The Campus Tsunami - NYTimes.com Online education is not new. The University of Phoenix started its online degree program in 1989. Four million college students took at least one online class during the fall of 2007. But, over the past few months, something has changed. The elite, pace-setting universities have embraced the Internet. Not long ago, online courses were interesting experiments. Now online activity is at the core of how these schools envision their futures. This week, Harvard and the Massachusetts Institute of Technology committed $60 million to offer free online courses from both universities. Two Stanford professors, Andrew Ng and Daphne Koller, have formed a company, Coursera, which offers interactive courses in the humanities, social sciences, mathematics and engineering. Their partners include Stanford, Michigan, Penn and Princeton. Many other elite universities, including Yale and Carnegie Mellon, are moving aggressively online. President John Hennessy of Stanford summed up the emerging view in an article by Ken Auletta in The New Yorker, "There's a tsunami coming." What happened to the newspaper and magazine business is about to happen to higher education: a rescrambling around the Web. Many of us view the coming change with trepidation. Will online learning diminish the face-to-face community that is the heart of the college experience? Will it elevate functional courses in business and marginalize subjects that are harder to digest in an online format, like philosophy? Will fast online browsing replace deep reading? If a few star professors can lecture to millions, what happens to the rest of the faculty? Will academic standards be as rigorous? What happens to the students who don't have enough intrinsic motivation to stay glued to their laptop hour after hour? How much communication is lost - gesture, mood, eye contact - when you are not actually in a room with a passionate teacher and students? The doubts are justified, but there are more reasons to feel optimistic. In the first place, online learning will give millions of students access to the world's best teachers. Already, hundreds of thousands of students have taken accounting classes from Norman Nemrow of Brigham Young University, robotics classes from Sebastian Thrun of Stanford and physics from Walter Lewin of M.I.T. Online learning could extend the influence of American universities around the world. India alone hopes to build tens of thousands of colleges over the next decade. Curricula from American schools could permeate those institutions. Research into online learning suggests that it is roughly as effective as classroom learning. It's easier to tailor a learning experience to an individual student's pace and preferences. Online learning seems especially useful in language and remedial education. The most important and paradoxical fact shaping the future of online learning is this: A brain is not a computer. We are not blank hard drives waiting to be filled with data. People learn from people they love and remember the things that arouse emotion. If you think about how learning actually happens, you can discern many different processes. There is absorbing information. There is reflecting upon information as you reread it and think about it. There is scrambling information as you test it in discussion or try to mesh it with contradictory information. Finally there is synthesis, as you try to organize what you have learned into an argument or a paper. Online education mostly helps students with Step 1. As Richard A. DeMillo of Georgia Tech has argued, it turns transmitting knowledge into a commodity that is cheap and globally available. But it also compels colleges to focus on the rest of the learning process, which is where the real value lies. In an online world, colleges have to think hard about how they are going to take communication, which comes over the Web, and turn it into learning, which is a complex social and emotional process. How are they going to blend online information with face-to-face discussion, tutoring, debate, coaching, writing and projects? How are they going to build the social capital that leads to vibrant learning communities? Online education could potentially push colleges up the value chain - away from information transmission and up to higher things. In a blended online world, a local professor could select not only the reading material, but do so from an array of different lecturers, who would provide different perspectives from around the world. The local professor would do more tutoring and conversing and less lecturing. Clayton Christensen of Harvard Business School notes it will be easier to break academic silos, combining calculus and chemistry lectures or literature and history presentations in a single course. The early Web radically democratized culture, but now in the media and elsewhere you're seeing a flight to quality. The best American colleges should be able to establish a magnetic authoritative presence online. My guess is it will be easier to be a terrible university on the wide-open Web, but it will also be possible for the most committed schools and students to be better than ever.
