Emerging Roles of Teachers

Is the Role of the Teacher as the "Knowledge Authority" in Danger in an ICT-Learning Setting?
Stephen Downes dug up this article from earlier in the year, covering the shift in teaching from "sage on the stage" to "guide on the side". It's focused on the influence of educational technology and elearning, but shouldn't all teaching be moving in the same direction? Only the most pompous educators would claim that they are the keepers of all knowledge and are transmitting it to their students. There are Grade 8 students right now who know twice as much about Egypt, dinosaurs or military technology than their teachers do, and they know how to find out more about whatever topic catches their interest. This short article lists the new (and probably more effective) roles of the teacher: tutor, learner, collaborator, developer, researcher. That's the kind of teaching I would enjoy.
