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

The consumer price index rose by 1.8 per cent year-on-year in January, from 1.6 per cent in December 2015. However, CPI continues to trail Beijing’s target of “around 3 per cent“.

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.

But the crash hit. The economy tanked. The recession lasted 30 months. Wall Street lost over $8 trillion of our retirement money. In the first decade of the 21st century, from the 2000 dot-com crash till 2010 disaster Wall Street's had a negative inflation-adjusted performance. Today Wall Street's returns are just barely beating inflation. No wonder investors feel cheated by Wall Street's casinos.

还有哪对系列电影的荧幕情侣可以像《暮光之城》的克里斯汀?斯图尔特和罗伯特?帕丁森这样成功开创戏路呢?两个人都成为了影坛名角。帕丁森在最新作品《好时光》中延续了他近年来这种让人几乎认不出的造型风格。在《迷失Z城》中,他把自己打扮成胡子蓬乱的眼镜男,如今他又把头发染成亚麻色,变身为一个试图在纽约完美做案,结果却让患有发育性残疾的弟弟(本?萨弗迪饰)被捕的银行抢劫犯。他试图用盗取的钱来给弟弟交保释金,结果麻烦接踵而至。很多的麻烦。除了饰演弟弟一角外,本?萨弗迪还和自己的哥哥约书亚?萨弗迪共同执导了这部电影。《好时光》入围了今年戛纳电影节的主竞赛单元,参与角逐金棕榈奖。该片于11月3日在日本上映,11月17日在英国和爱尔兰上映,11月23日在希腊上映。(资料来源:A24制片公司)

'Inside Llewyn Davis' finds the Coen brothers, Joel and Ethan, in a hauntingly somber mood that somehow translates into memorable drama. I think my review should have made it clearer that this elegy for a casualty of pop culture is a special taste; some of it is fairly glum. So much of it, though, gets to something stirring by way of Oscar Isaac's phenomenal performance as a self-defeating folk singer fatefully dedicated to his art.

The “cool” factor isn’t the only issue. Security and privacy, particularly around the management of consumer data, remain a concern as the tech industry seeks to bring more of our body parts online. As The Economist notes, the glamour of developing sensors and algorithms for wearables is distracting everyone from glaring missing elements, “standards, interoperability, integration and data management” and “intellectual-property rights and regulatory compliance” among them. All this in an environment where paranoia remains over the National Security Administration’s activities.
