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

《小镇疑云》,BBC America,3月4日播出。大卫·田纳特(David Tennant)携第二季归来,在这部引人共鸣的英国推理剧中继续饰演亚力克·哈迪(Alec Hardy)探员(去年他在美国翻拍版的《小镇疑云》[Gracepoint]中饰演埃米特·卡弗探员)。这部剧将于周一在英国首映,制作人们已经开始谈起第二季的秘密情节了,编剧克里斯·齐布纳尔(Chris Chibnall)在接受英国杂志采访时说的话可能会让剧迷不爱听,“第二季不是讲罪案的。”奥莉薇娅·科尔曼(Olivia Colman)继续饰演艾丽·米勒(Ellie Miller)探员,夏洛特·兰普林(Charlotte Rampling)和玛丽安娜·琼-巴普迪斯特(Marianne Jean-Baptiste)也加入了演员阵容。

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.

?Women fall for him because he's exciting to be around and this plays a much larger part in a relationship than most think. It's the key to a great first date.

This is probably true -- and only serves to make him that much more attractive to the ladies.
