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…

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 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…

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…

The "Knowledge Is Power Program" ("KIPP") is a nonprofit network of more than 200 public charter schools educating early childhood, elementary, middle, and high school students. The What Works Clearinghouse (WWC) identified four studies of "KIPP" that fall within the scope of the Charter Schools topic area and meet…

This article details the Northwest Indiana Public Safety Data Consortium (NWIPSDC), a privately funded data-sharing network housed at Indiana University Northwest, an anchor institution, that includes several private-sector participants and over 30 public safety agencies at all levels of government (local, county, state, and federal).

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…

"Better Evidence, Better Choices, Better Schools," a recent report from the Center for American Progress and the Knowledge Alliance, focuses on the evidence-based research provisions in the Every Student Succeeds Act (ESSA). ESSA provisions ask districts and schools to consider various sources of evidence, make judgments about the…
