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

SETTING: This house is in Kenwood, a neighborhood of 19th- and 20th-century Tudors, Mediterraneans, Victorians and colonial-style houses between Cedar Lake and Lake of the Isles, in the city’s Chain of Lakes. Roads are curving; sidewalks are lined with maple and ash trees. According to the listing agent, many of the neighborhood’s older houses have been restored, while houses built within the last 30 years have been torn down and replaced.

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.

Late last year, the World Health Organization declared that Zika virus was no longer a global emergency. But the disease’s effects on babies who may live for decades are only beginning to be understood. In northeastern Brazil, where links between the virus and birth defects like microcephaly were first detected, families struggle to give the best lives possible to stricken babies. Researchers hope to find clues about the virus’s effects on the fetus by studying pairs of twins in Brazil in which one was born with birth defects and the other was not.
