Hi Glenn:
Good for you. Many seasoned teachers do not use journals.
Those that do actually end up helping their students through the process of reflection, contemplation, self examination, and observation. As time goes by, better teachers begin to look at their classes differently than when they first began. "I actually said that!" might be the expression several years down the road. Boy, you couldn't purchase that kind of depth of understanding. Good luck!
