Hi, thanks for the replies, and Alexander that intute link is very cool. Hmm, 'consciously constructivist approach' that would be an interesting class in philosophy! I teach in a Liberal Arts institution in the states, a tradition not as common elsewhere in the world. The specific discipline is not as important as the process, the learning to learn. Most of the jobs our students will be working have not been created yet, so the importance of a philosophical foundation to life long learning is critical. WiziQ is an excellent example of an emergent paradigm in informal and self-directed learning, and one slowly shaking the foundations of the traditional educational institution, precisely because of a shift in the epistemological foundation.
