3. Teach kids to stand up when a teacher enters and leaves a room, and teach them, no, put them to clean their own class rooms as part of their daily school day.
Sorry, but if you honestly believe this one, you are quite out of touch with how "bad seeds" behave. Having kids stand up just gives a very easy way for them to disrespect their teachers. Those who don't want to stand up won't. As a result, they will either 1) be reprimanded, which many will just rebel against even more or 2) you do nothing about it, and further distinguish and separate the "good" from the "bad". This is not how you encourage respect between student and teacher. All teachers I liked and got along well with, from early elementary to late college, were ones who treated me as just another person. They didn't force me to do stuff for the sake of "that is what you are supposed to do", and they didn't make me treat them like my superior. Because I liked those teachers and respected them for the way they treated me, I actually felt bad not doing my class work in those classes.
