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

镜头切换到《爱乐之城》的演员和剧组人员那里,他们高兴得抱成一团了,但大家可以听到比蒂好像在说:“应该是爱玛?斯通。”而唐纳薇回应道:“什么?”当《爱乐之城》剧组上台领奖时,可以听到旁边的舞台管理人员说:“哦……哦!天啊!他拿错信封了!”
“很显然,单独一个年度,即使是创记录的年度,不可能告诉我们很多关于气候变化趋势的东西,”德国波茨坦气候影响研究所地球系统分析部门主管斯德范·拉姆斯朵夫(Stefan Rahmstorf)说。“然而,有记录以来的最热年度是2014年、2010年和2005年的这个事实清楚地表明,全球变暖并没有‘在1998年停止’,像一些人喜欢错误地宣称那样。”

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.

‘Episodes’ This comedy on Showtime, too often overlooked, follows the bewilderment of two British TV writers stuck in Hollywood creating a series for Matt LeBlanc, who plays a diva version of himself very convincingly. Not many shows set in the entertainment industry can sustain the conceit, but this is one that got even better in its third year.

Despite car and truck sales that motored past 16 million for the first time since 2007, recalls dominated the news for most of the year. General Motors GM 1.42% held center stage, dealing with cascading revelations about faulty ignition switches and recalling millions of vehicles.

For starters, breaches like that of Bitstamp and the much larger (valued at about $400 million at the time) 2011 hack of the exchange Mt. Gox are often misconstrued as security issues with the currency itself. But they are only signs of flaws in those particular exchanges and not a sign of an issue with the underlying technology. And it is the underlying technology behind bitcoin that most excites. As we wrote in the “Shape the Future” package of our January 2015 issue, most of the vocal enthusiasts so bullish on bitcoin—from big-name entrepreneurs like Marc Andreessen to the developers and miners who spend their days refreshing the bitcoin Reddit page—are more interested in the applications that can be built on bitcoin’s “block chain,” the currency’s foundational backbone, than they are in bitcoin as a monetary system. The block chain allows the secure exchange of any form of value between two entities.
