learning vs. teaching redux

this quote goes back to a weeks-past discussion about learning and teaching, but I ran across an interesting quote from homeschooling/unschooling proponent John Holt this evening looking for info on my end of the semester project

"The most important thing any teacher has to learn, not to be learned in any school of education I ever heard of, can be expressed in seven words: Learning is not the product of teaching. Learning is the product of the activity of learners"
