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

Dewey continues to offer arguments that remain powerful on the need to break down the divisions between ‘academic’ and ‘vocational’ in terms of his specific theory of knowledge. Dewey's writings are used to argue that a democratic curriculum needs to challenge such divisions to encompass the many forms of knowledge necessary in the contemporary classroom. Gandin and Apple's investigation of community participation (Orçamento Participativo or Participatory Budgeting) in the curriculum of the Citizen School in Porto Alegre, Brazil, will be explored as an example of democratic structures informing educational planning. The work of Paul Hirst, Atli Har?arson and Chris Jane Brough is analysed regarding the issue of curriculum aims and student negotiation. Dewey's emphasis on learning as a collective enterprise will resonate here. Brough offers innovative research on student‐centred curriculum integration that suggests even very young children are able to participate in debate over their own learning. Hirst and Har?arson provide contrasting views on the issue of curriculum aims—Hirst arguing that a curriculum cannot exist without definable aims while Har?arson challenges the very notion of settled aims if students are to be reflexive regarding their education. The article also refers to the work of Alexander on the use of dialogic questioning in the classroom. Such questioning, it is suggested, enhances and encourages collaborative forms of enquiry necessary for a democratic curriculum through discussion between teachers, students and other stakeholders.  相似文献

With the rise of microfluidics for the past decade, there has come an ever more pressing need for a low-cost and rapid prototyping technology, especially for research and education purposes. In this article, we report a rapid prototyping process of chromed masks for various microfluidic applications. The process takes place out of a clean room, uses a commercially available video-projector, and can be completed in less than half an hour. We quantify the ranges of fields of view and of resolutions accessible through this video-projection system and report the fabrication of critical microfluidic components (junctions, straight channels, and curved channels). To exemplify the process, three common devices are produced using this method: a droplet generation device, a gradient generation device, and a neuro-engineering oriented device. The neuro-engineering oriented device is a compartmentalized microfluidic chip, and therefore, required the production and the precise alignment of two different masks.  相似文献

赋权少数族裔学生:一个干预框架   总被引:1,自引:0,他引:1  
吉姆康明斯提出了一个理论框架来分析少数族裔学生学业失败的原因,以及之前曾尝试过的,诸如补偿教育和双语教育这样的教育改革相对缺乏成功的原因。这些尝试之所以没有成功是因为教育者和少数族裔学生之间的关系以及学校和少数族裔社区的关系都没有得到显著的改变。研究旨在为教育者提供一些改变这些关系,从而赋权学生,使得学生在学业上取得成功的方法。  相似文献

Families immigrating to Australia face many challenges integrating into the educational system, including language barriers and interrupted schooling. We have qualitatively evaluated the educational concerns of Arabic migrants from Sudan and Iraq to Melbourne, Victoria, Australia, a city that receives a high percentage of Australia's immigrants. Using an interactive paradigm incorporating focus group discussions for thematic analysis, we concluded that the parents’ frame of reference for education was a more didactic style of learning. Parents viewed education as an essential part of the way forward for their children in Australia. However, it was stressful for them to try to cope with a new host nation's expectation of their involvement in their children's education while at the same time dealing with a language barrier. Professionals should look to empower parents with structural information about the key elements of the educational curriculum with minimal reliance on written technical language and match their expectations of parental involvement to the situation of the parents.  相似文献

Growing numbers of pupils with autistic spectrum disorders (ASD) are attending mainstream schools, and increasing numbers of additional staff are being deployed to support them. Recent research has cast doubt on the effectiveness of this support, by highlighting issues relating to deployment and training, and to relationships with class teachers. This study, conducted by Wendy Symes, who is a Research Associate at the University of Manchester, and Neil Humphrey, who is Professor of Education in the same university, interviewed 15 teaching assistants supporting pupils with ASD in four mainstream secondary schools in the north‐west of England to explore these issues. Analysis yielded several key findings. The majority of teaching assistants worked with just one pupil at a time and worked in a variety of lessons. Their role primarily involved helping pupils to stay focused and follow instructions. Many teaching assistants had no experience of ASD prior to starting their job. The amount of training received varied, but all felt that generic training about ASD was not helpful. A lack of time for joint planning with teachers was raised as a key concern. These findings are discussed in relation to the growing literature on inclusive education for pupils with ASD.  相似文献

Neuroanatomy education is a challenging field which could benefit from modern innovations, such as augmented reality (AR) applications. This study investigates the differences on test scores, cognitive load, and motivation after neuroanatomy learning using AR applications or using cross-sections of the brain. Prior to two practical assignments, a pretest (extended matching questions, double-choice questions and a test on cross-sectional anatomy) and a mental rotation test (MRT) were completed. Sex and MRT scores were used to stratify students over the two groups. The two practical assignments were designed to study (1) general brain anatomy and (2) subcortical structures. Subsequently, participants completed a posttest similar to the pretest and a motivational questionnaire. Finally, a focus group interview was conducted to appraise participants’ perceptions. Medical and biomedical students (n = 31); 19 males (61.3%) and 12 females (38.7%), mean age 19.2 ± 1.7 years participated in this experiment. Students who worked with cross-sections (n = 16) showed significantly more improvement on test scores than students who worked with GreyMapp-AR (P = 0.035) (n = 15). Further analysis showed that this difference was primarily caused by significant improvement on the cross-sectional questions. Students in the cross-section group, moreover, experienced a significantly higher germane (P = 0.009) and extraneous cognitive load (P = 0.016) than students in the GreyMapp-AR group. No significant differences were found in motivational scores. To conclude, this study suggests that AR applications can play a role in future anatomy education as an add-on educational tool, especially in learning three-dimensional relations of anatomical structures.  相似文献
