Published studies of intervention effects probably report effect sizes that are larger than the true effect size. There are probably many reasons for this, but one can be thought of as a "winner's curse." In this essay, I discuss evidence from two recent studies that highlight how evidence clearinghouses might inadvertently expose…

Biographies are one of our best tools for diversifying the curriculum. In this article, we describe The Biography Clearinghouse, a free resource designed to inspire teachers to use high-quality biographies in their classrooms. We then elaborate on curricular possibilities in K-8 classrooms. We end with a discussion of the Investigate, Explore, and…

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…

Clearinghouses set standards of scientific quality to vet existing research to determine how "evidence-based" an intervention is. This paper examines 12 educational clearinghouses to describe their effectiveness criteria, to estimate how consistently[underlined] they rate the same program, and to probe why their judgments differ. All the…

Identifying evidence-informed programming (e.g., strategies, activities, pedagogies) facilitates both the intentional offering of programming that should "work" and the use of the outcomes assessment process to evaluate program effectiveness. Evidence-informed programming is more efficient than unsupported programming because the…

Utah Leading through Effective, Actionable, and Dynamic (ULEAD) Education is required to report on successful K-12 practices in Utah and other states and propose policy changes to remove barriers to implementation successful practices. These practices should result from ULEAD's innovative research reports and repository development. There have…

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…

The What Works Clearinghouse (WWC) is an investment of the U.S. Department of Education's Institute of Education Sciences. Its purpose is to provide educators, policymakers, researchers, and the public with a central and trusted source of scientific evidence on what works in education. The WWC's goal is to produce high-quality products that help…

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…

We provide an overview of existing and emerging ways that institutional researchers can leverage National Student Clearinghouse data to expand a culture of data-driven decision-making across campus, with a focus on examples from the field.

The system of least prompts response prompting procedure has a rich history in special education research and practice. Recently, two independent systematic reviews were conducted to determine if the system of least prompts met criteria to be classified as an evidence-based practice. Both reviews used single-case design standards developed by What…

Using practical examples from a child welfare research capstone class, this article discusses how the California Evidence-Based Clearinghouse for Child Welfare (CEBC) can be used as a tool to teach social work students how to access, analyze, and interpret current research related to child welfare practice and help them apply their understanding…

Purpose: This article examines the state of progress of evidence-based educational policies in Europe and identifies organizations for the generation and dissemination of evidence. Further, it discusses some of the most relevant challenges facing the development of evidence-informed education policies in Europe. Design/Approach/Methods: This…
