On March 10, 2010 the National Governors Association, the Council of Chief State School Officers, Achieve, and other organizations issued draft Common Core Standards (CCS) for K-12 mathematics and reading. We at CEMSE have examined the mathematics standards for Grades K-6 and have found them to be seriously flawed. If we are to have national standards, then those standards should be designed to prepare students for life in the 21st century. We believe that the proposed CCS standards for mathematics in Grades K-6 would promote a back-to-basics curriculum that ignores the profound changes that have taken place in the last...

Advanced Abacus Malcolm A. Kline, March 15, 2010 The Washington, D. C. suburb of Montgomery County, Maryland is one of America’s richest—in dollars. Its’ public school curricula is a bit more impoverished. “A top Montgomery County schools official has called the district’s tenacious and much-publicized push for all middle school students to complete high-level mathematics a ‘mistake,’” Leah Fabel reported in The Washington Examiner. Specifically, Susan Marks, the district’s associate superintendent for human resources and a former teacher and principal said that “One mistake that we did make is that we pushed every kid into eighth-grade algebra.” “Hallelujah,” Gordon Brenne,...

Princeton engineers have made a breakthrough in an 80-year-old quandary in quantum physics, paving the way for the development of new materials that could make electronic devices smaller and cars more energy efficient. By reworking a theory first proposed by physicists in the 1920s, the researchers discovered a new way to predict important characteristics of a new material before it's been created. The new formula allows computers to model the properties of a material up to 100,000 times faster than previously possible and vastly expands the range of properties scientists can study. "The equation scientists were using before was inefficient...

Seattle's so-called "Discovery" math curriculum doesn't add up for a King County Superior Court judge, who rejected the style of instruction Thursday and ordered the district to try again. Last May, the School board implemented a district-wide math curriculum called Discovering Math. The curriculum was part of a five-year strategic plan that Superintendent Dr. Maria Goodloe-Johnson created. But Judge Julie Spector ruled Thursday that the board's decision to use the Discovering series was arbitrary and capricious. She ordered the board to reconsider the matter. "The court finds, based upon a review of the entire administrative record, that there is insufficient...

Spurred by a succession of reports pointing to the importance of algebra as a gateway to college, educators and policymakers embraced “algebra for all” policies in the 1990s and began working to ensure that students take the subject by 9th grade or earlier. A trickle of studies suggests that in practice, though, getting all students past the algebra hump has proved difficult and has failed, some of the time, to yield the kinds of payoffs educators seek. Among the newer findings: • An analysis using longitudinal statewide data on students in Arkansas and Texas found that, for the lowest-scoring 8th...

Interesting. From this book (sorry, not all of the formulas converted right): Mathematical Signatures in Nature: A Sign of Design? “[The Universe] is written in the language of mathematics, and its characters are triangles, circles, and other geometrical figures, without which it is humanly impossible to understand a single word of it...” – Galileo Galilei1 Math is the universal language, but it is not a human construct. Sure, we create symbols for numbers and mathematical computations, but math itself is more fundamental. 2 + 2 = 4 is universally true, universal in the sense that everywhere in the universe it...

Based on the fact that neither of the two primary political parties in the U.S. seem to know or care about the very limited constitutional powers of the federal government today, it’s not hard to understand why many American patriots are seeking a silver bullet in the form of a new political party. But how realistic is that idea, or more accurately stated, is it a dangerous road to go down?

Making the World's Knowledge Computable Today's Wolfram|Alpha is the first step in an ambitious, long-term project to make all systematic knowledge immediately computable by anyone. Enter your question or calculation and Wolfram|Alpha uses its built-in algorithms and a growing collection of data to compute the answer. Based on a new kind of knowledge-based computing...

Okay, we have tons of algebra programs that can work with numbers but do not have any help with Story problems. Can anyone tell us the formula for solving this, step by step. Nine pounds of Sweet Potatoes cost the same as Six pounds of Apples. One pound of Sweet Potatoes cost twice as much as one pound of Onions. While a pound of Apples costs 24 cents more than a pound of Onions. (we can't solve it with NO integers) Can anyone tell us how to do this?

More city kids are graduating from high school, but that doesn't mean they can do college math. Basic algebra involving fractions and decimals stumped a group of City University of New York freshmen - suggesting city schools aren't preparing them... "These results are shocking," ... "They show that a disturbing proportion of New York City high school graduates lack basic skills." During their first math class at one of CUNY's four-year colleges, 90% of 200 students tested couldn't solve a simple algebra problem... Only a third could convert a fraction into a decimal. The lack of math skills means the...

This article is also available as a podcast. A Gömböc is a strange thing. It looks like an egg with sharp edges, and when you put it down it starts wriggling and rolling around with an apparent will of its own. Until quite recently, no-one knew whether Gömböcs even existed. Even now, Gábor Domokos, one of their discoverers, reckons that in some sense they barely exists at all. So what are Gömböcs and what makes them special? Balancing act The defining feature of a Gömböc is the fact that it's got just two points of equilibrium: one is stable and...

boom in affordable housing in the 1950s was helped by the invention of a distinctive multifunctional piece of equipment: the backhoe. Its strong yet relatively slender articulated arm allowed precise yet rapid placement for digging or lifting. The manipulative device is trim and fast, since hoses transfer power to it from a powerful hydraulic pump within the main chassis. The "arm" of the backhoe makes many people think the equipment design is similar to a human arm, but what makes it so versatile is that it is actually more like a giant human finger. If a valuable piece of equipment...

For many students, bungling more than half the questions on a test would mean an F and all that comes with it — months of remedial work, irksome teachers and, perhaps, a skimpy allowance. But on New York State’s math exam this year, seventh graders who correctly answered just 44 percent of questions were rewarded with a passing grade. What gives? Three years ago, the threshold for passing was 60 percent. In fact, students in every grade this year could slide by with fewer correct answers on the math test than in 2006. In math this year, 86 percent of...

Welcome to the party fellas. When the president says his plan won't add one dime to the deficit, will cover everyone, will allow you to keep your plan, and will improve the quaIity of care, I usually start thinking that the unicorns will be here any minute. After the president's Hail Mary speech on Wednesday, the AP did a fact check and found many of his claims to be a stretch, at best. For example, on the assurance that "it won't add one dime to the deficit," AP notes that the Barry and the Dems are full of it.
