Abstract
We present an analysis on the differential effects of incentivizing homework in an introductory mathematics course at the United States Military Academy. We found that including homework as part of a student’s overall course average (incentive) led to a significantly higher performance (achievement) on homework assignments. However, doing homework only led to a significantly higher exam performance for medium-ability students. One possible explanation for our results is high-ability students may be able to grasp material with minimal out-of-class practice; medium-ability students benefit significantly from solving practice problems; and low-ability students may have difficulty in understanding even if they are actively practicing problems.
