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 FORBES Global 2000 is a comprehensive list of the world’s largest, most powerful public companies, as measured by revenues, profits, assets and market value.

1870年3月19号,轮滑登上杂志《科学美国人》。它的制作人是伊利诺伊州奥尔尼的托马斯·呂德斯,被称作"佩德速度",后来,轮滑的轮变得小了很多,直径约为36厘米(15英寸)。吕德斯身材高大魁梧,他说自己用轮滑一直滑2个小时也不觉得累,同时他也说每一个人都可以滑轮滑,不论他们是什么体型。另一种轮滑出现在1923年,它的轮子在脚的内侧,而非外侧。(除了轮子的尺寸不一样以外,两种轮滑最主要的差别在于:由战车溜冰公司制作的轮滑,小轮在大轮的后面,增强整个轮滑的稳定性。)

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.

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.
