I like the idea of Monday-Wednesday-Friday courses. Three 50-minute class sessions each week can help prevent students from getting bored in class. These short sessions are also more easily filled with a class exercise or discussion, allowing me to cover fewer topics in more depth.
Until the beginning of this semester, I had never taught a Monday-Wednesday-Friday course. In graduate school my courses were either once or twice a week. I never really considered the ramifications of this until the semester got underway and I realized that there are not enough week days to prepare for two new MWF preps.
So far this semester I’ve been preparing for each class session a day or two in advance. This means that I prepare for Wednesday on Monday or Tuesday and Friday on Wednesday or Thursday. This also means that the only in-office time I have to prepare for Monday’s class is Friday afternoon. Unfortunately, I can rarely prepare quickly enough to avoid my prep time overflowing into the weekend.
Someday when I only have to prep one class (or fewer!) a semester, this may not be too bad. As it is I’ve resolved the problem in the near term by arranging my spring preps for Tuesday-Thursday.
