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

Since the establishment of Avic 1 and Avic 2 in 1999, which really marked the beginning of China’s push into the commercial aerospace market, there has been no doubt about China’s intent and the direction it wants its industry to take. But the pace at which it would achieve this ambition was less uncertain. Almost 20 years on, things have become much more clear, and there is now little doubt that China is well on its way to succeeding where several other countries have failed in becoming a full-fledged player in the large commercial aircraft manufacturing sector, with the potential to disrupt the long-standing duopoly of Airbus and Boeing.

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.

"We are quite interested in looking at China's efforts and experience in combating corruption. It's a problem we are faced with in South Africa, and one we are tackling with a lot of vigor.Recently, the South African government introduced new measures to combat corruption. This is interesting, because it was immediately after a visit by our minister for public services, who met with the minister here who is responsible for anti-corruption measures.So this is one of the examples of the usefulness of this interaction between our leadership and the leadership of the People's Republic of China."
