Assuming the lecture format to be the Gold Standard for imparting knowledge, technologies like Tegrity and iTunes U serve primarily to fix deficiencies in it. The lecture format worked in an era of low mobility, small classes, few distractions. An instructor had all the time in the world to lecture, elaborate, explain, and answer all the questions of a small number of students who did not have to rush off to work, attend to families, deal with huge course load and indulge in entertainment and other distractions. A lot of things have changed since the lecture format was invented and refined. The nature and pace of life has changed dramatically, and so has the quantum of knowledge available and required to be ingested and digested. The lecture format does not work any more. Yes, the world cannot be changed in a hurry. Yes, the paradigm shift required is so huge that academic institutions and their associated structures as we know them may need to crumble and an entirely new way to educate developed. Are we ready for this? And if not, and if the existing format is so badly broken that it does little good, how long should we remain in a state of voluntary delusion?
Until we call it as we see it, repeatedly, at every forum, and through varied voices, the best we can hope for is series of BandAids of ever increasing complexity. And which will, in fact, lock us into a broken paradigm, eventually leaving us worse off than we already are.
I shudder to think of what is yet to come.
