I have had a problem with exam days and introducing new material on the same day. The way the class is designed is 4 hours. Often I will need to test on the same day as a lecture (being an accelerated program we don't have many class meetings). If I lecture before the exam, nobody pays attention to the material because they're too busy worrying about forgetting exam info. So, I tend to exam first, and then hold the lecture last. It just seems, then, that they are all paranoid about the exam they just took and can't focus on anything else. What does everyone else do in this situation?
