The Effects of Connected Mathematics Project 2 on Student Performance (November 14,2008)

This independent efficacy research study, conducted by Dr. Rebecca Eddy of Claremont Graduate University’s Institute of Organizational and Program Evaluation Research, reported that CMP2 students demonstrated significantly greater gains in problem-solving, math communication, and math reasoning strategies than their peers using other math programs as evidenced by performance on the Balanced Assessment of Mathematics (BAM). In addition, CMP2 students demonstrated significant improvement from pretest to posttest in the areas of concepts and problems, estimation, and computations as evidenced by performance on the Iowa Test of Basic Skills (ITBS). The difference in achievement between Latino students and Caucasian students on the BAM assessment was significantly smaller than the difference between Caucasian and Latino students who used other math programs” The study will follow the 6th grade students into 7th grade.

Longitudinal Study of Connected Mathematics 2 (in progress as of 2006)

Preliminary work is underway on a comprehensive study of the implementation of Connected Mathematics 2. The national study, which will be coordinated by Horizon Research, Inc., will compare 25 pairs of schools. Each pair comprises a CMP2 school and an appropriately matched school that uses a more "typical" middle school mathematics curriculum.

According to the study's proposal, the three primary research questions are as follows:

  1. How does using CMP2 instead of a non-CMP2 middle school curriculum affect the tested mathematics achievement of students?

  2. How does using CMP2 instead of a non-CMP2 middle school curriculum affect "achievement gaps" among demographic groups of interest?

  3. How does variation of implementation fidelity of CMP2 affect student achievement?

Results of the study will be made available here upon its completion and publication.
