I do like his ideas about using freely available internet resources as sources for students' first contact with the material being learned. But it does mean taking the time to determine which sources are reliable and truly of pedagogical value. Which is why once you find a good textbook that works for students I am so reluctant to change. It takes time to assess and field test a textbook for a course. And this would be the same for using internet resources.
Currently, my university is encouraging faculty to consider adopting open educational resources for our courses. Thank goodness our Centre for Teaching and Learning is willing and able to provide some resources to help us curate that freely available content. But it still takes time away from other things I need to be doing. What do I do less of in order to do this?
