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

Sinta Nuriyah carries forth her family’s campaign in Indonesia, holding interfaith events and establishing a network of progressive Islamic boarding schools for girls.
On 2 March, the North's state-run website Uriminzokkiri warned that Pyongyang would respond to any balloon launches with "not just a few shots of gunfire but cannons or missiles".
So, yeah, I think they should tank and they might even be able to get some good value for Ibaka in a trade even if it would be a really quick about-face. God they're weird.

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.

A lot of the best James Bond theme songs sound like they belong in a lounge act. That's not a complaint, just an observation. For whatever reason, the English new wave act Duran Duran was given free reign to provide A View to a Kill with a new and exciting sound all its own. "A View to a Kill" was a hit song, and it probably would have been a success even without the James Bond connection. It's entertaining and cool and energetic, and it promises one hell of a good time. (Whether or not the movie actually lives up to that promise is a matter of some debate.)

会。2018年,美国总统特朗普将通过对中国采取惩罚性行动,来兑现他在竞选时许下的部分保护主义诺言。最可能的触发因素将是特朗普政府委托的、对中国涉嫌窃取知识产权的官方调查报告,以及中国补贴钢铁和铝生产的行为。在其贸易团队的敦促下,特朗普可能会下令采取报复性措施,其中包括征收惩罚性关税。此举是否会标志着贸易战打响第一枪,将取决于中国如何反应。如果中国决定征收报复性关税,或者把美国告上世贸组织(WTO),将标志着敌对状态的开始。
