ABSTRACT Participation in youth sport is positively associated with physical fitness and performance. The purpose of the current study was to examine if physical fitness measures during childhood and early adolescence predicted high school sport participation. Participants included youth in the Michigan State University Motor Performance Study. Measures consisted of the endurance shuttle run, Wells sit-and-reach, jump and reach, standing long jump, agility shuttle run and 30-yard dash. Individual, generalized estimating equation models were used to estimate the association between each measure and the odds of participating in high school sport. For both sexes, the endurance shuttle run and agility shuttle run were related to sport participation. For boys only, the long jump and 30-yard dash were also associated with sport participation. Better physical fitness and performance across several dimensions in childhood, including those related to motor skills, enhanced the likelihood of sport participation in high school. 相似文献

This study investigated the impact of an open inquiry experience on elementary science methods students’ understanding of
celestial motion as well as the methods developed by students to answer their own research questions. Pre/post interviews
and assessments were used to measure change in participants’ understanding (N = 18). A qualitative approach was used to describe the nature of each participant’s investigation through an analysis of
their science journal and poster presentations. A comparison of participants’ inquiry projects with the change in their understanding
revealed that while most participants improved in both their area of inquiry and beyond, elementary science methods students
may need more guidance to reach a full scientific understanding across all aspects of celestial motion. 相似文献

You've Been Warned: Does Information About Pitfalls of Technological Toys Affect Caregiver Behavior?
Although the presence of toys in childhood has remained steady for decades, the types of toys that fill children's toy boxes have changed, especially over the last 10–15 years. Many of today's toys are marked by technological enhancements, from a shape sorter driven by a singing bear to robotic plastic animals designed to match a toddler's favorite television show. Although examining the effects of these changes is still an unexplored area, research to date suggests that there may be costs to the quality of caregiver–child interaction when using these toys together. This leads to two possibilities: (1) the design of the enhancements themselves hurt interactions; or (2) these toys can still be beneficial to interactions, but caregivers simply need to be aware of the potential pitfalls. In this study, we explore whether providing caregivers with a subtle cue about the potential negative impacts of technological toys on caregiver–child interaction affects their behavior. 相似文献

This short paper explores the contribution or otherwise that could be made by using a test akin to the American Scholastic Assessment Test or SAT to select students for undergraduate degrees in the UK. It examines the political context to the debate about the potential value of such a test, before outlining how SAT results in America vary along dimensions related to social background and how American universities have adapted their admissions procedures in response to these differences. From the research examined it cannot be assumed that the introduction of a test such as the SAT would be any more equitable then the current use of public examinations in England. It is suggested that profiling students along the lines used by some American universities may assist with making access ‘fairer’. 相似文献

Rebecca Doyle set up the first nurture group in Thetford Education Action Zone in 2000. In 2001, she published an account of her work to reintegrate pupils from the nurture group into the mainstream of their infant school in the pages of BJSE. In this article, Rebecca Doyle describes how mainstream class teachers requested further support in working with socially and emotionally vulnerable children in their classes using the principles and practices from the nurture group. A social development curriculum was written to support this interest, offering mainstream staff a planning tool to complement their existing schemes of work and to help in the drive to make the curriculum appropriate for every child, regardless of their barriers to learning. This article indicates that mainstream staff are now able to bring the increasing knowledge of nurture group working to the fore in their planning, supporting the development of whole-school nurturing approaches. The social development curriculum has become a well-used document alongside current planning frameworks, supporting staff in meeting the diverse needs of pupils within mainstream classrooms with minimal cost and little additional workload.
In closing her article, Rebecca Doyle argues that the social development curriculum has had a positive impact upon the pupils in her school and upon her colleagues on the staff. She is pursuing her research into nurturing approaches through her membership of the National Nurture Group Network and her studies for a higher degree at the University of East Anglia. 相似文献

This study investigated whether haematological markers differ between young and masters marathon participants, running at similar performance levels. Nine young (31.89 ± 4.96 years) and eight masters (63.13 ± 4.61 years) runners participated. At five time points (pre-race through 54 h post-race), a complete blood cell count, basic metabolic panel and creatine kinase (CK) isoenzyme panel were assessed. Race performance was standardised using the World Masters Association Age Grading Performance Tables. Total CK levels were elevated for all participants at all time points post-race (P < 0.001). The CK-isoenzyme MB% was elevated across groups at 6, 30 and 54 h post-race (P < 0.01, P < 0.01 and P < 0.05), with masters runners having a higher CK-MB% at 30 and 54 h (P < 0.05, P < 0.05). Total white blood cell and neutrophil counts were elevated through 6 h post-race (P < 0.001), with higher levels found in younger runners (P < 0.001). When considering all blood work, masters runners had a higher number of abnormal values at 6, 30 and 54 h post-race (P < 0.05, P < 0.01 and P < 0.05). In conclusion, masters runners demonstrated sustained CK-MB elevation, which may suggest greater cardiac stress. However, future studies using additional cardiac markers should be completed to confirm these findings. In addition, masters runners showed an increased number of laboratory values outside normal range, indicating the body’s reduced capacity to respond to marathon running. 相似文献
