From Kineo.com - free thinking :
This rapid guide explains:
-Why you should establish a learning community
-The benefits learning communites can deliver
-The critical success factors involved
-The role of the facilitator / moderator
-The barriers and how to overcome them
While Kineo obviously tries to sell their services - and who could blame them for that? - the free thinking part of their website is well structured and sufficiently open and generic to interest even those who would not need to use them. A good example with this guide -which details the way they implement Learning Communities using Moodle, but targets the key points whether or not using Moodle as the technology to implement LC.
