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

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 2005, Davidson found herself constantly picking up sippy cups her one-year-old son Jake would toss to the ground. She went to Target, bought a sewing machine, and created the SippiGrip, a leash-like contraption for a sippy cup. Her entrepreneurial dreams were slowed, however -- she was recruited by Microsoft to join the HR team working with its X-Box Group. But in 2007, she launched the SippiGrip at a national trade show. Fortuitously, Target approached her to join its 2008 Parent Invented Products Program and today, Davidson's BooginHead line is sold by retailers like Walmart, Babies "R" Us, and Amazon.com.

Yes. Mr Meade is the candidate of the ruling Institutional Revolutionary Party, or PRI. His main rival is the hard leftist Andrés Manuel López Obrador, a passionate orator who can work a crowd. Mr Meade has a lot to overcome: he will have to convince voters that they can trust him, after he put up petrol prices by 20 per cent overnight in January, triggering a surge in inflation. He will also have to reveal himself as his own man, not just a clone of an unpopular government that has failed spectacularly to rein in rampant corruption and crime. But backed by the formidable PRI get-out-the-vote machine, he could prove unstoppable. In Mexico’s one-round-only system, 30 per cent of the vote might be enough.

From the beginning, social networks have been effectively walled off from the Internet. The treasure trove of content on Facebook, for instance, doesn't generally show up on Google (GOOG). But does it have to be that way? Wouldn't it be convenient to see Twitter search results automatically displayed alongside a standard Google search, for example? And why, for instance, don't the latest tweets about a restaurant pop up when you're searching Yelp (YELP)? The competing interests of different networks sends this content behind proprietary walls, but a number of tools offer creative ways to bridge the gulf. (Full disclosure: My company has developed one such tool.)
