I was thinking that what the students did during the test here was what my classmates and I did for almost every homework assignment. We would work through the engineering problems (sometimes individually/sometimes as a group), go over them, ask/answer questions, and move on. I learned so much doing this (mostly that there is more than one way to perform analysis to arrive at an answer and that engineers love looking up the answer in the back of the book and working backwards).

I wonder if this would be more aligned with how the grading system works as a method by which periodic quizzes are given. We had lone wolves/busy students who couldn't participate, but I think everyone would have benefited from this as a class group activity.
