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…

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…

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…

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…

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…

The National Student Clearinghouse (NSC) has available for research a large data warehouse of enrollment and graduation information from 1993 to the present for nearly all postsecondary students in the United States. In this most recent academic year, 18 million currently enrolled students alone were added to the database. Some of the following…

Susan Imel is retired from Ohio State University. From December 1981 until December 2003, she was the Adult Education Specialist at the ERIC Clearinghouse on Adult, Career, and Vocational Education and Director from 1987 through 2003. This essay begins with a brief overview of the ERIC system including goals for the clearinghouses, followed by a…

In this article, we trace the development of the Campbell Collaboration and its renewed efforts to build a world library of accurate, synthesized evidence to inform policy and practice and improve human well-being worldwide. Campbell systematic reviews and related evidence synthesis products provide unbiased summaries of entire bodies of empirical…

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…
