Hi Richard, I loved reading the article you linked and it reminded me of my return to higher education for graduate school in the mid-90s. When I completed my bachelor's degree in the early 80s there were library cards and in the mid-90s only computer screens. I had no idea what had happened and how I would ever find a book again :) I agree that new technlogy has affected the flow of perception and no longer does the logical flow seem linear but webbed and multilayered. I would suggest, however, that while those are changes, there is a different flow and percetion that we as educators need to constantly work through in order to fully integrate new approaches that support new ways of thinking in our courses.
