Sorry about the lack of quality posts lately. Your old pal the Solipsist has been a bit overwhelmed the last few days. As any teacher can tell you, the beginning of the semester is a hectic time. Since I returned to Solipsist Central from the old homestead of New York, I've done a two-day training course for new tutors and attended a departmental "retreat." Tomorrow, the series of pre-semester activities continues with another meeting, and then classes begin on Friday.
I don't know why, either.
Actually, that's not true; I do know why, at least in theory. All college classes have a stipulated number of hours that students are required to complete: A three-unit class, for example, requires a total of 54 hours of classroom instruction. If that class meets Mondays and Wednesdays for 90 minutes each day, the class must have a total of 36 meetings. Classes begin on a Friday so that there are a sufficient number of Friday meetings for a class scheduled on Fridays. Why the class couldn't simply have an extra Friday at the end of the semester is a good question, and one that I think deserves a good answer.
Oh, I don't have a good answer, but rest assured that you deserve one.
