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

理查三世的遗骨将在当地教堂被正式重新埋葬。他一直被视为英国历史上最残酷的暴君之一,威廉-莎士比亚将其刻画为“驼背的暴君”。

安娜的头发比查斯顿本来的发色浅,有时安娜向后撩头发时会露出这两个层次,有点戏谑,但仍不失威严。
中国民航局局长冯正霖表示,因天气造成航班延误的比例由2015年的29.5%增至2016年的56.8%。

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.

本周一,研究小组表示,根据遗骨可以看出,理查三世患有严重的脊柱侧弯,或者说脊柱弯曲。这会让他十分痛苦,还会导致右肩比左肩高,但莎士比亚的《理查三世》中描述的枯萎的手臂却无从证实。

Wray and O’Brien saw the way users eagerly engaged with their branded emojis, and believed advertisers appreciated the convenience of using one vendor to get many different messaging apps.

According to government sources, property sales in Hong Kong fell almost 40 per cent in the first half of the year compared with the same period in 2015 — both in terms of price and volume. An index from the Rating and Valuation Department released this month showed the commercial sector was a particular casualty, with prices falling 5.7 per cent in May compared with the same month last year.
Until now, the appeal of Bigcommerce’s eponymous technology has been simplicity and its ability to scale along with merchants as they grow. “To some, this will mean the difference between success and failure,” said Steve Case, who as a board member advises Bigcommerce on U.S. entrepreneurial trends. “Even just five years ago, if you wanted to create a compelling offering, it could cost hundreds of thousands of dollars. Now, you can get up and running in hours for less than $100 per month.”

预测人士期望2014年能够成为经济实现突破的一年。但经济能否最终摆脱低迷的增长,还要取决于几个因素出现与此轮复苏刚开始时不一样的表现。以下是其中的几个关键因素:
