Listen to your Kindergarten Teachers

Early this year, Mr. Chetty and five other researchers set out to fill this void. They examined the life paths of almost 12,000 children who had been part of a well-known education experiment in Tennessee in the 1980s. The children are now about 30, well started on their adult lives.

On Tuesday, Mr. Chetty presented the findings — not yet peer-reviewed — at an academic conference in Cambridge, Mass. They’re fairly explosive.

Just as in other studies, the Tennessee experiment found that some teachers were able to help students learn vastly more than other teachers. And just as in other studies, the effect largely disappeared by junior high, based on test scores. Yet when Mr. Chetty and his colleagues took another look at the students in adulthood, they discovered that the legacy of kindergarten had re-emerged.

Students who had learned much more in kindergarten were more likely to go to college than students with otherwise similar backgrounds. Students who learned more were also less likely to become single parents. As adults, they were more likely to be saving for retirement. Perhaps most striking, they were earning more.

All else equal, they were making about an extra $100 a year at age 27 for every percentile they had moved up the test-score distribution over the course of kindergarten. A student who went from average to the 60th percentile — a typical jump for a 5-year-old with a good teacher — could expect to make about $1,000 more a year at age 27 than a student who remained at the average. Over time, the effect seems to grow, too....

But the anti-education case usually relies on a combination of anecdotes and selective facts. In truth, the gap between the pay of college graduates and everyone else grew to a record last year, according to the Labor Department, and unemployment has risen far more for the less educated.

This is not simply because smart people — people who would do well no matter what — tend to graduate from college. Education itself can make a difference. A long line of economic research, by Julie Berry Cullen, James Heckman, Philip Oreopoulos and many others, has found as much. The study by Mr. Chetty and his colleagues is the latest piece of evidence....

Mr. Chetty and his colleagues — one of whom, Emmanuel Saez, recently won the prize for the top research economist under the age of 40 — estimate that a standout kindergarten teacher is worth about $320,000 a year. That’s the present value of the additional money that a full class of students can expect to earn over their careers. This estimate doesn’t take into account social gains, like better health and less crime.

The Hacker Role Model

New Yorker profile of WikiLeaks Julian Assange;
Assange was born in 1971, in the city of Townsville, on Australia’s northeastern coast, but it is probably more accurate to say that he was born into a blur of domestic locomotion. Shortly after his first birthday, his mother—I will call her Claire—married a theatre director, and the two collaborated on small productions. They moved often, living near Byron Bay, a beachfront community in New South Wales, and on Magnetic Island, a tiny pile of rock that Captain Cook believed had magnetic properties that distorted his compass readings. They were tough-minded nonconformists. (At seventeen, Claire had burned her schoolbooks and left home on a motorcycle.) Their house on Magnetic Island burned to the ground, and rifle cartridges that Claire had kept for shooting snakes exploded like fireworks. “Most of this period of my childhood was pretty Tom Sawyer,” Assange told me. “I had my own horse. I built my own raft. I went fishing. I was going down mine shafts and tunnels.”

Assange’s mother believed that formal education would inculcate an unhealthy respect for authority in her children and dampen their will to learn. “I didn’t want their spirits broken,” she told me. In any event, the family had moved thirty-seven times by the time Assange was fourteen, making consistent education impossible. He was homeschooled, sometimes, and he took correspondence classes and studied informally with university professors. But mostly he read on his own, voraciously. He was drawn to science. “I spent a lot of time in libraries going from one thing to another, looking closely at the books I found in citations, and followed that trail,” he recalled. He absorbed a large vocabulary, but only later did he learn how to pronounce all the words that he learned...

While on the run, Claire rented a house across the street from an electronics shop. Assange would go there to write programs on a Commodore 64, until Claire bought it for him, moving to a cheaper place to raise the money. He was soon able to crack into well-known programs, where he found hidden messages left by their creators. “The austerity of one’s interaction with a computer is something that appealed to me,” he said. “It is like chess—chess is very austere, in that you don’t have many rules, there is no randomness, and the problem is very hard.” Assange embraced life as an outsider. He later wrote of himself and a teen-age friend, “We were bright sensitive kids who didn’t fit into the dominant subculture and fiercely castigated those who did as irredeemable boneheads.”

When Assange turned sixteen, he got a modem, and his computer was transformed into a portal. Web sites did not exist yet—this was 1987—but computer networks and telecom systems were sufficiently linked to form a hidden electronic landscape that teen-agers with the requisite technical savvy could traverse. Assange called himself Mendax—from Horace’s splendide mendax, or “nobly untruthful”—and he established a reputation as a sophisticated programmer who could break into the most secure networks. He joined with two hackers to form a group that became known as the International Subversives, and they broke into computer systems in Europe and North America, including networks belonging to the U.S. Department of Defense and to the Los Alamos National Laboratory. In a book called “Underground,” which he collaborated on with a writer named Suelette Dreyfus, he outlined the hacker subculture’s early Golden Rules: “Don’t damage computer systems you break into (including crashing them); don’t change the information in those systems (except for altering logs to cover your tracks); and share information.”

