Clearinghouses are influential repositories of information on the effectiveness of social interventions. To identify which interventions are "evidence-based," clearinghouses review intervention evaluations using published standards of evidence that focus primarily on internal validity and causal inferences. Open science practices can…

In 2020, the What Works Clearinghouse (WWC) for single-case experimental design (SCED) studies released an updated version of their standards and procedures handbook (Version 4.1). Because of these updates, there is a need to understand the implications for the field in terms of quality rating of the design, and subsequent synthesis of evidence at…

The What Works Clearinghouse (WWC) is a source that is used to report the empirical evidence for interventions. The purpose of this review was to understand the presence of Black children in research that has been classified as Meeting the Standards With and Without Reservations by the WWC. Results indicated that 16 interventions met the WWC…

Despite a history that can be tracked to 1867, the US Department of Education is a relative newcomer to applying evidence standards to education research. The What Works Clearinghouse (WWC) reviews intervention research to support evidence-based decision making. This is done by applying standards of research quality to studies and giving those…

The What Works Clearinghouse (WWC) seeks to provide practitioners information about "what works in education." One challenge in understanding "what works" is that effect sizes may not be comparable across studies, which limits the ability to compare the relative effectiveness of multiple interventions. One factor that…

As the body of scientific evidence about effective policies and practices grows, so does the need to effectively communicate that evidence to policy-makers and practitioners. Clearinghouses have emerged to facilitate the evidence-based decision-making process for education practitioners. While the results and methods for developing and analyzing…

Following the theme of the first two presentations, this presentation will focus on the choices available for research synthesis when summarizing research evidence. The presenters will describe the current research synthesis practice of the What Works Clearinghouse (WWC) as well as several alternative models, including inverse-variance weighted…

The purpose of this investigation is to report about study identification practices across evidence-based registries and clearinghouses in social policy fields, which serve as a resource for scientific, evidence-based decision-making about practices about desired outcomes in these social policy fields. The information retrieval procedures of the…

We examined the extent to which mathematics program evaluations that have been conducted according to methodologically rigorous standards have attended to the theories underlying the programs being evaluated. Our analysis focused on the 37 reports of K-12 mathematics program evaluations in the last two decades that have met standards for inclusion…

The What Works Clearinghouse (WWC) is a central and trusted source of information of scientific evidence for what works in education. Towards that end, the WWC summarizes research on a range of practices, programs, and policies (interventions) and disseminates that research in a variety of forms on the free public website. In recent years, the WWC…

The push for evidence-based practice in education has led to a range of initiatives aimed at bridging the gap between research, policy and practice. Among these are the establishment of brokerage agencies with a mission to synthesise the findings of educational research. This development has been the subject of extensive controversy over the last…

Beginning at a local two-year college and then transferring to a four-year institution has been one of the most affordable ways for students to earn a bachelor's degree. Yet transfer pathways from two- to four-year institutions are often complex and confusing, and too many students who begin at a community college and aspire to earn a bachelor's…

One purpose of education research is to develop and rigorously evaluate the effectiveness of programs for supporting students' learning and achievement. The Institute of Education Sciences has amplified that purpose (Shadish & Cook, 2009) and attempted to improve the methodological standards for conducting such work--primarily through the What…

There are few tools that exist to measure knowledge mobilization (KMb), the process of connecting research to policy and practice across diverse organizations and sectors. This article reports on a comparison of KMb efforts of 105 educational organizations: faculties of education (N = 21), research brokering organizations (N = 44), school…
