WWC Review of the Report "The Effects of POWERSOURCE[C] Intervention on Student Understanding of Basic Mathematical Principles". What Works Clearinghouse Single Study Review
What Works Clearinghouse
The study examined the impact of "POWERSOURCE"[C], an intervention consisting of formative assessments, instructional resources, and professional development designed to help teachers provide individual instruction to their students in Algebra I. This study took place in seven districts in Arizona and California during the 2007-08 school year. Researchers assessed the effectiveness of "POWERSOURCE"[C] by comparing student performance on a mathematics achievement test. Results were presented for a composite score and for the three subscales that comprise the main achievement outcome. The outcomes assessed dimensions of student performance in algebra and were constructed from a range of national, state, and local assessments. The study reported that students of teachers who were assigned to use the "POWERSOURCE"[C] intervention performed better on questions about properties of arithmetic. The What Works Clearinghouse (WWC) did not confirm this finding to be statistically significant after adjusting for the clustering of students within teachers as the unit of assignment. The research described in this report for the sample that randomly assigned teachers to condition meets WWC evidence standards without reservations. Appended are: (1) Study details; (2) Outcome measures for the mathematics achievement domain; (3) Study findings for the mathematics achievement domain; and (4) Supplemental findings by domain. A glossary of terms is included. (Contains 1 endnote.)
