This article explores young women's accounts of the role that school sex education had in their learning about sex. It focuses on the influence of school sex education on behaviour, the importance of timing in understanding its utility, and the extent to which other sources of information complement or supplement school sex education. Thirty in-depth interviews and eight group discussions were conducted with female pupils from six schools in the east of Scotland. Nearly all of those interviewed cited school as a useful source in learning about sex. In particular, lessons intended to develop pupils' skills were valued. These were thought likely to influence behaviour positively in the future, although only one person could illustrate how this had already happened. A common feature of accounts was that school sex education had been delivered 'too late' for themselves or their peers, and it tended to be seen as an introduction or as supplementary to other sources, particularly friends, magazines and mothers. The utility of school sex education should not be dismissed but more attention should be given to the needs of those who become sexually active in their early teens.  相似文献

This paper presents a mixture item response tree (IRTree) model for extreme response style. Unlike traditional applications of single IRTree models, a mixture approach provides a way of representing the mixture of respondents following different underlying response processes (between individuals), as well as the uncertainty present at the individual level (within an individual). Simulation analyses reveal the potential of the mixture approach in identifying subgroups of respondents exhibiting response behavior reflective of different underlying response processes. Application to real data from the Students Like Learning Mathematics (SLM) scale of Trends in International Mathematics and Science Study (TIMSS) 2015 demonstrates the superior comparative fit of the mixture representation, as well as the consequences of applying the mixture on the estimation of content and response style traits. We argue that methodology applied to investigate response styles should attend to the inherent uncertainty of response style influence due to the likely influence of both response styles and the content trait on the selection of extreme response categories.  相似文献

Little is known about how children's value priorities develop over time. This study identifies children's value priority profiles and follows their development during middle childhood. Australian children (N = 609; ages 5–12 at Time 1) reported their values over 2 years. Latent Transition Analysis indicated four profiles: Social-Focus, Self-Focus, Growth-Focus and Undifferentiated. Within person development was characterized by profile stability or transfer to the Social-Focus profile. Younger children were more likely to have an Undifferentiated profile (or Self-Focus among boys) than older ones. Girls were more likely to have a Social-Focus profile or transfer to it, and less likely to have a Self- or Growth-Focus profile than boys. Social-Focus profile membership over time predicted more prosocial and less aggressive behavior.  相似文献

Seventy-nine 3-year olds and their mothers participated in a laboratory-based task to assess maternal hostility. Mothers also reported their behavioral regulation of their child. Seven years later, functional magnetic resonance imaging data were acquired while viewing emotional faces and completing a reward processing task. Maternal hostility predicted more negative amygdala connectivity during exposure to sad relative to neutral faces with frontal and parietal regions as well as more negative left ventral striatal connectivity during monetary gain relative to loss feedback with the right posterior orbital frontal cortex and right inferior frontal gyrus. In contrast, maternal regulation predicted enhanced cingulo-frontal connectivity during monetary gain relative to loss feedback. Results suggest parenting is associated with alterations in emotion and reward processing circuitry 7–8 years later.  相似文献

Acculturation consists of multiple domains (i.e., cultural practices, identifications, and values). However, less is known about how acculturation processes influence each other across multiple domains of acculturation. This study was designed to investigate transition patterns of acculturative processes within and across domains in a sample of 302 recent-immigrant Hispanic adolescents, Mage (SD) = 14.51 years (0.88) at baseline; male = 53%). Adolescents were assessed six times over a 3-year period. Latent profile analyses identified two profiles (high [or increasing] vs. low) for each domain at each timepoint. We found largely stable transition patterns in each domain over six timepoints. Importantly, sequential associations among profiles in acculturation domains were also detected. Implication for acculturation theory and research are discussed.  相似文献

This article explores the ethos of multi-denominational primary schools in the context of increasing cultural and religious diversity in the Republic of Ireland. In particular, it investigates how the official ethos is played out in day-to-day school interactions. The mixed-methods study draws on data collected from 11 community national schools focussing on the perspectives of principals, teachers and pupils. The data indicates while schools’ formal ethos sets out guiding principles and standards, a closer look reveals the specific identity of each individual school within the broader formal framework. The article presents a new perspective on school ethos research by exploring the extent to which it guides the promotion of diversity and tolerance in a multi-faith context. While the study is carried out in Ireland, it is also of interest to other jurisdictions where schools are faced with increasing religious diversity among their student population.  相似文献

Growing recognition of the complexity of children’s lives has led to strong advocacy in education research literature for greater collaboration between researchers from different paradigms to address the ‘wicked’ problems that face contemporary children and families. There is little literature, however, exploring how collaboration works in practice. This paper, drawing on researcher reflective narrative, and using Cultural Historical Activity Theory as a heuristic framework, describes and critiques the formative stages of an educational research collaborative group of five early and one mid-career early childhood education researchers (the authors), from two universities, and with quite different epistemological and ontological understandings. It outlines, from an insider perspective, some of the outcomes, challenges and tensions associated with participating in the research group, and concludes by providing some implications for policy and considerations for those contemplating forming a collaborative group.  相似文献

Student socialization in interdisciplinary doctoral education   总被引:2,自引:0,他引:2  
Interdisciplinary approaches are often seen as necessary for attacking the most critical challenges facing the world today, and doctoral students and their training programs are recognized as central to increasing interdisciplinary research capacity. However, the traditional culture and organization of higher education are ill-equipped to facilitate interdisciplinary work. This study employs a lens of socialization to study the process through which students learn the norms, values, and culture of both traditional disciplines and integrated knowledge production. It concludes that many of the processes of socialization are similar, but that special attention should be paid to overcoming organizational barriers to interdisciplinarity related to policies, space, engagement with future employers, and open discussion of the politics of interdisciplinarity.  相似文献

To understand spoken words, listeners must appropriately interpret co‐occurring talker characteristics and speech sound content. This ability was tested in 6‐ to 14‐months‐olds by measuring their looking to named food and body part images. In the new talker condition (n = 90), pictures were named by an unfamiliar voice; in the mispronunciation condition (n = 98), infants’ mothers “mispronounced” the words (e.g., nazz for nose). Six‐ to 7‐month‐olds fixated target images above chance across conditions, understanding novel talkers, and mothers’ phonologically deviant speech equally. Eleven‐ to 14‐months‐olds also understood new talkers, but performed poorly with mispronounced speech, indicating sensitivity to phonological deviation. Between these ages, performance was mixed. These findings highlight the changing roles of acoustic and phonetic variability in early word comprehension, as infants learn which variations alter meaning.  相似文献
