intervention effect sizes. The…

The purpose of this article is to provide an overview of objective assessments of the short- and long-term outcomes of elementary school physical education programs. Evaluations have used a variety of designs, including longitudinal and tracking studies as well as correlational analyses. The short-term effect of physical education on health and…

This study examined the percentage of task-sampling variability in performance assessment via a meta-analysis. In total, 50 studies containing 130 independent data sets were analyzed. Overall results indicate that the percentage of variance for (a) differential difficulty of task was roughly 12% and (b) examinee's differential performance of the…

Critical thinking (CT), or the ability to engage in purposeful, self-regulatory judgment, is widely recognized as an important, even essential, skill. This article describes an ongoing meta-analysis that summarizes the available empirical evidence on the impact of instruction on the development and enhancement of critical thinking skills and…

The dominant literature on research synthesis methods has positivist and neo-positivist origins. In recent years, the landscape of research synthesis methods has changed rapidly to become inclusive. This article highlights methodologically inclusive advancements in research synthesis methods. Attention is drawn to insights from interpretive,…

Multisite research designs involving cluster randomization are becoming increasingly important in educational and behavioral research. Researchers would like to compute effect size indexes based on the standardized mean difference to compare the results of cluster-randomized studies (and corresponding quasi-experiments) with other studies and to…

This article takes a further look at the percentage of data points exceeding the median (PEM) analysis method for single-case research data, first presented in this journal by Hsen-Hsing Ma. Ma examined the relationship between PEM and the established percentage of nonoverlapping data (PND) and then applied PEM in a meta-analysis of 61 data sets,…

Methodological reviews have been used successfully to identify research trends and improve research practice in a variety of academic fields. Although there have been three methodological reviews of the emerging field of computer science education research, they lacked reliability or generalizability. Therefore, because of the capacity for a…

Background: Active Support (AS) is an approach for promoting increased engagement in activities by people with intellectual disability (ID). Method: We critically reviewed the available research on AS, and added a commentary to help guide future research and practice. Results: Despite weaknesses in the research design of some studies, there is…
