In many schools and even states, it's been, rather, a movement to block and bust: no blogs, no cell phones, no IM. We take away the powerful social technologies our kids are already using to learn and, in doing so, tell them their own tools are irrelevant. Or, instead of using the complex and challenging phenomenon of a site such as Wikipedia to teach the realities of navigating information in this new world, we prohibit its use. In fact, at this writing, the U.S. legislature is in the process of deciding whether schools and libraries should have access to any of the potential of the Read/Write Web at all. When you read this, blogs and wikis and podcasts (and much more) may be things that students (and teachers) can access and create only from off-campus.
