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

由于新出口订单增幅与上月基本持平,新订单总量增长趋缓。但就业流失加速,投入品价格增幅收窄,企业对客户收取的价格略有回升。

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.

No. Having ended Robert Mugabe’s 37-year rule — with a little help from the army — Emmerson Mnangagwa has promised free elections in 2018. That raises one problem: he could lose. He must at least pretend elections are fair because he needs donor money to help turn the economy around. That would mean electoral reforms, which risk a loss for his unpopular Zanu-PF. Even if Mr Mnangagwa were prepared to roll the electoral dice, it is not clear the army is. Having got their man in, Zimbabwe’s generals are unlikely to allow the public to kick him out.

Stock pickers encountered difficulty this year in part because of concentration at the top of the market. Just five stocks—Apple, Berkshire Hathaway, Johnson & Johnson, Microsoft, and Intel— accounted for 20% of the market’s gains. If you weren’t at least equally weighted toward them, you had virtually no shot at making up for missing their enormous, index-driving gains. A majority of the market’s stocks did not perform nearly as well. According to the Leuthold Group, only 30% of S&P 1500 stocks posted gains exceeding the index itself. You’d have to go back to 1999 to see anything like this.
