In the video segment by Professor Thomas DeLong, I found it helpful to take note of what worked and what did not work in the classroom as far as the instructor could determine. The suggestion of taking 20 minutes after each class to write down in two columns "What I Thought Would Happen" and "What Actually Happened" was an excellent way to analyze your presentation of an assignment or the entire course. As you assess your students, this is a good way to assess yourself.
