‘What Works’ Rates Programs' Effectiveness
Department’s Web site for education research will cite smaller studies.
The Department of Education, in a bid to make its $15 million What Works Clearinghouse Web site more useful to policymakers and practitioners, quietly unveiled a new face for the site this month.
Begun in 2002, the What Works project is aimed at vetting research on educational interventions and programs so that decisionmakers can make informed choices about “what works”—or is likely to work—in their own schools.
The initial reports, posted on the Web site since 2004, mostly gauged whether individual studies met the clearinghouse’s tough evidence standards. So few studies passed muster, though, that clearinghouse operators worried that practitioners would get discouraged from using it.
To address the problem, the revamped Web site includes new “intervention reports” that contain program descriptions, information on costs to implement the program, and simple, Consumer Reports-style ratings on program effectiveness in specific areas.
To calculate the ratings, clearinghouse reviewers will also be allowed to weigh some smaller studies with strong positive effects as showing “potentially positive” evidence that a program works, rather then disregard the findings for failing to achieve statistical significance.
“This is an attempt to deal with what to do with this whole literature when there’s so little literature out there,” said Grover J. “Russ” Whitehurst, the director of the department’s Institute of Education Sciences, which oversees the clearinghouse.
Mr. Whitehurst discussed the changes during the May 8-9 meeting here of the National Board for Education Sciences, a 14-member group appointed by the president to advise the institute on setting priorities for its work. While board members applauded the changes, some independent observers offered a more skeptical assessment.
“The problem they’re facing is they don’t have anything to report, so they’re fishing for other results,” said Frederic A. “Fritz” Moser, a senior consultant to the Consortium for Policy Research in Education, a five-university research collaboration housed at the University of Pennsylvania in Philadelphia. “They’re caught in a dilemma they’ve created by stressing [methodological] rigor. Now they want to get back to relevance.”
However, Rebecca Herman, the What Works project director and a principal research scientist at the Washington-based American Institutes for Research, said the clearinghouse was not retreating from its commitment to setting high standards for educational research.
“We’re trying to help people focus on the body of evidence for an intervention and not just one study at a time,” she said.
The clearinghouse used the new format to review four character education programs: An Ethics Curriculum for Children, an elementary-level program developed by the Pittsburgh- based Heartwood Institute; Building Decision Skills, developed by the Institute for Global Ethics in Camden, Maine, and aimed at middle and high school students; Facing History and Ourselves of Brookline, Mass., which focuses on World War II and the Holocaust; and Lessons in Character, distributed by Young People’s Press Inc. of San Diego, for use in elementary and middle schools.
For the first time, the Department of Education’s What Works Clearinghouse has posted consumer-style ratings on the effectiveness of instructional programs. The ratings judge whether studies provide evidence that the program produces changes in three areas—students’ behavior, their knowledge or attitudes, and their academic achievement. The ratings were applied first to four character education programs.
The six ratings are:
● potentially positive
● no discernible effects
● potentially negative
|Behavior||Knowledge, Attitudes, and Values||Academic Achievement|
|Building Decision Skills||Not reported||Potentially positive effects||Not reported|
|An Ethics Curriculum for Children||No discernible effects||No discernible effects||Not reported|
|Facing History and Ourselves||No discernible effects||No discernible effects||Not reported|
|Lessons in Character||No discernible effects||No discernible effects||Potentially positive effects|
The resulting reviews, posted on the Web site two weeks ago, judge the four programs on how effectively they produce changes in three areas: students’ behavior; their knowledge, attitudes, and values; and their academic achievement.
No program was found to show “positive” effects, the group’s highest rating. But two programs—Building Decision Skills and Lessons in Character—got “potentially positive” ratings in some categories.
Mr. Whitehurst told the board on May 8 that the introduction of the “potentially positive” category also allows reviewers to weigh positive evidence from research that is well designed but “underpowered”—in other words, studies that may include too few students or classrooms to produce effects large enough to pass technical tests of statistical significance.
“Part of what’s going on here is that we are reanalyzing all the studies because many were misanalyzed, and the underpowered problem is greater when you do the analysis correctly than it appears in the literature itself,” Mr. Whitehurst said.
Now that the new ratings system is in place, project officials said, the clearinghouse will begin rolling out more reports. Currently, the Web site posts reviews in only two subjects areas: middle school mathematics and character education.
The clearinghouse redesign is part of a broader effort underway at the Institute of Education Sciences to make educational research more relevant to practitioners and policymakers.
Mr. Whitehurst also announced at the meeting that the institute had forged a formal agreement with the Council of the Great City Schools, a Washington-based group that represents the nation’s largest urban districts, to collaborate on research-oriented projects. Among the efforts on the two groups’ to-do list: forming an Urban Education Research Task Force, made up of researchers and practitioners, to advise the institute on the kinds of studies needed to improve learning in big-city schools.
“It’s easy to be relevant. It’s easy to be rigorous,” Mr. Whitehurst told the board. “It’s difficult to be both rigorous and relevant.”
