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

The responsiveness to change of the Actical and ActiGraph accelerometers was assessed in children and adolescents. Participants (N = 208) aged 6 to 16 years completed two simulated free-living protocols, one with primarily light-to-moderate physical activity (PA) and one with mostly moderate-to-vigorous PA. Time in sedentary, light, moderate, and vigorous PA was estimated using 8 previously developed cut-points (4 for Actical and 4 for ActiGraph) and 5-sec, 15-sec, and 30-sec epochs. Accelerometer responsiveness for detecting differences in PA between protocols was assessed using standardized response means (SRMs). SRM values ≥.8 represented high responsiveness to change. Both accelerometers showed high responsiveness for all PA intensities (SRMs = 1.2–4.7 for Actical and 1.1–3.3 for ActiGraph). All cut-points and epoch lengths yielded high responsiveness, and choice of cut-points and epoch length had little effect on responsiveness. Thus, both the Actical and ActiGraph can detect change in PA in a simulated free-living setting, irrespective of cut-point selection or epoch length.  相似文献

Students need to be challenged to stimulate their learning. Applying challenge in practice however is not straightforward. Challenging students may conflict with other teacher responsibilities, creating potential dilemmas for teachers. This study discloses dilemmas teachers encounter when challenging students as well as the considerations accompanying their actual choices for action when coping with these dilemmas. Based on interviews with teachers, first, a dilemma analysis instrument was developed. Seven main categories of dilemmas were found. One of the main dilemmas encompassed maximizing challenge versus keeping all students on board. University students differ in their ability, confronting teachers with the feeling that choosing to serve one group could be detrimental to the learning of others. The diversity of choices and considerations brought forward by the teachers indicates that it matters who the teacher is, and what he or she stands for and is able to do.  相似文献

Far from all who complete teacher education end up working as teachers throughout their entire career. At first sight the value of teacher education, in terms of efficiency, seems to be a failure. In the present article we argue that teacher attrition, when defined as whether one is working as teacher or not, is a too blunt measure to gauge whether teacher education has been valuable. With a unique dataset, where we have detailed information on 87 Swedish teacher graduates’ working life across 23 years, we can consider whether activities and/or experiences point to an apparent use of teacher education. In conclusion, we find that in order to get informative estimates of its value it is important to consider it from different perspectives and to consider attrition related to the total working time spent in educational settings across a career rather than percentage leaving teaching after a set of years  相似文献

In this study, four recent self-initiated educational quality projects at Swedish universities are compared and analyzed. The article focuses on how the universities have handled the tension between external demands and internal norms. The aim is to contribute to an improved understanding of quality management in contemporary universities. On the one hand, the projects are found to be built on similar rationales associated with accountability, reputation building and strategic management. This is interpreted as a response to the shared external policy context. They are also found to mirror similar ambitions regarding raising the status of education. On the other hand, the projects are found to differ considerably in their actual design, methodology, implementation, stakeholders and outcomes. This is interpreted as an active adaptation to the unique internal academic norms and cultures that exist in each university.  相似文献

Vocational education, as part of the Norwegian upper secondary education, includes both school-based learning and workplace learning. While school-based learning is characterized by formal structures and guided by aims in the curricula, workplace learning is often informal, incidental and directed by the daily work-tasks. Assessment in workplace learning is mainly formative and different stakeholders are involved in the assessment; namely students, teachers and workplace instructors. However, the guidelines for assessment are vague and call for a close cooperation between the stakeholders. This is demanding and has resulted in a variety of assessment practices. The study presented in this article is a qualitative study of students’ experiences with assessment in workplace learning periods in their first year in vocational education. The aim of the study is to give voice to students` experiences with assessment and illuminate how assessment supports their learning processes. Data was collected through focus group interviews with two groups of students in the Programme for Health and Social Care. The main findings indicate different assessment cultures in school and workplaces. This is expressed through the students’ perceptions of assessment, assessment criteria, tools for assessment and vocational knowledge. It is recommended that an open dialogue about the discontinuity in assessment between schools and workplaces is one of several measures necessary to bridge the gap between the stakeholders.  相似文献

In Sweden radio and television programs for educational purposes are produced by a special unit within Sveriges Radio (SR), but there is also a production unit outside the organization SR producing educational programs, in the first place for adults (TRU). In the near future these two units are to be joined into one. In the Educational Program Department of SR there is a special group concerned with research and development questions. For the time being there are four full‐time posts as researchers, and within the framework of the budget of the program department the research group has it's own budget for research and evaluation of radio and television in instruction. The aim of this internal research ‐‐ exemplified in this paper ‐ is to give producers such experience as can be of value both for the assessment of individual products and for production work in the long run.  相似文献

It has been argued that user participation is important when public authorities develop e-services. At the same time there is limited research on the usefulness of existing user participation approaches in public e-service development. In this paper we, therefore, analyze how the three user participation approaches – participatory design, user-centered design, and user innovation – meet the strategic e-service goals of the EU and the US. In doing so, we identify three challenges that need to be considered when choosing among these approaches: 1) unclear user target segments can impede the fulfillment of usability and relevance goals, 2) the nature of participation can impede the fulfillment of democracy goals, and 3) lack of adequate skills can impede the fulfillment of efficiency goals.  相似文献
