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

房地产经纪公司莱坊(Knight Frank)的数据显示,今年第一季度,香港豪宅租金同比下跌5.2%,跌幅超过内罗毕以外的任何其他城市。就在去年9月价格下跌之后,运动品牌阿迪达斯(Adidas)在香港租入了一间1.3万平方英尺的店铺,租金相比上一个租户、配饰品牌蔻驰(Coach)低了22%。

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.

Sylvester Stallone, shuffling into the wise old trainer role, gives perhaps the loosest, warmest performance of his career. Michael B. Jordan, as Adonis Johnson, Rocky’s protégé (and the illegitimate son of his onetime rival and long-lost friend, Apollo Creed), continues his emergence as one of the vital movie stars of our moment. As for Mr. Coogler, with his second feature as a director he proves himself to be a true contender. (Read the review)
