I'm not a teacher. I've never been stuck in a classroom with 30 kids trying to convince them to want to learn. However, I've been a student, and never have I ever felt more disrespected than when a teacher said or did any of these 10 things. I realize it may be "part of a teaching method," or "just trying to control the classroom," but that isn't a good enough excuse. Teachers can't force students to read, they can't force them to want to come to school, but they can respect students enough to warrant respect in return (even though they can't force students to respect them either). So if teachers avoided these 10 things, I hypothesize that their students would respect them more (and like them more...).
