Michael McMaster's reference to 'situated learning' and 'learning at the
edge' (technically known as ZPD - the Zone of Proximal Development') comes
from Activity Theory, whose primary expositors are L.S. Vygotsky (Mind in
Society, 1978) and A.N. Leont'ev (Activity, Consciousness and personality,
1978).
There is a listserver where Activity Theory, situated cognition and ZPD is
discussed. It is moderated at the Laboratory of Human Cognition at UCSD
