Rick, to add a related by quite distinct source to this approach to
learning, I recommend a book from John Seely Brown's Xerox group
called "Situated Learning". I'll dig up the author's name if you
can't locate the book and want the reference. (I'm travelling right
now.)
The book locates learning within social systems - situated - and
locates learning as occurring "at the edges" and by means which will,
I think, expand the idea of implicit. For instance, it is not
required in this approach that the implicit be made explicit for
learning to take place. It is a much more emergent approach to
learning.
