George Schmidt has been writing in his brave tabloid, Substance, for some time about the growing influence of the military in the public schools of Chicago. Now the mainstream media is starting to notice, and with Congress lifting the cap on such programs, the urban military school offers an unprecedented opportunity for Washington to develop a steady stream of trained recruitment targets for continuing war plans and other follies of empire.
These new military schools are mostly black and brown, and poor, you understand. Who needs a draft when you can starve potential recruits into the Army? Last week 6,000 people showed up in Cleveland to apply for 300 Walmart jobs. And in Chicago, itself?
In Illinois recently, Masten said, 25,000 and 15,000 people applied at two Wal-Mart stores in the Chicago area, and neither of those is a large Supercenter.
CHICAGO (AFP) — Dozens of teens dressed in uniforms provided by the US Marines stand at attention in the gym of a Chicago public high school as a drill sergeant goes through a list of the day's do's and don'ts.
Bring your books to class. Come for extra help if you need it. And wear your uniform with pride.
"Young men, you think you can get a haircut and say I'm done for two or three weeks. WRONG," Sgt. Major Thomas Smith Jr. intones.
"Young ladies. There's been no problem with your uniforms but there is a problem with your ties. Again, I will go through it again. Wear your ties when you come to my class."
One in 10 public high school students in Chicago wears a military uniform to school and takes classes -- including how to shoot a gun properly -- from retired veterans.
That number is expected to rise as junior military reserve programs expand across the country now that a congressional cap of 3,500 units has been lifted from the nearly century-old scheme.
Proponents of the junior reserve programs say they provide stability and a sense of purpose for troubled youth and help to instill values such as leadership and responsibility.
But opponents say the programs divert critical resources from crumbling public schools and lead to a militarization of US society. . . .
This semester I have been teaching an online course: “Organizing for Social Action in Urban Communities.” I have posted the draft lectures for the entire course here, under a Creative Commons license, so that readers are free to use them they wish.
As I note in the “Overview”:
The course is NOT intended to teach students how to be a community organizer. They don't learn how to work with the media, or run a house meeting, nor other practical skills like that. Instead the course is designed to help students learn how to THINK like an organizer.
The actual lectures represent a first draft effort to figure out how to teach "community organizing" to students for whom this is really an alien perspective. The overall structure of the course has evolved in more than five years of teaching in a face-to-face format.
My only request is that if people do read and use this material they send me comments about their impressions and experiences. You are free to post comments to this announcement post. The course is a work in progress, and I will be updating it periodically with newer drafts.
In the last few weeks, Eduwonkette has been writing her blog entries in themes. Last week was "Test Score Spin Doctors," focused on the distortions of NYC's Board of Education. This week is Signithia Fordham and John Ogbu's "Acting White" Hypothesis. Because Ogbu's arguments about culture and education, and the 1987 article Fordham and he cowrote, are provocative and the most interesting academic equivalents of the culture argument on the achievement gap, I strongly encourage folks in social foundations to read these blog entries. I'll probably add some commentary towards the end of the week here.
A second issue is Eduwonkette's choice of a weekly theme. I don't know if this is the start of a broader pattern, but if so, it's an interesting (and coherent) way to organize a blog. It's not the only education blog to have tried this (Edspresso had occasional weeklong debates for a year, from May 2006 through May 2007), but for an individual blogger, that's a form of blogging moxie. Most of us are more anarchic than that.
The Problem With Youth Activism
The institutionalization of activism on college campuses is a key culprit in the absence of visible youth movements in this country.
Many social and cultural histories have examined changes in American attitudes towards gender, race, class, sexuality and the body, often with attention to prescriptive writings advising parents on how to raise children who might approximate these ideals in body and mind. Yet few historians consider how such many of these ideas were put into practice through the physical manipulation of space and the material construction of social realities.
Even infants can tell the difference between naughty and nice playmates, and know which to choose, a new study finds.
If the entire human species were a single individual, that person would long ago have been declared mad. The insanity would not lie in the anger and darkness of the human mind—though it can be a black and raging place indeed. And it certainly wouldn't lie in the transcendent goodness of that mind—one so sublime, we fold it into a larger "soul." The madness would lie instead in the fact that both of those qualities, the savage and the splendid, can exist in one creature, one person, often in one instant.
The deepest foundation on which morality is built is the phenomenon of empathy, the understanding that what hurts me would feel the same way to you. And human ego notwithstanding, it's a quality other species share. While it's impossible to directly measure empathy in animals, in humans it's another matter. Here are some of the dilemmas used to study human morality. Take this quiz to see how you compare to other TIME.com readers. Then read how scientists are using these dilemmas to study morality.
Voting By Altruists: Some Electoral Implications of Civic Virtue
The present analysis demonstrates that civic virtue can play a complementary role by increasing support for such [redistributive] programs and by increasing the efficiency of public services. Whether altruistic voters are common or not, the analysis of this paper suggests that the altruistic component of civic virtue can play a significant role in making democratic societies more attractive places in which to live. Even a relatively small number of civil altruists can make a difference.

