Purpose: Multisite mediation studies are a cornerstone in mapping out developmental processes because they probe the mechanisms of a treatment while creating key opportunities to learn from and about variation in those mechanisms across sites. Despite the prevalence of multisite studies, a significant gap in the literature is how to plan such…

An extensive number of studies evaluating educational interventions are conducted and disseminated through peer-reviewed articles and conference presentations annually, but there is limited uptake of research among key stakeholders--educators and administrators (henceforth, practitioners; Farley-Ripple et al, 2018; Hollands et al., 2019; Slavin,…

Background: The emergence of causal research in education was almost strictly quantitative twenty years ago, however, that landscape has changed considerably. The number of intervention studies fielded and completed annually has increased substantially, and the quality of the evaluations is much more robust, including paying much greater attention…

Background: The Supporting Effective Educator Development (SEED) Grant Program aims to increase the number of highly effective educators by supporting the implementation of evidence-based practices that prepare, develop, or enhance the skills of educators. The three central goals of this program are: (1) Recruit, prepare, and retain effective and…

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. The WWC has historically prioritized internal validity over external validity in rating the quality of research. One critique…

Background/Context: Some observational studies involve multiple layers of treatment selection, specifically in the context of the extended time accommodation (ETA) for English language learners (ELLs). In ETA settings, the first selection occurs due to the eligibility rule, where students whose ELL English proficiency is below a certain threshold…

Literacy skills are instrumental to unlocking a child's full potential and have a well-established link to long-term life outcomes. Children who can't read at grade level by 3rd grade are four times more likely to drop out of school, have fewer career prospects, and earn lower incomes as adults. However, despite some progress on literacy rates,…

Youth in the U.S. face a mental health crisis--one that has steadily worsened over the past 10 years (Centers for Disease Control, 2023). Youth with disabilities may experience increased mental health risk compared to their peers without disabilities. Recent national surveys and systematic reviews reveal that mental health risk may be elevated for…

Background: Research highlights the value of coaching to support elementary school teachers' use of effective classroom practices (Cappella et al., 2012; Owens et al., 2017). Coaching is particularly useful when teachers implement new or complex strategies, which can include culturally-responsive and equity-centered practices (i.e. strategies that…

Background/Context: Chronic absenteeism is a serious problem that has been linked to lower academic achievement, diminished socioemotional skills, and an increased likelihood of high school dropout (Allensworth et al., 2021; Gottfried, 2014). As a result, many schools have begun to embrace early warning systems (EWS) as a tool to identify and flag…

Background: Observation Studies, Unmeasured Confounding, and Sensitivity Analysis: An important part of educational research is identifying important, potentially causal, factors that influence children's learning from observational studies. However, it is well-known that discovering such factors from observational studies can be biased due to…
