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

Tesla:In an effort to blunt criticism about slow refueling times for battery-powered cars, Tesla TSLA -1.54% starts to roll out of a network of battery-swap stations. CEO Elon Musk must hope he can outdo Shai Agassi’s Better Place, which tried to build a whole company around battery-swaps before going bankrupt in 2013.

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.

In addition, you can set up recurring reminders, which are perfect for remembering to mail estimated quarterly tax payments, renewing subscriptions, running payroll and other things you tend to forget.

About this series

Since 2001, I’ve helped direct an annual 创意家居抢占市场 市场看重实用性 recognizing top social entrepreneurs: those who develop effective, original approaches to dealing with social problems and who rely mainly on private funding and volunteers to see their ideas to fruition. They are leaders of America’s civil society, doing the things that government can’t do—or can’t do as well.

'Short Term 12' is one of those small indie features that stays with you in a big way. It's only 96 minutes long, a modest production set in a foster-care facility for troubled teens. Yet Destin Cretton's direction and Brie Larson's performance elevate the film to, well, one of the year's very best. Ms. Larson is almost a sure thing for not getting an Oscar-this year's competition is unusually fierce-but do catch up with her portrayal of Grace, a 20-something supervisor who is far from untroubled in her own life.

Another indicator of bitcoin’s momentum is the number of mainstream businesses that accept it. In 2014, Microsoft MSFT -0.84% , PayPal, Dell, and Dish Network DISH 2.24% , among many others, announced they would accept bitcoin as payment for a range of products. Those companies joined companies such as Target (which accepts Gyft, which can be purchased with bitcoin), Overstock.com, and WordPress. Even the publisher of Fortune, Time Inc. TIME -0.40% ,began accepting the cryptocurrency for magazine subscriptions. Yahoo YHOO -1.02% also added bitcoin to its Yahoo Finance tracking site last year, lending the currency additional legitimacy, and Google Finance GOOG -1.30% quickly followed suit. “Adoption of bitcoin is becoming more commonplace, and we feel it is relevant to our industry and to our users,” a Yahoo spokesperson told CoinDesk. Don’t be at all surprised if Yahoo soon goes even bigger on bitcoin—whether by acquiring a bitcoin startup or some other announcement—as part of CEO Marissa Mayer’s ongoing effort to make the stalling search giant more hip.
