I occasionally check a discussion board from an on-line community I used to be part of, mostly to see the old names and what folks are up to. Most of these folks are younger than I, and right now there's quite a rant up from one member about a horrid college prof s/he has. Of course, a couple people then responded by adding their own horror stories.
Some of these stories sound really bad; others sound like a prof said something a bit uninformed, and the student knows better, and now thinks the prof is an idiot. I know I've done that. (What the heck was the 30 years war really about? How did it start?) (And, to be honest, don't a fair number of 18 year olds think older women are idiots anyway, just for existing and not doing their laundry?)
But when I think back, I can think of maybe two or three profs I had who were sort of bad, but no horror stories. I had a prof for Fortran who basically read off overheads for every lecture; our text was a photocopy set of all the overhead slides. Not great, but I did manage to learn some Fortran. Then I had a genetics class for which the profs (one of whom is very famous) basically lectured from their textbook, complete with slides taken from their textbook, in a large, darkened lecture hall at 1pm. It wasn't that they were awful or uninteresting, but everything combined to make it hard to stay awake. (You know these folks are all doing the same thing in powerpoint now, right?)
I had a couple others who were boring, or worse, got off topic and went on for a bit about other stuff. (I avoided enrolling in a class where the prof was reputed to spend 45 minutes trying to take roll.)
But true horror stories? Nothing I can think of that would qualify. But maybe time has whitewashed my memory?
I feel sorry for the folks on that board if their profs really are that bad. And I know one poor prof can stand out even though most are pretty good.
