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

外部事件的影响。《消费者报告》(Consumer Reports)杂志曾经对Model S大加吹捧,但最近该杂志也报道了它的一些常见故障,包括门把手失效,中控触屏白屏,导致车内大部分功能不能使用等等。汽车网站Edmunds.com也找了Model S的麻烦。更多此类报告无疑会影响特斯拉到目前为止非常正面的声誉。
Brazil lost that 1950 final, 2-1, to Uruguay, a historic humiliation that still stings Brazilian fans today. Belmonte, 85, hopes he'll get to see his country regain its honor. "I hope Brazil will be able to win this time," he said. "This is our revenge. I want to go see our revenge."

perspective

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.

Some people remain attached to a theory that can be described as resource scarcity. At its heart this theory suggests that resource development follows a linear pattern in which low-cost resources are developed first, meaning that most if not all future development must be more costly. Unfortunately the history of the industry does not support this view. If anything the experience of the past few decades suggests that the opposite is true.
