"The United States never led the world. It was never number one and has never been close to number one on international math tests. Or on science tests, for that matter. It is more accurate to say that the United States has always trailed the world on math tests."

Educational researchers at the Technical University of Munich (TUM) have found that schoolchildren can independently develop strategies for solving complex mathematical tasks, with weaker students proving just as capable as their stronger classmates. Researchers in mathematics education worked with approximately 1600 8th grade high-school students in various German states. Following an introduction to the general topic by their teachers, the school children were given a workbook of geometric tasks that they had to solve on paper and using a computer over four school periods. Calculating the surface area of Gran Canaria was one of the real-world, free-form assignments the students had to tackle. The workbook material included explanations and examples of various problem-solving approaches. The teachers took a back seat during the session but were on hand to answer questions from the children, who worked in pairs. After testing the students' skills before and after the session, the researchers recorded a significant improvement in their capabilities. The students learned to apply mathematics more effectively, the researchers said. The students were also able to call on these skills in a further test three months later. "We expected students who were weaker at math to benefit more from a greater degree of guidance through the module," said professor Kristina Reiss.  "But we didn't see a significant difference between these and stronger students." The researchers also found that there were also no differences between boys and girls. "We now know that students - also those who are weaker in math - have the skills to master even very complex subject matters at their own pace," said Reiss. Topics: Cognitive Science/Neuroscience

Long thought to be off limits to science, morality has been considered the exclusive preserve of philosophers and theologians. Not any more. In this special report a new generation of scientists share their wide-ranging insights.

Take this pop quiz on world religions. It shows why we should not rush to inflammatory conclusions about any faith.

http://www.ted.com Alleviating poverty is more guesswork than science, and lack of data on aid's impact raises questions about how to provide it. But Clark Medal-winner Esther Duflo says it's possible to know which development efforts help and which hurt -- by testing solutions with randomized trials.  

NEW YORK - A standoff near Wall Street between protesters opposed to what they say is corporate greed and police may drag on into winter, with a march on police headquarters the likely next test of whether tensions escalate.

A methodology and philosophy of revolution is neither born nor accepted overnight. From the moment it emerges, it is subjected to rigorous tests, opposition, scorn and prejudice. The old guard in any society resents new methods, for old guards wear the decorations and medals won by waging battle in the accepted manner. Often opposition comes not only from the conservatives, who cling to tradition, but also from the extremist militants, who favor neither the old nor the new.

ABOUT THIS PROJECT For years, the Yes Men have been tinkering with side-splitting mischief as a way to fight injustice. Our latest film about those efforts, The Yes Men Fix the World, won lots of awards and was released all over the planet... but it simply did not fix the world.  So a year ago, we decided that showing what we do wasn't enough: we needed to help people to actually do it themselves. We called our idea The Yes Lab for Creative Activism. It's a factory for meaningful mischief, and a system for helping organizations and individuals carry out Yes Men-style actions on their own, to get media attention for important issues. But the Yes Lab is more than that: it also aims to help YOU take action on issues of social importance. Today, after a year of testing and nearly a dozen successes, we're proud to announce that the Yes Lab is ready for prime time! It's got a set of cool tools in development, that will soon help YOU get involved in new Yes Lab projects, and even to launch them. And it's got a new home at NYU, with space, lots of eager participants, and an ambitious new structure that will soon be cranking out many new projects. The trouble is that in spite of all that, we still have zero budget for the first round of projects themselves! And that's why you're reading this now. We're asking for $10,000, to make the all-new Yes Lab the lean, mean, change-making machine it can be. Any amount raised over $10,000 will bankroll projects beyond the first round.
