Thanks for getting us started, Susie.
One of the luckiest days of my beginning teaching was to be placed in an open space classroom with five other teachers. I know, I know, no one likes this set-up and all open space classrooms have been walled up. But for me it was liberating, interesting, fun and oh so full of learning. I watched pros in action and watched beginners struggle. I struggled, the pros struggled--although much less than I did and I gained more knowledge about teaching than I ever thought possible. We discussed our lessons and why they worked or did not, fed off each others' ideas, and supported each other through a miserable time with a leader who could not lead, did not lead, and was more than a bubble off-center (think of a level).
Susie's discussion about learning to teach made me realize how very fortunate I was. And besides that, three of those teachers who taught me to teach are still friends after 37 years!!
