This study aims to introduce network meta-analysis (NMA) to provide educational researchers with an extended view of the reviewing educational research. Meta-analytic methods have been widely used in educational research reviews. However, weaknesses have emerged in the multi-group comparison analysis of educational studies where different…

Comparison studies conducted to determine which instructional interventions are most efficient for teaching discrete behaviors to individuals with disabilities are potentially valuable, although some threats to internal validity may be more likely in these studies. Studies included in this review typically met common internal validity standards,…

Randomization of large number of participants to different treatment groups is often not a feasible or preferable way to answer questions of immediate interest to professional practice. Single case designs (SCDs) are a class of research designs that are experimental in nature but require only a few participants, all of whom receive the…

Researchers are often interested in whether the effects of an intervention differ conditional on individual- or group-moderator variables such as children's characteristics (e.g., gender), teacher's background (e.g., years of teaching), and school's characteristics (e.g., urbanity); that is, the researchers seek to examine for whom and under what…

Tools for evaluating the quality and rigor of single case research designs (SCD) are often used when conducting SCD syntheses. Preferred components include evaluations of design features related to the internal validity of SCD to obtain quality and/or rigor ratings. Three tools for evaluating the quality and rigor of SCD (Council for Exceptional…

Communicating with peers often poses challenges for individuals with autism spectrum disorder (ASD); these social interactions, however, can be especially difficult during the teenage years. For many adolescents with ASD, peer interaction is often limited or nonexistent, even for those taught in general education settings. The purpose of this…

Varying methods for evaluating the outcomes of single case research designs (SCD) are currently used in reviews and meta-analyses of interventions. Quantitative effect size measures are often presented alongside visual analysis conclusions. Six measures across two classes--overlap measures (percentage non-overlapping data, improvement rate…

Valid and evidence-informed practices are critical to help young children with disabilities and their families with highly effective interventions and instruction to reach their potentials. Replication research is critical for appraising research and identifying evidence-based practices. The purpose of this study was to replicate the methods used…

Taped problems is an intervention strategy for addressing mathematics fluency that has been evaluated in multiple single-case design studies. Although its efficacy has been supported in individual studies, no comprehensive quantitative synthesis has been conducted on taped problems. The purpose of this study was to synthesize the literature that…

When examining the evidence on therapeutic interventions to answer a comparative effectiveness research question, one should consider all studies that are informative on the interventions' causal effects. "Single group studies" evaluate outcomes longitudinally in cohorts of subjects who are managed with a single treatment strategy.…

With so many students attending summer programs, it is remarkable that there is little research available aiming to investigate achievement differences in participants versus non-participants. This study examined the place of a summer program within a school district budget and curriculum. The study was designed to better understand the…

Despite poor vocabulary outcomes for children with hearing loss, few studies have evaluated the effectiveness of specific vocabulary teaching methods on vocabulary learning for this group. The authors compared three vocabulary instruction conditions with preschool children with hearing loss: (a) explicit, direct instruction; (b) follow-in…

This review protocol from the What Works Clearinghouse (WWC) covers the following issues relevant to screening criteria and full review for the Access to Higher Education Practice Guide: (1) time frame; (2) study design; (3) age and/or grade range; (4) brief description of intervention; (5) key subgroups; (6) location and language; (7) outcomes…

Sexual violence on college campuses is a pervasive problem with the potential for extensive physical and psychological health consequences. Institutions have begun implementing prevention programs; however, more research is needed to understand whether these programs are effective. Bystander intervention programs have increased in popularity…

The purpose of this investigation was to explore whether a difference existed between the effectiveness of paper-based format and tablet computer-based format Social Story interventions on frequency of undesired behaviors. An adapted alternating treatment design was implemented with four children with autism spectrum disorder (ASD). Data regarding…
