Clark Aldrich has an interesting chart on the 'flow of skills':
Here are some of the flows:
1. Instructors might learn from experts, format the information for students, who then become informed practitioners.
2. Experts might mentor practitioners.
3. Practitioners might get promoted to expert.
4. Students might work to get into a class, and get credit for successfully completing it.
5. Peer to peer communities might chew on problems and come to a solution.
What is obvious is the recent focus on eliminating or at least dramatically reducing the entire right side of the chart, the role of instructor and the role of student, while dramatically increasing the areas of overlap between expert and novice (middle left), such as peer-to-peer work and social networking.
