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.

东道主的对手阿根廷队在此次世界杯中也有很大的机会。一支以梅西为主的队伍都会在最后大放异彩,但是当你在队伍中增添类似塞尔吉奥·阿奎罗(Sergio Aguero)、冈萨罗·伊瓜因(Gonzalo Higuan)和埃泽奎尔·拉维奇(Ezequiel Lavezzi)这样的队员的话,那么它将是这届世界杯上最具有进攻打法的球队了。同理,乌拉圭的进攻三人组——路易斯·苏亚雷斯(Luis Suarez)、埃丁森·卡瓦尼(Edinson Cavani)以及迪亚戈·弗兰(Diegol Forlan)同样拥有同等的实力,能对世界上任何一支球队比赛时进球,不过,他们所在队伍中其他人的实力是否足够强还让人存疑。

Rogers, unhappy with the turn of events, decided to leave the show after the first three seasons. The breach of contract led to a multi-million dollar lawsuit.

You could say Rogers got the last laugh, but since M·A·S·H went on for eight more seasons and Rogers' never reached the same career success again, the last laugh might be a relative concept.
