A função de “teaching” em “video-driven teaching method” (ITA 2013)
Reboot the School
SALMAN KHAN’S YOUTUBE LESSONS HAVE ALREADY MADE HIM A GEEK CELEBRITY.
NOW HE WANTS TO REINVENT HOMEWORK, BANISH CLASSROOM LECTURES—AND MAYBE SAVE EDUCATION.
By Kayla Webley
1 Fifth-graders at Eastside College Preparatory School in East Palo Alto, Calif., sit at their
desks with netbooks. They're in the middle of a math lesson, listening as a teacher explains how to
convert percentages to decimals. "If we get rid of the percent sign, we just have to move the
decimal sign two places to the left," the instructor says. Pens scribble across notebooks.
5 Eleven thousand miles away in Accra, Ghana, students at the African School for Excellence
are studying logarithms. Their teacher is the same one firing off math tips in California–both groups
of kids are learning by watching online videos. While the screen shows a march of equations and
diagrams, the students never actually see the face of the lecturer. There's just a voice, deep, patient
and unrehearsed—think NPR host crossed with Mister Rogers. His inflection rises at times to
10 underscore a point or when he gets really excited. "Math is not just random things to memorize and
regurgitate on a test next week," he says. "It's the purest way of describing the universe!"
The voice belongs to Salman Khan, a 35-year-old hedge-fund manager turned YouTube
professor to millions around the world. Thanks to his Khan Academy, an online repository of some
3,250 digital lectures, he has become a celebrity to techies, educators and uncounted high
15 schoolers cramming for the AP biology test. His 18-minute discourse on the Krebs cycle and cell
metabolism has been viewed more than 675,000 times.
But Khan isn't satisfied with being the most famous teacher ever to appear on a Web
browser. He believes he has stumbled onto a solution to some of education's most intractable
problems, with his video-driven teaching method at its heart. He wants to fundamentally change the
20 role of teachers in the classroom—and redefine the concept of homework along the way. And he
has persuaded Bill Gates, Google's Eric Schmidt and a minor constellation of other tech billionaires
to back this quest.
Education reform is notoriously difficult. K-12 schools are debating everything from teacher
evaluations to standardized tests, with no consensus in sight. Universities, meanwhile, are
25 confronting massive budget cuts and new kinds of competition—as dramatized by the recent turmoil
at the University of Virginia. Its board fired the president amid worries that UVa wasn't keeping up
with change and embracing online education fast enough, then rehired her 16 days later after a
backlash from students and faculty.
At all levels, there's plenty of skepticism about any tech-centric approach to teaching. An
30 estimated $65.7 billion was spent in the U.S. last year on education technology, according to
research firm Gartner. But many educators say there is little concrete proof of its benefits.
Khan is already butting up against veteran teachers nervous about their roles in his brave
new classroom. But the biggest obstacle of all may be Khan himself. For all his grassroots fandom
and Silicon Valley cred, he's not an educator, and he's never worked with children. Are parents and
35 teachers ready to upend hundreds of years of precedent about how basic subjects are taught on the
word of a guy who has spent more time analyzing financial statements than standing before a
blackboard?
