I have a student in my class that has is very impulsive and has trouble staying focused. I'm fairly certain that he has ADHD, but the parents don't want to hear it and refuse to bring him to a doctor to be tested. His behaviour is manageable, but his marks are suffering because he can't concentrate. The parents have asked me to be 'firm' with him and they made their son promise to try harder. The problem is that I can't force him to focus and I know that he's already trying his best to focus - it's just too hard for him and he doesn't know how. What I am looking for are strategies that I can teach him to improve his concentration skills so that he can actually remember what he is reading and learning in class. Any suggestions?
