I agree with Howard Rheingold's contention that the dynamics of social/collective action can be multiplied by the use of communications technologies... like cell phones. His 2002 book: Smart Mobs, set the stage for the recently released TED Talk he gave three years ago. It's 18 minutes of information that is of great importance to those actively creating the future of education.
In a more complete screencast, Howard uses images and voice to teach about cooperative strategies. If you have the time, see how the work of "smart mobs" are creating the potential for a more collaborative and less competitive future. The Cooperation Commons seeks to model this work in sharing research and resources on this topic. Key quote: "The most important new technologies will not be hardware or software, but social practices."
