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…

Randomized experiments are a strong design for establishing impact evidence because the random assignment mechanism theoretically allows confidence in attributing group differences to the intervention. Growth of randomized experiments within educational studies has been widely documented. However, randomized experiments within education have…

Introduction: The What Works Clearinghouse (WWC) reviews rigorous research on educational interventions with a goal of identifying "what works" and making that information accessible to educators and policymakers. In rating the quality of causal research, the WWC has historically prioritized internal validity over external validity. One…

Introduction: Concerns about the risk of bias (RoB) of Meta-analysis (MAs) have grown in parallel with the exponential increase in the number of publications in science. However, this has not been properly assessed in Education. The aims were to evaluate the RoB of MAs in Education and to identify potential predictors of a lower RoB. Methods:…

In this article John Raven responds to commentaries on his article, "Diving in Where Angels Fear to Tread: Pre-Requisites to Evidence-Based Interventions" (EJ1248321). Herein, he provides dialogues with individual authors that relate closely to his original theme and which seemed to merit further elaboration. He briefly addresses: (1)…

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…

Randomized controlled trials have proliferated in education, in part because they provide an unbiased estimator for the causal impact of interventions. It is increasingly recognized that many such trials in education have low power to detect an effect if indeed there is one. However, it is less well known that low powered trials tend to…

There are marked racial and ethnic disparities in diagnosis and services for individuals on the autism spectrum, yet race and ethnicity are underreported and underexamined in autism research. The current study examines the reporting of race and ethnicity and the inclusion of participants across racial and ethnic groups in studies included in a…

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…

In John Raven's "Diving in Where Angels Fear to Tread: Pre-Requisites to Evidence-Based Interventions," he outlines several critical failings in which social scientists bear a responsibility for potentially a great deal of damage toward children, society, and notably, the planet itself. The nature of the damage appears to be one of…

Evidence-based education aims to support policy makers choosing between potential interventions. This rarely involves considering each in isolation; instead, sets of evidence regarding many potential policy interventions are considered. Filtering a set on any quantity measured with error risks the "winner's curse": conditional on…

In this commentary on John Raven's "Diving in Where Angels Fear to Tread: Pre-Requisites to Evidence-Based Interventions," Tommy MacKay discusses three examples that illustrate Raven's tendency to overstate or at least to over-simplify the issues raised in his paper and to present various views, approaches, or interventions as being…

Missing data are ubiquitous in studies examining preventive interventions. This missing data need to be handled appropriately for data analyses to yield unbiased results. After a brief discussion of missing data mechanisms, inappropriate missing data treatments and appropriate missing data treatments, we review the current state of missing data…

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…

Background: Interventions for offenders with intellectual disabilities (ID) have used cognitive variables as measures of treatment outcome. However, the relevance of cognitive variables to offending in people with intellectual disabilities is unclear. This review aimed to evaluate the evidence for a relationship between cognitive variables and…
