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

On the sales front, General Motors and Ford F -0.13% lost market share to Chrysler, which leveraged its Jeep brand to previously unimagined heights – and then, metaphorically left its heritage behind when it established legal domicile in the Netherlands and changed its name to FCA US LLC.
However Mr Kwon warned that young people should be cautious when seeking such operations.
The Asia-Pacific region was the main driver of international growth at movie houses, up 13%, and China accounted for nearly half of the entire Asia-Pacific total.
在主要贸易伙伴中,以美元计的出口确实出现增长的包括对美国的出口,同比增长5.5%,达到370.6亿美元。而对韩国的出口也显示增长8.3%至102亿美元。
n. 框,结构,骨架
So too would be concluding the EU’s own (re)negotiation of its existing trade agreement with Mexico. And there is a good chance Brussels could beat Donald Trump to the finish line on a deal with Mexico.

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.

And regarding Ukraine, the Russian president again denied that there are Russian troops operating inside eastern Ukraine where a pro-Russian separatist movement is fighting Ukrainian government troops.

Two weeks later, Mr. Bernheimer was among the dozens of long-established old master dealers attending the London evening sales. In the past, they would buy at these auctions to stock up for the Maastricht European Fine Art Fair in March in the Netherlands. But with sellers encouraging Sotheby’s and Christie’s to compete for their business with ever-higher valuations, and auctions now marketed to a shallow pool of wealthy buyers, there was conspicuously little trade bidding.
