Reclaiming The American Dream VI: The (Other) Lessons of Khan Academy

Howard Husock
This article is more than 6 years old.

To say that Khan Academy has important lessons to offer is to state the obvious. The Mountain View-based internet teaching institution—which has grown from founder Salman Khan’s individualized YouTube math lessons for his 7th grade niece to a worldwide phenomenon—offers thousands of free, plain-spoken online courses, from algebra to biology. But there are even broader lessons to be taken from the astounding success of Sal Khan, winner of the Manhattan Institute’s $100,000 2014 William E. Simon Prize for Lifetime Achievement in Social Entrepreneurship. Indeed, the lessons extend well beyond education

"Well, I believe I am a feminist because I believe that women deserve the same rights as men in every aspect of our economy and our society, here at home and around the world," Clinton said to applause. "You know, I've devoted a lot of my public life to advocating for women's rights being human rights, and making the case that we have to do everything we can, through laws, regulations, culture, to change the still-existing stereotypes that hold women back."

In the past five years, China's exports of goods grew at an annual average of 6.5 percent, with its share in the global market rising form 10.4 percent in 2010 to about 13.2 percent in 2015, faring much better than major global economies. Service trade grew over 13.6 percent each year, marking the world's second largest service trader.

The story of Khan Academy’s start and growth is dramatic. Sal Khan, New Orleans-born and MIT-educated, was working in the finance industry as a hedge fund analyst when, in 2004, he learned that his niece, Nadia, needed help with algebra. He began sending her his own clear, step-by-step illustrated lectures (Khan himself did not appear) via YouTube. That allowed other web users to use the same lessons. The teaching of Khan—a complete outsider to education or education reform—went viral, ultimately catching the eye of Bill Gates, whom Khan learned was helping his own children with lessons first meant for Nadia. Khan eventually attracted $15 million-plus in philanthropic support from the Bill and Melinda Gates Foundation, Google , venture capitalist John Doerr, and others accustomed to the idea that radical newcomers might be worth investing in. Such funding allowed Khan to give up his day job and start Khan Academy, with a forthright, undeniably ambitious goal: a free world-class education, for anyone, anywhere.

A photographer and worker at the Minolta camera company, Hiroshi made the selfie stick because he and his wife were unable to take pictures of themselves during a trip to Europe. (When he asked a boy to take pictures of them, the boy ran off with the camera.)

D'ALOISIO HAS BEEN quoted opining that 'time is the new currency.' It's the driving notion behind Summly. It's also a strangely wise observation from a 17-year-old. At that age, many of us had more time on our hands than we knew how to fill without plummeting into severe boredom. It's easy to forget-conversing over lunch in a London caf钼 or strolling through the Tate Modern-that D'Aloisio was born in 1995 and has not yet graduated from high school. Or that he still lives in his childhood bedroom, in a cozy upper-middle-class home. As I chat with his parents, he excuses himself to work on his computer. Slouching down the hall in his stocking feet, hems of his skinny jeans brushing the hallway carpet, it is the most kidlike you will ever see him.
