Back in the stone ages, when I was a student, it was pretty common to have class MWF from 3-4. And not unheard of to have a lab on Friday from 2-5, even.
It was common enough that the Geology department had a legendary course, Geology 500, which met every Friday at 5pm for departmental beer and chat.
In more recent times, Thursday has become the new Friday, and around here, at least, it's rare for us to have a class on Fridays that goes later than 2pm. I taught a MWF 1-2pm course last semester, and the classroom wing was nearly empty except for me and my students.
I feel the urges, too. Most of us in my department can manage a "non-teaching" day during the week, working around our usual 11 credit hour load. For folks on a MWF basic schedule, that usually means you choose either Tuesday or Thursday for the "non-teaching" day.
Folks who teach most of their classes on Tuesdays and Thursdays usually choose either Monday or Friday for their "non-teaching" day; there are times when you can manage both, or sometimes one and Wednesday. It's easy to see the appeal, isn't it?
Students, too, like the same scheduling, often. That's especially true for students who try to fit a whole week of work into four days, Friday, Saturday, Sunday, and Monday, to support themselves while they work at classes on Tuesdays, Wednesdays, and Fridays. Or some of them like to "go home" a lot, and plan their schedules around those visits. Or whatever.
I think there's been a mutual movement, with faculty and students both wanting more Tuesday/Thursday courses, and fewer courses late on Fridays.
Yesterday, I was advising a student and talking with him about what courses to take in the coming semester. He's in a fairly rigid program, and has to take certain set general ed type courses. So, he'd filled in his schedule, but was on the low side of credits for the semester, especially if he wants to graduate in a timely manner.
Here's what his schedule looked like:
Monday afternoon, late, three hours, upper level option for major.
Tuesday / Thursday, starting at 9:30, running three straight courses.
Every single course he needed, except for the Monday afternoon course, was only offered during those three prime slots on Tuesdays and Thursdays, starting at 9:30. We looked at options for general ed courses, all T/T in the three prime slots. We looked at program courses, all T/T in those prime slots.
So I looked. And out of 40 some courses in my department from sophomore level up, only 10 are on Mondays, Wednesdays, and or Fridays. (Some are a late evening one day a week, and I counted those).
I think we (including me) have done ourselves a world of hurt this semester by scheduling so many of our courses against each other. In budget-driven times, I wonder if some of our courses are going to be cancelled, and those of us with contracts will suddenly be teaching more comp or something.
Here are my fingers crossed for decent enrollment in my Chaucer course!
