This paper explores the connections between Physical Education, nationalism and citizenship in England and Wales focusing upon how education legislation, in particular the National Curriculum (NC) and Local Management of Schools (LMS), are implicated in the cultural production of ideational differences between and amongst the peoples of England and Wales. As our previous research has centred heavily on the making and implementation of education policy and PE in England, we take this opportunity to adjust our gaze and focus squarely on issues of cultural production in Wales, particularly relationships between the construction of images of Welsh identity and education policy and practice relating to PE and sport in schools. The analysis highlights that tendencies towards a narrow, conservative, cultural restoration are as evident in Wales as they are in England and obstruct progression towards more innovative and progressive ideals. 相似文献

Abstract This study examined dissonance in physical activity (PA) between two youth-specific hip-derived intensity cut-points for the Actiwatch (AW), and compared PA between hip and wrist placements using site-specific cut-points. Twenty-four children aged 11.2?±?0.5 years wore the AW on the right hip and non-dominant wrist during a typical school day. Minutes of sedentary behaviour and vigorous activity were greater using Puyau et al. (2002) cut-points, but light, moderate, and moderate-to-vigorous (MVPA) were greater when derived using Puyau et al. (2004) cut-points (P?相似文献

A Review of Research on School Bullying Among African American Youth: An Ecological Systems Analysis
Desmond Upton Patton Jun Sung Hong Abigail B. Williams Paula Allen-Meares 《Educational Psychology Review》2013,25(2):245-260
School bullying and peer victimization are social problems that affect African American youth across various environmental contexts. Regrettably, many of the empirical research on bullying and peer victimization among African American youth has examined individual and direct level influences in silos rather than a constellation of factors occurring in multiple settings, such as home, school, and neighborhood. As a holistic model, the social–ecological framework provides a context with which to situate and interpret findings and draw implications from a broader psychosocial framework, which can be applicable across various systems. We utilize Bronfenbrenner’s (American Psychologist 32:513–531, 1977) social–ecological framework as a springboard for investigating the accumulation of risk contributors and the presences of protective factors in relation to school bullying and peer victimization of African American youth. More specifically, we examine the risk and protective factors occurring in the micro- (i.e., parents, peers, school, and community), exo- (i.e., parental stress), and macrosystem levels (i.e., hypermasculinity, and gender role beliefs and stereotypes). We then discuss implications for research and school-based practice. 相似文献

There are many influences on how assessors grade themselves and others. Oral presentations are useful for exploring such factors in peer, self‐ and tutor marked assessments, being rapidly completed and assessed, commonly used in HE and very difficult to anonymize. This opportunistic study examined the effects of gender and level of attainment on the triangulation of marks awarded to student presenters. Grades generated by peer assessment were associated more strongly with tutor‐awarded marks than those from self‐assessment. For self‐assessment there was a strong effect of gender (female students undervalued their performance compared with tutor grades). Peer assessment produced higher marks than from tutors, perhaps because of the close‐knit community developed during residential courses. For tutor marks, the greatest variability was at the lower end of the scale, whereas peer assessors were most variable when marking students who self‐evaluated or peer assessed highly. Students awarded a narrower range of marks to peers compared with tutors, but when self‐assessing used a larger range. Presentations by students who admitted to little sleep the night before received lower grades from both peers and tutors, but this was not reflected by self‐assessments, suggesting they were unaware of their poorer performances. Sessions with fewer talks (four rather than seven) reduced the ‘dip’ in marks previously observed in the middle of sessions. Findings are discussed in the context of bias in this mode of assessment. 相似文献

Food-deprived rats were exposed to a schedule in which a brief stimulus was presented approximately once every 60 sec. The first leverpress to occur in the presence of the stimulus always turned it off, and produced a food pellet 50% of the time. When the rats were given concurrent access to water, a running wheel, or both, drinking predominated during intervals initiated by pellet delivery, while running predominated during intervals initiated without food. When allowed to obtain all of their food pellets at the beginning of a session, rats drank less and ran more than when the intermittent schedule was in effect, and most drinking occurred within the first half of the session, while running was distributed throughout the session. Adjunctive drinking and wheel running appear to be functionally different, drinking being schedule-induced and food-bound, running being neither. 相似文献

This paper identifies ‘quality’ as an internationally relevant concept to be problematised in contemporary debates about physical education (PE). Drawing on the conceptualisation of curriculum by B. Bernstein in 1977, pedagogy and assessment as three inter-related message systems of schooling, the paper presents and explores curriculum, pedagogy and assessment as three fundamental dimensions of ‘quality PE’. Discussion addresses what quality in each dimension may mean in PE, and demand in practice. Contemporary initiatives in Australia and New Zealand provide a reference point for exploring the prospective application of quality conceptualised in terms of the three inter-related dimensions. Attention is drawn to frameworks in mainstream education that may be utilised in endeavours to critically review current practices, and inform developments directed towards achieving quality in PE. It is argued that achieving quality in PE requires that quality is pursued and demonstrated within and across curriculum, pedagogy and assessment, and that meanings of quality always need to be contextualised in cultural, social and institutional terms. 相似文献

This paper contributes to sport, sociology and the body literature by exploring the ‘exposure and effect’ of culture, in particular bodily practices placed on three adolescent swimmers immersed in the Australian swimming culture using an ethnographic framework. The research reported is particularly notable as it addresses two distinct time points in the swimmers’ lives. The first section explores the adolescent experiences of three female swimmers within the cultural context of Australian swimming by articulating some of the specific body practices and ‘memes’ (ideas, symbols and practices) that they were exposed to and/or engaged within relation to the body. The second section of this paper focuses on the same three swimmers in the ‘present day’, some 10–30 years after being immersed in the Australian swimming culture as adolescents. It excavates their body practices and the relationships they now have with their body, and thus pursues the sustained impact of the body practices and ‘memes’ they were exposed to as adolescents. Analysis employs concepts drawn mainly from Foucault, particularly his thesis in regard to ‘disciplinary power’, ‘regulation’ ‘classification’ and ‘surveillance’. At a club (amateur) and National level, Australian swimming is revealed as an institution, a site and culture where particular techniques of power have become concentrated and have been brought to bear on individuals in systematic ways, with sometimes damaging effects arising for athletes’ long-term health and well-being, particularly if the individuals concerned continue to engage with cultural practices in regard to the body post-career. 相似文献

This study examined a moderated mediation model among 314 Black adolescents aged 13–18. The model included general coping strategies (e.g., active, distracting, avoidant, and support‐seeking strategies) as mediators and racial identity dimensions (racial centrality, private regard, public regard, minority, assimilationist, and humanist ideologies) as moderators of the relation between perceived racial discrimination and depressive symptoms. Moderated mediation examined if the relation between perceived racial discrimination and depressive symptoms varied by the mediators and moderators. Results revealed that avoidant coping strategies mediated the relation between perceptions of racial discrimination and depressive symptoms. The results indicated that avoidant coping strategies mediated the relation between perceived racial discrimination and depressive symptoms among youth with high levels of the minority/oppressive ideology. 相似文献
