Gregory Nagy, a professor of classical Greek literature at Harvard, is a gentle academic of the sort who, asked about the future, will begin speaking of Homer and the battles of the distant past. At seventy, he has owlish eyes, a flared Hungarian nose, and a tendency to gesture broadly with the flat palms of his hands. He wears the crisp white shirts and dark blazers that have replaced tweed as the raiment of the academic caste. His hair, also white, often looks manhandled by the Boston wind. Where some scholars are gnomic in style, Nagy piles his sentences high with thin-sliced exposition. (“There are about ten passages–and by passages I simply mean a selected text, and these passages are meant for close reading, and sometimes I’ll be referring to these passages as texts, or focus passages, but you’ll know I mean the same thing–and each one of these requires close reading!”) When he speaks outside the lecture hall, he smothers friends and students with a stew of blandishment and praise. “Thank you, Wonderful Kevin!” he might say. Or: “The Great Claudia put it so well.” Seen in the wild, he could be taken for an antique-shop proprietor: a man both brimming with solicitous enthusiasm and fretting that the customers are getting, maybe, just a bit too close to his prized Louis XVI chair.
Nagy has published no best-sellers. He is not a regular face on TV. Since 1978, though, he has taught a class called “Concepts of the Hero in Classical Greek Civilization,” and the course, a survey of poetry, tragedy, and Platonic dialogues, has made him a campus fixture. Because Nagy’s zest for Homeric texts is boundless, because his lectures reflect decades of refinement, and because the course is thought to offer a soft grading curve (its nickname on campus is Heroes for Zeroes), it has traditionally filled Room 105, in Emerson Hall, one of Harvard’s largest classroom spaces. Its enrollment has regularly climbed into the hundreds.

Rather than writing papers, they take a series of multiple-choice quizzes. Readings for the course are available online, but students old-school enough to want a paper copy can buy a seven-hundred-and-twenty-seven-page textbook that Nagy is about to publish, “The Ancient Greek Hero in 24 Hours.”

At one extreme, edX has been developing a software tool to computer-grade essays, so that students can immediately revise their work, for use at schools that want it. Harvard may not be one of those schools. “I’m concerned about electronic approaches to grading writing,” Drew Gilpin Faust, the president of the university and a former history professor, recently told me. “I think they are ill-equipped to consider irony, elegance, and . . . I don’t know how you get a computer to decide if there’s something there it hasn’t been programmed to see.”
…
The answer is c). In Nagy’s “brick-and-mortar” class, students write essays. But multiple-choice questions are almost as good as essays, Nagy said, because they spot-check participants’ deeper comprehension of the text. The online testing mechanism explains the right response when students miss an answer.
…
It is also under extreme strain. In the mid-nineteen-sixties, two economists, William J. Baumol and William G. Bowen, diagnosed a “cost disease” in industries like education, and the theory continues to inform thinking about pressure in the system. Usually, as wages rise within an industry, productivity does, too. But a Harvard lecture hall still holds about the same number of students it held a century ago, and the usual means of increasing efficiency–implementing advances in technology, speeding the process up, doing more at once–haven’t seemed to apply when the goal is turning callow eighteen-year-olds into educated men and women. Although educators’ salaries have risen (more or less) in measure with the general economy over the past hundred years, their productivity hasn’t. The cost disease is thought to help explain why the price of education is on a rocket course, with no levelling in sight.

King rattled off three premises that were crucial to understanding the future of education: “social connections motivate,” “teaching teaches the teacher,” and “instant feedback improves learning.” He’d been trying to “flip” his own classroom. He took the entire archive of the course Listserv and had it converted into a searchable database, so that students could see whether what they thought was only their “dumb question” had been asked before, and by whom.
