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

1)谢谢:只是一般的礼貌?没错。那你告诉我,上一次你忘了说(或者拒绝说)谢谢是在什么时候?无论是在公开场合还是在私底下,说一句真诚的“谢谢”都会为你树立好口碑。也别忘了妈妈给你的忠告,“说请”。人们都喜欢比人请自己去做事而不是接受别人的命令去干活。

But once again, Bryant said he's fine, that his health is fine, that his shot is fine, and he diverted the conversation elsewhere, largely to his teammates and the team's overall scheme.

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.

In my country, we make so much waste, we buy and throw away, buy and throw away, and yet northern countries will not share with the needy. Even when we have more than enough, we are afraid to lose some of our wealth, afraid to share. 在我的祖国,我们制造了如此之多的垃圾,我们购买商品,我们随之丢弃,买来,再丢弃。然而有些国家,有些人,却不会分享给那些真正需要的人们,甚至他们拥有的远远超过自身需要的时候。他们害怕分享,害怕失去自己的财富。

'12 Years A Slave' is shattering and anguishing, a singular anomaly in an entertainment medium.
