Elite universities are throwing open their classrooms' doors to anyone with an internet connection — for free. he company Coursera has teamed up with 16 universities (including Stanford, Duke, and Princeton) to offer more than 100 free online courses to anyone with internet access. They don't want to be left behind in the digital revolution that has already transformed the way we consume news, music, and books. Stanford, Duke, Princeton, and Johns Hopkins are among the 16 universities that have partnered with a newly launched company called Coursera to offer more than 100 free online courses this academic year; MIT, Harvard, and the University of California, Berkeley, are following suit through a nonprofit venture called edX. Now people anywhere in the world can take Stanford's "Introduction to Mathematical Thinking," learn the "Principles of Obesity Economics" at Johns Hopkins, or have Duke University behavioral economist Dan Ariely lead them through "A Beginner's Guide to Irrational Behavior"—all without paying the $50,000 usually required to attend these world-class universities. More than 1 million people from scores of countries have already enrolled in the free classes, which some believe could transform the mission and model of higher education. Anant Agarwal, president of edX, calls it "the single biggest change in education since the printing press."
