An educator in and out of the classroom for about 40 years. Taught Shakespearean Literature and, later, became an administrator.
My son plays basketball. As a former coach, I can teach his how to place his feet before a 3-point shot, and a lot of other things, but I can't teach him HEIGHT.
I don't believe that a teacher can be TAUGHT to be inspirational or memorable - it's a function of who the person is, how they interact, their confidence, among others.
