\subsection{Evaluation of gains in competency}
We measure student gains \citep[see, e.g.,][]{hake1998interactive} by incorporating a pre-test and post-test into the course. We will ask questions from the pre-test again, either on in-class quizzes or on the final exam. This allows us to compute a
mean gain in student competency,
\begin{equation}
\label{eqn:gain}
\langle g\rangle = \sum_{i=1}^{N} \left( \frac{S_{\mathrm{post}} - S_{\mathrm{pre}}}{S_{\mathrm{max}}-S_{\mathrm{pre}}}\right)_i,
