What Works Clearinghouse

WWC intervention reports summarize the research on a program or practice, and WWC practice guides provide research-based recommendations on a variety of instructional topics including teaching reading, writing, and math and managing behavior in the classroom. The guides offer strategies and tips that teachers can implement in their classrooms as well as solutions to common roadblocks they might encounter. WWC summaries and tips from the guides offer a quick reference for educators. Mathematica has played a central role in administering the WWC, including expanding the resources available to educators, revising and authoring standards for reviewing education research, and exploring an array of topics that are at the forefront of education decision making.
