My district has begun to make a big push for the implementation of Professional Learning Communities (PLC's). Now I am fully aware of what PLC's are and how they are supposed to function within a school. Can anyone share with me their experience with them? How have you set time aside for them? How do you monitor them? Do your teachers think they effective in terms of professional growth? What are the positives and negatives? Can you tell me how you got your teachers to "buy into" the concept?
