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

“We weren’t looking to throw the bums out, as they might say about an election. We were just really impressed with a flood of new powertrains, ” says Drew Winter, WardsAuto World Editor-in-Chief. “What was great yesterday might be less impressive tomorrow because engine technology is changing so rapidly.”

在出售给Facebook前,WhatsApp一直特别反对植入广告。该公司首席执行官让o库姆在自己桌上一直贴着联合创始人布莱恩o阿克顿留下的一张便条,随时提醒自己牢记公司的核心价值观:“不要广告!不要游戏!不要宣传噱头!”这样一来,短信应用只好想出别的创意。比如Tango就在用户的短信“收件箱”里插入广告。中国互联网巨头腾讯公司旗下的短信应用——微信,则通过游戏、贴纸(类似于表情符号)和移动购物等方式谋取赚钱之道。Kik则提供一种被一些人称为“聊天广告”的功能,用户通过它能和幽默网站Funny or Die及电影信息网站Moviefone这类品牌运营的聊天程序进行交谈。

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.
