Hi Mitch: Life and learning is all change. Physiologically, change (adaptation) is partly how we define ourselves as "living". I think the map metaphor doesn't necessary mean different maps but simply that we need to understand our "center", what we believe, know and don't know, dseire and aspire to be. And I think really, this is a life-long process. I think each class provdes a learning-lab for our growth and maturing as teachers, if we approach these experiences with a desire to grow, and benefit, and be better at what we do. Regards, Barry
