Race,Education, and Joblessness in the Inner City, 1970–1990

In When Work Disappears, William Julius Wilson argues that the difficulties black inner-city residents face in finding work has more to do with their failure to acquire the kinds of education, skills, and work habits required by changes in the urban labor market than with racial discrimination. In this essay, I argue that this notion tends both to obscure the substantial gains African-Americans have made in education and to discount the degree to which race continues to mediate the relationship between educational achievement and labor market outcomes. Although there is no question that the economic position of those with little education has deteriorated badly over the last two decades, absent policies that address the persistent racial disparities in employment, reforming education by itself will not substantially improve African-American employment opportunities or reduce black joblessness in the inner city.     

Robotics for High School Students in a University Enviroment

The Young Scholars Program at the Institute for Systems Research of the University of Maryland at College Park is an innovative summer research experience for high school students from Maryland, Virginia, and Washington D.C. Its goal is to steer talented high school seniors toward higher education and careers in science and engineering. One particularly popular component of this program is a two‐week mini‐coursein robotics. This course utilizes the resources of the Intelligent Servosystems Laboratory of the university to introduce and demonstrate theoretical and practical aspects of robotics. This paper reports on the characteristics that make this a unique effort in robotics‐related education for both the Young Scholars Program participants and the small group of University of Maryland graduate students who have been responsible for the development and instruction of this course.     

Similarities in siblings' experiences of neglectful parenting behaviors

OBJECTIVE: Researchers and policymakers typically assume that within families, individual children are at an equivalent risk of neglectful behaviors. There is evidence that siblings experience differential parental treatment, and some research suggests that parents may maltreat their children to differing degrees. However, because neglect is typically a family-level construct, there may be a high correlation between siblings for this type of parental behavior. Therefore, our objectives were to investigate the extent to which siblings reported similar parental neglectful behaviors, whether sibling correlations for family-level types of neglectful behaviors were greater than those for child-specific forms of neglectful behaviors, whether high-risk groups differed from lower-risk groups in similarity for sibling reports for neglectful behaviors, and factors predicting differences in sibling reports of parental neglectful behaviors. METHOD: We assessed parental neglectful behaviors using child reports for 59 sibling pairs, representing both clinical and community samples. All children completed the Multidimensional Neglectful Behaviors Scale, which measures both child-specific and family-level neglectful parenting behaviors. RESULTS: Sibling intraclass correlations for neglectful behaviors were high and significant, and there were no differences in sibling correlations between clinical and community samples. Furthermore, there were no differences in correlations for family-level and child-specific items. Opposite sex siblings reported greater differences in parental neglectful behaviors, with boys reporting more neglectful behaviors than girls. CONCLUSIONS: Siblings report similar neglectful parenting behaviors, regardless of whether the family is high-risk or not, and whether neglectful behaviors are measured as a family-level or child-specific phenomenon.     

TERMS OF INCLUSION: UNITY AND DIVERSITY IN PUBLIC EDUCATION

Abstract In this review essay, Harvey Kantor and Robert Lowe explore the history of the culture wars in public education in the United States. Drawing on three books — David Tyack’s Seeking Common Ground, Jonathan Zimmerman’s Whose America? and Amy Binder’s Contentious Curricula— Kantor and Lowe review the history of struggles over the content of history texts and over the place of religion and religious values in the classroom. They suggest that while these struggles have been partially successful in freeing public education from the racial and ethno‐religious particularisms that informed its origins, the more inclusive curriculum that resulted from these efforts has been rendered largely symbolic by the persistence of segregation and the inequality of resources that accompanies it.     

Comparing two forms of dynamic assessment and traditional assessment of preschool phonological awareness

The goal of the current study was to compare two forms of dynamic assessment and standard assessment of preschool children's phonological awareness. The first form of dynamic assessment was a form of scaffolding in which item formats were modified in response to an error so as to make the task easier or more explicit. The second form of dynamic assessment was direct instruction of the phonological awareness tasks. The results indicate that preschool children's phonological awareness can be assessed using standard assessment procedures, provided the items require processing units larger than the individual phoneme. No advantage was found in reliability or validity for either dynamic assessment condition relative to the standard assessment condition. Dynamic assessment does not appear to improve reliability or validity of phonological awareness assessments when preschool children are given tasks that they can perform using standard administration procedures.     

The TREC-5 Confusion Track: Comparing Retrieval Methods for Scanned Text

A known-item search is a particular information retrieval task in which the system is asked to find a single target document in a large document set. The TREC-5 confusion track used a set of 49 known-item tasks to study the impact of data corruption on retrieval system performance. Two corrupted versions of a 55,600 document corpus whose true content was known were created by applying OCR techniques to page images. The first version of the corpus used the page images as scanned, resulting in an estimated character error rate of approximately 5%. The second version used page images that had been down-sampled, resulting in an estimated character error rate of approximately 20%. The true text and each of the corrupted versions were then searched using the same set of 49 questions. In general, retrieval methods that attempted a probabilistic reconstruction of the original clean text fared better than methods that simply accepted corrupted versions of the query text.
