I know right.
Every effective teacher I know, knew how to talk about teaching, knew how and the importance of looking at data, knew how to evaluate what strategies were effective, how to talk to other teachers about their strategies. How to reflect and make changes.The importance of collaboration. Ever effective teacher I know has been doing this for YEARS.
These teachers never needed a formal PLC program, training, and implementation...it's the crappy teachers, who never want to talk about the meat and potatoes of teaching. So now we have a program devoted to them.
