The Institute of Education Sciences (IES), the research arm of the U.S. Department of Education, released its updated website today, and it is pretty spectacular: http://ies.ed.gov/ncee/wwc
IES sponsors and conducts research that provides evidence for education policies and practices. Their new website makes it easier for policy makers to find evidence-based policies, which is especially helpful given the new flexibility that states and districts have under ESSA (Every Student Succeeds Act).
You can now look up research for programs that have been tested for improving educational outcomes in various subjects (Math, Literacy, & Science), for student populations (English Learners, Students with Disabilities), and various age groups. You can also cross-filter to find programs related to multiple groups (Math achievement for Students with Disabilities in High School, for example). The evidence also shows how many studies were conducted, how many students were involved in the study, and the size of the effect.
My only critique would be the lack of evidence for some types of programs, but that’s a content-based issue, not related to the website’s format. So, if you want a program that improves Teacher Excellence, you’ll only find one that has shown positive effects, which may or may not be applicable to your district. But, the upside to this is that researchers and policy makers can more readily see where the gaps in evidence lie and start working to fill them in.
