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

日本总体排名第五,是亚洲表现最优异的国家。“原动力”排名第五,“前瞻性”排名第一。
2013年日圆兑美元下跌21%,这为日本吸引来1,000万海外游客,尽管中日两国在东中国海(中国称东海)存在领土争端,然而这些游客中有许多是来自中国的富人。

全国具有大学教育程度的人口达17093万人,每10万人中受过高等教育的人口已由2010年的8930人上升至2015年的12445人。此外,我国上过高中的人数也有所增长,而只完成低水平教育的人数则有所下降。
拍卖行称这次拍卖会还将拍卖两颗超过100克拉的钻石,吸引了30多个国家的买家。

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.

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.
菲律宾参议院一委员会就国内发生的法外处决事件举行了听证会,罗纳德?德拉罗萨(Ronald Dela Rosa)在会上表示,自7月1日杜特尔特就任总统后,有712人在警方缉毒行动中被杀,还有1067起死亡正被作为与毒品相关的自告奋勇者杀人案件在调查中。
I'm only a child yet I know if all the money spent on war was spent on ending poverty and finding environmental answers, what a wonderful place this earth would be! 我只是一个小孩,然而我知道,要是把花在战争上的钱,用在找寻环境问题答案上来,或用在结束贫穷并找到解决的方案上来,这个星球将是个多么美好的地方啊!
o 特斯拉的规模越大,运营的复杂性就越强。由于它直接销售给终端顾客,免去了特许经销商的环节,它必须开发一个自己的服务中心网络来进行售后维修保养。另外它独特慷慨的保修条款规定,车主在使用三年后,可以以原价50%的价格将车卖还给特斯拉。这种做法可能会催生一个二手特斯拉的专门渠道。“寻找阿尔法”上的一位博主写道:“等到车主觉得他们的车不像一年前那么诱人和罕见,特斯拉可能会吃进大量有三年车龄的二手车。在我看来,这是个潜在的麻烦。”

Those will provide essential and productive lessons.

如果你的确需要招募很多自由职业者来为你打短工,那么你或许考虑过,干脆把服务外包流程也外包出去。市面上有好几家不错的公司从事这样的服务,每家都有不同的业务模式。比如,Bolton Remote公司能为你组织起一支经过审查的离岸承包商队伍。另一家提供商Hubstaff会评估你的项目,然后为你匹配合适的项目专家。使用就业外包服务可以节省你的时间,从而让你不必自己从事招募这一套流程。这些公司一般提供免费的招聘和就业外包服务,但是会从计时工资中抽取一定提成。
