I take 17 classes for 45mins each in the library every week. One boy in his final year before high school refuses to participate in the lesson, and has left the library twice without me knowing he has gone. When the other students are working on the computers he asks if he can play games on the computer, and when I refuse, he is rude and belligerent. He constantly says he hates school and everything about it. He will say other children are teasing him and he walks off, when I know the rest of the class are on task and paying him no attention. He brings toys into the library when he can, and it makes it difficult for me as when I ask him to put them away he refuses. As I only see the class once a week I cannot watch him constantly, there are 26 lovely children in the class who deserve my attention. If I ignore the behaviour we walks out of the room or rips up his work saying he hates everything about school. Any advice on how to deal with this student is appreciated. There are no helpers with me and no funding for this student so that is not an option.
