This article by the University of Utah discusses Lindeman's and Knowles's theories on adult learning. Andragogy uses the teacher differently from pedagogy: the teacher in an adult learning environment becomes a facilitator instead of the knower. I think this is an important distinction to make for people who go from teaching children to teaching adults. There are two of these people on my team at work. One taught third grade and one taught sixth grade, and both of them tend to try to put the instructor in the knower's position instead of the facilitator's position. They have to catch themselves often and rework some instruction to be more student-focused instead of content-focused. 8/10
