Rarely is the question asked: is our kids competing?

"We sort our kids. We rate them. We chart them, and we measure their progress against the rest of the country and pray that they come out on the high end of the curve. And frankly, it's all horseshit. Every last bit of it. The competition industry is crushing us all." Drew Magary, at Deadspin, unloads on the idea that "these kids today" are little ninnies made soft by participation trophies and unscored soccer games. [more inside]

Who or what broke my kids?

Who or what broke my kids? "The basic premise of the activity is that students must sort cards including probability statements, terms such as unlikely and probable, pictorial representations, and fraction, decimal, and percent probabilities and place them on a number line based on their theoretical probability. I thought it would be an interactive way to gauge student understanding. Instead it turned into a ten minute nightmare where I was asked no less than 52 times if their answers were “right”. I took it well until I was asked for the 53rd time and then I lost it. We stopped class right there and proceeded to have a ten minute discussion on who broke them."

Accountability in the Indiana school system

"I hope we come to the meeting today with solutions and not excuses for me to wiggle myself out of the repeated lies I have told over the last 6 months." Tony Bennett, the Indiana Superintendent of Public Instruction, had a big problem. Christel House Academy, a public charter school in Indianapolis founded by time-share magnate and major GOP donor Christel DeHaan, had come in with a C on the state's A-F grading scale, thanks to poor scores by 9th and 10th graders in English and math. "They need to understand that anything less than an A for Christel House compromises all of our accountability work," Bennett wrote to a staffer. Fortunately, Bennett's team found a solution, revealed today in staff e-mails obtained by the AP -- change the state's grading scale so that the offending grades didn't count. Will Bennett be able to hold on as Indiana's top education official? Not to worry: in January, he moved on to the same job in Florida. [more inside]

The Museum of Mathematics

Last night was the grand opening of the Museum of Mathematics in New York City, the only museum of its kind in North America. The video is narrated by MoMath's chief of content, mathematical sculptor George Hart (better known in some circles as Vi Hart's dad.) The sculpture of the space of three-note chords in the video is based on the work of Dmitri Tymoczko, and the lovely curved hammock of strings a visitor is sitting in at the end is a ruled quadric surface. Many more videos at the Museum of Mathematics YouTube channel. Coverage from the New Scientist. (Previously on MetaFilter.)

Boaler and the math wars

"Milgram and Bishop are opposed to reforms of mathematics teaching and support the continuation of a model in which students learn mathematics without engaging in realistic problems or discussing mathematical methods. They are, of course, entitled to this opinion, and there has been an ongoing, spirited academic debate about mathematics learning for a number of years. But Milgram and Bishop have gone beyond the bounds of reasoned discourse in a campaign to systematically suppress empirical evidence that contradicts their stance. Academic disagreement is an inevitable consequence of academic freedom, and I welcome it. However, responsible disagreement and academic bullying are not the same thing. Milgram and Bishop have engaged in a range of tactics to discredit me and damage my work which I have now decided to make public." Jo Boaler, professor of mathematics education at Stanford, accuses two mathematicians, one her colleague of Stanford, of unethical attempts to discredit her research, which supports "active engagement" with mathematics (aka "reform math") over the more traditional "practicing procedures" approach.

Is teacher evaluation statistical voodoo?

"Value-added modeling is promoted because it has the right pedigree -- because it is based on "sophisticated mathematics." As a consequence, mathematics that ought to be used to illuminate ends up being used to intimidate." John Ewing, president of Math for America and former executive director of the American Mathematical Society, criticizes the "value-added modeling" approach used as a proxy for teacher quality, most famously in a Los Angeles Times story that called out low-scoring teachers by name. A Brookings Institution paper says value-added modeling is flawed but the best measure we have of teacher value, arguing that the metric's wide fluctuations from year to year are no worse than those of batting averages in baseball. (Though the weakness of that correlation is mostly a BABIP issue.) Can we assign a numerical value to teacher quality? If so, how?

Dangerous Ideas

Every day in August 2010, the chin-scratching blog Bigthink will post a "Dangerous Idea" supplied by one of its expert contributors. So far it has been suggested that we spike the water supply with lithium, darken the atmosphere to blot out the Sun, and leave lots of children behind.

Wal-Mart U

"I do math all day at Wal-Mart." From the Washington Post: "Under a program announced Thursday, employees of Wal-Mart and Sam's Club will be able to receive college credit for performing their jobs, including such tasks as loading trucks and ringing up purchases." Dilution of the meaning of higher education, or laudable way to spread credentials to people without the opportunity to attend traditional college? Or both?

Back to self-school

The autodidact course catalog. Twenty-two professors at Johns Hopkins propose reading lists for courses of self-study, from "Society Can Be Dangerous To Your Health" to "Higher Mathematics in Nouns and Verbs" to "Biochemistry and Human Evolution (with Rather a Lot about Mitochondria.)" If you're not going back to school this week, why not take on one of these syllabi instead?
