Thanks for the tips.
I'm going to try and switch some things up next semester. I'll incorporate some of the things mentioned here, and also get on some of the lazier coteachers to really help me accomplish what I want to accomplish.
My stomach turns at the thought of giving students candy for answering a question, or for doing homework, or for not ripping out each other's hair . . . they should do these things, and they should be expected to do these things. It would never occur to a Korean teacher to give candy to a student for reading a passage out of a book, or whatever, and if a student were to say "기브 미 켄디이이이~~!!!" to a Korean teacher you can damn well be sure that the bamboo sword would come out.
. . . but, I need to come up with something for next semester. A way of making sure the basics are covered---everyone has books, worksheets, notebooks, pencils---and rewarding extra credit like participation. Maybe reward the day's top student or top 3. I like the idea Chris had of basicaly raffling off that bear for Christmas time last year, so maybe I could do something similar.

I'm curious, because I haven't seen any authentic demos and haven't talked extensively to many PS teachers, how your classes generally go. I see some of the lessons on here and in the JLP book, and I think "oh man, no way," but maybe I just expect too much?
Do your students come prepared? Are the generally chatty amongst themselves? Do they begin when you say "let's begin?" A lot of mine classes run smoothly, especially at my newer school, but then there are others that are really challenges. The advice I got from a Korean co-teacher was "teach English conversation" and when I pressed the issue, she said "Shane gave them candy," haha.
I'm becoming a little more convinced that it's difficult to run things the way a Korean would. I'm all for having a fun time and for doing comparatively easy lessons, but I expect the most basic of respect and preparedness. Greet me properly (no "hiiiiii," or "yo," or "hey you," or other catcalls), bring your materials, try hard, and don't tear up the room or each other.
