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

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.

The value of goods that crossed international borders last year fell 13.8 per cent in dollar terms — the first contraction since 2009 — according to the Netherlands Bureau of Economic Policy Analysis’s World Trade Monitor. Much of the slump was due to a slowdown in China and other emerging economies.

1. 碧昂斯(Beyoncé),《碧昂斯》,Parkwood Entertainment/Columbia。这张专辑是继去年的平淡后的一次突击,是碧昂斯的力作,它光彩夺目地展示了充满情感的统治力、精良的制作、欲望的放纵与女性主义的力量(不一定是按这个顺序),在漫长而充满众多娱乐的一年里一直令人关注。她的歌唱与她的态度一样,极为自信而又充满细节;她所传达的信息复杂而又清晰。这是高端的流行乐,拒绝曲意逢迎。
