The first mistake of many online classes and the majority of MOOCs (so far) is that they try to replicate something we do in face-to-face classes, mapping the (sometimes pedagogically-sound, sometimes bizarre) traditions of on-ground institutions onto digital space. Trying to make an online class function exactly like an on-ground class is a missed opportunity. There's a lot that happens in F2F classrooms that just can't be replicated in an online environment, and that's okay. Better to ask ourselves what can be achieved online and what sorts of classes (or learning experiences) we can construct to leverage the potentials of the specific interface or community.
