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

《癌症:众病之王》(Cancer: The Emperor of All Maladies),PBS,3月30日播出。该剧由《斯科茨伯勒:美国的悲剧》(Scottsboro: An American Tragedy)与《美莱》(My Lai)的导演巴拉克·古德曼(Barak Goodman)执导,肯·伯恩斯(Ken Burns)担任执行制作人,这部六小时的剧集是根据普利策获奖书籍、悉达多·穆克吉(Siddhartha Mukherjee)医生的《众病之王:癌症传》(The Emperor of All Maladies: A Biography of Cancer)改编的。

1999年中国航空工业第一、第二集团公司(之后两者合并为中国航空工业集团公司)的成立标志着中国开始进军商业航天领域,显示了中国迈向这一行业的绝心与意志。但实现这一雄心的脚步并不那么平坦。20年之后毫无疑问中国已经成为了大型商用航天领域的成熟玩家,将其他几国远远甩在身后,并有望打破空客和波音的长期垄断。

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.

To be sure, that excitement can certainly lead to unrealistic declarations from those in the community.
