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 January-to-November period in the United States this year was the warmest first 11 months of any year on record for the contiguous states. And 2012 will likely surpass 1998 as the warmest year on record for the nation, according to the National Oceanic and Atmospheric Administration.

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.

A study published in the journal "Clinical Psychological Science" in 2012 showcased the power of self-imagination, which showed the technique could help people with impaired memories, as well as individuals with no memory problems. As with other studies of human memory, the scientists asked participants to remember a list of words related to certain personality traits. The participants were then asked to use a specific strategy to help them recall the words. For example, some participants were asked to remember one personality trait by thinking of a second word that rhymed with the trait. Other participants were asked to remember the definition of the trait while others were asked to engage in "self-referential processing" where they would think about the trait in a personal, self-reflective way.

Banks just cannot afford to keep up. At Goldman Sachs, for example, net revenues have dropped about a third since 2009, beaten down by structural shifts in trading and new rules crimping risk-taking. The bank tries to keep its pay ratio stable, so that means smaller total packages for the typical employee.

Among the gargantuan hedge funds that make up a majority of the industry’s assets under management, dispersion of returns shot up to notable levels. And for every big winner, like William Ackman’s Pershing Square, there was a big loser to counterbalance it, like John Paulson’s Advantage Fund. Investors choose hedge funds for their “non-correlated returns,” meaning a tendency to move opposite from the general market’s direction. They certainly got such returns this year, unfortunately.