Old-fashioned retro toys, such as red rubber balls, simple building blocks, clay and crayons, that don't cost much are usually much healthier for children than the electronic educational toys that have fancier boxes, according to developmental psychologists.

Screening tests widely used to identify children with reading problems are being misapplied, landing students in the wrong instructional level and delaying treatment for their true difficulties, says new research. The researchers find that oral reading tests fail to distinguish between children who can't understand words on a page and those who have language problems that make it difficult to prove their reading competence verbally. Children with these so-called "word-finding" difficulties can't manage to say out loud what they read on the page. |
A study finds student use of social network sites such as Facebook and MySpace can be predicted by race, ethnicity and parent education, challenging popular notions of the democratic nature of online communication. The study finds less intermingling of users from diverse backgrounds on these sites than previously believed. White students prefer Facebook; Hispanics prefer MySpace. Asian and Asian-American students use less popular sites including Xanga more than other groups. |

It’s a general belief that the circuitry of young brains has robust flexibility but eventually gets "hard-wired" in adulthood. As Johns Hopkins researchers and their colleagues report in the Nov. 8 issue of Neuron, however, adult neurons aren’t quite as rigidly glued in place as we suspect.
The Wisconsin Policy Research Institute's recent study documenting that school choice "isn't a powerful tool for driving educational improvement in Milwaukee Public Schools" is a welcome finding from a conservative think tank that has long championed publicly funded, private school choice.

Educators and psychologists have long feared that children entering school with behavior problems were doomed to fall behind in the upper grades. But two new studies suggest that those fears are exaggerated.
"Why do people think artists are special? It's just another job." So said Andy Warhol, one of the greatest artists of the past century. He zeroed in on a myth that lives on in the art world and academia alike. Dazzled by genius, too many people assume that artists are born with mystical abilities unknowable to the rest of us. In fact, many innovations spring not from their creators' innate talent, but from their years of accumulated knowledge. Keep that in mind when you head to an art museum, settle into your seat at a theater or open a new book. Sometimes what looks like creative genius is just regular old hard work.

Sometimes it's difficult for us to remember how we felt about a product. A new study reveals that when memory fails, consumers will use postpurchase actions as a proxy.

There is little substantive evidence that binge drinking while pregnant seriously harms the developing fetus, finds a new study. Consistently heavy drinking throughout pregnancy has been associated with birth defects and subsequent neurological problems. But it is not known what impact binge drinking, in the absence of regular heavy drinking, might have. And this drinking pattern is becoming increasingly common, particularly among women, say the authors. They suggest that further research is required, but in the meantime it might be wise to advise women to avoid binge drinking during pregnancy, just in case. |

It has long been assumed that consumers are good judges of affordability, but a new study reveals that how much you're willing to spend is influenced by whether you think about a larger pool of resources (such as your bank account) or a smaller pool (the cash in your wallet).

Rarely is it the case that highly influential individuals are responsible for bringing about shifts in public opinion. Instead, scientists find that it is the presence of large numbers of "easily influenced" people who bring about major shifts by influencing other easy-to-influence people. |
In youth with attention deficit hyperactivity disorder, the brain matures in a normal pattern but is delayed three years in some regions, on average, compared to youth without the disorder, MRI scans reveal. The delay in ADHD was most prominent in regions at the front of the brain's outer mantle important for thinking and attention. Both groups showed a similar back-to-front wave of brain maturation with different areas peaking in thickness at different times. |
A forthcoming study looks at how consumers anthropomorphize products, endowing a car or a pair of shoes with human characteristics and personalities.

