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

Brands with the most incentive to coast in 2015:Jeep, which must be exhausted after lifting sales an astonishing 44% on the back of the new Cherokee, and Subaru, now the 10th most popular brand in America after improving its sales by 21% in its usual fashion: quietly.

“It’s horrible,” he said. “Whenever I see someone with a gun, I take it away and report it to police.”

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.

哈佛大学著名教授格雷厄姆?阿利森(Graham Allison)也警告说,东亚已走向“修昔底德陷阱”(Thucydides’s trap),他并补充道:“当一个迅速崛起的大国与一个老牌霸权国竞争时,麻烦接踵而来。”2013年初,时任卢森堡首相的让-克洛德?容克(Jean-Claude Juncker)警告称,2013年看起来像1913年一样危险。2013年底,《经济学人》杂志(The Economist)也警告说,“一个世纪已过去,当今世界却与那个导致第一次世界大战爆发的时代有不少相似之处,令人不安。”

Yes. Mr Meade is the candidate of the ruling Institutional Revolutionary Party, or PRI. His main rival is the hard leftist Andrés Manuel López Obrador, a passionate orator who can work a crowd. Mr Meade has a lot to overcome: he will have to convince voters that they can trust him, after he put up petrol prices by 20 per cent overnight in January, triggering a surge in inflation. He will also have to reveal himself as his own man, not just a clone of an unpopular government that has failed spectacularly to rein in rampant corruption and crime. But backed by the formidable PRI get-out-the-vote machine, he could prove unstoppable. In Mexico’s one-round-only system, 30 per cent of the vote might be enough.
