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

We will deepen institutional reform to build a sound ecological environment.

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.

因此,有如此强大的南美洲队伍坐镇,主要的挑战力量将来自何方呢?嗯,来自欧洲的强势力量恐怕便是最显而易见的答案了,你还能去哪里寻找一个比西班牙更有冠军相的球队呢?作为一支卫冕冠军,并坐拥两届欧锦赛的冠军头号,这是一支不仅知道如何出色发挥,同时知晓如何赢得比赛的队伍。因此,虽然梅西和罗纳尔多曾获得所有年度最佳球员的头衔,但是哈维(Xavi)和伊涅斯塔(Iniesta)却将所有主要冠军据为己有。那么,他们在2014年将延续冠军生涯么?对于这个困扰世界上其他国家的问题,答案是肯定的。不仅大多数老将依然坚守岗位,许多包括科克(Koke )和蒂亚戈·阿尔坎塔拉(Thiago Alcantara)等有才华的年轻球员也加入了。不仅仅如此,他们还从东道主的眼皮下挖走了一个才华横溢的射手蒂亚戈·科斯塔(Diego Costa)收入囊中,因为这位马德里竞技(Atletico Madrid)的前锋选择为西班牙效力,而非自己出生国家踢球。

You'd probably never think that a belt could be integrated with artificial intelligence, yet Belty managed to do it and make it seem stylish. The Beltyautomatically makes you think, "why do I need this?" Then your second thought will probably be, "what if it's hacked and they make it so tight I can't breathe?" The first question is rational; the second one is far-fetched — but if it makes you think twice about buying this product, that's not a bad thing.
Domestically, an increasingly active middle class is generating pressure for more accountable governance. Mounting inequalities have nurtured a sense of injustice; 200m migrant workers remain second-class citizens and corruption is worsening. Tackling these problems is urgent, but China's economic successes have fostered an unwarranted self-confidence. Instead, motivated by the Arab spring, the system has moved aggressively to contain any social discontent that might spark more politically sensitive movements.

"We are quite interested in looking at China's efforts and experience in combating corruption.

There are no such circuit breakers in Hong Kong where the H-share index of mainland equities fell less than 4 per cent on unremarkable volumes. One might have expected more of a bloodletting.

Foreign H-share investors too might be presumed sellers, having been the most bearish on China’s economy. Yet yesterday, even as Shanghai opened down a further 3 per cent (before rebounding), Hong Kong’s H shares remained resilient.