New research into childhood prejudice suggests that loyalty and disloyalty play a more important role than previously thought in how children treat members of their own and other groups. A study into the 'black sheep effect,' shows that children treat disloyalty in their own group more harshly than disloyalty within different groups. |

I have been reading* a book recently in preparation of a book review for the Journal of Philosophy of Education. The book, by my good friend David Granger, is John Dewey, Robert Pirsig, and the Art of Living. While some of the book gets mired in somewhat arcane issues of interest primarily to scholars, it is an exceptionally well-written book, with some keen insights into the nature of nature, the arts, and education that might have broader appeal.
I've been paying particular attention to what the book has to say about the dispositions or attitudes of students who are "wholly" engaged in learning. John Dewey describes "aesthetic experience" as experiences with a special quality that marks them off as aesthetic; this special quality often involves some kind of "consummation" in which the various parts and aspects of a situation come together in a satisfying or at least memorable way. People involved in aesthetic experiences often exhibit certain attitudes or dispositions with regard to the experience. In Zen and the Art of Motorcycle Maintenance, Robert Pirsig illustrates these attitudes and dispositions in his description of a "high quality" mechanic at work on motorcycle maintenance. As I was reading Granger's summary of Pirsig's descriptions, I was struck by the similarities between the attitudes and dispositions of high quality mechanics and the Technology in Education students I have worked with who seem particularly engaged in and committed to the quality of what they are working on.
In our TIE program, we often assign our students with projects that require creation of some product such as a web site or hypermedia project. Our projects invariably involve a rubric spelling out the minimal requirements but also require the students to create something that can be used within their particular professional setting, such as their second grade classroom, high school English classes, or school- and district-wide professional development needs. These projects exemplify the kind of authentic tasks and situated inquiry that epitomize the best forms of engaged learning based on constructivist learning theories.
The projects also involve a situation often found in the process of creating art objects: an iterative interaction between a medium or media (the "material") and the plans or ideal ends (the "vision") of the artist. Motorcycle mechanics must pay particular attention to the machine sitting in front of them, and of the qualities and affordances of the materials with which parts and systems are constructed. TIE students must come to see the possibilities and limitations afforded by a particular piece of software or digital medium, and work creatively to figure out how to make their plans come to fruition. The back-and-forth between material and vision, or between medium and ideal, is intrinsic to any creative endeavor, and it requires at a minimum that the creator pay attention to the medium and how it responds to attempts to shape it (or make it run better, in the case of the mechanic).
Such attention requires certain attitudes and dispositions on the part of the creator, mechanic, or student. First and foremost, is a willingness to care about the quality of the product. Such a willingness implies also a a willingness or make mistakes, and to learn from those mistakes and push forward rather than being discouraged or dissuaded from the ideal end or ends being pursued. This implies an attitude toward the "self" of the creator/mechanic/student--an openness to personal or professional growth in which the present self doesn't "get in the way" of the emergence of a newer, more competent and creative new self.
What I'm saying is that even the most mundane creative endeavor requires a certain kind of "learning attitude" or set of character traits that involves openness to transformation or at least change in the person, as well as in the medium. Thus, even a "technology in education" student, to be successful in learning not only technical skills but curriculum design and development means a kind of moral or spiritual stance with regard to one's self. Students who come to the class expecting to maintain their old selves while "creating" technology projects will either produce mediocre work or will find themselves challenged in the course of their program. Such challenges are intrinsic to learning of all kinds, whether learning to care for someone, learning to maintain a motorcycle, or learning how to build curriculum webs.
In response to Dr. Horn's post...
Reducing the “achievement gap” to what goes on inside of schools has proven to be an effective way for policy makers to ignore all of the other “gaps” outside of America’s classrooms.
While researcher after researcher has shown that outside influences contribute to student performance and achievement, proponents of high-stakes, standardized reforms continue to press for more “rigor,” as if harder work alone will mitigate every outside factor influencing children’s lives.
Rather than focusing exclusively on the “achievement gap,” policy makers and educational reformers might consider policies that help reduce other “gaps” that exist within our country. Gaps that could be narrowed in order to improve the lives and schooling of all students include but are not limited to:
• The incarceration gap, where six times as many African Americans are behind bars compared to their white counterparts;
• The homeowner gap, where 72.7% of white Americans own their homes compared to 48.2% of African Americans;
• The healthcare gap, where 71.4% of white Americans are insured compared to 53.9% of African Americans;
• The earnings gap, where white Americans average over $20,000 more a year than African Americans;
• The poverty rate gap, where 8.7% of white Americans live at or below the poverty line while 24.7% of African Americans do so;
• The unemployment gap, where 5.7% of white Americans are unemployed while 13.2% of African Americans are without work;
• The happiness gap, where 72% of white youths say they are happy with life in general compared to 56% of their African American counterparts;
• The murder gap, where 49% of murder victims in the United States are African Americans, who make up 13% of the population.
Close one of these and I warrant the "achievement gap" shrinks.
Or, if I may be snarky for a moment...privatize public schools and hold our breath until the market closes these gaps for us...

