The author examined whether game play improves students' comprehension, attendance, and exam performance. The author designed three games; 120 students in introductory microeconomics classes participated in these experiments. The evidence showed that game play enhances students' attendance, comprehension, and exam performance. It also showed that…

Randomized experiments provide unbiased estimates of treatment effects, but are costly and time consuming. We demonstrate how a randomized experiment can be leveraged to measure selection bias by conducting a subsequent observational study that is identical in every way except that subjects choose their treatment--a quasi-doubly randomized…

The authors' data contain inter- and intra-class variations in experiments to which students in a principles of microeconomics course were exposed. These variations allowed the estimation of the effect on student achievement from the experimental treatment generally, as well as effects associated with participation in specific experiments. The…
