Excerpt
Teaching Introduction to Sociology is almost second nature to Mitchell Duneier, a professor at Princeton: he has taught it 30 times, and a textbook he co-wrote is in its eighth edition. But last summer, as he transformed the class into a free online course, he had to grapple with some brand-new questions: Where should he focus his gaze while a camera recorded the lectures? How could the 40,000 students who enrolled online share their ideas? And how would he know what they were learning?
In many ways, the arc of Professor Duneier’s evolution, from professor in a lecture hall to online instructor of tens of thousands, reflects a larger movement, one with the potential to transform higher education. Already, a handful of companies are offering elite college-level instruction — once available to only a select few, on campus, at great cost — free, to anyone with an Internet connection.
Moreover, these massive open online courses, or MOOCs, harness the power of their huge enrollments to teach in new ways, applying crowd-sourcing technology to discussion forums and grading and enabling professors to use online lectures and reserve on-campus class time for interaction with students.
The spread of MOOCs is likely to have wide fallout. Lower-tier colleges, already facing resistance over high tuition, may have trouble convincing students that their courses are worth the price. And some experts voice reservations about how online learning can be assessed and warn of the potential for cheating.
MOOCs first landed in the spotlight last year, when Sebastian Thrun, a Stanford professor, offered a free artificial-intelligence course, attracting 160,000 students in 190 nations. The resulting storm of publicity galvanized elite research universities across the country to begin to open higher education to everyone — with the hope of perhaps, eventually, making money doing so.
The expansion has been dizzying. Millions of students are now enrolled in hundreds of online courses, including those offered by Udacity, Mr. Thrun’s spinoff company; edX, a joint venture of Harvard and the Massachusetts Institute of Technology; and Coursera, a Stanford spinoff that is offering Professor Duneier’s course and 200 others.
No one knows just how these massive courses will evolve, but their appeal to a broad audience is unquestioned: retirees in Indiana see them as a route to lifelong learning, students in India as their only lifeline to college-level work.
