Web 2.0 has brought an extensive - and ever growing - collection of applications that are widely used by children and adults. Are they a threat to schools apps that just need to be integrated into the existing school program or a basis for school transformation? This session will be based on the CoSN/MacArthur Foundation sponsored project dealing with Web 2.0 and will focus on the challenge and opportunities that Web 2.0 presents to school leaders. It will also give a “sneak preview” of a forthcoming CoSN service “Leading with Web 2.0.”
