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

Forbes found 1,810 billionaires this year, down from last year's record of 1,826. The aggregate net worth of the billionaires was 6.48trillion dollars, 570billion dollars less than last year.

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.

Yes Man is a heartwarming blockbuster that explores what would happen if you answered "yes" to every question in your life. Jim Carrey's character takes on this challenge and ends up learning Korean, taking flying lessons, and getting promoted. He goes from being a pessimistic divorced man to an exciting trendsetter and finds a new girlfriend in the process. It might sound like fiction, but this movie is loosely based on a memoir of the same name by freelance radio producer Danny Wallace.

Back in the movie wasteland of last January, no one could have guessed what a bounty of good films the year would bring. Not just good films, but several that measure up to our idealized notions of what the medium once was. Two candidates for the top of the heap pretty much chose themselves. For sheer entertainment, the clear call is 'American Hustle,' David O. Russell's joyous celebration of 1970s-era con artists and their intricate cons. For innovation-a new theatrical experience born of new technology-'Gravity' whirls in its own orbit. With the understanding that there's nothing to be said against 'American Hustle,' and everything to recommend this screwball comedy for the ages, I think 'Gravity' is the best movie of the year.
