In 2000, the ARC Center at COMAP in Lexington, Massachusetts, received funding
from the National Science Foundation (NSF) to carry out a large-scale study
of the effects of reform-based mathematics programs on student performance
on state-mandated standardized tests in Massachusetts, Illinois, and Washington
State. The study examined the performance of students using the three elementary
programs developed with NSF funding and supported by the ARC Center, including
Everyday Mathematics.
The results described in this poster focus exclusively on the Everyday Mathematics
schools and students included in the study. The findings here are based on
the records of over 78,000 students: 39,701 students who had studied with
the Everyday Mathematics curricula for at least two years and 38,481 students
from non-using comparison schools carefully matched by reading level, socioeconomic
status, and other variables.
The results show that the average scores of students in the Everyday Mathematics
schools are significantly higher than the average scores of students in their
matched comparison schools. The results hold across the different state-mandated
tests, and across topics ranging from computation, measurement, and geometry
to algebra, problem solving, and making connections. The study compared the
scores on all the topics tested at all the grade levels tested (Grades 3-5)
in each of the three states. Of 34 comparisons across five state-grade combinations,
29 favor the Everyday Mathematics students, five show no statistically significant
difference, and none favor the comparison students. The results also hold
across all income and racial subgroups -- except for Hispanic students, where
Everyday Mathematics students have higher (but not statistically significantly
higher) average scores.
