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

When M·A·S·H first aired, the characters of Hawkeye and Trapper were meant to be equally sized roles. It was with that understanding that Wayne Rogers agreed to take the role of Trapper John. However, as Alan Alda began to make changes to the characters and have more influence on the direction of the show, Hawkeye began to seriously eclipse Trapper.

葡萄牙的成就说明这种转变是可行的,它为各国政府和能源公司提供了一个实实在在的范例,也告诉他们为什么现在应该投资太阳能、风能、波浪能和其他可再生技术。

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.

新上榜学校中排名最高的是巴黎第九大学(Université Paris-Dauphine),排在第57位。
The mega-retailer didn't have a whole lot to complain about in fiscal 2010. Profits were up and, thanks to its sales, the company once again climbed to the top of the Fortune 500. Same-store sales were about flat for the year, but compared with Target's 2.5% decline, flat is good. Most remarkable was Wal-Mart's image overhaul. It helped that former CEO Lee Scott beefed up health care coverage for employees, thought more about the environment and became a public presence. Certain critics will never be placated and fiscal first-quarter results weren't the greatest. But there's no denying Scott left new CEO Mike Duke a company in fighting form.

关于“白”的定义总是存在一定程度的不稳定性。美国的爱尔兰与意大利移民,英国的犹太人,都曾一度被排除在白人多数群体之外,如今却因为他们的种族特征,同样被视为白人主流的一部分。与此同时,尽管犹太人也是白皮肤,特朗普的某些支持者们还是会把他们视为外来者,这些人经常在社交网络上散布反犹太的网络米姆。

你肯定知道,那个似乎永远都待在公司的老家伙现在依然不会使用电子邮件。到了2014年,如果你跟不上社交媒体的新潮流,你就跟那个老家伙没什么两样。今年发布于招聘信息搜索引擎Indeed.com的招聘广告,提及社交媒体使用技能的是去年的13倍。Indeed公司传讯总监艾米?克劳今年初接受数字经济新闻网Quartz采访时说:“从人力资源到产品开发,再到客户服务,企业各个部门对精通社交媒体的求职者的需求正在急剧增加。”预计将出现在Twitter和Facebook上的不仅仅是市场、销售和客服等部门,研发、物流和人力资源等差异巨大的团队也越来越多地使用Yammer等内部网络以简化操作流程。事实上,社交媒体已经发展为职场技能的重要一环,就连各大高校现在也纷纷面向不善社交的企业开设认证项目,帮助它们适应日新月异的社交媒体世界。

BETTER CALL SAUL (AMC, Feb. 8) Vince Gilligan and Peter Gould’s “Breaking Bad” spinoff is probably the most anticipated new series of the winter. Starring Bob Odenkirk as the crooked lawyer Saul Goodman, the show is set before the action of “Breaking Bad,” so any appearances by Bryan Cranston or Aaron Paul would be cameos at best. But the audience favorite Jonathan Banks reprises his role as the phlegmatic enforcer Mike Ehrmantraut.
The issue has also hit Beijing’s efforts to secure market economy status in the WTO, which it claims it will be entitled to automatically on December’s 15th anniversary of it joining. If China obtains that status it could affect the ability of the US and others to bring anti-dumping cases, as it would remove their ability to use prices in third countries for comparison.

Developer activity is also at a fever pitch. According to the contributor graph at GitHub, the total number of contributions to bitcoin’s master code in November was the highest it had been since spring 2012. Bitcoin is also the 31st “most forked repository” on GitHub—”forks” are basically proposed or in-progress alterations to core code—out of more than 900,000. In other words, for developers, bitcoin is trending. The number of open jobs currently posted at bitcoin companies also underscores developer interest: it’s at 105, which is close to the all-time high in September of 137, according to Bitcoin Pulse, which monitors such trends.

Little wonder, then, that Christie’s, the dominant player in the auction market for modern and contemporary art, is re-marketing its old master paintings as “classic art.” It will be offering old masters and other historical pieces next year at its Rockefeller Center sales in April, rather than January.

哈佛大学的一项研究证明,随着年龄增长,饮食可能会对你的记忆力有重要的影响。妇女医院的科学家们在《神经病学记事》发表的研究报告指出,食用含有大量饱和脂肪酸的食物(如红肉和黄油)的女性比正常饮食的女性记性更差。虽然研究人员暂时没有发现记忆力和饱和脂肪之间的确切联系,但是他们猜测饱和脂肪酸也许对基因有那么些影响。
Do you routinely roll your eyes? Do you have a weak handshake? Do you avoid making eye contact? These could all be career killers. People must understand that actions speak louder than words. And the majority of our communication is done through non-verbal cues. People could perceive some of your non-verbal communication habits as rude or unprofessional—and these things could eventually have a significant impact on the advancement of your career.

“Selling out!” “Pandering to the Americans!” The cries went up immediately when the official selection was announced. The list of directors crossing over to make films in English was a long one including the Italians Matteo Garrone and Paolo Sorrentino, Yorgos Lanthimos of Greece, Norway's Joachim Trier and even Guillaume Nicloux of France, a country whose cultural establishment is highly sensitive to the creeping Anglophone menace. The argument goes that Cannes is supposed to be a haven for world cinema; for English, there is Hollywood. But does it really matter? Films at Cannes in languages other than French or English play with subtitles in both languages – and that's a lot of text to deal with.
