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

That figure is more than two times the city's population of about 10 million.
'For what is really exceptional, not seen on the market, there are really clients looking for such investments,'
Two days ago here in Brazil, we were shocked when we spent some time with some children living on the streets. And this is what one child told us: "I wish I was rich and if I were, I would give all the street children food, clothes, medicine, shelter and love and affection." 在巴西,我被2天前见到的情景震惊了,那时我和当地的小孩在玩耍,其中一个小孩说:“我希望我能富裕起来,然后我会给这个街道所有的小孩饭吃,给他们衣服穿,医疗,住房和爱”。
但这种理念不会让英国退欧或者让特朗普当选总统。
The fact is that I really don't careabout the popularity and also really focus on my work. Every time I alwaysfocus on how best to proceed with the next scene. My focus is on the action andstory, never the popularity.

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.

Less than an hour ago the official manufacturing PMI for November came in at 49.6, the fourth consecutive month of contraction and below the 49.8 reading economists were looking for. Analysts at ANZ said, in relation to that PMI series:“With soft growth momentum and deflation pressures creeping up, we expect the authorities to further ease monetary policy and continue to implement an expansionary fiscal policy in order to prevent further slowdown of the economy in 2016.”
However, the state is also wary of the fast growth in online finance, which is largely unregulated and the risks of systemic crises may be high. Since 2007, 370 P2P lending platforms have failed in China, of which 270 failed in the past year, according to research by Morgan Stanley and Wangdaizhijia, a Chinese research group.

这意味着投资者正为特斯拉的未来前景投下重注,出价要远远高于对其他豪车厂商实际表现的评估。梅塞德斯-奔驰(Mercedes-Benz)的制造商戴姆勒(Daimler)去年售出了超过250万辆车,市值约为850亿美元。所以,尽管戴姆勒的销量是特斯拉的70多倍,但它的市值还不到特斯拉的3倍。

Today's and tomorrow's technology sits on top of multiple layers, every one of which is changing and has to inter-operate with others. This makes our gadgets, the internet of things, phones and laptops unstable. And it makes consumers irritated. How many of your apps actually work--and actually make life easier, faster or more fun? I'd expect to see consumer cynicism grow, as delight is overtaken by disappointment. This will put pressure on hardware and software developers to deliver that most boring of qualities: reliability.

得克萨斯州成为首批摆脱经济衰退的州之一,该州凭借低税收负担、监管环境可预见性和熟练劳动力不断吸引企业投资。根据穆迪分析公司的统计,得克萨斯州的就业人数到2017年将以每年3%的速度增长。(亚利桑那州的预计就业增长速度仅高出0.04%)。得克萨斯州吸引了众多加利福尼亚州企业的关注,得州州长里克?佩里(Rick Perry)毫不顾忌地把两个州的商业环境相对比。最近几年来,加州企业电子港湾(EBay)和电子艺界(Electronic Arts)都选择在得克萨斯州大举扩张。奥斯汀一直是商业活动的温床,今年埃森哲咨询公司(Accenture)、AT&T公司、国家仪器公司(National Instruments)和时代华纳有线(Time Warner Cable)都宣布计划在该地区大幅增加就业岗位。
