Informed by theories of reading comprehension and prior reviews of reading comprehension intervention, this meta-analysis uniquely contributes to the literature because it describes the relative effects of various approaches to comprehension intervention for struggling readers in Grades 3 through 12. Findings from 64 studies demonstrate…

Over the past decade, parent advocacy groups led a grassroots movement resulting in most states adopting dyslexia-specific legislation, with many states mandating the use of the Orton-Gillingham approach to reading instruction. Orton-Gillingham is a direct, explicit, multisensory, structured, sequential, diagnostic, and prescriptive approach to…

This meta-analysis examined the effectiveness of supplemental Tier-2 mathematics interventions for students with mathematics difficulties (MD). We reviewed 39 experimental and quasi-experimental studies that included 40 independent samples, with 61 treatment groups. Utilizing robust variance estimation (RVE), results revealed a treatment effect of…

This meta-analysis synthesized over 40 years of research (k = 42 studies) in the social studies for students with learning disabilities. We analyzed the various mechanisms that researchers have used to improve outcomes in the social studies by conducting a subgroup investigation of interventions targeting the following instructional categories:…

Educators need evidence-based practices to assist students with disabilities in meeting increasingly rigorous standards in mathematics. Students with autism spectrum disorder (ASD) are increasingly expected to demonstrate learning of basic and advanced mathematical concepts. This review identifies math intervention studies involving children and…

Optimal levels of treatment fidelity, a critical moderator of intervention effectiveness, are often difficult to sustain in applied settings. It is unknown whether performance feedback, a widely researched method for increasing educators' treatment fidelity, is an evidence-based practice. The purpose of this review was to evaluate the current…

Self-management interventions aimed at skill acquisition and/or improving behavior of students diagnosed with autism spectrum disorders were examined. Twenty-three single-subject research design studies met inclusion criteria. Quality assessment of these studies was conducted using the What Works Clearinghouse guidelines, and treatment effect…

Interventions based on the results of functional behavioral assessment (FBA) have been the topic of extensive research and, in certain cases, mandated for students with disabilities under the Individuals With Disabilities Education Act. There exist a wide variety of methods for conducting such assessments, with little consensus in the field. The…

In this meta-analysis, the impact of writing interventions on the quality of writing produced by students with learning disabilities (LD) was assessed. Ancestral and electronic searches were used to locate experimental, quasi-experimental, and within-subjects design studies with participants in Grades 1-12 with documented LD. The effects of…

A review of traditional (such as psychotherapy) and behavioral approaches (such as self-monitoring and reinforcement) to obesity treatment of mentally retarded students led to the conclusion that the behavioral orientation was more successful. Implications for initiating such programs include thorough training, voluntary participation, and parent…

The article demonstrates that use of meta-analysis on studies investigating the effectiveness of psycholingistic training with handicapped children results in nonvalidation of the training--a conclusion which contradicts results reported earlier by K. Kavale. (SW)

The article summarized the current literature on therapeutic camping, including the nature of existing programs (such as the wilderness camp), rationales for the superiority of camping as a therapeutic program, and evaluation of existing programs for treatment of the emotionally disturbed child.

The role of archival data in planning intervention priorities is examined and efficacy research focusing on the three types of positive behavioral support (PBS) is evaluated: schoolwide (universal), specific setting, and individual student levels. Overall, findings were positive across all types of PBS, validating implementation of these…

This paper cites modest beneficial effects of early intervention for children with developmental disabilities or children at risk, and examines two specific program features, age of start and family involvement. The moderating influence of the level of disability severity is also analyzed, and future directions for improving early intervention…

A review of the literature on Individualized Education Programs (IEPs) from 1975 to 1989 identifies three phases (a normative phase, an analytic phase, and a technology reaction phase), and reveals a history of IEPs' inadequacies and passive compliance, in contrast to the original intent of Public Law 94-142.
