Teachers are going to either wear new hats or be irrelevant to students. Becoming irrelevant may be harmful to the students because they need some guidance in their "free agency". At least they need it until they can ride to wherever they want to go without us. Ultimately, we must marginalize our role in their learning lives by empowering them in theirs. When they learn how to learn I believe that is a teacher's greatest reward. Gratitude is great, but you really cannot expect it, else it would not be gratitude.
