Within the substantial body of research examining the professional knowledge of physical education (PE) teachers one particular area remains relatively under-explored: namely, their understandings of young people's participation in leisure-sport and the implications of this, if any, for the practice of PE. There are grounds for thinking, however, that in this aspect of their professional knowledge PE teachers might not be as conversant with patterns of participation—among young people, generally, and their own pupils, in particular—as one might expect. In order to examine this tentative hypothesis, the present study involved focus groups with a total of 29 PE teachers at six secondary schools in England. A central finding of the study was that PE teachers' perceptions of their youngsters' leisure-sport lives tended to be characterized by a blend of myth and reality. Many teachers, for example, underestimated the levels of participation in leisure-sport both of their own pupils and the 15–16 years age group, generally. Nevertheless, the teachers' observations regarding what amounted to growing and diversifying sporting repertoires among their pupils were, to a greater or lesser degree, commensurate with the profiles reported by the pupils, and with wider trends associated with the changing lifestyles and preferences of young people. The paper concludes by briefly locating this study of professional knowledge within the sociology of knowledge, while observing that the content and form of PE for Year 11 pupils at the six schools in this study appeared to be informed by the common-sense, everyday knowledge of PE teachers rather than by evidence from national or local surveys of young people or studies of their own pupils. 相似文献

Based on quantitative data from the Norwegian Statistisk Sentralbyrå (Statistics Norway) study of Mosjon, Friluftsliv og Kulturaktiviteter, this paper explores trends in Norwegians' participation in sports, with a focus on young people. Norway boasts particularly high levels of sports participation as well as sports club membership and young Norwegians are the quintessential sporting omnivores. Among other things, the Statistics Norway study reveals substantial increases in participation (among young people and females especially) during the period 1997–2007, a shift in the peak of participation to the late teenage years, a relatively high level of lifelong participants, a re-bound effect in the post-child rearing years and a growth in lifestyle sports. Young Norwegians grow up in a socio-economic context of relative equality between the sexes and high standards of living. An abundance of natural and artificial outdoor and indoor sporting facilities alongside a well-established voluntary sports club sector and an elementary school system that emphasizes physical exercise and recreation, as well as high levels of parental involvement, add to the favourable socio-economic conditions to create seemingly optimal circumstances for sports participation. All these reinforce the sporting and physical recreation cultures deeply embedded in Norwegian society and embodied by the very many middle-class parents in a country which, for the time being at least, remains relatively young in demographic terms. In terms of lessons to be learned for policy towards sports and physical education beyond Norway, there may be grounds for some optimism around parental involvement in children's sport as well as the potential appeal of lifestyle sports. That said, it is likely to be the greater socio-economic equalities in Scandinavian countries such as Norway that make them unrealistic benchmarks for sports participation elsewhere. 相似文献

The purpose of this study was to examine whether the relationships between contextual factors (i.e., autonomy-supportive vs. controlling coaching style) and person factors (i.e., autonomous vs. controlled motivation) outlined in self-determination theory (SDT) were related to prosocial and antisocial behaviors in sport. We also investigated moral disengagement as a mediator of these relationships. Athletes' (n = 292, M = 19.53 years) responses largely supported our SDT-derived hypotheses. Results indicated that an autonomy-supportive coaching style was associated with prosocial behavior toward teammates; this relationship was mediated by autonomous motivation. Controlled motivation was associated with antisocial behavior toward teammates and antisocial behavior toward opponents, and these two relationships were mediated by moral disengagement. The results provide support for research investigating the effect of autonomy-supportive coaching interventions on athletes' prosocial and antisocial behavior. 相似文献

Athens sits in a basin approximately 450 km2 in area, surrounded by mountains and open sea. Anthropogenic emissions in conjunction with the topographical and meteorological conditions can result in high air pollution within the city. The pollutants of concern for athletes competing in Athens 2004 appear to be nitrogen dioxide (NO2), ozone and particulate (PM10) pollution. Exposure to elevated ozone concentrations has been reported to give rise to symptoms that include cough, chest pain, difficulty in breathing, headache, eye irritation and a decrease in forced expiratory volume in one second. All of these effects are likely to impact upon performance, and several studies of cyclists suggest this to be the case. In contrast, the impact of ambient concentrations of NO2 appears to be negligible on normal activities, but at high exercise intensities the impact remains unclear. The use of currently available information and models to predict the effect of ozone and other pollutants on elite athletes is problematical, since such models are based upon significantly lower ventilation rates than those achieved by some elite athletes. In addition, it is already known that the response to ozone can vary somewhat between individuals. Since the individuals who will be competing in Athens are physiologically very different to the participants in most published studies, it is difficult to predict individual responses. There is some evidence to indicate that adaptation to the adverse health and performance effects of ozone can occur, so that performance is partially recovered on re-exposure. The adaptation is not seen in all studies and appears to be dependent on several factors, including the initial sensitivity of the individual to ozone. Antioxidant supplementation has also been shown in some studies to partially ameliorate the adverse effects of ozone by counteracting the oxidative stress mechanism associated with this pollutant. Whether this transfers to performance enhancement per se remains unclear at present. Additional research is required to gain a sound understanding of the effects of a complex mixed air pollution exposure on the pulmonary function and performance of athletes exercising at high work intensities. 相似文献

This paper describes a small‐scale study of what the authors describe as the ecosystemic approach to changing chronic problem behaviour. The study was undertaken with a group of twelve Leicestershire primary teachers. The technique is briefly described and then teachers' responses to it and its effectiveness are discussed. Four case study examples are presented and finally its potential is considered. Although in this case the work was undertaken with primary teachers, this is an approach which could also be useful at secondary level. 相似文献
