But I like PE: factors associated with enjoyment of physical education class in middle school girls     

Barr-Anderson DJ  Neumark-Sztainer D  Schmitz KH  Ward DS  Conway TL  Pratt C  Baggett CD  Lytle L  Pate RR 《Research quarterly for exercise and sport》2008,79(1):18-27

The current study examined associations between physical education (PE) class enjoyment and sociodemographic, personal, and perceived school environment factors among early adolescent girls. Participants included 1,511 sixth-grade girls who completed baseline assessments for the Trial of Activity in Adolescent Girls, with 50% indicating they enjoyed PE class a lot. Variables positively associated with PE class enjoyment included physical activity level, perceived benefits of physical activity, self-efficacy for leisure time physical activity, and perceived school climate for girls' physical activity as influenced by teachers, while body mass index was inversely associated with PE class enjoyment. After adjusting for all variables in the model, PE class enjoyment was significantly greater in Blacks than in Whites. In model testing, with mutual adjustment for all variables, self-efficacy was the strongest correlate of PE class enjoyment, followed by perceived benefits, race/ethnicity, and teachers' support for girls' physical activity, as compared to boys, at school. The overall model explained 11% of the variance in PE class enjoyment. Findings suggest that efforts to enhance girls' self-efficacy and perceived benefits and to provide a supportive PE class environment that promotes gender equality can potentially increase PE class enjoyment among young girls.  相似文献   

Pedometer reliability, validity and daily activity targets among 10- to 15-year-old boys     

Jago R  Watson K  Baranowski T  Zakeri I  Yoo S  Baranowski J  Conry K 《Journal of sports sciences》2006,24(3):241-251

The aims of this study were to: (1) determine whether the number of pedometer counts recorded by adolescents differs according to the adiposity of the participant or location on the body; (2) assess the accuracy and reliability of pedometers during field activity; and (3) set adolescent pedometer-based physical activity targets. Seventy-eight 11- to 15-year-old Boy Scouts completed three types of activity: walking, fast walking and running. Each type was performed twice. Participants wore three pedometers and one activity monitor during all activities. Participants were divided into groups of normal weight (BMI < 85th percentile) and at risk of being overweight (BMI > or = 85th percentile). Intra-class correlations across the three activities indicated reliability (r = 0.51 - 0.92, P < 0.001). This conclusion was supported by narrow limits of agreement that were within a pre-set range that was practically meaningful. Multivariate analysis of covariance indicated adiposity group differences, but this difference was a function of the increased stature among the larger participants (P < 0.001). Ordinary least-squares regression models and multi-level regression models showed positive associations between the number of pedometer and activity monitor counts recorded by the three groups of participants during all activities (all P < 0.001). The mean number of counts recorded for all participants during the fast walk was 127 counts per minute. In conclusion, the pedometers provided an accurate assessment of adolescent physical activity, and a conservative estimate of 8000 pedometer counts in 60 min is equivalent to 60 min of moderate to vigorous physical activity.  相似文献   

A comparison between mainstream and action sport industries in Australia: A case study of the skateboarding cluster     

Pamm Kellett  Roslyn Russell 《Sport Management Review》2009,12(2):66-78

The action sport industry is a high growth sector that attracts the lucrative Generation Y market. Although there is a growing body of literature that examines the characteristics and traits of the Generation Y market as consumers of action sports, little is known about the supply side of the action sports industry. This paper illustrates through the example of the skateboarding sport cluster, that this sector has evolved in an organic, almost chaotic manner very different to that of the mainstream sports industry. Entrepreneurs have taken advantage of the open system, the lack of formal boundaries and the risk loving nature of the market to grow the sector into a very profitable industry. The paper specifically illustrates the differences to mainstream sports in relation to provision of facilities, program development and pathways and the roles of suppliers, councils and program developers.  相似文献

Children's ideas about evaporation     

Terry Russell  Wynne Harlen  Dot Watt 《International Journal of Science Education》2013,35(5):566-576

This article reports on research conducted as part of the Primary Science Processes and Concept Exploration (space) Project. The background to, and orientation of, space is briefly described.

Classroom‐based research into children's thinking about evaporation is reported. This work was conducted in close collaboration with teachers of the 5‐11 years age range with the intention of establishing the viability of the techniques for eliciting ideas and managing subsequent interventions within classrooms.

Children's thinking in relation to three main evaporation phenomena are discussed. Ideas about evaporation were categorized by reference to notions of conservation, change of location and change of form of the water.  相似文献

The secret life of the chemical bond: students’ anthropomorphic and animistic references to bonding     

Keith S. Taber  Mike Watts 《International Journal of Science Education》2013,35(5):557-568

This paper discusses students’ use of anthropomorphic language in science, and in particular calls upon some examples from research into student understanding of chemical bonding. It is argued that anthropomorphic language is common amongst scientists as well as science students. A simple classification of such instances is suggested to distinguish between those examples that are useful in aiding communication and understanding, and those which merely stand in place of such understanding.  相似文献
