I teach an aspergers student AS Business Studies in a sixth form college and he is very rude and offensive to me and questioning my teaching ability and subject knowledge.He is only taking as he needed to do 4 alevels so 'take business'. Todays comments included I am bad teacher, i dont know my subject, he could do a better job than me teaching, he doesnt see why he should attend lessons as he could learn the whole syllabus in 2 weeks and do well in the exams and that he and no one else learns anything in my lessons. He refused to do his homework last night as he was too busy helping in running a business which is something i know nothing about. I had an incident with him on the last day of the autumn term where he refused to do the work set as it was boring and pointless and he had done it already and wasnt going to do it and then starting implying im a bad teacher, i treat him differently in a bad way and that had something on me that he was going to use against me. He also complained at October half term that my lessons are too loud and that they should be taught in silence - the class should be silent at all times. He isnt doing as well as he could be in my subject because he doesnt listen to feedback as to how to improve his written work. His support worker claims there are no issues in his other subjects - physics, maths and electronics but i know there is such as not following instructions in maths and not writing down workings out, not being accurate in electronics etc etc - other students i teach have told me that he argues with other teachers in his other lessons. Any advice on what to do? I keep being told its his aspergers but he knows what is right and wrong and if it was any other student they would be in disiplinary no questions. I dont see why I should have to put up with being treated like this.
