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.
