Alex Tabarrok’s Cato Essay On “Why Online Education Works”

 classroom velkr0 via Compfight

Economist Alex Tabarrok from the Marginal Revolution blog writes a lead essay recently for the Cato Institute about “Why Online Education Works.” He also created a new online education platform called MRUniversity.com with his fellow-economist and co-blogger at Marginal Revolution. He said their first course in Development Economics showed them they could teach a full course online in less than half the lecture time required in an offline course because they don’t need to repeat themselves in lectures.

Tabarrok has many smart things to say in this Cato essay and you can join the discussion at Cato Unbound along with other commentators who have responded (a counter-argument by Siva Vaidhyanathan, who is the Robertson Professor in Media Studies and Chair of the Department of Media Studies at the University of Virginia; some skepticism by Alan Ryan who is the former Warden of New College, Oxford, and a frequent commentator on developments in liberal education; and Kevin Carey, director of the education policy program at the New America Foundation, agrees with Tabarrok’s direction and takes it further.)

Tabarrok writes:

Oxford University was founded in 1096, Cambridge in 1209. Harvard, a relative newcomer, was founded in 1636. Other than religions, few institutions appear to have maintained their existence or their relative status for as long as major universities. And few institutions, notably again other than religions, have seen so little change. Oxford in 2012 teaches students in ways remarkably similar to Oxford in 1096, seated students listening to professors in a classroom.

I see three principle advantages to online education, 1) leverage, especially of the best teachers; 2) time savings; 3) individualized teaching and new technologies.

Leverage

The importance of leverage was brought home to me by a personal anecdote. In 2009, I gave a TED talk on the economics of growth [1]. Since then my 15 minute talk has been watched nearly 700,000 times. That is far fewer views than the most-watched TED talk, Ken Robinson’s 2006 talk on how schools kill creativity [2], which has been watched some 26 million times. Nonetheless, the 15 minutes of teaching I did at TED dominates my entire teaching career: 700,000 views at 15 minutes each is equivalent to 175,000 student-hours of teaching, more than I have taught in my entire offline career.[1] Moreover, the ratio is likely to grow because my online views are increasing at a faster rate than my offline students.

… As my experience with TED indicates, it’s now possible for a single professor to teach more students in an afternoon than was previously possible in a lifetime…