For white philanthropists, the major appeal of the KIPP charter chain gang schools is the non-stop behavioral control system aimed at producing compliant worker bees who learn to internalize any real or potential shortcomings as evidence of individual weakness or failure. If things don't work out, then, as the KIPP brainwashers promise, then who is to blame? This is not a new pedagogical approach--it was used successfully at Hampton Institute in the late 19th Century to train a generation of black teachers like Booker T. Washington, who would become complicit in their own subjugation and that of their brothers and sisters.
For black parents, the KIPP appeal is the promise that for those who "work hard, be nice," there is a new world of opportunity waiting to embrace their efforts. Hope, however groundless, remains the only alternative to despair.
New studies by Pew and reported in WaPo show some disturbing realities that are troubling at least, even though they are likely to be ignored in the keep-on-the-sunny-side world of those who have been KIPP-notized.
A couple of clips here:
Nearly half of African Americans born to middle-income parents in the late 1960s plunged into poverty or near-poverty as adults, according to a new study -- a perplexing finding that analysts say highlights the fragile nature of middle-class life for many African Americans.
Overall, family incomes have risen for both blacks and whites over the past three decades. But in a society where the privileges of class and income most often perpetuate themselves from generation to generation, black Americans have had more difficulty than whites in transmitting those benefits to their children.
Forty-five percent of black children whose parents were solidly middle class in 1968 -- a stratum with a median income of $55,600 in inflation-adjusted dollars -- grew up to be among the lowest fifth of the nation's earners, with a median family income of $23,100. Only 16 percent of whites experienced similar downward mobility. At the same time, 48 percent of black children whose parents were in an economic bracket with a median family income of $41,700 sank into the lowest income group.
. . . .
Overall, family income of blacks in their 30s was $35,000, 58 percent that of comparable whites, a gap that did not surprise researchers. Startling them, however, was that so many blacks fell out of the middle class to the bottom of the income distribution in one generation.
Ronald B. Mincy, a Columbia University sociologist who has focused on the growing economic peril confronted by black men and who served as an adviser on the Pew project, said skeptical researchers repeatedly reviewed the findings before concluding they were statistically accurate.
"There is a lot of downward mobility among African Americans," Mincy said. "We don't have an explanation."
Pew hopes to develop some answers in future reports in its series on economic mobility. Reports scheduled to be released early next year will probe, among other things, the role of wealth and education in income mobility.
Mincy and others speculated that the increase in the number of single-parent black households, continued educational gaps between blacks and whites and even racial isolation that remains common for many middle-income African Americans could be factors.
"That's a stunner," said Orlando Patterson, a Harvard University sociologist, when told about the Pew finding. "These kids were middle class, but apparently their parents did not have the cultural capital and connections to pass along to them."
Another reason so many middle-class blacks appear to be downwardly mobile is likely the huge wealth gap separating white and black families of similar incomes. For every $10 of wealth a white person has, blacks have $1, studies have found.
"We already knew that downward mobility was much more likely for blacks," said Mary Pattillo, a Northwestern University sociologist who studies the black middle class. "But this is an even bigger percentage drop than I have seen elsewhere. That's very steep."
This is in response to a front-page Sunday NY Times article which I found maddeningly imprecise. The journalist confuses the notion of race so many times through the different perspectives that the average reader can only continue to assume that there is such a thing as a fixed and genetic race.
Let me, just because I can’t stand imprecision about this, make a few points. While I am not a geneticist or a physical anthropologist, there are enough fallacies to sink this article. At the heart of the confusion is that she uses two different notions of race seemingly interchangeably, when only one of them is accurate: the first (and correct) notion is that certain groups of people have certain geographic origins, what she correctly referred to as “continental groups.” Such groupings, over tens of thousands of years fostered, amongst other things, divergence of characteristics due to random mutations in isolated populations (if isolated can be used in the sense of continental isolation) and to the fact that these isolated populations most likely had slightly different genetic patterning already based on their divergent wanderings out of Africa. The second (incorrect) notion