The Right Role Models for Children

Some sports personalities are good role models.

We recommend the following book-
Pele, King of Soccer/Pele, El rey del futbol

Illustrated by Rudy Gutierrez

School of Pretending

An interesting essay about high school education;

In my high school French class we were supposed to read Hugo's Les Miserables. I don't think any of us knew French well enough to make our way through this enormous book. Like the rest of the class, I just skimmed the Cliff's Notes. When we were given a test on the book, I noticed that the questions sounded odd. They were full of long words that our teacher wouldn't have used. Where had these questions come from? From the Cliff's Notes, it turned out. The teacher was using them too. We were all just pretending.

The odds are against human babies!

Interesting article;

In the fable, the tortoise wins the race because the hare takes a nap. But, if anything, human infants nap even more than kittens! And unlike the noble tortoise, babies are helpless, and more to the point, hopeless. They could not learn the basic skills necessary to their independent survival even if they tried. How do human babies manage to turn things around in the end?

In a recent article in Current Directions in Psychological Science, Sharon Thompson-Schill, Michael Ramscar and Evangelia Chrysikou make the case that this very helplessness is what allows human babies to advance far beyond other animals. They propose that our delayed cortical development is precisely what enables us to acquire the cultural building blocks, such as language, that make up the foundations of human achievement. Indeed, the trio makes clear that our early vulnerability is an evolutionary “engineering trade-off,” much like the human larynx—which, while it facilitates the intricate productions of human speech, is actually quite a precarious adaptation for anyone trying to swallow safely. In the same way, they suggest, our ability to learn language comes at the price of an extended period of cognitive immaturity.

This claim hinges on a peculiar and unique feature of our cognitive architecture: the stunningly slow development of the prefrontal cortex (PFC). While other animals’ brain regions development in synchrony, in humans, the development of the PFC lags far behind that of other areas. The PFC is the swath of gray matter that makes up the anterior frontal lobes, and functionally, it appears to be heavily implicated in a wide-range of sophisticated planning and attention driven behaviors. Indeed, it is often referred to as the “control” center of the brain. One of its main functions appears to be that of selectively filtering information from the senses, allowing us to attend to specific actions, goals, or tasks. For this reason, “cognitive control” tasks are thought to be one of the best assessors of PFC function and maturity, and they are tests that young children reliably, and ignominiously, fail.

Parents overstate their influence on children

Some children are just born to be bad?;

It goes against the grain not just because it seems like such a grim and pessimistic judgment, but because it violates a prevailing social belief that people have a nearly limitless potential for change and self-improvement. After all, we are the culture of Baby Einstein, the video product that promised — and spectacularly failed — to make geniuses of all our infants.

Not everyone is going to turn out to be brilliant — any more than everyone will turn out nice and loving. And that is not necessarily because of parental failure or an impoverished environment. It is because everyday character traits, like all human behavior, have hard-wired and genetic components that cannot be molded entirely by the best environment, let alone the best psychotherapists.

“The central pitch of any child psychiatrist now is that the illness is often in the child and that the family responses may aggravate the scene but not wholly create it,” said my colleague Dr. Theodore Shapiro, a child psychiatrist at Weill Cornell Medical College. “The era of ‘there are no bad children, only bad parents’ is gone.”

I recall one patient who told me that she had given up trying to have a relationship with her 24-year-old daughter, whose relentless criticism she could no longer bear. “I still love and miss her,” she said sadly. “But I really don’t like her.”

For better or worse, parents have limited power to influence their children. That is why they should not be so fast to take all the blame — or credit — for everything that their children become.

Finding the right role models for your children

Ms. Cyrus’s appeal among those age 13 to 17 has dropped, too, according to E-Poll Market Research, a brand and celebrity research firm. Of those surveyed online recently, only 24 percent said they liked or liked her a lot, compared with 45 percent in 2008. Those who track preteens are noticing the shift. Tina Wells, a market research executive who consults with Fortune 500 companies, said Ms. Cyrus ranked No. 7 in April on its list of celebrities considered cool by children 8 to 12 years old. Two years ago she was No. 1....

It is tricky for any teenage star to navigate the path to adulthood. (Britney Spears? Lindsay Lohan?) But Ms. Cyrus, it seems, is alienating her fans faster than she is gaining new ones. Partly to blame is last year’s pole dance at the Teen Choice Awards, and the recent video posted on TMZ of her giving a lap dance to a 44-year-old film director.

For some mothers of Ms. Cyrus’s fans, her wrenching transition from teen idol to sexual icon has become a teachable moment.

“I’m just impressed with kids picking up on the change and saying it’s not that interesting and they don’t relate,” said Megan Calhoun of Ross, Calif., the founder of TwitterMoms, a blog for mothers that has 26,000 members. Some have expressed dismay at the shift in Ms. Cyrus’s persona. “It’s almost as if these young stars don’t realize it is a turnoff,” Ms. Calhoun said.

