Too many of our teachers have had to suffer through one-off, lecture-style "sit and get" professional development sessions. We know this model of learning doesn't work for students. Well, no surprise, it doesn't work for teachers either. It can be ruthlessly boring and far removed from the context-specific challenges they face in their classrooms. Among all professions, it would seem that educators should be especially good at effective adult learning, but too often this is not the case.
