Homeland Security threat

The Miami Herald has uncovered a new Homeland Security threat--and it's U.S. Customs and Border Protection agents that are committing crimes. Bribery, drug trafficking, migrant smuggling, embezzlement, and other crimes have become so prevalent that a senior manager has issued a memo pointing out that agents are supposed to uphold, not break the law:

U.S. Customs and Border Protection is supposed to stop these types of crimes. Instead, so many of its officers have been charged with committing those crimes themselves that their boss in Washington recently issued an alert about the ''disturbing events'' and the ``increase in the number of employee arrests.''

Thomas S. Winkowski, assistant commissioner of field operations, wrote a memo to more than 20,000 officers nationwide noting that employees must behave professionally at all times -- even when not on the job.

''It is our responsibility to uphold the laws, not break the law,'' Winkowski wrote in the Nov. 16 memo obtained by The Miami Herald.

IJ defends Speechnow.org

Speechnow.org is being supported by the Institute for Justice and the Center for Competitive Politics in its lawsuit against federal laws and regulations which forbid it from receiving more than $5,000 in donations per year from any individual and require it to file forms and engage in reporting in order to do what it wants to do.

What does Speechnow.org want to do? It wants to advocate the view that voters should vote for candidates who support the First Amendment and against candidates who do not. It takes no corporate or union money, it doesn't donate to or coordinate with individual candidates or political parties. Yet this is sufficient under current law to restrict its activities and entangle it in red tape, so Speechnow.org has filed a federal lawsuit seeking a preliminary injunction.

NSA's data mining and eavesdropping described

The March 10 Wall Street Journal contains a fairly detailed description of the data mining operation being run by the NSA. The program described is more data mining than eavesdropping, though it does involve the collection of transactional data like call detail records for telephone calls, and intercepted Internet data like web search terms and email senders and recipients. Also included is financial transaction data and airline data. I think most of this had already been pieced together, but this is a fairly comprehensive summary in one place. The WSJ story reports that leads generated from the data mining effort are then fed into the Terrorist Surveillance Program, which does warrantless eavesdropping. (An earlier version of this post incorrectly referred to the whole operation as the Terrorist Surveillance Program.)

School adopts Singapore math curriculum, sees gains in scores

Ramona Elementary in Los Angeles has adopted a Singapore math curriculum that includes a daily 60-second "sprint" drill to make some basic skills second-nature, and the result has been that the percentage of fifth-graders scoring at grade level went from 45% to 76% in two years. Singapore's students regularly score at the top in international math skill comparisons.

Ramona's students are mostly immigrants, with most of them from Central America; 6 of 10 speak English as a second language.
The books, with the no-nonsense title "Primary Mathematics," are published for the U.S. market by a small company in Oregon, Marshall Cavendish International. They are slim volumes, weighing a fraction of a conventional American text. They have a spare, stripped-down look, and a given page contains no material that isn't directly related to the lesson at hand.

Standing in an empty classroom one recent morning, Ramos flipped through two sets of texts: the Singapore books and those of a conventional math series published by Harcourt. She began with the first lesson in the first chapter of first grade.

In Harcourt Math, there was a picture of eight trees. There were two circles in the sky. The instructions told the students: "There are 2 birds in all." There were no birds on the page.

The instructions directed the students to draw little yellow disks in the circles to represent the birds.

Ramos gave a look of exasperation. Without a visual representation of birds, she said, the math is confusing and overly abstract for a 5- or 6-year-old. "The math doesn't jump out of the page here," she said.

The Singapore first-grade text, by contrast, could hardly have been clearer. It began with a blank rectangle and the number and word for "zero." Below that was a rectangle with a single robot in it, and the number and word for "one." Then a rectangle with two dolls, and the number and word for "two," and so on.

"This page is very pictorial, but it refers to something very concrete," Ramos said. "Something they can understand."

Next to the pictures were dots. Beginning with the number six (represented by six pineapples), the dots were arranged in two rows, so that six was presented as one row of five dots and a second row with one dot.

Day one, first grade: the beginnings of set theory.

"This concept, right at the beginning, is the foundation for very important mathematics," Ramos said. As it progresses, the Singapore math builds on this, often in ways that are invisible to the children.

Word problems in the early grades are always solved the same way: Draw a picture representing the problem and its solution. Then express it with numbers, and finally write it in words. "The whole concept," Ramos says, "is concrete to pictorial to abstract."
...
Many eminent mathematicians agree. In fact, it is difficult to find a mathematician who likes the standard American texts or dislikes Singapore's.

