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…

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…

With journal price increases continuing to outpace inflation and library collection funds remaining stagnant or shrinking, libraries are seeking innovative ways to control spending while continuing to provide patrons with high-quality content. The Spencer S. Eccles Health Sciences Library reports on the evaluation, implementation, and use of…

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…

Drawing on our five years of experience developing WWC evidence standards and reviewing studies against those standards as well as current literature on the design of impact studies, we highlight in this paper some of the most critical issues and common pitfalls in designing and conducting impact studies in education, and provide practical…

KIPP (Knowledge is Power Program) is a national network of public charter schools whose stated mission is to help underserved students enroll in and graduate from college. Prior studies (see Tuttle et al. 2013) have consistently found that attending a KIPP middle school positively affects student achievement, but few have addressed longer-term…

A large body of literature documents the central importance of fidelity of program implementation in creating an internally valid research design and considering such fidelity in judgments of research quality. The What Works Clearinghouse (WWC) provides web-based summary ratings of educational innovations and is the only rating group that is…

This technical brief describes updates to a database of dropout prevention programs and policies in 2006/07 created by the Regional Education Laboratory (REL) Northeast and Islands and described in the Issues & Answers report, "Piloting a searchable database of dropout prevention programs in nine low-income urban school districts in the…

On November 5, 2002, Congress passed the Education Sciences Reform Act of 2002 (ESRA), establishing the Institute of Education Sciences (IES, or the Institute) and its board of directors, the National Board for Education Sciences (NBES, or the Board). The Institute reports to Congress yearly on the condition of education in the United States. The…

Despite evidence that some dropout prevention programs have positive effects, whether districts in the region are using such evidence-based programs has not been documented. To generate and share knowledge on dropout programs and policies, this report details a project to create a searchable database with information on target audiences,…

The What Works Clearinghouse (WWC) provides online reports to the public about the scientific evidence for educational interventions. The quality of these reports is important because they effectively tell the non-scientific community which programmes do and do not work. The aim of this brief review is to assess WWC's report on a clinically…

This report identifies the different settings in which summer programs for disadvantaged youth most commonly take place--schools, parks and recreation departments, community--and faith-based organizations, and child-care programs-- and examines the limitations and opportunities presented by each in building better programming. It reviews broadly…

Recent trends have resulted in schools implementing an extensive range of preventive and corrective activity oriented to students' needs and problems. Some programs are provided through a school district, others are carried out at, or linked to, targeted schools. Some are owned and operated by schools; some are owned by community agencies. Few…

"Keeping Pace" has several goals. First, it strives to add to the body of knowledge about online education policy and make recommendations for advances. Second, it serves as a reference source for information about programs and policies across the country, for both policymakers and practitioners who are new to online education as well as those who…
