And then there was this... in a report published in the NY Times. It's about child education and the gaps between rich/poor and black/white. This small section is long, but just a snippet of a boring article, so please read it all!
(excerpted because it's long, full article here)
In thinking of the concept "no child left behind"... Why not just concentrate on correcting the academic disadvantages of poor people? Solve those, and the black-white gap will solve itself... Right?
"There had, in fact, been evidence for a long time that poor children fell behind rich and middle-class children early, and stayed behind. But researchers had been unable to isolate the reasons for the divergence. Did rich parents have better genes? Did they value education more? Was it that rich parents bought more books and educational toys for their children? Was it because they were more likely to stay married than poor parents? Or was it that rich children ate more nutritious food? Moved less often? Watched less TV? Got more sleep? Without being able to identify the important factors and eliminate the irrelevant ones, there was no way even to begin to find a strategy to shrink the gap.
Researchers began peering deep into American homes, studying up close the interactions between parents and children. The first scholars to emerge with a specific culprit in hand were Betty Hart and Todd R. Risley, child psychologists at the University of Kansas, who in 1995 published the results of an intensive research project on language acquisition. Ten years earlier, they recruited 42 families with newborn children in Kansas City, and for the following three years they visited each family once a month, recording absolutely everything that occurred between the child and the parent or parents. The researchers then transcribed each encounter and analyzed each child?s language development and each parent's communication style. They found, first, that vocabulary growth differed sharply by class and that the gap between the classes opened early. By age 3, children whose parents were professionals had vocabularies of about 1,100 words, and children whose parents were on welfare had vocabularies of about 525 words. The children's I.Q.'s correlated closely to their vocabularies. The average I.Q. among the professional children was 117, and the welfare children had an average I.Q. of 79.
When Hart and Risley then addressed the question of just what caused those variations, the answer they arrived at was startling. By comparing the vocabulary scores with their observations of each child's home life, they were able to conclude that the size of each child's vocabulary correlated most closely to one simple factor: the number of words the parents spoke to the child. That varied greatly across the homes they visited, and again, it varied by class. In the professional homes, parents directed an average of 487 utterances anything from a one-word command to a full soliloquy to their children each hour. In welfare homes, the children heard 178 utterances per hour.
What's more, the kinds of words and statements that children heard varied by class. The most basic difference was in the number of discouragements a child heard, prohibitions and words of disapproval compared with the number of encouragements, or words of praise and approval. By age 3, the average child of a professional heard about 500,000 encouragements and 80,000 discouragements. For the welfare children, the situation was reversed: they heard, on average, about 75,000 encouragements and 200,000 discouragements. Hart and Risley found that as the number of words a child heard increased, the complexity of that language increased as well. As conversation moved beyond simple instructions, it blossomed into discussions of the past and future, of feelings, of abstractions, of the way one thing causes another, all of which stimulated intellectual development.
Hart and Risley showed that language exposure in early childhood correlated strongly with I.Q. and academic success later on in a child's life. Hearing fewer words, and a lot of prohibitions and discouragements, had a negative effect on I.Q.; hearing lots of words, and more affirmations and complex sentences, had a positive effect on I.Q. The professional parents were giving their children an advantage with every word they spoke, and the advantage just kept building up.
In the years since Hart and Risley published their findings, social scientists have examined other elements of the parent-child relationship, and while their methods have varied, their conclusions all point to big class differences in children's intellectual growth. Jeanne Brooks-Gunn, a professor at Teachers College, has overseen hundreds of interviews of parents and collected thousands of hours of videotape of parents and children, and she and her research team have graded each one on a variety of scales. Their conclusion: Children from more well-off homes tend to experience parental attitudes that are more sensitive, more encouraging, less intrusive and less detached all of which, they found, serves to increase I.Q. and school-readiness. They analyzed the data to see if there was something else going on in middle-class homes that could account for the advantage but found that while wealth does matter, child-rearing style matters more.
Martha Farah, a researcher at the University of Pennsylvania, has built on Brooks-Gunn's work, using the tools of neuroscience to calculate exactly which skills poorer children lack and which parental behaviors affect the development of those skills. She has found, for instance, that the parental nurturance that middle-class parents, on average, are more likely to provide stimulates the brain's medial temporal lobe, which in turn aids the development of memory skills.
Another researcher, an anthropologist named Annette Lareau, has investigated the same question from a cultural perspective. Over the course of several years, Lareau and her research assistants observed a variety of families from different class backgrounds, basically moving in to each home for three weeks of intensive scrutiny. Lareau found that the middle-class families she studied all followed a similar strategy, which she labeled concerted cultivation. The parents in these families engaged their children in conversations as equals, treating them like apprentice adults and encouraging them to ask questions, challenge assumptions and negotiate rules. They planned and scheduled countless activities to enhance their children's development: piano lessons, soccer games, trips to the museum.
The working-class and poor families Lareau studied did things differently. In fact, they raised their children the way most parents, even middle-class parents, did a generation or two ago. They allowed their children much more freedom to fill in their afternoons and weekends as they chose playing outside with cousins, inventing games, riding bikes with friends but much less freedom to talk back, question authority or haggle over rules and consequences. Children were instructed to defer to adults and treat them with respect. This strategy Lareau named accomplishment of natural growth.
In her book Unequal Childhoods, published in 2003, Lareau described the costs and benefits of each approach and concluded that the natural-growth method had many advantages. Concerted cultivation, she wrote, places intense labor demands on busy parents. ... Middle-class children argue with their parents, complain about their parents' incompetence and disparage parents decisions. Working-class and poor children, by contrast, learn how to be members of informal peer groups. They learn how to manage their own time. They learn how to strategize. But outside the family unit, Lareau wrote, the advantages of natural growth disappear. In public life, the qualities that middle-class children develop are consistently valued over the ones that poor and working-class children develop. Middle-class children become used to adults taking their concerns seriously, and so they grow up with a sense of entitlement, which gives them a confidence, in the classroom and elsewhere, that less-wealthy children lack. The cultural differences translate into a distinct advantage for middle-class children in school, on standardized achievement tests and, later in life, in the workplace.
Taken together, the conclusions of these researchers can be a little unsettling. Their work seems to reduce a child's upbringing, which to a parent can feel something like magic, to a simple algorithm: give a child X, and you get Y. Their work also suggests that the disadvantages that poverty imposes on children aren't primarily about material goods. True, every poor child would benefit from having more books in his home and more nutritious food to eat (and money certainly makes it easier to carry out a program of concerted cultivation). But the real advantages that middle-class children gain come from more elusive processes: the language that their parents use, the attitudes toward life that they convey. However you measure child-rearing, middle-class parents tend to do it differently than poor parents and the path they follow in turn tends to give their children an array of advantages. As Lareau points out, kids from poor families might be nicer, they might be happier, they might be more polite but in countless ways, the manner in which they are raised puts them at a disadvantage in the measures that count in contemporary American society."
