Sometimes students make us crazy. It's true.
But often enough, instructors and professors drive students nuts as well. Here are some few of the ways. Feel free to add your own!
1. Have a sexual or dating relationship with a student. This may seem okay to the one student, if s/he doesn't feel that s/he's forced, but it's still creepy. To other students, it's obvious that the one student is going to be favored in ways that will disadvantage them. Extra points for flaunting your relationship in front of the whole campus.
2. Grade erratically. Don't tell students what you expect on an assignment or how to do better. If you can use the stair method in front of your students, all the better. Don't tell students what a grade of 16 means, what scale it's on, or how much the assignment counts for in the course.
3. Consistent lateness. The prof who always comes in ten minutes late is bad enough; when that same prof holds the class ten minutes late to "make up" for his/her lateness, that's close to criminal. Or at least really, really rude. And, of course, be absolutely firm that you don't accept student work even a minute late for any reason whatsoever.
4. Miss office hours or blow students off. This is most effective when you've been busy with your favorite student for an hour, while other students are lined up sitting on the floor hoping for some help. And then you just don't have time to talk to those students. Double points if you can decline to talk to the students with a sexist or racist comment thrown in.
5. Don't hand out a syllabus or assignments. Just give information verbally at some point. Or not. And change your mind about things several times for maximum unclarity.
6. Wait forever to grade papers. Procrastinate until the end of the semester, and then just assign grades randomly. If you can blog about procrastinating, all the better.
7. Don't respond to emails or phone calls, even if you're sitting in the office while they're on the phone. Double credit if you're avoiding an advisee who needs a form signed before the deadline and s/he's been trying to reach you for three weeks or more.
8. Complain endlessly about how hard you work and how underpaid you are. Complain especially loudly while standing in the store where your student works as a checkout or stock clerk for minimum wage. Extra credit if you hire a student worker to clean your house or babysit your kids but don't pay even minimum wage because you're so devastatingly underpaid.
9. Teach from your own text, which you "update" every year by changing the pagination and one or two illustrations. Otherwise, make no changes in your lectures, because really, it's not like the laws of physics have changed in the past billion years or two.
10. Make rude comments. Comment on your students' tattoos, especially if you can talk about their "tramp stamps." Note that some students are just stupid or whatever. Tell female students that they shouldn't worry about grad school or grades or whatever because they're just going to get married anyway and it's a waste of resources to teach them anything.
