This is an interesting subject. As I research more, I will post the resources and add some commentary.

First, a few observations about Learning itself, from How People Learn:

• Learning occurs in context
• Learning is active
• Learning is social
• Learning is reflective

A really great report about Talent crisis by Deloitte has a excerpt from Lexis-Nexis on how people learn most effectively:

• 67% When working together with a colleague on a task
• 22% When doing own research
• 10% When a colleague explains something personally
• 2% Through a manual or textbook

This brings up interesting possibilities on setting up Learning Collaboratories:

• We need to see it with a few mentors whom people can go to
• We need change the ratio of class room based training to project based training, where people actually produce something
• We need to design projects in such a way that people are forced to do their own research
