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

“我们希望这份榜单会让大家采取措施保护自身的网络安全。”

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.

Big banks have more or less given up on trying to retain people with higher pay. Ever since the financial crisis it has been clear that if you want to get seriously rich, you go to Silicon Valley.

啊,美国电话电报公司的命真好:同史蒂夫?乔布斯的关系最好,拥有iPhone的独家运营权(现在是如此),还是iPad的运营商之一。一切都对它有利,可为什么股票没有猛涨呢?截至4月1日,今年苹果公司的股价已经飙升109%,标准普尔指数也上升了41%。美国电话电报公司的股票呢?下跌了2%。问题在于发展,或者说缺乏发展:无线业务已经饱和,发展甚微,而占销售额25%的有线电话业务却出现萎缩。除非其高速互联网业务,或者iPad促使新的无线业务实现增长,否则其股票在华尔街将会继续遭受打击。

'Fruitvale Station' represents another remarkable feature debut, by the director Ryan Coogler. Its subject matter-the fatal shooting of Oscar Grant, a black, unarmed 22-year-old by a white transit cop in Oakland, Calif.-might have made a documentary. Mr. Coogler had the better idea of exploring it as a dramatized, and to a considerable extent fictionalized, account of the day in Oscar's life that preceded his death. He's played by Michael B. Jordan, whose performance can break your heart or fill it with joy, sometimes simultaneously.
