What happens to the people who make their livings from teaching, when their jobs are replaced by online courses available for free? All we need is one superb remedial algebra course that can be effectively delivered online and, theoretically, the demand for a zillion remedial algebra courses taught at a zillion community colleges suddenly drops off a cliff. Ask the music business what happens when you can get good stuff for free instead of paying for crap. Daily newspaper journalists learned a similar lesson all too well over the past two decades. The Associated Press business model — licensing the same story to multiple outlets, doesn’t make a whole lot of sense once a single news outlet puts that AP story online for free.

My own daughter is a freshman at a U.C. campus, and has already experienced lectures attended by more than 500 students with sections led by teaching assistants who are utterly uninterested in doing their job. For dollar paid, the value received is questionable, and whenever that kind of situation exists, the status quo is ripe for disruption. (It’s also worth noting, perhaps, that over 60,000 students applied for spots in a freshman class that ended up enrolling only 4,500 applicants, a sign, I think, that the brick-and-mortar university is in no imminent danger of going the way of the dinosaur.)

Education, I’d argue, has always been the most likely sector of society to get transformed by the Internet, because the thing the Internet does better than anything else is distribute information.

“In a classroom, when you ask a question, one student answers and the others don’t get a chance,” Mr. Thrun said. “Online, with embedded quizzes, everyone has to try to answer the questions. And if they don’t understand, they can go back and listen over and over until they do.” Just as a child who falls while learning to ride a bike is not told “You get a D,” but is encouraged to keep trying, he said, online classes, where students can work at their own pace, can help students keep practicing until they master the content. “The goal should be to get everybody to A+ level,” he said

“I wish that the always-available, always-replayable and free nature of this style of learning can help to elevate education/knowledge for all of human kind.”

the great divergence

He found that most had few or no memories of their parents pushing or prodding them or getting involved at school in formal ways. Instead, students described mothers and fathers who set high expectations and then stepped back. “These kids made it!,” Robinson told me. “You’d expect they’d have the type of parental involvement we’re promoting at the national level. But they hardly had any of that. It really blew me away.”

n middle-class households, kids learned to ask critical questions and to advocate for themselves—behaviors that served them well in the classroom.

by as much as eight points on a reading or math test—is by getting them placed in the classroom of a teacher with a good reputation. This is one example for which race did seem to matter: white parents are at least twice as likely as black and Latino parents to request a specific teacher.
