Note that only comparison of posttest results for the BAM can be used for purposes of the outcomes analysis. The BAM is not vertically scaled, and results are not comparable on the same scale across different grade levels. Consequently, only a comparison among Spring 2009 results is presented.

Subgroup Results: enVisionMATH vs. Other Math Programs

Evaluators also analyzed subgroup differences between enVisionMATH and other math programs. Results showed a significant difference between enVisionMATH students and students using other math programs in the following subgroups: 3rd graders and females. Specifically, enVisionMATH students who were females showed greater gains on the MAT8 Math Computation and GMADE tests as compared to students using other math programs, t-ratio=14.06, p=0.03 and t-ratio=6.79, p=0.04. Program effects were also found for third- grade students on the MAT8 Math Computation in that the enVisionMATH program had a more positive impact on 3rd graders as compared to other math programs, t-ratio=12.78, p=0.03.

“The program is very engaging and the kids love it.”

Results by Type of Control Program

In addition, the positive effects obtained on the enVisionMATH program were observed across a number of different schools who used a variety of types of control programs. Specifically, enVisionMATH students performed significantly better than students using other math programs that were purely investigative and inquiry-based, as well as students who used more traditional basal math programs during the first year of the study. During the second year of the study, 5 of the 6 schools used basal math programs. The students using
