Khan Academy founder Salman Khan talks about his new book, The One World Schoolhouse: Education Reimagined, in an interview with MIT Technology Review. Instead of the Prussian model — students march in lockstep through the curriculum — Khan believes technology will make “mastery learning” practical.
Everyone advances at his or her own pace. Don’t try algebra until you know your arithmetic. Spend less time in lectures and more in hands-on problem solving.
Most students can be motivated to learn, if they can go at their own pace, Khan says. “The core reason for students disengaging is that they are frustrated. They’re in algebra class but don’t have a good foundation in pre-algebra or arithmetic.”
Khan Academy is “investing heavily” in analytics, says Khan. “What does a student know? What does a student not know? How effective is the tutorial?” In elementary and middle schools using Khan in the classroom, teachers are very enthusiastic about the real-time learning assessments — more so than the videos.
Online learning will revolutionize higher education and liberate students from ever-rising college costs, Khan says.
Here’s what I think it could look like in five years: the learning side will be free, but if and when you want to prove what you know, and get a credential, you would go to a proctoring center [for an exam]. And that would cost something. Let’s say it costs $100 to administer that exam. I could see charging $150 for it. And then you have a $50 margin that you can reinvest on the free-learning side.
If students can earn credible credits by taking free online classes, the college cartel will be broken, writes Jeff Selingto at the Chronicle of Higher Education. Now universities often reject transfer credits, claiming the quality of instruction doesn’t match their own, he writes.
. . . what happens when students arrive at the registrars’ office with credit-bearing courses from professors at Stanford, Penn, and Princeton? What will the excuse be then to reject the credits—that the courses were free? Such an excuse might finally expose the true reason many colleges refuse to accept transfer credits: They want students to pay them tuition for a class . . .
It all depends on assessment. If there’s a credible, cost-effective way to measure learning, then everything changes.
