I expect the instructor to be organized and knowledgeable about their subject, have nice samples, be fun and friendly, and come around to each person if only to say how nice their project is coming along. I had a class once where the teacher sat up at the front and talked only. No coming around to encourage us or anything. And another time the teacher was not very friendly, almost sarcastic. I like to feel the instructor is enthusiastic about what they're teaching and make me feel that I'm not dumb because I don't get it. Of course I also want to feel that I learn something new too!