Some parents chalk up her behavior to teenage angst. “It doesn’t surprise me what she is going through,” said Wendy Ellis, a mother of two from Odenton, Md. “The raging hormones. She is testing the limits of the box and what is appropriate.”

Please Help Avoid Misdiagnosing Development Disorders


It is estimated that one in six children suffer from developmental disorders, including mental retardation, autism spectrum disorders, learning disorders, attentional disorders, genetic disorders, sleep disorders.  However, despite the fact that all these disorders originate in the brain, most of them are diagnosed solely by looking at behavioural symptoms without ever looking at the brain!  That is, they are diagnosed behaviourally rather than neurologically.  This often results in an incomplete or inaccurate diagnosis....

Almost 50% of the children previously diagnosed with autism are found to be suffering from some degree of brain seizure activity that is undetectable to the eye.  In some cases, these seizures are the cause of the child's autism-like symptoms.  In other cases, these seizures are not causal, but comorbid (coexistent) to autism and are exacerbating the child's symptoms.  And in a few cases, the seizures are mild and possibly unrelated to, or a consequence of, the child's symptoms.  In the cases where these seizures are the cause of the symptoms, once the seizures have been detected and treated, the level and speed of recovery in the children has been remarkable.

Making Stories from Pictures


Todays Challenge: Use one or more of the Norman Rockwell paintings, depicted in the images below, to create a new short story or poem:


A profile of Rockwell in NYT;
To me the most important part of Rockwell’s work is that it illustrates compassion and caring about other people,” the filmmaker George Lucas, who lives in Marin County, Calif., said recently. “You could almost say he was a Buddhist painter.”

Steven Spielberg, speaking from Los Angeles, had similar praise. “Anything for Norman,” he said, when asked to discuss his work. “He was always on my mind because I had a great deal of respect for how he could tell stories in a single frozen image. Entire stories.”...

Mr. Lucas and Mr. Spielberg trace their Rockwell love to their childhoods, when they pored over the covers of The Saturday Evening Post, a weekly magazine (and misnomer) that arrived in mailboxes on Thursdays. They started collecting his work before it was validated by the art world. According to his records Mr. Lucas bought his first Rockwell, a calendar illustration, on May 16, 1980. A year and a half later Mr. Spielberg bought his first Rockwell, a stirring painting that was commissioned in 1923 as an advertisement for Underwood typewriters. It shows a young writer hunched at his cluttered desk as Daniel Boone floats above on puffy clouds, a figure of glamorous virility who provides the boy with both a subject for his literary efforts and a painful reminder of his limitations.

“I hung the painting over my desk,” Mr. Spielberg recalled. “It was my deblocker. Whenever I hit a wall or couldn’t figure out where a story was going, I just looked up at that painting.”

Memo to Self via Book Covers

"One interesting practical suggestion is to keep a "gratitude journal," in which you routinely list experiences and circumstances for which you are grateful."- Ben Bernanke

Thanks! How Practicing Gratitude Can Make You Happier, by Robert A. Emmons

Keep a Gratitude Journal- some reasons:

Spirituality: Those who regularly attend religious services and engage in religious activities such as prayer reading religious material score are more likely to be grateful. Grateful people are more likely to acknowledge a belief in the interconnectedness of all life and a commitment to and responsibility to others (McCullough et. al., 2002). Gratitude does not require religious faith, but faith enhances the ability to be grateful.

A related benefit was observed in the realm of personal goal attainment: Participants who kept gratitude lists were more likely to have made progress toward important personal goals (academic, interpersonal and health-based) over a two-month period compared to subjects in the other experimental conditions.

The Best Parents Have Patience

How to Become a Patient Parent

Stubborn Pre-schoolers;
Three year olds: first, the sympathy. My grandfather always said about my brother at this age that he could wear out an iron horse and aggravate a fly to death.

I have a stubborn kid, too, still stubborn at 7 although better than he was at 3. Your daughter does sound like an extra handful though. First of all, see if you can get a book (from your local library) called "Your Three Year Old." This is part of a series written some years ago by a couple of psychologists and I have found it very useful in dealing with the psychological changes that happen as children grow older.

In the case of my son I am a single parent with no other support, so I really had to choose my battles to avoid getting totally flattened. If my son wanted to eat cereal every night for dinner for two months, that's what he ate. When we got into a fight in the morning about getting dressed warmly enough, I took him outside to feel the cool air, then he was usually good about dressing warmly enough.

The only advice I can offer you is to try to give your daughter a choice as much as possible, but not an unlimited choice. And as much as possible you make her decide, in a timely manner. So when you are fixing her hair, ask her how many ponytails she wants. When it is time to get dressed (and don't, by the way, say "Time to get dressed.") ask her to choose between pants and a dress. For dinner, you might offer her what the family is eating, or give her one other easy to fix option, such as cereal, make her decide, then stick with it.
