I found myself in a unique position today. A sophomore was chatting during a reading period. I asked him once to stop and he didn't take responsibility for his actions: "What did I do? I didn't do anything." After continuing, I told him to sit at a table in the back of the class. Basically, he didn't respond and didn't do as I said. After ordering him twice, I gave up and went back to my desk. He came up to my desk and asked to go to the principal's office. I said "Sure, and take your stuff with you." He got to the door, turned around and started asking me "Why?" I said "You know why." He just kept asking. I went to phone the principal, but he didn't pick up. I kept getting asked "Why" and so I just sat at my desk and stared until he gave up and left. When he left, he said "I hate this f***** class." 2 other schysters in the class also decided to leave and slammed the door as they exited. I asked the remaining students if anyone else wanted to leave, they laughed and continued reading. So I closed the door. Normally that kid is great to have in class. He participates frequently, though sometimes tries to get me off-task. Sometimes his interactions are inappropriate or disrespectful; half the time he polices the behaviors of others. So when I call him out or attempt to discipline him, he cops this attitude on me. He thinks he didn't do anything wrong, or at least says so. To top it off, after school, I found out that somebody had spit on my car. Coincidence? I've asked veteran teachers and had a meeting with my mentor and principal. Some advice I got was to leave my door open, call the principal to come escort the student out, use sarcasm, chew him out, be very specific with expectations, use less aggressive tone, etc. I am not really sure how to approach the situation. I didn't want to escalate the situation, but at the same time, I really felt like chewing him out. Any advice on this?
