Bridges in Mathematics. WWC Intervention Report
What Works Clearinghouse
"Bridges in Mathematics," published by the Math Learning Center (MLC), is an elementary school math curriculum covering kindergarten through fifth grade that focuses on problem solving and skill building, and applies a combination of whole-group, small-group, and independent activities. Lessons incorporate visual models, including manipulatives, to reinforce learning. The What Works Clearinghouse (WWC) identified 23 studies of "Bridges in Mathematics" that were published or released between 1985 and 2008: four studies are out of the scope of the review protocol because they have an ineligible study design that does not meet WWC evidence standards; one study is out of the scope of the Elementary School Math review protocol because it is not a study of effectiveness; and eighteen studies are within the scope of the review protocol and have an eligible design, but do not meet WWC evidence standards. The lack of studies meeting WWC evidence standards means that, at this time, the WWC is unable to draw any conclusions based on research about the effectiveness or ineffectiveness of "Bridges in Mathematics."
