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.
