Alex Tabarrok reviews why traditional education is getting more expensive; he finds that its productivity has not been able to rise as fast as productivity in other sectors. Online education offers a promising alternative, and he explains how, if done properly, online education can realize productivity gains along many different dimensions. He concludes that online education is disrupting traditional educational forms, and that it is not yet clear what new forms will emerge from this exciting transition.
Alan Ryan views online education as potentially beneficial for students of lower-income families, but he demurs somewhat: As a technology, lectures have mostly been obsolete ever since the spread of the printed book. And the tutorial system as employed at Oxford will not realize many efficiency gains by going online. Additionally, the ability to selectively view the best fifteen minutes of any current professor’s oeuvre bodes ill for the professoriate, whose careers may all become just that short.
Siva Vaidhyanathan criticizes the “hypodermic needle” theory of communication, in which a communicator uses mass media to inject content into a passive audience. He argues that Alex Tabarrok’s lead essay is to some extent guilty of employing this theory. The true value of higher education lies not in injecting information, but in students’ and educators’ interactions. Online education can sometimes duplicate this process, but MOOCs are typically little more than “fancy textbooks.” While they have promise in some areas, we shouldn’t trust the hype.
Kevin Carey argues that the implications of online education are even more radical than Alex Tabarrok’s lead essay might imply. The introductory courses that scale well are almost certain to go fully online soon. Accreditation for online learning can’t be far behind, possibly by way of systems other than the traditional university credit. Little stands in the way of this shift except “habit, convention, and government regulation.” But afterward, the old university system may no longer be solvent.