is that such groupings constitute a coherent, monolithic, and stable “race” such as Caucasians, Asians, etc. Thus when Amy Harmon begins the article by suggesting that DNA can explain the differences of distinct groups of human beings – e.g., the fact that some populations have lighter or darker skin; the fact that Asians sweat less; the fact that West Africans have different resistance to certain diseases – she is conflating the two ideas to suggest that genetic markers equals race. As she states, “genetic information is slipping out of the laboratory and into everyday life, carrying with it the inescapable message that people of different races have different DNA.” The rest of the article is then an attempt to deal with the (completely false problem) of how scientists and non-scientists have to then deal with explaining away what seems to lay-people as scientific proof for the genetic difference of races. The most volatile aspect of this is the tired issue of so-called linkages between race and IQ. See the Bell Curve Wars among the thousands of books, articles, web sites, etc for a refutation of this fallacious claim.
But if the journalist had not made the initial conflation, and had just stuck with the facts that different genes in peoples of different geographic origins had different outcomes (disease resistance, darker skin, etc.) all of this hand-wringing would have been moot. All genes are independent of each other. The only reason that we falsely believe that some genes are aligned (e.g., African-Americans have darker skin, fuller lips, curlier hair, etc.) is due to the long-term continental isolation of populations tens of thousand of years ago.
Harmon even quotes several scholars who point out the overwhelming influence of environment and the socially constructed nature of our racial classifications, but these ideas slide off of her just like they do for the student (cited at the end of the article) who now embraces her African-American heritage and goes to a Kwanzaa festival after finding 9% of her DNA is of that West African ancestry.
Let me be clear: of course people make judgments on racial features; of course there is still covert and overt racism even if no such thing as race exists (in a genetic sense); of course racial issues are still volatile and difficult to discuss. But the basic point is that race is not genetic. Certain characteristics are of course genetically based. But these are two very, very different points. And such sloppy reporting only perpetuates our inability as a society to address these complex matters.
Rates of PTSD are much higher in children and adolescents recruited from at-risk samples. The rates of PTSD in these at-risk children and adolescents vary from 3 to 100%. For example, studies have shown that as many as 100% of children who witness a parental homicide or sexual assault develop PTSD. Similarly, 90% of sexually abused children, 77% of children exposed to a school shooting, and 35% of urban youth exposed to community violence develop PTSD.
How Does PTSD Affect These Children?
In one study of children in foster care, 64% who had experienced sexual abuse had PTSD, and 42% who had experienced physical abuse fulfilled the PTSD criteria. Moreover, 18% of the children who were not abused also met PTSD criteria, presumably because they had witnessed violence. . . . .
In addition to the symptoms of numbing, hyperarousal, and recollections of the event that adults experience, children often become unable to participate in the normal developmental experiences of childhood, such as visiting friends and participating in after-school activities. In addition, the quality of schoolwork is likely to be significantly compromised. The compromised ability to participate in the normal developmental experiences of childhood has far-ranging impact, even when and if the initial underlying symptoms that are the basis for diagnosing PTSD are resolved.
Furthermore, a host of emotional and behavioral problems frequently arise as a result of PTSD and are not part of the criteria for categorical diagnosis. These include disruptive behavior disorders, eating disorders, sexual acting out, other risk-taking activities, depression, the full range of anxiety disorders, dissociation, mood lability, violence, and difficulty concentrating.
More Effects on Achievement and Young Brains:
This new understanding of the way childhood trauma affects memory and the brain has important implications for public health policy. One example would be the case of inner-city children who have witnessed violent crimes in their neighborhoods and families. If this kind of stress can cause damage to brain areas involved in learning and memory, it would put these children at a serious academic disadvantage in ways and for reasons that programs such as Head Start may be unable to address. Studies confirm this: in war-torn
Study of 113 Inner-City Children:
The author of the
By age seven, 74 percent of the children in the study had heard gunfire and 13 percent had witnessed a shooting or stabbing in their own home. 60 percent reported that they worry some or much of the time that they may get killed or die; 20 percent sometimes wished that they were dead; 19 percent had seen a dead body outside their homes.
