In the week or two before Spring Break, it’s customary for lab chit-chat to turn towards what we look forward to on break. This spring, as my colleagues told me how they anticipated getting out of town or getting some writing done, I told them that I was looking forward to my students’ midterm. “I’ve never given a midterm,” was the repeated response. Before this semester, neither had I. So I’ve decided to write here about why I gave the midterm and how I used the Lab resources to enhance it.
