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

仅过去6个月,这家诞生于澳大利亚的公司不断从亚马逊(Amazon)、贝宝(PayPal)、谷歌(Google)和Twitter挖角,其高管团队的实力由此大大增强。同时,它还与行业领导者Magento公司签署了一项备受关注的协议,后者承诺将为该公司引入数以千计的新客户。它最近撤销了旧金山新办公室的租约,由于人员扩张非常快,如今公司需要的办公空间已是当初预期的3倍。
Next year, crude from Libya--which experienced major problems exporting its oil in 2013 because of internal disputes--could flow again. Iraqi output also is set to increase. Even Iran, shut out of global markets for years, could return if an agreement is reached to relax sanctions aimed at curbing its nuclear development. All this could add as much as two million to three million barrels a day of Middle East output.

Batman vs Superman: Dawn of Justice is scheduled to hit theatres on March 23, 2016.

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.
