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

Graham Allison, the famous Harvard professor, also warned that east Asia was headed towards the “Thucydides Trap”, adding: “When a rapidly rising power rivals an established ruling power, trouble ensues.” In early 2013, the then prime minister of Luxembourg, Jean-Claude Juncker, warned that 2013 was looking dangerously like 1913. The Economist also warned at the end of 2013, “A century on, there are uncomfortable parallels with the era that led to the outbreak of the first world war.”
For example, taxi drivers who take a detour or refuse passengers can also be fined a maximum of 2,000 yuan.

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.

电池电力可能最终被证明是一种过渡性技术。最近电池成本的降低速度已经放慢了,特斯拉曾经承诺要在2017年生产出价格在35,000美元左右的Model 3。要实现这个目标,特斯拉的电池成本需要下降30%。相比之下,丰田(Toyota)最近的举动非常出人意料。它与特斯拉签订的电池供应协议即将期满,但丰田并未续约,而是准备加倍投入研发氢燃料电池。燃料电池的成本下降速度要快于普通电池。而且燃料电池的拥趸们认为,车主肯定会更喜欢充电速度相对更快的燃料电池,而不是要为充电等上好几个小时。
