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

It scares/intimidates people and they don't know better anyway.

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.

The lyrics are stupid, but who cares? Tom Jones sings like nobody's business, and pounds the theme to Thunderball out with a silky energy. It's powerful but alluring.

Tom Jones and James Bond probably go out for dry martinis together all the time. They're the perfect pair.

But if the U.S. can avert that Washington-made crisis, the outlook for workers finding jobs is actually looking pretty good for next year. For one thing, the damage of superstorm Sandy will have to be repaired, meaning jobs in construction and retail. Businesses, meanwhile, which have held off investing and hiring because of uncertainty over the fiscal outlook, might finally open their wallets. That means more jobs, too.[qh]

Some say job growth could accelerate from its slow pace. 'I think businesses are going to have to hire,' said Bob Baur, an economist with Principal Global Investors.[qh]

China’s reserves have fallen for nine of 11 months this year and stand at $3.43tn, as investors sell renminbi assets to protect themselves against depreciation and the central bank sells dollars from its reserves to curb renminbi weakness. Falling interest rates in China and expectations of an imminent rate rise by the US Federal Reserve have also fuelled outflows. Reserves rebounded mildly in October, suggesting outflows had diminished.
