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

年度最佳单曲:米兰达·兰伯特《Over You》
库迪斯和沃斯在孜孜不倦分析荷兰金融记录的过程中得出了结论,悲观者和乐观者之间真正的区别在于他们是否亲身经历过这样的痛苦过程。库迪斯认为,可以类比的是那些经历过大萧条的人们的行为:这些人在大萧条梦魇过去后的几十年里,一直回避金融风险。

阿姆斯特丹危机始于荷兰Seppenwolde银团对东印度公司的股价做出了巨额的反向下注。这只股票在1771年早已大跌,主要是因为孟加拉的损失。但这家公司靠借钱继续支付高股息,掩盖了问题。Seppenwolde深信东印度股价会很快反弹,基于保证金大举买入该股。但它的股价并未反弹,在东印度公司降低了股息后,股价甚至进一步走低。
007系列电影荣誉主题曲之二:凯蒂·朗--《屈服》
进入2月以来,猛龙逐渐感到他们需要进行人员调整了:良好的开局已经被挥霍的差不多了,他们的防守不足以限制对手,他们在四号位有个巨大的漏洞,在凯尔-洛瑞即将成为自由球员之前,他们急迫的需要利用好他的巅峰期。

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.

Cannes' heckles and jeers are famous and the first film to fall foul of this tough crowd was Gus Van Sant's Sea of Trees, which was greeted by a storm of raspberries and thunderous boos at its press screening. Because these take place before a film receives its black-tie premiere, word quickly gets around and can cast a pall over the big event. When Naomi Watts and Matthew McConaughey took their turn on the red carpet, it had “a horrifically compelling walk-of-shame quality” according to the Daily Telegraph. But the Texan actor put on a brave face at a press conference shortly afterwards. “Anyone has as much right to boo as they do to ovate,” he said. I think we know what he meant.

Despite the overall upward trends in financing, the amount of capital raised by women-owned businesses has historically lagged when compared to men. For example, in the first half of 2013, women made up only 16 percent of businesses seeking funding, with only 24 percent of the women receiving angel funding, Plum Alley, an online e-commerce platform for female entrepreneurs, recently launched a crowdfunding platform specifically focused on helping women innovators get to the next level. And as the first platform of its kind in the exploding crowdfunding space (expected to hit $3.98 billion next year), we can certainly expect Plum Alley to play a big role in the entrepreneurial landscape for women in the year to come.

Goldie Blox is a toy company on a mission to redefine the “pink aisle” in toy stores. Men dramatically outnumber women in science, technology, engineering and math (STEM) education and careers, with girls largely losing interest in these topics by age 8. Goldie Blox toys are designed to inspire future engineers by engaging girls in a way that draws on their strong verbal and storytelling skills — while still offering opportunities to build the skills that can later translate into an interest in engineering. And speaking of opportunity, how does a start-up toy company stand out against the big names that have been dominating the toy space since the beginning of time? In a savvy move, Goldie Blox recently released a video that went viral with their take on the Beastie Boys song “Girls.” Though the video was ultimately taken down, Goldie Blox did an excellent job raising awareness of the need to get more women and girls interested in STEM … and of the Goldie Blox toys.

Remedy: Make a budget. If you don’t know how much money you need to live the lifestyle you feel comfortable with, you can’t accurately project whether switching jobs for a $10K pay bump is actually a good deal. Making a pros and cons list when comparing your current job with a new opportunity is also helpful. If the only advantage a job offers is a bigger pay check, you can weigh that against longer hours, a more onerous commute and increased reporting responsibilities. Keep in mind that research shows that increases in happiness based on earnings peak at about $75K. Incomes above this level don’t increase your feeling of well-being on a day-to-day basis. So, if you think a jump up to $85 or $90K will make you feel less morose when your alarm goes off, you might want to look at addressing some of the non-monetary factors in your life that are contributing to your dissatisfaction.