Even more alarming, children exposed to violence suffered from a variety of personal problems and performed poorly in school.
"This fits," according to Dr. Bremner, "into the context of a range of studies -- both in animals and humans -- showing that stress can have a deleterious effect on brain systems involved in memory. This kind of damage may well underlie difficulties with new learning and cognition that cause poor academic performance in these children." It may also mean that helping these children lead better lives may not be as simple as removing them from the stressful environment.
Findings show how trauma disables normal brain functioning and highlight deficits in basic mechanisms of learning and memory. Recent findings also show that a common neurological basis explains altered emotional responses in veterans with PTSD, and that fear learning caused by trauma is different from other types and may explain why it is more difficult to treat. |
A social program that works. Where's the funding?
Executives who think they do not deserve their position tend to work among incompetent employees to justify themselves, according to new research. Qualified people prefer to work with competent and sociable partners in jobs that imply responsibility. However, persons who think they are unable to hold a specific job try to work with less competent and sociable partners. Researchers warn that people who have power do not always exercise it properly. |
Scientists have known for years that people living in poverty have poorer health and shorter lifespans than the more affluent. Now researchers have identified several key mechanisms in 13-year-olds that may help explain how low socioeconomic status takes its toll on health. |
Teenagers and adults often don't see eye to eye, and new brain research is now shedding light on some of the reasons why. Although adolescence is often characterized by increased independence and a desire for knowledge and exploration, it also is a time when brain changes can result in high-risk behaviors, addiction vulnerability, and mental illness, as different parts of the brain mature at different rates. Recent imaging studies in humans show that brain development and connectivity are not complete until the late teens or early twenties. |
Media reports warn of online predators, hate groups and other 'digital dangers' lurking in online social spaces, and those dangers are not to be taken lightly, says one educational psychology professor. "But we may do adolescents a disservice when we curtail their participation in these spaces, because the educational and psychosocial benefits of this type of communication can far outweigh the potential dangers," according to new research. |
A community-based weight control program has succeeded in reducing the prevalence of overweight children for two years. Changes in dietary intake, particularly in the reduction of consumption of sweetened beverages (e.g., soda) made the biggest difference. The girls did not appear to significantly increase their physical activity, which suggests that even without increased exercise, a proper diet can control weight gain in high-risk young girls. |
A new class of brain cells -- mirror neurons -- are active both when people perform an action and when they watch it being performed. Some scientists speculate that a mirror system in people forms the basis for social behavior, for our ability to imitate, acquire language, and show empathy and understanding. It also may have played a role in the evolution of speech. Mirror neurons were so named because, by firing both when an animal acts and when it simply watches the same action, they were thought to "mirror" movement, as though the observer itself were acting. |
Among children of mothers with low education levels, those who receive regular care from other adults during preschool years may be less likely to have problems with physical aggression, according to a new article. |
New research from the burgeoning field of neuroeconomics examining how people place value on money and other items is helping scientists to decipher how and why people make the decisions they do. Imaging studies of people experiencing real financial losses show activity in brain areas related to processing emotions, a finding that may account for the irrational behavior of financial professionals in high-risk settings. Additional imaging work shows that the same neural network responsible for rationally evaluating risky opportunities is also responsible for the irrational behavior of decision-makers when they face ambiguous situations. |
Young people with asthma are about twice as likely to suffer from depressive and anxiety disorders than are children without asthma, according to a new study. Previous research had suggested a possible link in young people between asthma and some mental health problems, but this study is the first showing such a strong connection. |
A Swiss study suggests that teens who use only cannabis appear to function better than those who also use tobacco, and are more socially driven and have no more psychosocial problems than those who abstain from both substances, according to a new report. |
