初中女生的运动能力信念和调节方式:与愉快、努力和厌烦的关系(英文) 总被引：1，自引：1，他引：0
女生参予体育活动已经成为众所关注的问题。考察了运动能力信念、能力知觉和调节方式的关系，并且依据运动能力信念和调节方式的不同，按照愉快、努力和厌烦的水平，确定了三个不同的初中女生的动机模式。为在促进初中女生参加体育活动中考虑运动能力信念和自我决定理论提供了依据。 相似文献

This study utilised a prospective design in examining determinants of intrinsic motivation in a physical education teacher education course. At the outset of a one‐term Olympic gymnastics module students in the third year of a 4‐year degree course completed questionnaires measuring their perceived autonomy and competence regarding the module. On completion of the module, students replied to questionnaires assessing their intrinsic motivation as well as their intentions to study a gymnastics course in the future. Structural equation modelling analysis showed that both perceived autonomy and competence had effects on intrinsic motivation, although the latter was indirect through performance. Further, intrinsic motivation had a strong effect on intention. This study shows the importance of creating perceptions of autonomy in student teachers when the promotion of intrinsic motivation is desired. 相似文献

The principle of one‐to‐one correspondence is involved in sharing objects by distributive counting. Understanding one‐to‐one correspondence has been inferred from preschool children's success in sharing. This inference is questioned on methodological grounds. Twenty‐four children, aged between 3#fr1/2> and 4#fr1/2> years, took part in a study which compared their judgements of shares in conditions where the shares were either visible or invisible, equal or unequal, and of either small or large numbers of heterogeneous or homogeneous objects. Children judged better when the shares were small and visible. Whether children typically develop an understanding of one‐to‐one correspondence first in the context of sharing and then in other contexts such as counting or using guidelines remains unknown, as studies of these other contexts typically expose children to a conflict between one‐to‐one correspondence and perceptual cues. 相似文献

Innovations associated with gas and oil drilling technology, including new hydraulic fracturing and horizontal drilling techniques, have recently led to dramatic boomtown development in many rural areas that have endured extended periods of economic decline. The Marcellus Shale play, one of the world's largest gas-bearing shale formations, lies beneath approximately two-thirds of Pennsylvania, including some of the state's most economically lagging rural areas. Spurred by a state-level policy environment favorable to unconventional gas extraction, drilling activity in the last five years has rapidly increased, often with profound social, economic, and environmental implications for communities. In this paper we use schooling as a particular analytic lens for understanding the dynamics of natural resource boomtown development, community change, and how these changes may affect educational and instructional decision making. Using data from interviews and focus groups with educators and administrators in Pennsylvania communities experiencing intensive natural gas development, we discuss the multiple organizational, curricular, and educational dilemmas school leaders face in the context of both rapid, unpredictable community change, and an educational policy environment unfavorable to place-sensitive educational responses to local change. 相似文献

Different methods of ball carrying can be used when a player runs with the ball in rugby union. We examined how three methods of ball carrying influenced sprinting speed: using both hands, under the left arm and under the right arm. These methods were compared with running without the ball. Our aim was to determine which method of ball carrying optimizes sprinting speed. Altogether, 48 rugby union players (age 21±2 years, height 1.83±0.1?m, body mass 85.3±12?kg, body fat 14?±?5%; mean±s) were recruited. The players performed twelve 30-m sprints in total (each player performed three trials under each of three methods of carrying the ball and sprinting without the ball). The design of the study was a form of Latin rectangle, balanced across the trial order for each of the methods and for pairwise combinations of the methods in blocks of four per trial. Each sprint consisted of a 10-m rolling start, followed by a 20-m timed section using electronic timing gates. Compared with sprinting 20?m without the ball (2.58±0.16?s), using both hands (2.62±0.16?s) led to a significantly slower time (P?<0.05). Sprinting 20?m with the ball under the left arm (2.61±0.15?s) or under the right arm (2.60± 0.17?s) was significantly quicker than when using ‘both hands’ (P?<0.05), and both these methods were significantly slower than when running without the ball (P?<0.05). Accordingly, running with the ball in both hands led to the greatest decrement in sprinting performance, although carrying the ball under one arm also reduced the players' sprinting ability. Our results indicate that to gain a speed advantage players should carry the ball under one arm. 相似文献

We provide a wide-ranging review of health-related physical activity in children and adolescents using a behavioural epidemiology framework. In contrast to many other reviews, we highlight issues associated with true sedentary behaviours alongside physically active behaviours. Specifically, we review the evidence concerning the links between physical activity and cardiovascular disease, overweight and obesity, psychosocial measures, type II diabetes, and skeletal health. Although the evidence is unconvincing at times, several factors lead to the conclusion that promoting physical activity in youth is desirable. A review of the prevalence of physical activity and sedentary behaviours shows that many young people are active, but this declines with age. A substantial number are not adequately active for health benefits and current trends in juvenile obesity are a cause for concern. Prevalence data on sedentary behaviours are less extensive but suggest that total media use by young people has not changed greatly in recent years. Most children and adolescents do not exceed recommended daily hours of TV viewing. Physical activity is unrelated to TV viewing. We also identified the key determinants of physical activity in this age group, highlighting demographic, biological, psychological, behavioural, social and environmental determinants. Interventions were considered for school, family and community environments. Finally, policy recommendations are offered for the education, governmental, sport and recreation, health, and mass media sectors. 相似文献

Research has shown that dispositional achievement goal orientations have important effects on motivation, affect and behaviour in sport and physical activity. However, rather less is known about the relationship between perceived ethos, or climate, of physical education (P.E.) classes and subsequent motivation. The purpose of this study, therefore, was to investigate the psychometric properties of an inventory assessing P.E. class climate and the relationship of subscales of the inventory with intrinsic motivation. Second order factor analysis revealed class climate dimensions of ‘mastery’ and ‘performance’, confirming prior research. The mastery dimension scores were found to significantly enhance the prediction of intrinsic motivation beyond that accounted for by perceived competence, whereas this was not the case for performance climate scores. MANOVA showed that children perceiving their P. E. class to be high inboth mastery and performance climate reported greater intrinsic motivation and perceived competence. 相似文献
