Gardiner campbell suggests that we might ask the following questions, did you read the material for to day's class meeting carefully? Or yes, two or more times. Ideally, students would transmit their scores electronically, and the teacher would be able to do a quick class average at the beginning of the meeting. The teachers should also assign themselves a score, with a colleague substituting for classmate, for example, or perhaps with a different set of questions. Altogether, it would be interesting to chart the classes scores over a semester and compare one section's scores with another.
