This study examined how activity type influenced heart rates and time spent in target heart rate zones of high school students participating in physical education classes. Significantly higher average heart rates existed for fitness (142 +/- 24 beats per minute [bpm]) compared to team (118 +/- 24 bpm) or individual (114 +/- 18) activities. Similar results occurred for the percentage of activity time spent within a target heart rate zone (fitness 81.7 +/- 15.9%, individual 68.4 +/- 30.5%, and team 60.6 +/- 30.5%). Boys attained higher heart rates during team activities, while female students had higher rates during individual activities indicating male and female adolescents respond differently to activity types. The highest mean heart rates were observed during fitness activities. 相似文献

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

Workbook reading achievement of five second-grade girls was assessed under two teacher-contact contingencies. Under one contingency, teacher contacts were made during on-task behavior. Under the other contingency, differential reinforcement of an incompatible behavior (DRI) was in effect, with teacher contacts contingent on students' hand-raising behavior. Both reading achievement and time on task were greater under the on-task contingency than under DRI for hand raising. 相似文献

Students in an experimental and a control high school were compared in the fall and spring on their Locus of Control scores. An Open Campus policy was instituted in the experimental school, which essentially gave its upperclassmen the same freedom and responsibilities as those of a community college student. The experimentals increased significantly more than controls in internal control. Students reported that the Open Campus experience led to: after school jobs, greater time to pursue own interests, feelings of freedom, autonomy, and responsibility, a decline in grades due to “goofing off,” and less time for social activities. 相似文献

This short bibliography is not supposed to be a comprehensive survey of all that has been written about gender and science. Its much more modest aim is to mention a few of the many books that have been published on this subject in recent years, and to give some indication of their contents. By doing this I hope to provide readers with a starting point from which to pursue an interest in any particular aspect of the subject. 相似文献

A current turn of interest in notions of the ‘learning economy’ and the ‘learning society’ is fuelling discussions on promoting education, training and learning in contemporary organizations and workplaces. Although the education of workers has been variously theorized and practised throughout the 20th century, the current debates are marked by a prevailing economic perspective that places emphasis on constructing ‘learning organizations’ and on ‘human resource’ learning in service of organizational strategies for innovation and competitive advantage in economic activities. Critics point out that economic and managerial models scarcely attend to the human subjectivity of the learner‐worker and the worker's diverse learning interests. Broader socio‐cultural ends of worker learning such as lifelong human development and participatory citizenship in democratic society are very often overlooked. This article offers a critical discussion of current conceptions of learning organizations and learning workers. It argues that the prevailing focus on techno‐economic imperatives and of obscured managerial elite interests in organizations currently circumscribe and delimit learning in production organizations. It proposes that a more comprehensive approach to learning in organizations attends explicitly to the needs and interests of workers as learning persons. Taking a longer view, it proposes that organizational and worker learning may generate not only improved work practices but may regenerate links between lifelong learning, societal democratic citizenship and civilized organizations. 相似文献

This analysis of activists' and bureaucrats' politicking for gender policy in Australia demonstrates the utility of discourse analysis. Feminist policy initiatives are special: they challenge hegemony and they circulate counter discourse. Policy elites try to manage and discredit them. Traditional policy frameworks are used to identify policy with policy mechanisms, policy communities, value shifts and the like. But the use of policy discourse analysis for this Australian story elicits key strategies for constructing and managing a counter narrative and maintaining a counter public of outsiders using insiders to institutionalize gender policies even as equity and social justice value priorities recede. 相似文献
