Examining the effects of a highly rated science curriculum unit on diverse students: Results from a planning grant

This article reports on the results of a planning grant studying the effects of a highly rated curriculum unit on a diverse student population. The treatment was introduced to 1500 eighth grade students in five middle schools selected for their ethnic, linguistic, and socioeconomic diversity. Students were given pre‐, post‐, and delayed posttests on a Conservation of Matter Assessment and measures of motivation and engagement. This quasi‐experiment found statistically significant posttest results for achievement, basic learning engagement, and goal orientation. Analyses of disaggregated data showed that subgroups of students in the treatment condition outscored their comparison group peers (n = 1500) in achievement in all cases, except for students currently enrolled in ESOL. Analysis of video data of a diverse group of four students as the unit was enacted suggests that students entered a learning environment that permitted them to function in different, but consistent ways over time; that is, the frequency of students' manipulation of objects showed a different pattern of engagement for each of the four students compared with patterns of verbal responses such as the use of scientific terms. The results of this planning grant paved the way for a large study of the scale‐up of highly rated curriculum units. © 2005 Wiley Periodicals, Inc. J Res Sci Teach 42: 912–946, 2005     

School Leaders as Political Strategists: William Boyd's Contributions to our Understanding of the Politics of Leadership

William Boyd's contributions to the education field's understanding of the political nature of school leadership are formidable. In this article, I describe the growth and development, over a roughly 30-year time span, of his key insight that successful school leaders should have the capabilities of a political strategist and that the actualization of this capacity is related to school leaders’ political and policy context. The perennial question of “who governs education” was central to Boyd's work and his various answers are important touchstones for today's educational leaders.     

Are there long-term effects of early child care?

Effects of early child care on children's functioning from 4(1/2) years through the end of 6th grade (M age=12.0 years) were examined in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (n=1,364). The results indicated that although parenting was a stronger and more consistent predictor of children's development than early child-care experience, higher quality care predicted higher vocabulary scores and more exposure to center care predicted more teacher-reported externalizing problems. Discussion focuses on mechanisms responsible for these effects, the potential collective consequences of small child-care effects, and the importance of the ongoing follow-up at age 15.     

Does cardiopulmonary resuscitation cause rib fractures in children? A systematic review

BACKGROUND: There is a diagnostic dilemma when a child presents with rib fractures after cardiopulmonary resuscitation (CPR) where child abuse is suspected as the cause of collapse. We have performed a systematic review to establish the evidence base for the following questions: (i) Does cardiopulmonary resuscitation cause rib fractures in children? (ii) If so, what are the frequency and characteristics of these fractures that may help to distinguish them from rib fractures caused by physical abuse? METHODS: We performed a literature search of original articles, references, textbooks, and conference abstracts, published in any language from 1950 to 1 October 2005. Articles were identified from ASSIA, Caredata, Medline, Ovid Medline in Process, ChildData, CINAHL, Embase, ISI Proceedings, SIGLE, Science Citation Index, Social Science Citation Index, and TRIP databases. We included all studies that addressed rib fractures and CPR in children less than 18 years, and excluded review articles, expert opinion, consensus guidelines, and studies that were significantly methodologically flawed on critical appraisal. Each study underwent two independent reviews (with a third review if there was disagreement). Each reviewer used standardized criteria for study definition, data extraction, and critical appraisal, to determine the quality of the study and to establish if it met the inclusion criteria of this systematic review. FINDINGS: Of the 427 studies reviewed, 6 were included: 1 case control, 4 cross-sectional, and 1 case series. These represent data on 923 children who underwent CPR. Three children sustained rib fractures as a result of resuscitation; all three of these had fractures that were anterior (two mid-clavicular and one costo-chondral). We did not find any child in the literature who had a posterior rib fracture due to CPR. Resuscitation was performed variably by both medical and non-medical personnel. CONCLUSION: Rib fractures after cardiopulmonary resuscitation are rare. When they do occur, they are anterior and may be multiple. As the studies performed to date did not use the most sensitive techniques for detecting rib fractures, further prospective studies of children would be valuable to provide additional clarification on this question.

The relationship of ethnic identity and ego identity status among adolescents and young adults

A multi-ethnic sample of 248, ages 13–26, was used to examine the effects of age, gender, and ethnic group membership on ethnic identity and ego identity scores. Subjects were recruited from college and public schools in a large northeastern metropolitan area. The multigroup ethnic identity measure (MEIM) was used to assess ethnic identity and ego identity status was measured by the extended objective measure of ego identity status (EOMEIS). An age by ethnic group design was employed. Consistent findings of significant ethnic group differences in levels of ethnic identity were observed. Age and ethnic group were found to contribute differently to ethnic identity and ego identity status. The relationship between ethnic identity and ego identity status was found to be pronounced among subjects of color but not as dramatic as hypothesized.
