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

8.Form or Join a Study Group
n. 紧张,拉紧,血统
They must understand in their bones that it is illegitimate to make temporary power permanent by rigging elections, suppressing contrary opinions or harassing the opposition.

欧洲工商管理学院(Insead)领衔2017年英国《金融时报》全球MBA百强榜。这是这所拥有多个校区的国际商学院连续第二年高居榜首,去年该学院首次摘得桂冠。
In an effort to protect China's role in the global economy as a manufacturing hub, the central bank devalued the currency in August, in the biggest drop in decades. Later in the year, after the International Monetary Fund added the renminbi to its group of global reserve currencies, the value of the currency fell further, possibly reflecting capital outflows.

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.

For over two decades I have been writing about the rise of Asia and the dynamic driving it. There is an extraordinary consensus among east Asian leaders that Asia needs to use this window of opportunity to focus on economic development and growth. War is the biggest obstacle to development. If Asians were truly stupid, they would engage in such wars and derail their enormous development promise. Most Asian leaders, barring North Korea, understand well the dangers of war. Hence, while there will be tensions and rivalries in the region, there will be no wars in the region, in 2014 or in 2015. As 2015 unfolds, I would like to encourage all western pundits to understand the underlying Asian dynamic on its own terms, and not on the basis of western preconceptions.

It even featured in the March 19, 1870, issue of Scientific American magazine. Made by Thomas Luders from Olney, Illinois, and called a "pedespeed," the wheels then were much smaller, measuring around 36 centimeters (15 in) in diameter. Luders also said the skates could be used by anybody, irrespective of their physique. He himself was a large, heavy man, and he claimed he could use them for two straight hours without getting tired. Another version of wheel skates, appearing in 1923, had its tires on the inside of the foot rather than outside. (Other than the size of the wheels, the main improvement made by Chariot Skates is the small tire at the back of the bigger tire for increased stability.)

万分沮丧之下,他发明了可以允许自拍的东西:他称之为"伸缩杆"。因为智能手机还没发明出来,所以,连接在自拍杆末端的是一个微型相机。在杆的前端有一面小镜子,方便使用者调整他们在相机里的姿态。他在1983年为"伸缩杆"申请了专利。虽然自拍杆进行了大量生产出售,却属商业败笔——相片的质量比较差。另外,以前的研究表明,那时的女士会因自己有自拍的想法而感到尴尬。在2000年,自拍杆被韦恩·弗洛姆(Wayne Fromm)重新发明,那时,上田宏的"伸缩杆"专利期尚有三年。弗洛姆称他的自拍杆为"快捷豆荚"。他认为他才是当今自拍杆的发明者,甚至起诉其他自拍杆生产者。当被问到上田宏的自拍杆时,弗洛姆评论说它们是"先前的艺术"。
