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

《生活大爆炸》中绝不缺少天才。不只是因为这部剧向观众展示了很多绝顶聪明的科学家,同时,演员玛伊姆·比亚利克还拥有神经学博士学位。因此,演员们想要在剧中展示他们的聪明才智,并将整部剧做到精益求精,这也不足为奇。剧中谢尔顿和莱纳德的公寓里有一块很大的白板,这对铁哥们几乎在处理任何事时都会用到它,从完成从学校带回来的工作,到决定是否等到看完最新一部《蜘蛛侠》再吃饭,都离不开这块白板。

遗憾的是,随着乌拉圭在当地时间周六(6月28日)被哥伦比亚淘汰出局,本届世界杯决赛将不再是巴西和乌拉圭之间的再次对话。如果巴西杀入7月13日的决赛,对手将可能是墨西哥、荷兰、哥斯达黎加、希腊、美国、比利时、阿根廷和瑞士中的一支(译注:1/8决赛中,墨西哥与希腊分别不敌荷兰与哥斯达黎加,憾别世界杯)。

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.

尽管你会忙个不停,但是不要忘记赞美生活中不完美的地方。我在徒步攀登喜马拉雅山的十天中了解到生活也有美好的缺陷。高山峻岭的陡峭边缘,午后骤降的冰雹风暴,都给人带来种种不便,但是却为登山旅途增添了几分妙趣。我敏锐地感觉到,在我追求完美事业的过程中,我往往没有认识到,不完美的地方也是我们自身的核心特质,需要保留下来,而不是经常改变。

In the episode "The Little Kicks," we get to see Elaine's fabulously hilarious dance moves. It's almost impossible to imagine a version of Seinfeld in which Elaine doesn't dance in such a funky way. And yet shockingly, this was almost the case. Writer Spike Fereston knew that series creator Larry David was against the dance, and he was only able to get it approved after David left. He was able to get the dance approve, but still received a lot of push back from the other writers.
