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

"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."

In an electoral system corrupted by money, media, and parties, the US people are offered a choice every four years between two hideously awful candidates for an office that increasingly resembles an imperial throne. And increasingly the primary motivation of voters is to oppose the candidate they believe is the greater evil.

Which is not to say that the Obama era has meant an end to law enforcement. On the contrary: In the past few years, the administration has allocated massive amounts of federal resources to catching wrongdoers - of a certain type. Last year, the government deported 393,000 people, at a cost of $5 billion. Since 2007, felony immigration prosecutions along the Mexican border have surged 77 percent; nonfelony prosecutions by 259 percent. In Ohio last month, a single mother was caught lying about where she lived to put her kids into a better school district; the judge in the case tried to sentence her to 10 days in jail for fraud, declaring that letting her go free would "demean the seriousness" of the offenses. So there you have it. Illegal immigrants: 393,000. Lying moms: one. Bankers: zero. The math makes sense only because the politics are so obvious. You want to win elections, you bang on the jailable class. You build prisons and fill them with people for selling dime bags and stealing CD players. But for stealing a billion dollars? For fraud that puts a million people into foreclosure? Pass. It's not a crime. Prison is too harsh. Get them to say they're sorry, and move on. Oh, wait - let's not even make them say they're sorry. That's too mean; let's just give them a piece of paper with a government stamp on it, officially clearing them of the need to apologize, and make them pay a fine instead. But don't make them pay it out of their own pockets, and don't ask them to give back the money they stole. In fact, let them profit from their collective crimes, to the tune of a record $135 billion in pay and benefits last year. What's next? Taxpayer-funded massages for every Wall Street executive guilty of fraud?

Eating locally grown produce is a fine thing in many ways. But it is not an end in itself, nor is it a virtue in itself.
