All teaching is a head fake. The expression "head fake" comes from football. The quarterback consciously moves his head as if he were going to throw the ball to one player, but then throws it to another. If a skill can be learned, or knowledgeacquired, simply by copying or imitating--then there is no need for teaching. Imitating is often under rated as a powerful part of learning, but true teaching results in new concepts and inspired expression or revisions. Teaching is a process where by students are "tricked" into seeing things differently and then encouraged to re-make the world in a way which is consistent with that new way of seeing.
