Here's an intriguing idea about teaching. "...providing lots of structure and guidance early on, until the students or workers show that they can do it on their own — makes intuitive sense, it may not be the best way to promote learning." http://ideas.time.com/2012/04/25/why-floundering-is-good/ I had good success teaching my first tango class ever, when I knew almost nothing about the dance and could provide little guidance. (I was the only teacher around, so the job was mine). As I began to know more about the dance, my students had less success learning it.
