The other day a student was sleeping in my class. I stopped class and told him that he had to keep awake. I gave him suggestions on how to do this. The student jumped out of his chair and told my that he had a medical problem and I didn't care about him. When I got to him as he was trying to leave the building I told him I do care. I explained to him that I have a son with the same disability, I also told him that I'm the kind of person that looses sleep over things like that. we talked awhile and I found out that he was out of medication which was the root of the problem. I gave him a few suggestions to fix the problem and now this student is doing great. Communication is the Key. I've also had simular situation go the other way. Teaching is a never ending battle to communicate.
