from Stephen Downes OLDaily comments on the post The Radical Impossibility of Teaching. Downes mentions that he thinks the teacher is limited to modeling and demonstrating. Once again, I concur with his view of the role of teaching in learning.

The Radical Impossibility of Teaching

I take [this] as a serious question: “Is the whole process of
teaching a paradox? When teachers teach and learners learn,
what is the nature of the causal link between the two, if
any? How does teaching produce learning? Does teaching
produce learning?” I think the causal relationship between
teaching and learning is much less direct than popular
wisdom suggests (which is why on my own account the teacher
is limited to modeling and demonstrating).
