Curt Bonk explores an interesting theme - teachers as concierges: "We need to push students into the many learning possibilities that are ripe for them now. Concierges sometimes show you things you did not know were available or possible. Teachers as concierges can do the same things."
The theme is somewhat similar to what I presented as curatorial teaching. Both approaches emphasize the importance of educator expertise as a means of directing learners to important resources and ideas without compromising their "wayfinding" skills in complex environments.
