This handy YouTube channel hosts more than , free instructional videos from universities and independent educators like the Khan Academy.
A hoodie-clad year-old with big brown eyes and a mass of jet-black hair, Khan leans back in his chair as he talks, cracking a steady stream of jokes. His desk is made out of old telephone poles and is scattered with books on investing, physics, and heart disease—subjects for upcoming videos. Khan keeps up a breakneck pace of productivity: He has recorded every one of the videos on the site himself and produces up to eight new ones each workday.
But he also frequently goes outside his areas of expertise, hitting Wikipedia, the web, his personal library, and his long list of brainy friends to bone up on new topics until he feels competent. Khan never intended to become an education revolutionary. Talented at math in high school, he initially hoped to be a Richard Feynman-style theoretical physicist, before realizing he was far more likely to make his mark in computers. After finishing at MIT and working for a few Silicon Valley dotcoms, he headed to Harvard Business School in , where he claims his main motivation was to get married.
After business school, Khan went to work for Wohl Capital, a hedge fund, where he researched companies to find solid investments. At Wohl, he learned how to quickly orient himself in unfamiliar territory. He also amassed an epic store of mental trivia. Khan agreed to tutor her on the phone. Because that way she could review the video as many times as she wanted, scrolling back several times over puzzling parts and fast-forwarding through the boring bits she already knew.
A lightbulb went off: Khan realized that remediation—going over and over something that you really ought to already know—is less embarrassing when you can do it privately, with no one watching.
Nadia learned faster when she had control over the pace of the lecture. He also discovered that the state of math education in the country was pretty awful. He began tutoring several other cousins word had gotten around the family: free lessons! Even on simple division questions, they answered tentatively and slowly. Khan wanted to get the kids to the point where they could confidently bark back these answers—they had to have this kind of automatic mental processing before they could handle more-advanced material.

What his cousins needed, he decided, was drilling. He programmed Java modules that would fire questions at them automatically. If they got 10 questions right in a row, the software would push them to the next level, which had harder problems. As a bonus, he could peek at the database online to make sure they were actually doing the practice. Word soon spread to the rest of the world. Khan discovered that thousands of people were watching his videos on YouTube. Some were students mystified by physics, others were adults brushing up on basics before relaunching a stalled college degree.
Khan gradually became more and more absorbed in his site, staying up past midnight crafting new videos and software lessons. Email messages poured in from fans, startling him with their intensity. After dropping to a C in math, Brannan learned enough from Khan to ace his last few high school tests and now plans to pursue a degree in computer science. In , Khan decided to turn his hobby into a full-time job.
Demand had taken off; now tens of thousands of people were watching his videos every month. Khan quickly got to work recording more clips in his closet. His foundation had researched unemployment and found math to be a significant stumbling block. Traditionally, these kinds of videos can be dry and difficult to slog through.
But Khan manages to pull off his lessons with a casual air that keeps the viewer engaged. He never writes a script. Khan also never edits. Either he nails the lecture in a single take or he redoes the entire thing until it satisfies him. Khan suspects there is a hidden power in the fact that he never appears onscreen in his videos.
The only visual is his handwriting, slowly filling the screen. At his desk, he pulls up a YouTube video about how the sodium-potassium pump in a cell membrane works.
What Happens When an Algorithm Helps Write Science Fiction
Several students I spoke to also pointed out that Khan is particularly good at explaining all the hidden, small steps in math problems—steps that teachers often gloss over. Last November , Khan Academy made the jump from hot new website to actual classroom tool. Three schools offered up classes as test subjects—two fifth-grade classes including the one run by Kami Thordarson and two seventh-grade classes. Khan thought he could offer teachers crucial new insight into how students learn.
Normally, of course, teachers fly blind. A dashboard, Khan says, can change all that. In the fall of , flush with the infusion of money from Google and Gates, Khan hired a programmer, Ben Kamens, and a designer, Jason Rosoff, and tasked them with, among other things, building the dashboard. Wrong: They were astounded. But they were completely shocked, as if this had never existed before.
The software even told Cadwell how many minutes the students had worked at home. A look at the data shows that the students seem to advance in spurts: A kid will grind away at a subject, seemingly stuck, until suddenly something clicks and he vaults forward, sometimes going on a tear and mastering several new subjects in a day or two.
When her seventh-grade class arrived last fall, some barely had third-grade math skills. One girl I met in the classroom had advanced an astonishing percent.
