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

理查三世是金雀花王朝的最后一位国君,都铎王朝的继任者将其塑造成了不惜一切代价追求权力的无恶不作的暴君,还称他谋杀了他的两个侄子-也就是“塔中王子”-来保住王位。
单词inspection 联想记忆:
The Warriors are one of the best teams in NBA history, and you can put their championship run up against any team in NBA history for the best playoff performance ever. But there's also a legitimate question of what this means for the sport. If the best or second-best player of all time stands no chance against this team, what does it mean for the sport's competitiveness? It hasn't been a problem so far, thanks to an extremely wild offseason, but the question remains: what happens to a competitive sports league when it's not truly competitive at the highest level?
这是光明的季节,也是黑暗的季节……
More advanced components are in short supply, however, which could leave many customers waiting long after September to get hold of the new iPhone. That presents an opportunity for rivals such as Samsung’s new Note 8 or Essential, the smartphone maker led by Android co-founder Andy Rubin, which is targeting premium customers such as Apple’s with its slick $699 device. Google is also said to be preparing a new version of its Pixel smartphone, which has proved popular with early adopters.
我是否玩儿得太high了?缺乏实现某些事情的动机会让你失去平衡或者稍后会让你感到筋疲力尽,很有压力。休息一下是非常有必要的,但是如果你休息得过了头从而使生产力降低,或者你养成了太过拖拉的习惯,那么或许就需要时间来平衡你的时间安排,以便你可以完成大量的事情而仍有时间休息娱乐。

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.

Until now Thor has been the neglected child of the Marvel Cinematic Universe. Though some liked Kenneth Branagh’s first film featuring the god of thunder, Chris Hemsworth was arguably overshadowed by Tom Hiddleston’s preening popinjay of a villain, Loki. And the second film, the humourless Thor: The Dark World, is widely regarded as the worst film released by Marvel Studios to date. So to inject new life into this sagging franchise, Marvel brought in New Zealand comedy auteur Taiki Waititi to add some Kiwi quirk. This time Thor faces down the goddess of death, played by Cate Blanchett. Thor may have the hammer, but she has the attitude. Released November 1 in Serbia and Hungary, November 2 in Cambodia and Israel and November 3 in India and Canada. (Credit: Marvel Studios)

但是我们波士士顿波士顿咨询集团不认为中国本次改革会导致中国经济不稳定。我们相信中国经济在习主席的领导下会持续高速增长。我们相信上个星期的改革(三中全会)会确保中国经济从现在一直增长到(至少)2020年。根据我们已掌握的资料,我们预测中国经济在未来10年会增加4万亿美金(而书中说是6.4万亿。2012中国GDP为8.3万亿美金)。如果加上印度,亚洲两大国未来的增长总量会达到10万亿美金。在此期间,中产阶级会迅速膨胀,进而增强对经济增长的乐观态度。当然,没有人能完美地预测未来,在我们的近期的一本关于中国和印度经济发展的书中(《Trillion Prize:Captivating the Newly Affluent in China and India》),我们也描述了一些经济增长缓慢的例子。不过总体上我们还是对中国的未来保持乐观态度。

Participants in the study were between the ages of 18 and 44 and were asked to run twice – with and without shoes. After completing their quick runs, researchers found that the heart rate and overall run speed of each participant had no effect on memory, but the presence of shoes or bare feet did. The researchers have hypothesized that the need to engage the mind while running barefoot to avoid pebbles or other impediments could have a positive impact on a person's ability to remember things. If you're an adventurous person, you might try taking a barefoot jog around the block before your next test or before you need to remember something important.
