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

So many are tuning out. Denial. Truth is, bubbles are everywhere. Ready to blow. The evidence is accelerating, with only one obvious conclusion: Max 98% risk at a flashpoint. This 2014 crash is virtually guaranteed. There's but a narrow 2% chance of dodging this bullet.
It has now entered the top 20 for the first time.

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.

White people’s officially privileged status waned over the latter half of the 20th century with the demise of discriminatory practices in, say, university admissions.

Along with her friend Chloe, Max is out to uncover the truth behind the mysterious disappearance of fellow student Rachel Amber. With an indie-film feel and an eclectic soundtrack, Life Is Strange stands out from other games by blending the angst of being a teenage girl today with life-and-death situations, and the ability to rewind time. While this gameplay mechanic has been used in many games before, this take on time manipulation feels as unique as the American characters the French developer has created.

Why was I so confident that there would be no war in east Asia, either in the East China Sea or the South China Sea? The simple answer is that I know the Asian dynamic. While many Asian neighbours will make angry nationalist statements (and they have to do so to manage popular nationalist sentiments), they are also careful and pragmatic in their deeds.

'Short Term 12' is one of those small indie features that stays with you in a big way. It's only 96 minutes long, a modest production set in a foster-care facility for troubled teens.

Ms. Larson is almost a sure thing for not getting an Oscar-this year's competition is unusually fierce-but do catch up with her portrayal of Grace, a 20-something supervisor who is far from untroubled in her own life.
