Introduction: Missing data are bound to occur in education intervention research. Reasons vary but always have the consequence of reducing sample sizes and can, under certain conditions, seriously bias estimated intervention effects. A wide array of methods have been developed for handling missing data (Enders, 2023). Whereas older approaches…

Mathematical problem posing, generally defined as the process of interpreting given situations and formulating meaningful mathematical problems, is academically important, and thus several interventions have been used to enhance this competence among students and teachers. Yet little is known about the interventions' various components and their…

Cluster randomized trials (CRTs) are commonly used to evaluate the causal effects of educational interventions, where the entire clusters (e.g., schools) are randomly assigned to treatment or control conditions. This study introduces statistical methods for designing and analyzing two-level (e.g., students nested within schools) and three-level…

A number of resources are available for evaluating the rigor of single-case designs, including the commonly used multiple baseline design. In this article, we discuss two characteristics commonly cited as necessary for the highest rigor in multiple baseline designs--concurrence and response-guided baseline condition duration. We suggest that both…

The Campbellian validity typology has been used as a foundation for outcome evaluation and for developing evidence-based interventions for decades. As such, randomized control trials were preferred for outcome evaluation. However, some evaluators disagree with the validity typology's argument that randomized controlled trials as the best design…

Intensive academic interventions help address the learning difficulties of students with specific learning disabilities (SLDs). Challenging behaviors exhibited during instruction can have a negative impact on the overall effectiveness of an academic intervention. In addition to academic interventions, students with SLD may benefit from behavioral…

The purpose of this study is to present a set of empirically derived effect size distributions in order to provide field-based benchmarks for assessing the relative effects of interventions aimed at reducing challenging behavior or increasing engagement for young children with and without disabilities. We synthesized 192 single-case designs that…

Inappropriate behavior on school buses is a safety issue that concerns students, parents, and educators. There is potential for traffic-related injury, and the limited adult supervision on school buses often facilitates bullying and other infractions. This review identified peer-reviewed articles and dissertations evaluating behavioral…

The brain undergoes profound development across childhood and adolescence, including continuous changes in brain morphology, connectivity, and functioning that are, in part, dependent on one's experiences. These neurobiological changes are accompanied by significant changes in children's and adolescents' cognitive learning. By drawing from studies…

David Berliner argued in 2002 that educational research is the hardest science of all. His arguments addressed the complexity that context plays in educational settings and the difficulties of applying research designs that were largely developed and refined in the natural sciences arena to fields of human behavior. In this article, it is argued…

Identifying mathematical interventions that practitioners can implement to improve the mathematical problem solving (PS) of students is a need for the field. Literature on the PS performance of students with disabilities has grown; recently, schema instruction (SI) has been suggested as an evidence-based practice. The purpose of this study was to…

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,…

Over the past 15 years, we have seen an increase in the use of cluster randomized trials (CRTs) to test the efficacy of educational interventions. These studies are often designed with the goal of determining whether a program works, or answering the what works question. Recently, the goals of these studies expanded to include for whom and under…

Conducting intervention studies with homeless populations can be difficult, particularly in terms of retaining participants across multiple sessions and locating them for subsequent follow-up assessments. Homeless youth are even more challenging to engage due to substance use, mental health problems, wariness of authority figures, and frequent…

Given the importance of social integration and participation in inclusive settings for young children with autism spectrum disorder (ASD), the purpose of this systematic review was to examine instructional outcomes and participant, teacher, group, and instructional characteristics that may be pertinent to successful group instruction for young…
