Abstract
The effects of educational innovations are estimated by two different approaches. The first is the familiar regression framework. In the second approach, the grade of a given student is decomposed into the grade due to ability and the grade due to random guessing. For a given ability distribution, we show that an educational innovation would increase the mean and decrease the variance of the observed students' grades.
