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

There’s nothing worse than a boss who says one thing and does another, and nothing better than one who keeps his word. Just as managers must trust their team, employees must trust their boss to have their best interests at heart。
Make sure you've got a good plan for seeing that your children are cared for when you're scheduled to be in class, and when you need to study. It really is possible to raise children while you're going to school. People do it every day.

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.

When he wasn't programming or doing schoolwork, D'Aloisio began to fill his spare time reading about natural language processing. He'd studied languages as diverse as Latin and Mandarin, and became fascinated by concepts like grammatical frameworks, morpheme parsing and the 1960s work of the linguist Richard Montague. 'He's my favorite,' D'Aloisio enthuses. 'He theorized that natural language could be described like a syntactical programming language.'

A study published in the journal "Clinical Psychological Science" in 2012 showcased the power of self-imagination, which showed the technique could help people with impaired memories, as well as individuals with no memory problems. As with other studies of human memory, the scientists asked participants to remember a list of words related to certain personality traits. The participants were then asked to use a specific strategy to help them recall the words. For example, some participants were asked to remember one personality trait by thinking of a second word that rhymed with the trait. Other participants were asked to remember the definition of the trait while others were asked to engage in "self-referential processing" where they would think about the trait in a personal, self-reflective way.

Beloved TV show characters enter our lives as friends and impact us in crazy ways. They can make us laugh until our sides hurt, cry when things don't go well for them, and call in sick to work when we just can't stop watching and must know what happens. But through it all, we love them. And yet, there's so much that the audience will never know. Some TV shows have dark secrets. Some almost didn't exist at all. Here are some behind the scenes stories of your favorite TV shows.

Yes — by an eyelash. Democrats will need to win an additional 24 seats, meaning they will have to hold on to all 12 Democratic districts that Mr Trump won last year and pick up the 23 Republican districts that voted for Hillary Clinton, plus one or two more for good measure. The math is not on the Democrats’ side, but history is. The president’s party almost always loses some House seats in the midterms, and sometimes loses big, especially when the president has an approval rating below 50 per cent. See Barack Obama in 2010.

勇士的横扫,实际上让那些试图挑战勇士的球队无力追赶勇士的脚步,致使联盟在季后赛收入上损失惨重。于是,总决赛便成了战胜勇士的最后的希望,也是最后的机会。总有些愚蠢的人通过不断告诉你不要低估了勒布朗·詹姆斯来让你重燃希望。我看了所有五场詹姆斯在的总决赛,我现在客观的告诉你:詹姆斯知道自己赢不了。“我能做什么?他们赢了73场比赛,我打败了他们,于是他们引进了凯文杜兰特。”在凯文杜兰特用自己的冷血投射杀死系列赛之前,骑士还设法在三场比赛中夺得了一场胜利。但最后,骑士队虽然避免了横扫的尴尬,但他们结束赛季的方式也只能用虎头蛇尾来形容。
