For fours years I have taught a virology course at Columbia University and have posted videos of each lecture on my website, virology.ws, and at iTunes University. Nearly 100,000 individuals have subscribed to my virology course at iTunes University. Now Columbia has signed an agreement with Coursera, and on 1August, my Virology course will become the fourth course from Columbia University to be offered as a MOOC (massive open online course). The virology course will consist of short videos with embedded questions, weekly assignments, and a final exam.
