Research indicating many study results do not replicate has raised questions about the credibility of science and prompted concerns about a potential reproducibility crisis. Moreover, most published research is not freely accessible, which limits the potential impact of science. Open science, which aims to make the research process more open and…

Single-case design has a long history of use for assessing intervention effectiveness for children with disabilities. Although these designs have been widely employed for more than 50 years, recent years have been especially dynamic in terms of growth in the use of single-case design and application of standards designed to improve the validity…

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…

The purpose of this systematic review was to synthesize 22 single-case research design (SCRD) studies on social stories intervention for individuals with autism spectrum disorder (ASD). We used the What Works Clearinghouse (WWC) SCRD standards to analyze study rigor and evidence of a causal relation. We calculated four nonoverlap indices to…

Identifying potentially effective practices for improving outcomes for individuals with autism spectrum disorder (ASD) is a complex process. In this article, we respond to recent reviews of evidence-based practices for individuals with ASD. We identify possible problems and make suggestions in relation to identifying well-specified practices,…

Research in early intervention/early childhood special education (EI/ECSE) is focused on identifying effective practices related to positive outcomes for young children with disabilities and their families. Individual responses to evidence-based practices are often variable, and non-responders are common. Single case research (SCR) might be…

Autism spectrum disorder (ASD) occurs in all racial, ethnic, and socioeconomic groups; however, children from culturally and linguistically diverse groups are, on average, misdiagnosed more often and identified later than White children. Understanding current practices and procedures is important for ensuring the use of evidence-based…

The Pyramid Model for Supporting Social Emotional Competence in Infants and Young Children (Hemmeter, Fox, & Snyder, 2013), or the Pyramid Model, is a conceptual framework focused on systemic and sustained implementation of evidence-based practices (EBP) related to promoting social emotional competence and preventing challenging behaviors in…

The adoption of methods and strategies validated through rigorous, experimentally oriented research is a core professional value of special education. We conducted a systematic review and meta-analysis examining the experimental literature on Technology-Aided Instruction and Intervention (TAII) using research identified as part of the National…

Inclusion is clearly related to better outcomes for young children--but reports from the US Department of Education show the practice has grown by just 5% over the past 27 years. This is the how-to book preschool administrators, school district leaders, child care directors, and faculty need to step up the progress of early childhood inclusion…

Although comparison studies are important in early intervention/early childhood special education (EI/ECSE), results of well-designed comparison studies are likely to be unpublished because of undifferentiated or differently differentiated results across participants. The purpose of this article is to highlight the utility of comparison designs in…
