Single-case comparative studies could help identify efficient instructional procedures for individuals with disabilities. However, previous literature reported inconsistent efficiency results if multiple comparisons were conducted, indicating that within-participant replication was uncommon. In this review, we examined single-case comparative…

This review aimed to analyze the psychometric properties of standardized instruments that are used to measure pragmatic intervention effects in children with developmental language disorder. Following PRISMA structure, a comprehensive literature research was conducted in five electronic indexing databases: Central, PubMed, Medline, Web of Science…

Special education teachers' (SETs) working conditions play a crucial role in shaping the size, quality, and effectiveness of the U.S. SET workforce and thereby shape the quality of instruction provided to students with disabilities. Valid measures of SETs' working conditions are essential for conducting robust research on how to improve working…

Classroom observation research plays an important role in policy, practice, and scholarship for students with disabilities. When interpreting results of observation studies, it is important to consider the validity evidence provided by researchers and how that speaks to the intended use of those results. In this literature synthesis, we used…

This study examines how well in-service teachers in Hong Kong (N = 1,110) are supported in their efforts to teach in inclusive classrooms. It also examines the psychometric properties of the newly developed Teachers' Perceived Support Needs scale to measure in-service teachers' perceived support needs. Factors that predict teachers' perceived…

Single-case research design is a useful methodology for evaluating the presence of a functional relation between an intervention and the mathematical performance of students with a learning disability. However, a functional relation cannot be established with threats to internal validity of the design. External validity is impacted if researchers…

Representations of disabled students -- by both disabled and abled people -- are vital to disabled futures because they hold important implications for how abled people conceive of, and thereby support, disabled students. For years, scholarship on disability in postsecondary education has failed to interrogate the problematic narratives…

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,…

In this report, we summarize research on the identification of SLD and make recommendations for practice. The report begins with a summary of the legal requirements for SLD identification and what constitutes a comprehensive evaluation. It then discusses the attributes of SLD according to different conceptual frameworks and reviews research on the…

The purpose of this report is to present a synthesis of the research on test accommodations published in 2015 and 2016. We summarize the research to review current research trends and enhance understanding of the implications of accommodations use in the development of future policy directions, to highlight implementation of current and new…
