"While there is no precise count, some experts believe New York is home to as many as 800 languages - far more than the 176 spoken by students in the city's public schools or the 138 that residents of Queens, New York's most diverse borough, listed on their 2000 census forms.\n\n"It is the capital of language density in the world," said Daniel Kaufman, an adjunct professor of linguistics at the Graduate Center of the City University of New York. "We're sitting in an endangerment hot spot where we are surrounded by languages that are not going to be around even in 20 or 30 years." "

"Howard Rhiengold, quoting Ernest Hemingway from 1954: "Every man should have a built-in automatic crap detector operating inside him." Have twenty minutes to spare? Even better, have twenty minutes to spare at a staff meeting? Which this video with your staff. Read the accompanying blog post. Talk about the literacies that we need to be helping students in our classrooms to develop."

"Will you have a better life if you graduate from an elite school? Students and their parents think the answer is yes, and competition for slots at top-ranked (and costly) schools seems higher than ever. Having a big name college on your resume can impress employers, friends and the opposite sex. The Times columnist Gail Collins says this national fixation makes little sense. "We can do a great service to the youth and parents of America by telling them to stop obsessing about choosing a college," she wrote recently in The Conversation blog. "Kids, you do not need to go to a school with a name that impresses your friends. Go to a school you can afford." If enough people took her advice, the spell might be broken. In the meantime, what should sensible and ambitious students keep in mind about where they go to school?"

"Here's a little ditty that catalogs and musically explains a useful list of cognitive biases uncovered by behavioral psychologists. It was created by Bradley Wray, a high school teacher in Maryland, as a study aid for students preparing for their AP Psychology exam. How are you biased? Let Bradley Wray count the ways."

I think I've linked this one already, but it's good enough to list twice!

"UPDATE: Fox News senior vice president for news Michael Clemente has responded to the study which found that his network's viewers are more misinformed about American political issues than any other channel. In a statement to the New York Times' Brian Stelter, Clemente disparaged the University of Maryland, where the study was done. "The latest Princeton Review ranked the University of Maryland among the top schools for having 'Students Who Study The Least' and being the 'Best Party School' - given these fine academic distinctions, we'll regard the study with the same level of veracity it was 'researched' with," Clemente said."

The Fox News VP responds to the study of FoxNews viewers misinformation status by making a textbook ad hominem on the university making the study, University of Maryland.

"AS hundreds of thousands of students rush to fill out college applications to meet end-of-the-year deadlines, it might be worth asking them: Is where you spend the next four years of your life that important? Harvard can give you advantages, but not everything. The sluggish economy and rising costs of college have only intensified questions about whether expensive, prestigious colleges make any difference. Do their graduates make more money? Get into better professional programs? Make better connections? And are they more satisfied with their lives, or at least with their work?"

"The 21-year-old woman was carefully trained not to flirt with anyone who came into the laboratory over the course of several months. She kept eye contact and conversation to a minimum. She never used makeup or perfume, kept her hair in a simple ponytail, and always wore jeans and a plain T-shirt. Each of the young men thought she was simply a fellow student at Florida State University participating in the experiment, which ostensibly consisted of her and the man assembling a puzzle of Lego blocks. But the real experiment came later, when each man rated her attractiveness. Previous research had shown that a woman at the fertile stage of her menstrual cycle seems more attractive, and that same effect was observed here - but only when this woman was rated by a man who wasn't already involved with someone else. The other guys, the ones in romantic relationships, rated her as significantly less attractive when she was at the peak stage of fertility, presumably because at some level they sensed she then posed the greatest threat to their long-term relationships. To avoid being enticed to stray, they apparently told themselves she wasn't all that hot anyway. This experiment was part of a new trend in evolutionary psychology to study "relationship maintenance." Earlier research emphasized how evolution primed us to meet and mate: how men and women choose partners by looking for cues like facial symmetry, body shape, social status and resources. "

"When high school students in Shanghai crack their history textbooks this fall they may be in for a surprise. The new standard world history text drops wars, dynasties and Communist revolutions in favor of colorful tutorials on economics, technology, social customs and globalization. Socialism has been reduced to a single, short chapter in the senior high school history course. Chinese Communism before the economic reform that began in 1979 is covered in a sentence. The text mentions Mao only once - in a chapter on etiquette. Nearly overnight the country's most prosperous schools have shelved the Marxist template that had dominated standard history texts since the 1950's. The changes passed high-level scrutiny, the authors say, and are part of a broader effort to promote a more stable, less violent view of Chinese history that serves today's economic and political goals."

