I can’t speak for other parents, but if I had to speculate, it would probably be better communication between parents and teachers. Of course, this is asking a lot of our teachers because there just isn’t any time built into the school day for it. And in many cases, the classrooms are so overcrowded that it is hard to be in touch with everyone after hours.
I do think that teachers who do communicate with parents regularly do themselves a big favor in the long run. Teachers who offer to communicate through E-mail are becoming more common, which is a step in the right direction. If your child’s teacher does, please remember to be respectful of his or her time and only E-mail when you have a real question or concern about your child.
