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

在2014年开始的这轮放缓之前,中国的雇主对于奖金没有这么吝啬。奖金的数额会大大高于一个月的薪水,让回家度假的员工能拥有足以为长辈和其他家庭成员购买礼物(或存为积蓄)的现金。

Chile were one of the most exciting teams at the 2010 World Cup and recentky gave England the run around at Wembley, whilst if Colombia can get Radamel Falcao fit then they could cause an upset or two. So of all the South American teams, only Ecuador look like they might struggle to get out of the group stages, with all the others more than capable of reaching the latter stages.

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.

客户通过Twitter 和Faceboo向世界传播“糟糕经历”的能力已经改变了客服世界的生态。尼尔森公司(Nielsen)2012年的一项调查显示,超过一半的客户现在通过社交媒体寻求补救措施;与此同时,在Twitter上提出问题或抱怨后,大约81%的用户提出当天就能获得回应。但在今年秋天,事情变得更加有趣:9月2日,英国航空公司(British Airways)乘客赛义德?哈桑斥资大约1,000美元,购买了几条“推广消息”,猛烈抨击这家航空公司弄丢了他的行李。鉴于有偿社交媒体推广现已成为客户的新武器,从2014年开始,各大航空公司、信用卡公司、银行和其他累犯提供的糟糕透顶的客户服务或将走向终结。无穷无尽的电话等待时间和那些自动化的“电话树”(比如,“英语服务请按1,西班牙语服务请按2,您整整一个下午都需要等候接听请按3”)或许将被扔入历史的垃圾桶。

There has also always been a certain fluidity to this concept of whiteness. Irish and Italian immigrants to the United States, and Jews in Britain, were once seen as separate from the white national majority, and are now generally considered part of it, benefiting from racial privilege. At the same time, Jews’ white skin did not protect them from being cast as outsiders by some of Mr. Trump’s supporters who have circulated anti-Semitic memes on social media.

The developer behind Kinect Disneyland Adventures and Elite: Dangerous is taking the theme park business to the extreme in ScreamRide. The game lets players build outrageous roller coasters, thrill rides and attractions from the ground up and then take them for a test run. The game offers three ways to play: Engineers can construct elaborate rides that test the boundaries of physics and g-forces; Scream Riders get on these rides and experience the thrills and spills first-hand – sometimes resulting in untimely deaths; and Demolition Experts can use any means necessary to tear down an entire amusement park. With classic PC games like Roller Coaster Tycoon now playable on smartphones, this next generation of thrill-ride creator is a welcome interactive experience. It’s always fun to build, ride and destroy roller coasters – and ScreamRide offers plenty of ways to share the thrills with your friends.
