How can we measure what makes a school system work? Andreas Schleicher walks us through the PISA test, a global measurement that ranks countries against one another -- then uses that same data to help schools improve. Watch to find out where your country stacks up, and learn the single factor that makes some systems outperform others.

Science, government and private enterprise are asking if they can predict future events by creatively crunching massive amounts of data made available by you, the individual. As people post more and more information online, computers are getting better at extracting and analyzing data to predict crime rates, stock market fluctuations, the spread of disease, political elections, revolutions and more. Professor Johan Bollen, who developed a method of using Twitter to predict market changes, describes the information revolution as 'a gold rush'. What's the Big Idea?
