Anant Agarwal: Why massive open online courses (still) matter
In the spring of 2012, Anant Agarwal, a professor of computer science at MIT, taught a course called “Circuits and Electronics.” As usual, it was MIT-level challenging, requiring knowledge of differential equations and calculus. Unlike in the past, though, the course enrolled 155,000 students from 162 countries around the world.
Agarwal holds the Guinness World Record for the largest microphone array, and was named one of Forbes' top education innovators in 2012. Find him on Twitter at @agarwaledu.
