Word problem-solving (WPS) poses a significant challenge for many students, particularly those with mathematics difficulties (MD), hindering their overall mathematical development. To improve WPS proficiency, providing individualized and intensive interventions is critical. This umbrella review examined 11 medium- to high-quality meta-analyses to…

English learner (EL) students are a heterogeneous group with unique needs and the challenges of acquiring a new language while also learning grade-level academic content. Math word problems pose a challenge for some EL students who are at risk for math disabilities. This study, conducted by myself and H. Lee Swanson, used a single-case research…

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…

The efficacy of mathematics interventions for students with mathematics difficulties is a critical concern in educational research, particularly in light of the increasing demand for effective instructional strategies. While previous meta-analyses have explored various aspects of mathematics interventions, our study uniquely focuses on a broad…

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)…

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…

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…

This paper is a systematic literature review of works focused on user-centred design practices and their potential application in pedagogical contexts in design and technology (D&T) education. It is a response to the increasingly complex demand of allowing students to develop so-called 21st-century skills within a D&T curriculum, which is…

We quantitatively synthesized findings of quasi-experimental and randomized control studies of interventions designed to improve the mathematics achievement of secondary school students with mathematics difficulties (MD). We identified 45 studies (49 interventions) published between 1978 and 2020 and classified interventions into five categories:…

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…

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 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…
