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

排放量去年的增幅比过去十年中2.5%的平均增长率略低,而且排放量增幅之所以下降,很大程度上是由中国经济增长放缓所引起的。中国是世界上最大的温室气体排放国。可能还需要再花一到两年时间,才能弄清楚中国排放量的增长究竟有没有放缓,还是最近数年那种极高的增速仍会持续。
Meanwhile, producer prices were deflating at a rate of -5.9 per cent, a six-year low, for a third straight month.

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.

Influenced by the current economic situation, and resource relocation in China's financial market, the banking industry is away from the high-speed growth period, the expert added.
We'll start our review with the South American nations, and who else could we begin with, but the hosts Brazil. Rewind 18 months and they looked like they'd be struggling, but the appointment of 'Big Phil' Scolari has been inspired, and he's brought a belief to the team that was previously missing. Last years 3:0 demolition of Spain in the Confederations Cup final shocked many experts, and all of a sudden the Brazilians have expectations on them. Whilst you can't argue with that scoreline, we still wonder if Brazil have the firepower to win such a long tournament. Neymar is expected to conjure up the magic, but they're relying on Fred to come up with the goals. No disrepect to Fred, but the last two Brazilian teams to win the World Cup, in 2002 and 1994, could count on the likes of Ronaldo and Romario to lead the front line, two genuine legends of the game.

William Leung, portfolio manager at Cohen & Steers, the US investment house with $4bn of assets exposed to Asia, agrees. He argues that speculative investment will be driven out of the market as prices fall. He adds that a trend in the industry towards alternative investments should mean that the price of real estate investment trusts rises even if the value of underlying assets grow more slowly. “We don’t think this correction will be so sharp,” he says.
Whatever the underlying cause, last year’s extreme warmth in the West meant that Alaska, Arizona, California and Nevada all set temperature records. Some parts of California essentially had no winter last year, with temperatures sometimes running 10 to 15 degrees above normal for the season. The temperature in Anchorage, Alaska’s largest city, never fell below zero in 2014, the first time that has happened in 101 years of record-keeping for the city.
