David Evans usually teaches about 50 students in one of his computer science classes at the University of Virginia. In February, he offered a free course on how to build a search engine, and 94,000 people signed up. So many students would never fit in a lecture hall in Charlottesville, nor be allowed in without paying, but that’s no concern at Udacity, the digital university where Evans, an associate professor on leave from U.Va., is teaching. The idea, he said, is to make “high-quality higher education available to people who wouldn’t have the opportunity to come to U.Va., and that’s the vast majority of the world.”
