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

"The editors thought the articles were being sent out to genuine reviewers in the discipline," he said. "Following our investigation and communication with the real reviewers, they confirmed they did not conduct the peer review."

Chris Washington, played by London-born Daniel Kaluuya, is drawn into the sinister underbelly of a small American community.

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 the economic picture has brightened considerably in Arizona, as the housing market stabilized and unemployment hit a post-recession low of 7.8% in May. As part of Forbes’ annual Best States for Business, we look at 35 factors to determine the best and worst states, including projected employment. Arizona is expected to have the fastest job growth at 3% annually over the next five years, according to Moody’s Analytics. The job gains are projected to boost household incomes 3.6% annually through 2017, which ranks second best in the U.S. after Illinois. The added jobs also go hand-in-hand with the state’s economic growth, which Moody’s forecasts to expand at a U.S.-best 4.6% annually.

The number was 34 percent higher during the same period last year, the report said.

Federal, state and local government job cutbacks are slowing. More than 250,000 workers at all levels of government lost jobs last year. This year, so far, about 20,000 have gained jobs. Worries about the nation's debt and deficits likely will keep a lid on government spending and investments, economists say, but any jumps in, say, infrastructure spending would create jobs. At the least, government will be less of a drag.[qh]

According to Oliver Cooke, a financial-services recruiter at Selby Jennings in New York, banks have been stressing what they call “internal mobility”, or redeploying staff from one department to another. If a bank facing sluggish conditions in debt trading, for example, can convert a trader to a risk analyst or a compliance officer, it can keep people interested — and it can save a bundle on severance.

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.
