Hi Barbara, Ever since the beginning of time, when the first person shared how and how not to attack a wooly mammoth, we have been sharing our experience. If the same mistakes were repeated over and over again, the mammoths would be reading about us instead of the other way around. The idea of attending other classes and observing other teaching techniques is the component of modeling we need to keep focused on. We learn from others both the good and the bad. This gives us a base from which we can select our teaching style. Constant feedback from students and peers will help us to refine our style and be effective in the classroom. No, we don't want to repeat the same mistakes, because then progress is never made. Gary
