Kindy teaching is the easiest for me, but requires a lot of follow through. If you say you are going to do something whether reward or punishment, you had better damn well do it. You also need a schedule and be able to communicate it to the young ones. You’ll see surprisingly little as far as TPR which should be a cornerstone for any class, though it can make you very lazy.
The nazi part has me a bit baffled. I’m strict and if they are screwing off in a class disrupting manner, there getting called on it. For the students who started too late or just aren’t interested in learning English, I cut them some slack. These are usually my worst students.
The important part is to keep it fun and change activities regularly and break them into groups. Though it may go against your boss’s beliefs. You can teach more to a group of 16 in 4 groups/10 minutes a group versus teaching the whole class for 40 minutes and have a better idea where each student is.
You can’t be high, a clown all the time, and/or be a total whiner. I imagne you could do it high, but when you come down around a bunch of excited kids, then it is going to suck. I don’t believe many bosses in Taiwan give “toke breaks.” Being a clown is nice, but once you start, you can never stop, sort of like being on a runaway horse. As they will expect, what you have led them to expect. You can not be a whiner. There is no point in taking the job if you are. If you think they are too young to be in school, too stupid, and/or the material is worthless, then do yourself and your boss a favor and quit.
I don’t know about self sonfidence, I think I’m confident. Most teachers that did well seemed confident and somewhat carefree. The ability to let go of that which does not matter.
