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

Major pharmaceutical companies, working with the American Cancer Society, will steeply discount cancer drugs for patients in African countries. Cancer kills 450,000 people across the continent each year, but many types here are among the most treatable: breast, cervical and prostate tumors.

“这让编辑以为文章发送给了该学科真正的评审人。我们与真正的评审人进行调查和沟通后,他们确认并没有对论文做过评审。

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.

This is probably true -- and only serves to make him that much more attractive to the ladies.

I formerly had an Android device (even though I have had a MacBook since 2009 – weird, I know). After switching this summer, I quickly realized the power of iPhone “Reminders.” Each time a reminder is due, your iPhone buzzes and displays a pop-up. You can snooze it or mark as completed. In addition, you can set up recurring reminders, which are perfect for remembering to mail estimated quarterly tax payments, renewing subscriptions, running payroll and other things you tend to forget.

Yes, even if real GDP growth does not. Speculation over the true GDP growth rate in China, as opposed to the official one, has spawned a cottage industry of specialist economists. The official figures are deceptively stable and serene thanks to suspected “smoothing” by the Chinese authorities, as they bend the figures to fit growth targets. So even if growth does stumble in 2018, the official growth rate is almost certain to come in above the preordained 6.5 per cent.
