I too have had some tough kids, the kind you think about dream about getting sick for a week or perhaps even moving away. They are the kinds of kids who impact group dynamics or who take lots of teaching energy. Some say there are more of those kids these days. I agree that WE, as teachers, can make a difference if we set the tone, be a mentor, and try to connect with the student. We need to take these kids as our personal challenge and expect them to succeed.
