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.

在令人失望的2014年里,基金投资者们没有太多的动作。总体而言,过去11个月中,主动选股基金仅新增了350亿美元资金,还不到2013年同期新增资金(1620亿美元)的四分之一。2013年是该行业自2007年以来首次实现资金净流入。不过,这并不是说基金行业毫无作为。截止感恩节,交易所交易基金(ETFs)和被动指数型基金吸纳了2060多亿美元净存款,行业领先者先锋集团管理的基金规模在今年夏末突破了3万亿美元大关。投资者们似乎已经决定,与其把宝押在“骑手”身上,不如直接把赌注押在“赛马”身上。

Graham Allison, the famous Harvard professor, also warned that east Asia was headed towards the “Thucydides Trap”, adding: “When a rapidly rising power rivals an established ruling power, trouble ensues.” In early 2013, the then prime minister of Luxembourg, Jean-Claude Juncker, warned that 2013 was looking dangerously like 1913. The Economist also warned at the end of 2013, “A century on, there are uncomfortable parallels with the era that led to the outbreak of the first world war.”

A lighthearted rom-com starring Adam Sandler and Drew Barrymore is the last thing you'd expect to mirror real life, but this comedy was in fact partially based on a true story. Sandler plays a veterinarian who falls in love with Barrymore, an amnesiac whose memory resets at the beginning of each day. He learns that Barrymore has replayed the same day over and over again since a car crash left her with a traumatic brain injury. Upset by the lie she has been living, Sandler's character makes a series of videos that explain her accident and her life for her to watch each morning.

Tiemba is also ranked second for career progression and fourth for work experience.
