I'm betting on social learning platforms as a lever for improvement at scale in education. Instead of a classroom as the primary organizing principle, social networks will become the primary building block of learning communities (both formal and informal). Smart recommendation engines will queue personalized content. Tutoring, training, and collaboration tools will be applications that run on social networks. New schools will be formed around these capabilities. Teachers in existing schools will adopt free tools yielding viral, bureaucracy-cutting productivity improvement. In the coming decade, most middle and high schools will adopt some version of 1:1 technology, online learning will play an increasing role, and learning experiences will be conducted and coordinated on social learning platforms. While adoption won't be simple and smooth, it will cut through the typical barriers that block other reforms.
