I teach a large all girls Year 10 class. Most are low ability and several have emotional or home difficulties and a few have sen. They spend lessons with their phone out. School policy is to confiscate them if seen in lessons but it has now got to the point where they are refusing to give me their phone. Any task on the computer and they are constantly on the internet or watching music videos. If they are sat at their desks I am constantly battling with them to put away makeup, hairbrushes and food. When I demand their attention I spend every few minutes waiting for silence as the don't stop chatting amongst themselves. They are constantly swearing and they try and argue with everything I say. They are equally rude to the TA who tries his best too. I have kept kids behind, parked the worse offenders with the hod and where I have managed to-confiscated mobile phones. I praise them when they are doing well or participating too. I have phoned parents but to be honest the majority are really not interested and don't seem to want to even speak to their children. I don't know what else I can do? I teach this class 6 hours a week and it is a great source of stress for me, I am at the point where I am doubting my ability as a teacher (I am a NQT) and am wondering if I am right for the job.
