It describes how collaborative projects, virtual field trips, competitions, and wikis can be used to create co-created content and harness the collective wisdom of groups. Different levels of interactivity and engagement are outlined, from passive to evolving learning communities. Examples are given of schools participating in content-driven collaborations around environmental issues, civic responsibility, and connectedness. Tools that facilitate this type of collaboration are also mentioned.
