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

相比之下,十年前名列榜单前20的城市中有6个亚洲城市、10个欧洲城市和4个美国城市。这项调查计算了93个国家的131个城市的生活成本,研究结果用于企业计算转移员工的成本。
调查显示,大多数女性在求职时正在或者已经因性别偏见受到影响,因为雇主不愿意提供产假。为了避免雇主因需要付产假津贴和提高就业竞争力可能带来的歧视,据报道,一些女性求职者选择在大学毕业前结婚生子。
此外,城镇人口也有所增加,现在已经占到总人口的55.88%,相比2010年普查时增加了6.2%。

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.

在实验中,参与者们被要求回忆一些他们在实验开始的时候看到的图片,其中,一半参与者在回忆之前进行了举重训练,另一半参与者没有进行这样的高强度活动。他们发现,参与了举重训练的人在记忆能力上有所提高。这项研究实现了运动研究上的独辟蹊径,其他研究的研究对象多是对有氧运动本身,研究时间跨度长达数,但是这项研究的研究对象却是人类记忆,在研究时也仅仅是要求参与者们花一点时间举重而已。研究人员证明了其实提升记忆力并不需要数个小时的锻炼。下次再有谁让你去举重或者去健身馆锻炼的话,你大概会想感谢他一番的吧?
What dangers does the Fed present to EMs today? One of the biggest risks, says Mr Koepke, is that it might “get behind the curve” and delay raising rates for too long. This would result not only in a surprisingly big hike when it came, but also a higher terminal interest rate than would otherwise be the case.
There were multiple instances of the glamourous royalty keeping Canadians waiting, including the arrival, where the family took a whole 20 minutes to disembark in order to be greeted by the Canadian welcome party.

But when he gave us his long-gestating free adaptation of Michel Faber’s novel Under the Skin, the result really was gasp-inducing: hilarious, disturbing, audacious. No less an A-lister than Scarlett Johansson plays an alien in human form who roams the streets and shopping malls of Glasgow. Perfectly genuine footage of real-life passersby is shown as the incognito Johansson impassively sizes up these earthlings for their calorific value. Then actors will step out of the crowd for their scenes with the great seducer. She takes them back to her place: a mysterious dark cavern in which, in an erotic trance, they submit to being imprisoned and farmed for their meat – and perhaps, who knows, for their very soul.
3. Elasticity of Demand.The cure for low prices is low prices. That cliché can be applied to both the supply and demand side of the equation. Will oil selling at fire sale prices spur renewed demand? In some countries where oil is more regulated, low prices may not trickle down to the retail level. Countries like Indonesia are scrapping subsidies, which will be a boon to state coffers but will diminish the benefits to consumers. However, in the U.S., gasoline prices are now below $2.40 per gallon, more than 35 percent down from mid-2014. That has led to an uptick in gasoline consumption. In the waning days of 2014, the U.S. consumed gasoline at the highest daily rate since 2007. Low prices could spark higher demand, which in turn could send oil prices back up.
Coca-Cola cut its sales forecast for this year as it struggles with a consumer slowdown in China, sending the drinks group’s shares down more than 3 per cent.

As for the fortunes of the gig economy, the UK will be a key country to watch. The government is due to respond to an independent review into whether British law is keeping up with this new trend.
