This Company May Hold the Secret to the Future of Education - Victor Luckerson, Time

Whether people are actually learning new languages effectively with Duolingo is still an open question. von Ahn is careful not to oversell the capabilities of the service. The idea that a piece of software could make a person fluent in a foreign language in mere hours is, in his words, “bull—t.” “If you really want to become perfectly fluent, probably what you need to do is move to that country,” he says. “Learning a language is something that takes years.” Still, he says completing all the lessons in a language course in Duolingo is about the equivalent of taking an intermediate-level language course in college. A study commissioned by the company found that people learned as much taking Duolingo lessons in Spanish for 34 hours as they would in a semester of an introductory college class. http://time.com/2902109/duolingo-online-education-moocs/
