Hi everyone, I'm new here. I began my first week as a teacher on monday. I'm technically a long term sub for now and I've been told I'll be able to keep the position at the end of the school year if I do a good enough job. I teach elementary school band and middle school piano. I start my day in the morning teaching band at the elementary school. For the most part, it's great and I love every second of it. But then, I head over to the middle school and teach piano and things are a little different. Now, one of my classes is fine. They are a 7th grade class and can get out of hand at times, but for the most part respect my authority and want to be in the class. However, later on I have an 8th grade class and it is the exact opposite. The class is a complete circus. I can't get students to sit down, do what they're asked, stop talking back and stop interrupting me while I'm trying to lecture. Today, my class was absolutely uncontrollable. I tried to start the lesson with a smile and enthusiasm. It turned into me firmly asking the students to stop playing on the pianos or talking while I'm talking. My frustration grew as another student began questioning my understanding of the subject. "That's not what our last teacher taught us. Are you sure you know what you're doing?". I, however, calmly tell them that I am a certified teacher and I've been involved with music my whole life. The students then began unplugging the pianos and pretending like they were broken so they don't have to play. Finally, after students had turned the volume on the pianos all the way up and started using them to make lots of annoying sound effects, I finally snapped and raised my voice, telling them that they can either respect my classroom rules or go to the office, which one student immediately decided to challenge by once again, making sound effects. Thinking I could make an example out of him, I sent him to the office immediately. I thought that would stop the behavior, but students continued to do the same thing throughout the class period. Finally as the bell rang and the students were leaving my class, one of them threw a carton of milk at my desk and it exploded everywhere. It happened so fast that I didn't catch which student did it. The class is completely out of control and I'm overwhelmed as to what I should do. The worst part? Apparently this class was a very well behaved class before the previous teacher left. So they are now just being like this because I'm here. I'm afraid to ask my peers for help especially after listening to conversations that some of them have during lunch about other teachers. I'm pretty sure the first thing they'll think is "Why are you a teacher if you can't control a classroom?" I feel so disrespected that it doesn't seem like there's any coming back from it. I don't really understand what I'm doing wrong. I've familiarized myself up and down with standard classroom management procedures. I've asked friends of mine that teach at other schools, and they give me a list of things that I should be doing which would be great, except they haven't given me a suggestion that I'm not already trying. Any advice would be GREATLY appreciated. Thank you!
