Exclusion and victimization by classmates were related to levels and diurnal change in cortisol in 97 fourth graders (53% boys, M = 9.3 years). Number and quality of friendships were considered as moderators. Salivary cortisol was collected 5 times daily on 2 school days. Excluded children had elevated cortisol levels at school and a flattened diurnal cortisol curve, suggesting hypothalamic-pituitary-adrenocortical (HPA) axis dysregulation. This effect was weaker for children with more friends or better friendships. Victimization was not associated with cortisol level or change. The results demonstrate the role of HPA activity in peer group processes and indicate that group and dyadic factors interact in predicting stress in the peer group. 相似文献

This study examined the relationships among academic enablers (i.e., engagement, interpersonal skills, motivation, study skills) and academic achievement in children with and without high levels of parent‐rated symptoms of inattention, impulsivity, and hyperactivity (Symptoms of IIH Group). The study included 69 participants (29 [42%] in the IIH Group and 40 [58%] in the Comparison Group), with 33 boys and 36 girls in the third through fifth grades. The researchers found significant differences on the measure of academic enablers, including engagement, interpersonal skills, motivation, and study skills, in which participants in the Comparison Group received higher scores. In addition, several academic enablers mediated the relationship between symptoms of inattention, impulsivity, and hyperactivity and the academic outcomes of reading and teachers' ratings of total academic skills. © 2011 Wiley Periodicals, Inc. 相似文献

Research over the past few decades has highlighted the importance of social and emotional competence in preschool children on later academic, social, and psychological outcomes. Children who are socially and emotionally competent have increased socialization opportunities with peers, develop more friends, have better relationships with their parents and teachers, and enjoy more academic and social successes. Children who lack social and emotional competence are at risk for reduced socialization opportunities, rejection, withdrawal, behavioral disturbance, and achievement problems. Intervention programs that target social–emotional development in preschool are ideally situated to bolster these skills before the problems exacerbate. In this paper, research on the importance of social and emotional competence in young children is reviewed as it relates to immediate and long‐term outcomes. Assessments of social and emotional development and behavioral adjustment are briefly reviewed, followed by a review of intervention programs with demonstrated empirical efficacy. Although preliminary evidence supports the utility of these intervention programs, additional research on short‐ and long‐term efficacy is recommended, and more programs designed specifically for early childhood are needed. © 2011 Wiley Periodicals, Inc. 相似文献

Objectives
To present a detailed confession from a perpetrator of Shaken Baby syndrome.Methods
Case study.Results
We present a confession of Shaken Baby syndrome describing how the perpetrator severely injured a 3 year old with repeated bursts of acceleration-deceleration (shaking). The child sustained retinal and intracranial hemorrhage. Details of the confession and circumstances by which it was obtained lead us to believe its accuracy.Conclusions
Accurate perpetrator confessions offer useful windows into realities and pathophysiology of abusive head trauma. 相似文献975.

Little is known about the experiences of Lesbian, Gay, Bisexual, Transgender and Questioning (LGBTQ) university students in the UK. One of the main reasons for this seems to be that the monitoring of sexual orientation and gender identity is not routinely undertaken and is not consistent across all Higher Education establishments. This can mean that identifying LGBTQ students is not always easy, and one result of this is that LGBTQ students who have lesser rates of student satisfaction are not being targeted for improvement strategies, which are intended to increase satisfaction and increase student survey scores. One study that gives some new insight into the experiences of LGBTQ students in England was conducted in collaboration with the LGBT service provider METRO and The University of Greenwich. This article explores some of the main findings from that study and discusses the implications these may have for Higher Education and those establishments wishing to increase satisfaction and wider participation with sexual minority students. 相似文献

This paper reports on a case study conducted in an American university investigating the role of feedback within a distance education environment. Based on data gathered from online and hybrid undergraduate students in a teacher education program and supported by existing research, we describe how we support online learners by implementing a feedback system that incorporates multi-draft formative assessments and various feedback strategies. We describe these strategies (i.e. explicit feedback directions and feedback surveys) as well as data from formative assessments to demonstrate the impact of clear expectations and feedback on student performance in distance education. We present recommendations for online feedback and propose a feedback model for further study. 相似文献

This article explores how ethnic minority students in Hong Kong secondary schools discursively construct their identities in relation to culture, heritage, and social discourse. It finds that the ethnic minority students negotiate their identities within multiple positioning from parents, school, and the broader social discourse on minority languages and cultures. It also finds that they construct contradictory language ideologies when attempting to legitimate their heritage languages and to illegitimate the status of Chinese in the social context. The findings indicate that the participants tend to establish an essentialized cultural difference between their heritage culture and host culture. It argues that fixed and stereotyped views towards language practices and culture may lead to antagonistic relations between the ethnic minority students and locals, and become obstacles to their socialization and integration into the mainstream community. The implications for establishing a flexible and relational view on cultural differences and language use are explored. 相似文献

Children from language minority homes reach school age with variable dual language skills. Cluster analysis identified four bilingual profiles among 126 U.S.-born, 5-year-old Spanish–English bilinguals. The profiles differed on two dimensions: language balance and total language knowledge. Balance varied primarily as a function of indicators of the relative quantity and the quality of their language exposure (amount of home exposure and maternal education in each language). Total language knowledge varied primarily as a function of indicators of children’s language learning ability (phonological memory and nonverbal intelligence). English dominance was more prevalent than balanced bilingualism; there was no Spanish dominant profile, despite average Spanish dominance in home language use. There was no evidence of a tradeoff between English and Spanish skills. 相似文献

Bringing Engineering Design into High School Science Classrooms: The Heating/Cooling Unit 总被引:5,自引:4,他引:1

Infusing engineering design projects in K-12 settings can promote interest and attract a wide range of students to engineering
careers. However, the current climate of high-stakes testing and accountability to standards leaves little room to incorporate
engineering design into K-12 classrooms. We argue that design-based learning, the combination of scientific inquiry and engineering
design, is an approach that can be used to meet both K-12 educators’ and engineering advocates’ goals. This paper describes
an 8-week high school curriculum unit, the Heating/Cooling System, in which engineering design is used to teach students central and difficult chemistry concepts such as atomic interactions,
reactions, and energy changes in reactions. The goals of the paper are to (1) describe this successful design-based unit,
(2) provide guidelines for incorporating design-based learning into other science topics, and (3) provide some evidence of
its value for teaching difficult chemistry concepts and increasing interest in engineering careers. 相似文献
