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

Less than an hour ago the official manufacturing PMI for November came in at 49.6, the fourth consecutive month of contraction and below the 49.8 reading economists were looking for. Analysts at ANZ said, in relation to that PMI series:“With soft growth momentum and deflation pressures creeping up, we expect the authorities to further ease monetary policy and continue to implement an expansionary fiscal policy in order to prevent further slowdown of the economy in 2016.”

In truth, slower growth of about 8 per cent could be better for China and for the world. More environmentally sustainable and equitable outcomes would ease popular concerns and higher consumption would ease tensions over global trade.
Hillary stays on: Clinton’s CV is chock full of firsts: The only first lady to become a U.S. senator turned viable presidential candidate turned secretary of state. Now a private citizen, she continues to be one of the most watched and listened-to women on the planet. All bets on that she will be the 2016 Democratic presidential candidate and the free world’s presumptive next leader. She’s done little to quiet the chatter, including hitting the speaking circuit last month at an estimated $200,000 fee per event and inking a reported $14 million book deal.
达洛伊西奥设计了一款名叫Summly的应用软件,该软件能够将繁冗的文章精简成几行关键句子。早一代Summly软件发布后,技术观察家意识到在这个无论资讯还是财报,一切新闻都快速阅于掌上的时代,这样一款简洁、精准的摘要软件蕴含着巨大的价值。该应用吸引了包括好莱坞明星和亚洲首富李嘉诚在内的全世界投资者的兴趣。

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.

So the chances that the UK will have the slowest-growing economy in the G7 next year should be around one in four.
