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

TextPride was a fine business, but a tiny one. Meanwhile, the market for messaging apps was exploding. Facebook FB 0.61% bought WhatsApp for $19 billion; that service now has 700 million monthly active users. Tango, an app with 250 million registered users, is worth $1.5 billion. Kik has 200 million registered users. Snapchat, worth $10 billion, has 100 million users. A new study, commissioned by Kik, shows that U.S. users now spend more time on average in messaging apps than they do on social networking apps. The only problem? These messaging apps need ways to make money, and there’s no reasonable way for advertisers to wedge themselves into conversations between friends.

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.

However, strong progress across the main rankings does not automatically translate into European success. Sa Business School at the University of Oxford, for example, rose one place in the MBA ranking, five places in the ranking of open executive programmes and broke into the top 10 of the Executive MBA ranking for the first time by moving up 12 places, but its European ranking remains unchanged, at 10th.

Every point we think we've reached where James cannot be better than he has been, he then blows past it like a poor center switched onto him. What will be discussed most is his all-encompassing skill, but this is also a testament to the work that James puts in. You can mock all those Instagram videos he puts up, but those are the real reason he's still able to do this; James has never cheated the game, not a day in his life, and the result is incomparable performance night in and night out.

Coca-Cola (KO, Fortune 500) Chief Executive Muhtar Kent thinks as both a first-generation American as well as a business leader that immigration reform is good for business. Kent outlined in a February USA Today op-ed how "lucky" he felt to be able to make his life in the U.S. and his belief that foreign entrepreneurs should have the same opportunity. The CEO wrote that he supports immigration reform because immigration is "an essential part of the growth calculus for this great country."
It is already illegal for employers to discriminate on the basis of race, color, sex, nationality, religion, age, or disability.

In a November Wall Street Journal op-ed entitled "Workplace Equality Is Good for Business," Cook urged the passing of a federal law to protect workers from discrimination based on sexual orientation.

Yes. There are plenty of positives: earnings, economic growth, and US tax cuts. But they are already known. Stocks look ridiculously expensive by historical standards, but that tells us nothing about short-term moves. Ultimately, it comes down to liquidity, which has driven markets since they emerged from the crisis in 2009. If all goes according to plan, central banks will be decreasing their balance sheets, and removing liquidity, by the end of 2018. If they go through with this, the odds are that the S&P will stall. But even a tiny tremor could make the bankers blink. Expect the momentum to continue.

首先,Bitstamp遭遇黑客袭击,以及2011年黑客袭击比特币交易平台Mt.
