Improving Mathematical Problem Solving: A Research-Based Practice Guide

What Works Clearinghouse (WWC), a division of the Institute of Education Sciences (IES), publishes research-based education practice guides that address current educational challenges.  The most recent practice guide, Improving Mathematical Problem Solving in Grades 4 Through 8, provides five recommendations that educators and curriculum developers can use to help students in grades 4 through 8 develop better skills in mathematical problem solving. 

Unlike many of the mathematical educator guides floating around the Web, these IES publications are developed through rigorous research and the validity of this research is also evaluated.  After reviewing all available studies pertaining to the topic at hand, the authors of the practice guide assign a “level of evidence” (strong, moderate, or minimal) to each recommendation.  During this evaluation process authors examine individual studies and then consider the whole evidence base, evaluating factors such as the number, quality, and design of the relevant studies.  For more information on the role of evidence and the criteria for each level, see page 3 of the practice guide.  

Check out the practice guide and let us know what you think!  How helpful are the five recommendations?  Is the strength of evidence rating important to you? Does the evidence surprise you in any way?
