Via elearnspace, a link to the Collaborative Learning Environments Sourcebook.
As described from their site…
This is a sourcebook for academics and students who want to develop collaborative learning environments (or communities of practice) in which lecturers, students and others can work together to create new knowledge while learning new skills. Click on the links on the left to browse through the book. The book is currently in the process of being (collaboratively) developed, but already contains quite a lot of useful material. Below are details of the larger project that the book is a part of.
Looks like this might prove useful for the ongoing search for community tools….
Need to spend a bit of time there…
