Wired – How Khan Academy Is Changing the Rules of Education

For years, teachers like Thordarson have complained about the frustrations of teaching to the “middle” of the class. They stand at the whiteboard, trying to get 25 or more students to learn the same stuff at the same pace. And, of course, it never really works: Advanced kids get bored and tune out, lagging ones get lost and tune out, and pretty soon half the class isn’t paying attention. Since the rise of personal computers in the early ’80s, educators have hoped that technology could solve this problem by offering lessons tailored to each kid. Schools have blown millions, maybe billions, of dollars on sophisticated classroom technology, but the effort has been in vain.

Khan’s videos are anything but sophisticated. He recorded many of them in a closet at home, his voice sounding muffled on his $25 Logitech headset. But some of his fans believe that Khan has stumbled onto the secret to solving education’s middle-of-the-class mediocrity. Most notable among them is Bill Gates, whose foundation has invested $1.5 million in Khan’s site. “I’d been looking for something like this—it’s so important,” Gates says. Khan’s approach, he argues, shows that education can truly be customized, with each student getting individualized help when needed.

Not everyone agrees. Critics argue that Khan’s videos and software encourage uncreative, repetitive drilling—and leave kids staring at screens instead of interacting with real live teachers. Even Khan will acknowledge that he’s not an educational professional; he’s just a nerd who improvised a cool way to teach people things. And for better or worse, this means that he doesn’t have a consistent, comprehensive plan for overhauling school curricula.

Whatever Khan’s limits, his site has become extremely popular. More than 2 million users watch his videos every month, and all told they answer about 15 questions per second. Khan is clearly helping students master difficult and vital subjects. And he’s not alone: From TED talks to iTunes U to Bill Hammack the Engineer Guy, new online educational tools are bringing the ethos of Silicon Valley to education. The role these sites can (or should) play in our nation’s schools is unclear. But classes like Thordarson’s are starting to find out.
