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

Global warming and a powerful El weather event combined to make 2015 the planet’s hottest year since modern records began in the 1800s, according to scientists, who warned this year could be even warmer.

周边环境:这栋房屋坐落在摩德纳岛(Modena Island),距萨凡纳市中心大约20英里(约32公里)。据该房源的代理人说,该社区设有门禁,在栎树丛与咸水湿地之间坐落着大约20栋房屋。摩德纳岛是斯基达韦岛(Skidaway Island)的一部分,岛上有一座由佐治亚大学的海洋学研究所和一座大型州立公园。

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.

But if the U.S. can avert that Washington-made crisis, the outlook for workers finding jobs is actually looking pretty good for next year. For one thing, the damage of superstorm Sandy will have to be repaired, meaning jobs in construction and retail. Businesses, meanwhile, which have held off investing and hiring because of uncertainty over the fiscal outlook, might finally open their wallets. That means more jobs, too.[qh]

To be sure, that excitement can certainly lead to unrealistic declarations from those in the community. Some bitcoin developers and investors proclaim that within five years, all the major banks will be accepting bitcoin. That’s a stretch, acknowledges Peter Smith, COO of the bitcoin wallet Blockchain (not to be confused with the actual bitcoin block chain). “I hear a lot of predictions about how soon the whole world will be using bitcoin, and most of the time, those are unrealistic,” he says. “What we’re trying to do as an ecosystem is incredibly audacious, so it’s going to take a lot of time.”

We'll start our review with the South American nations, and who else could we begin with, but the hosts Brazil. Rewind 18 months and they looked like they'd be struggling, but the appointment of 'Big Phil' Scolari has been inspired, and he's brought a belief to the team that was previously missing. Last years 3:0 demolition of Spain in the Confederations Cup final shocked many experts, and all of a sudden the Brazilians have expectations on them. Whilst you can't argue with that scoreline, we still wonder if Brazil have the firepower to win such a long tournament. Neymar is expected to conjure up the magic, but they're relying on Fred to come up with the goals. No disrepect to Fred, but the last two Brazilian teams to win the World Cup, in 2002 and 1994, could count on the likes of Ronaldo and Romario to lead the front line, two genuine legends of the game.

Remember, no one is ever perfectly prepared for every situation. You’ve probably discovered this by now. Your education gave you a foundation for the job, but growth happens in the trenches. Maybe you motivated your team not just to meet the new deadline, but to deliver extraordinary work. Perhaps you realized you had more poise than you ever expected in a client situation. Or, you suddenly discovered that you can capitalize on the relationships you’ve built and become a “rainmaker” for your organization. Before you can learn any of these things, you have to learn to say “Yes.” It’s okay to acknowledge the butterflies in your stomach; however, it’s not okay to let them stifle your growth.
