just came from a 3 day PD session. it was not very effective imo (due to content not due to instruction). It was lead by two women who currently are teachers in my state. I went to another session last summer, also lead by two teachers. these look like pretty "sweet" gigs (as my kids would say). do any of you do this in the summer? how does one get involved? is the pay worth it? as always, thanks in advance for your reply.
