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 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 Lost Tomb is an action and adventure TV adaption of a popular online novel by Xu Lei. This is the first seasonal online TV series in China and the novel is scheduled to be dramatized in eight seasons, one season for each year. The first season was released in June of 2015. The novel series of the same name is about several people`s adventure in ancient tombs, and it enjoyed a wide readership since it was released online in 2006. Thus the adapted TV series had been accordingly highly expected by its fans but turned out to be disappointing. Although there were 24,000,000 hits on the web within the first two minutes of its debut, the season was later criticized by the audiences for its weak storyline and poor quality. Some lines of the series even became jokes on the social media.

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.
