From YouTube Pioneer Sal Khan, a School With Real Classrooms
After some 10,000 online tutorials in 10 years, Sal Khan still starts most days at his office desk in Silicon Valley, recording himself solving math problems for his Khan Academy YouTube channel.
“OK, let F of X equal A times X to the N plus,” he says cheerfully as he begins his latest.
Khan Academy has helped millions of people around the world — perhaps hundreds of millions — learn math, science and other subjects for free. But these days, just one flight of stairs down from his office, there is a real school that couldn’t be more different in form and structure from those online lectures.
