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

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

BALTIMORE, June 20 - Mayors from around the US met in Baltimore this week to set public policy for the billions of people living in big cities, depending on municipal services to stay safe. While Congress considered allocating another $118 billion to conduct wars next year - and President Obama absurdly maintained that the costly bombing of Libya is not an act of war, and thus not subject to Congressional oversight - mayors listened to the people.

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.

I'm genuinely excited today to announce the release of my new book, With Liberty and Justice for Some: How the Law is Used to Destroy Equality and Protect the Powerful. As of this morning, it is available in bookstores as well as for shipping online. The book focuses on what I began realizing several years ago is the crucial theme tying together most of the topics I write about: America's two-tiered justice system - specifically, the way political and financial elites are now vested with virtually absolute immunity from the rule of law even when they are caught committing egregious crimes, while ordinary Americans are subjected to the world's largest and one of its harshest and most merciless penal states even for trivial offenses. As a result, law has been completely perverted from what it was intended to be - the guarantor of an equal playing field which would legitimize outcome inequalities - into its precise antithesis: a weapon used by the most powerful to protect their ill-gotten gains, strengthen their unearned prerogatives, and ensure ever-expanding opportunity inequality. This is how I described that development in the book:
