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

Why does beauty exist? To answer this question, Richard O. Prum, an ornithologist, is working to revive an idea advanced by Charles Darwin: the attractiveness of an animal to another of its species isn’t only tied to fitness and good genes. Rather, animals — especially birds in Dr. Prum’s work — are making subjective decisions. He hopes that evolutionary biologists will stop “explaining away desire.”
北弗罗里达大学的一个有趣的实验证明光脚跑步比穿鞋跑步更能提高记忆力。和那些在实验室和室内坐在桌子边进行的试验不同,在这个实验中,研究人员们引入了一些有趣的观点来探索提高记忆力的奥秘。实验的研究对象为“工作记忆”,即人们加工信息和回顾生活细节的能力。科学家们发现,光脚跑步比起穿鞋跑步来说,可以对记忆力产生轻微的提高。在试验中,年龄为18-44周岁的参与者们被要求跑两轮,一次穿鞋,一次不穿鞋。

“它说明人们看重个人经验,胜过其他可用信息,”库迪斯表示。人们离一个重要事件的中心越远,此事对他们的风险胃口影响就越小。

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.

“I think the best way to engage young people in the process is to win,” he says.
