Algebra teachers should show students both correctly and incorrectly solved problems and have students discuss them, according to a new algebra practice guide published by the U.S. Department of Education’s Institute of Education Sciences.
The guide, prepared by Mathematica Policy Research and released last week through the What Works Clearinghouse, includes three specific evidence-based strategies for teaching algebra. It’s based on a review of studies about algebra instruction that were published between 1993 and 2013.
