Systematic reviews of single-case experimental research (SCER) in special education often use the What Works Clearinghouse (WWC) Standards to assess the methodological rigor of studies within a given literature base. While significant changes were made between the two most recent versions of the WWC standards, no research to date has evaluated the…

In this systematic evaluation of intervention research for transition-age autistic youth, we examined quality indicators in 193 group and single-case design intervention studies, which tested effects on 1258 outcomes. Behaviorally based interventions were the most common intervention type. We found significant threats to internal validity for the…

Research syntheses that evaluate bilingual program effectiveness have grown exponentially since the 1980s. Contradictory to earlier anti-bilingual findings, these research syntheses, including statistical meta-analyses, have converged on findings supporting L1 teaching. This study examines the methodological soundness of eight statistical…

This study examines concepts surrounding the quality of afterschool programs in Japan and related challenges using qualitative and quantitative methods. A content analysis of government guidelines for afterschool programs provided by the Ministry of Health, Labour and Welfare (MHLW) and the Ministry of Education, Culture, Sports, Science and…

Technology has been widely used to teach reading skills to students with autism spectrum disorder (ASD), but the quality of research backing up this practice has not yet been fully investigated. The purpose of this review was to examine the quality of research on technology-aided reading interventions for students with ASD and summarize study…

Educators and researchers are increasingly interested in evaluating and promoting socio-emotional learning (SEL) beginning in early childhood (Newman & Dusunbury in 2015; Zigler & Trickett in American Psychologist 33(9):789-798 https://doi.org/10.1037/0003-066X.33.9.789, 1978). Decades of research have linked participation in high-quality…

Education decisionmakers need access to the best evidence about the effectiveness of education interventions, including practices, products, programs, and policies. It can be difficult, time consuming, and costly to access and draw conclusions from relevant studies about the effectiveness of interventions. The What Works Clearinghouse (WWC)…

Positive Behaviour Support is an applied behaviour analytic system of support that is utilised in schools and in residential care settings for children and adults with disabilities who engage in challenging behaviour. Implementation fidelity depends on appropriate staff training and organisational behaviour management. A systematic literature…

Programs that improve teaching effectiveness represent a core strategy to improve student educational outcomes and close student achievement gaps. This article compiles empirical values of intraclass correlations for designing effective and efficient experimental studies evaluating the effects of these programs. The Early Childhood Longitudinal…

This project seeks to answer questions about the effectiveness of early childhood programs in meeting their important goals, paying careful attention to the effectiveness of program variations (especially in regard to particular demographic and economic target groups). This review will be guided by two overarching questions: (1) How effective are…

The major aim of this manuscript is to bring together two important topics that have recently received much attention in child and adolescent research, albeit separately from each other: single-case experimental designs and statistical mediation analysis. Single-case experimental designs (SCEDs) are increasingly recognized as a valuable…

Governments and private funders are placing increasing demands on postsecondary institutions and community-based organizations to account for the impacts from their collaborative research and learning efforts. In this article, we explore how best to account for impacts arising from the Community First: Impacts of Community Engagement project…

This tool is designed for individuals who want to formatively assess a research-practice partnership (RPP) in collaboration with its members. It provides guidance on how to set and monitor progress on quarterly RPP goals aligned to five critical dimensions that researchers and practitioners must address to build and sustain an effective RPP. This…

More aggregate data on school performance is available than ever before, opening up new possibilities for applied researchers interested in assessing the effectiveness of school-level interventions quickly and at a relatively low cost by implementing comparative interrupted times series (CITS) designs. We examine the extent to which effect…

Introduction: Rating the quality of a body of evidence is an increasingly common component of research syntheses on intervention effectiveness. This study sought to identify and examine existing systems for rating the quality of a body of evidence on the effectiveness of health and social interventions. Methods: We used a multicomponent search…
