I love this idea — of an “Unlearning Curve”…

One of the most challenging pieces of figuring out how to move education forward in a systemic way is “unlearning curve” that we teachers and educators have to go through to even see the possibilities that lay before us. So much of our traditional thinking about personal learning and classroom practice is being challenged by our ability to publish and connect and collaborate primarily because of the opportunities afforded by the Read/Write Web. For instance, in a world where literally any place can be a classroom, we have to unlearn the comforts of four walls that we’ve become accustomed to. When we can share our work with wide audiences, we need to unlearn the idea that student writing and projects are simply ways to assess what they know…

This doesn’t just apply to educators but to anyone who has been successful in an industry which is being transformed by technology. Broadcast TV, for example.
