The second research hypothesis was that students who study economics and mathematics
together in middle school mathematics classrooms will perform better in mathematics
than students who study mathematics alone. The data were divided into two groups,
sixth-grade students and seventh and eighth-grade students. The difference between the
experimental and control group scores, although not always significant, was always
positive suggesting that learning economics in the mathematics classroom complements
learning mathematics and does not detract from learning mathematics.
While the differences in mathematics learning were not significant, the positive results
suggest that further study and analysis of an integrated approach to teaching mathematics
and economics on student learning are warrante
