We estimated effects of writing interventions on the level and trend of writing fluency--rate of total words written over time--by students with and without disabilities. Using mixed-effects regression and an information-theoretic ranking of competing models, we synthesized results of 42 single-case experimental design studies with a total of 205…

The success of teachers is tied to their effectiveness in managing student behavior. In this meta-analysis, we identified 49 single-case-design studies that evaluated the effectiveness of teacher training on their implementation of behavioral support strategies. Training was most often provided in a one-on-one format (n = 18) and included ongoing…

High-quality systematic literature reviews provide a systematic process for identifying, synthesizing, and critiquing multiple studies and, in turn, inform theory, research, practice, and policy. With a focus on special education systematic reviews, we propose four core principles (i.e., coherence, contextualization, generativity, and…

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…

Researchers and practitioners alike often look to meta-analyses to identify effective practices to use with students with disabilities. The number of meta-analyses in special education has also expanded in recent years. The purpose of this systematic review is to evaluate the quality of reporting in meta-analyses focused on mathematics…

Publication bias involves the disproportionate representation of studies with large and significant effects in the published research. Among other problems, publication bias results in inflated omnibus effect sizes in meta-analyses, giving the impression that interventions have stronger effects than they actually do. Although evidence suggests…

Empirical studies investigating supplemental reading interventions for students with or at risk for reading disabilities in the early elementary grades have demonstrated a range of effect sizes. Identifying the findings from high-quality research can provide greater certainty of findings related to the effectiveness of supplemental reading…

Existing reviews address important questions about subsets of practitioner training studies in special education but leave important questions about the broader literature unanswered. In this comprehensive review, we identified 118 peer-reviewed single-case-design studies in which researchers tested the efficacy of practitioner training on…

This meta-analysis is the first to provide a quantitative synthesis of empirical evaluations of mathematical intervention programs implemented in secondary schools for students with learning disabilities and mathematics difficulties. Included studies used a treatment-control group design. A total of 19 experimental and quasi-experimental studies…

There is a general consensus that writing is a challenging task for students with learning disabilities (LD). To identify more precisely the extent and depth of the challenges that these students experience with writing, the authors conducted a meta-analysis comparing the writing performance of students with LD to their typically achieving peers.…

The daily report card (DRC) is a commonly employed behavioral intervention for treating attention deficit hyperactivity disorder (ADHD) in schools. Much of the support for the DRC comes from single-case studies, which have traditionally received less attention than group studies. This lack of attention to single-case studies results in an…

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…

Low language proficiency and problem behavior often co-occur, yet language deficits are likely to be overlooked in children with emotional and behavioral disorders (EBD). Random effects meta-analyses were conducted to determine prevalence and severity of the problem. Across 22 studies, participants included 1,171 children ages 5-13 with formally…

Findings from a meta-analysis of 26 studies investigating the effects of either the "Kids on the Block" or "Count Me In" puppet shows on changes in elementary students' attitudes toward and knowledge of individuals with disabilities are reported. The studies included 5,302 intervention group participants and 2,642…

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…