"The Singapore texts don't make a huge deal about the concepts, but they present them in the correct and economical form," said Roger Howe, a professor of mathematics at Yale University. "It provides the basis for a very orderly and systematic conceptual understanding of arithmetic and mathematics."
So why aren't these books more widely used? The L.A. Times article linked above says that the main resistance comes from teachers. The curriculum is not easy to use without special teacher training:
Adding to the difficulty is that the Singapore texts are not as teacher-friendly as most American texts. "They don't come with teachers editions, or two-page fold-outs with comments, or step-by-step instructions about how to give the lessons," said Yale's Howe. "Most U.S. elementary teachers don't currently have that kind of understanding, so successful use of the Singapore books would require substantial professional development."

Although some U.S. schools have had spectacular results using Singapore texts, others have fared less well. A study found that success in Montgomery County, Md., schools using the Singapore books was directly related to teacher training. At schools where teachers weren't trained as well, student achievement declined.
This seems to be further evidence for the recent McKinsey study comparing education internationally that concluded that the best results are obtained by hiring the best teachers, providing them with training and support to get the best out of them, and then intervening to provide students who fall behind with support.

Interesting articles in The Economist

A few articles of interest from the last couple of issues of The Economist:

February 23, 2008: "Moral thinking," a summary of recent research that sheds light on human moral reasoning processes. Video here. (A related, more in-depth story is Steven Pinker's "The Moral Instinct" which appeared in The New York Times Magazine on January 13.)

March 1, 2008: "Winds of change," a summary of research to use breathalyzer technology to diagnose medical conditions.

"Telltale hairs," about new methods of forensics to use hair analysis to identify a person's location at a given time (based on water consumption--could drinking imported bottled water be used to thwart this?).

SkeptiCamp 2


On Saturday, March 22, the second SkeptiCamp will take place, in Castle Rock, Colorado. Reed Esau, one of the organizers presenters (also known as the originator of the celebrity atheist list), reports that the James Randi Educational Foundation will be sponsoring the event this time, and the list of likely speakers looks quite interesting:
Some of those who plan to present have posted their intentions: writerdd on 'How I Became a Skepchick', Gary on pareidolia, R. G. on the Family Tomb of Jesus, Abel on Weapons of Mass Deception, Linda Rosa on Therapeutic Touch, Larry Sarner with a legislative update (on naturopath licensing), Crystal on a the new Fund for Thought initiative, Joe (a pediatrician) dispelling myths about vaccines and autism, Rocky Mountain Paranormal Society makes another appearance, Amy on why women need to be active in the skeptic movement, Jeanette on denialism, Rusty on the reproduction of JFK ballistics test, Paul on the scientific understanding of mystical, psychic, and occult experiences, Marlowe on a Gemini-1 mission UFO cover-up (?!) and/or how scammers victimize seniors, Pete on the Scientific Method and me on the basics of Modern Skepticism.
Check it out.

Expelled Exposed

The National Center for Science Education has put up a website, ExpelledExposed.com, to respond to the dishonest intelligent design movie featuring Ben Stein, Expelled. The current content is links to news coverage and reviews of the movie, but I expect the site will become more interesting when the movie is actually released on April 18.

The Wire's War on the Drug War

The writers of perhaps the best show on television, The Wire, have published an opinion piece in Time magazine in which they advocate that jurors vote to acquit any drug case defendant, and state that they will do so:

If asked to serve on a jury deliberating a violation of state or federal drug laws, we will vote to acquit, regardless of the evidence presented. Save for a prosecution in which acts of violence or intended violence are alleged, we will — to borrow Justice Harry Blackmun's manifesto against the death penalty — no longer tinker with the machinery of the drug war. No longer can we collaborate with a government that uses nonviolent drug offenses to fill prisons with its poorest, most damaged and most desperate citizens.

Jury nullification is American dissent, as old and as heralded as the 1735 trial of John Peter Zenger, who was acquitted of seditious libel against the royal governor of New York, and absent a government capable of repairing injustices, it is legitimate protest. If some few episodes of a television entertainment have caused others to reflect on the war zones we have created in our cities and the human beings stranded there, we ask that those people might also consider their conscience. And when the lawyers or the judge or your fellow jurors seek explanation, think for a moment on Bubbles or Bodie or Wallace. And remember that the lives being held in the balance aren't fictional.

I agree with them. (And if you want to know how government and other institutions in the real world actually work--or fail to do so--The Wire offers a good education, perhaps approached only by a completely different kind of show, the British comedy Yes, Minister.)
