It's amazing how much we learn by standing in front of a group of students and trying to explain something. Anything. In an effort to relate textbook concepts to interested individuals, we find ourselves reaching deep into our memory bank and extracting practical examples that may have long since been forgotten and discarded. The process of remembering gives rise to new expressions and creative ideas, and as we endeavor to clarify and simplify complex ideas, we share personal experiences. There's something special that happens when we tell stories and recall our past. The introspective and reflective come alive, and more often than not, the process of telling and explaining allows for new insights...into ourselves and our subject matter. It's like taking a familiar painting out of a dark room into the light. We know the subject well, but when we take it out to examine it, we always see new features and subtleties that we can appreciate. That's the beauty of learning by teaching.
