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

adj. 受影响的,受感动的,受疾病侵袭的 adj. 做

Talented getaway driver Baby (Ansel Elgort) relies on the beat of his personal soundtrack to be the best in the game. After meeting the woman (Lily James) of his dreams, he sees a chance to ditch his shady lifestyle and make a clean break. Coerced into working for a crime boss (Kevin Spacey), Baby must face the music as a doomed heist threatens his life, love and freedom.
In short, the period was so far like the present period, that some of its noisiest authorities insisted on its being received, for good or for evil, in the superlative degree of comparison only.

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 new money is interested in old masters, but it wants what Duveen sold to the robber barons. It wants names,” said Hugo Nathan, a co-founder of the London advisers Beaumont Nathan. He was referring to Joseph Duveen, the British art dealer who was responsible for bringing many great works of art to the United States.

Danny Boyle (“Slumdog Millionaire”) created this satirical drama, which bears some resemblance to Armando Iannucci’s political comedy film “In the Loop.”

Since 2001, I’ve helped direct an annual 建筑材料行业:中央经济工作会议影响分析 recognizing top social entrepreneurs: those who develop effective, original approaches to dealing with social problems and who rely mainly on private funding and volunteers to see their ideas to fruition. They are leaders of America’s civil society, doing the things that government can’t do—or can’t do as well.

In one example, Christie’s was offering the mid-18th-century canvas “Rebecca and Eliezer at the Well” by the Venetian artist Francesco Fontebasso at a low estimate of 120,000. The pleasant piece of rococo decoration had been bought at auction in 1990 for $286,000, according to Artnet. At the Dec. 8 sale it fell to a single telephone bid of 115,000, about $170,000, before fees. Investors do not expect to incur a loss of about 40 percent a quarter century after buying a Warhol or a Basquiat. Reselling an old master can be even harder when that painting has been languishing in a dealer’s gallery.

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.
Managers are expected to manage the people below them on the corporate hierarchy, but the best managers also have ways of managing their superiors and coworkers on behalf of their team. Many times this means effective communication, managing expectations, and requesting help in a timely manner。
