In a conversation on LinkedIn, one person asked, "What are the characteristics of an effective teacher?" I read quite a few excellent remarks that describe what such a teacher does to be effective.
Returning to my original premise: great teachers do not teach. They stack the deck so that students have a reason to learn and in the process can't help but learn mainly by teaching themselves. This knowledge then becomes permanent and cherished rather than illusory and irrelevant.