"And this is how the Civil War comes to life for a roomful of fourth-graders in Northern Virginia, 150 years after the nation's deadliest armed conflict began. Agner's reenactment of the landmark naval Battle of Hampton Roads - a tactile lesson the vet­eran teacher dreamed up this year - drew her Fairfax County class into a chapter of American history that has long provoked education debate. The war's sesquicentennial, starting Tuesday with the anniversary of the attack on Fort Sumter in South Carolina, provides a "teachable moment" for schools everywhere. But how and when students learn about slavery and secession, blue and gray, Ulysses S. Grant and Robert E. Lee, Bull Run (or Manassas) and Appomattox varies enormously from state to state, school to school and even teacher to teacher. This year, Virginia learned anew the sensitivity of Civil War education when the state Board of Education withdrew approval of a fourth-grade textbook - "Our Virginia: Past and Present" - that asserted thousands of African Americans fought for the South. Most historians reject that claim. Last year, the Texas State Board of Education voted to require eighth-graders to study the inaugural address of Confederate President Jefferson Davis alongside President Abraham Lincoln's first and second inaugurals and his Gettysburg Address. That was one of many controversial revisions to Texas standards. Jeremy A. Stern, a historian who reviewed state academic standards this year for the Thomas B. Fordham Institute, said differences in the timing and scope of Civil War education across the United States are dramatic. Often, he said, the war is not taught systematically until middle school. "

"It was once a staple of public school cafeterias that blended the indulgent and the nutritious, satisfying parents and children both. But chocolate milk is uncontroversial no more. Dozens of districts have demanded reformulations. Others have banned it outright. At the center of these battles are complex public health calculations: Is it better to remove sugary chocolate flavorings at the risk that many students will skip milk altogether, missing out on crucial calcium and Vitamin D? Or should schools instead make tweaks - less fat, different sweeteners, fewer calories - that might salvage the benefits while minimizing the downside?"

In this edition I would like to explain why hot water freezes faster than cold water, when put into the freezer. It is a very counter-intuitive observation, it's a paradox. This is called the Mpemba Effect. The effect is named according to Tanzanian high-school student Erasto B. Mpemba who re-discovered the effect while making ice cream back in 1963. The Mpemba Effect is a nice example of how the change of one variable, the temperature, can have unexpected side effects. Most people assume that the difference between a hot glass of water and a cold glass of water is only the temperature. But this is not the case. Just by heating the water we are introducing a range of other variables that have an unexpected effect on the outcome.

"BUSINESSES in nearly every industry were caught off guard by the Great Recession. Few leaders in business - or government, for that matter - seem to have even considered the possibility that an economic downturn of this magnitude could happen. "

Parenting sites indicate many New York City parents want caregivers to teach their children a language.

Some interesting questions as to whether parents can "know" it's a good thing or a bad thing to have their children learn a second language. There are clearly cognitive and social costs and benefits that must be weighed.

"Should more laws be written to deal specifically with cyberbullying? If a victim commits suicide, should that factor into a decision to prosecute the accused bullies?"

"IF there is ever a class in how to remain calm while trapped beneath $250,000 in loans, Michael Wallerstein ought to teach it. Here he is, sitting one afternoon at a restaurant on the Upper East Side of Manhattan, a tall, sandy-haired, 27-year-old radiating a kind of surfer-dude serenity. His secret, if that's the right word, is to pretty much ignore all the calls and letters that he receives every day from the dozen or so creditors now hounding him for cash. "And I don't open the e-mail alerts with my credit score," he adds. "I can't look at my credit score any more." Mr. Wallerstein, who can't afford to pay down interest and thus watches the outstanding loan balance grow, is in roughly the same financial hell as people who bought more home than they could afford during the real estate boom. But creditors can't foreclose on him because he didn't spend the money on a house. "
