My school do not allow Year 11 to go on study leave. I have been allocated a Year 11 group for 5 hours a week to supervise them revising for Maths, English and Humanities exams. The group are somewhat challenging, they are students who have been removed from other lessons for various social/emotional reasons and therefore are focusing on the core subjects for GCSE and so I support them when they normally would have been in their options subject. The problem I am having is they are point blank refusing to revise. They are logging on to the computer and surfing the net the whole time or if I ask them to come off the computer, they sit staring into space, chat or just put their head on the desk. I am at my wits end, I don't know what to do. They know they are leaving so don't seem to care about listening to me or the school rules. Two of the students didn't show up for my lesson today and it turned out they were truanting. Is there anything I can do? I feel useless at the moment.
