Hi Harold, really enjoyed your post. Just wanted to pick up on the image you use to describe apprenticeship vs training vs social learning. The image suggests that apprenticeship learning is not social. Is this the case? I had always felt that apprenticeship learning is social and networked (if only on a small scale) and is at the root of how we learn and share. Thought this article on cognitive apprenticeship is useful: http://www.21learn.org/archive/cognitive-apprenticeship-making-thinking-visible/
