Like Roy, I also have a crappy teacher situation. Today, for the first time after a year of teaching with him, I decided upon a name: Douchebag-Sensei.
Yes, it's similar to Roy's Dipshit-Sensei but hey, inspired by his brilliant use of dipshit, I came up with "Dipshit-Sensei" anyway. They mean virtually the same thing in my book, but you know ... we can't be eating the same dish (so to speak).
Douchebag-Sensei has actually managed to garner a reputation amongst Saitama highschool teachers as being the least likely teacher to give a shit about teaching. Even before he taught at the current low-level technical school, he taught just as badly at a decent school .
What gets to me is that his shitty attitude affects the students (naturally). Sure, most of them don't give a damn about English anyway, and I don't expect them to. But the teacher's role as I see it is to nurture what interest there might be. If a student asks a question during an activity or shows any interest at all, I'll do my best to work with it. DB-Sensei (acronym usage definitely ripped from Roy) quashes it. Today a student was talking to both of us about the current activity. He was obviously interested in learning more about the usage of the target sentence and its alternatives. Instead of trying to work with this interest, DB pretty much said "yep that's how it works," turned away, and went back to sleeping standing up. I tried to work with the student more, but my bad Japanese rapidly became a barrier to further learning.
If only I could design my own activities for the students instead of using the world's worst English textbook. Every time I suggest an activity, without fail he'll very evasively (which is what passes for politely here) nix anything interesting. And we go back to reading from the world's worst English textbook.
To top it off, Douchebag isn't going anywhere soon, as I have the feeling that his poor performance at previous schools is the very reason he's been placed at a low-level school.
If anything, it's one more reason to study Japanese more.
