This study supports the important role teacher training programs can play in increasing physical education knowledge. In this project, teachers were able to increase students' understanding of critical physical activity/fitness knowledge through physical education instruction, without changing the physical education contact time. This link to student needs as well as the school's overall mission is a promising one for students and schools alike. 相似文献

Movement patterns and physical strain during a novel, simulated cricket batting innings (BATEX) 总被引:1,自引:1,他引:0
A simulated cricket batting innings was developed to replicate the physical demands of scoring a century during One-Day International cricket. The simulated innings requires running-between-the-wickets across six 5-over stages, each of 21 min duration. To validate whether the simulated batting innings is reflective of One-Day International batting, movement patterns were collected using a global positioning system (GPS) and compared with previous research. In addition, indicators of physical strain were recorded (heart rate, jump heights, sweat loss, tympanic temperature). Nine club cricketers (mean ± s: age 20 ± 3 years; body mass 79.5 ± 7.9 kg) performed the simulated innings outdoors. There was a moderate trend for distance covered in the simulated innings to be less than that during One-Day batting (2171 ± 157 vs. 2476 ± 631 m · h?1; effect size = 0.78). This difference was largely explained by a strong trend for less distance covered walking in the simulated innings than in One-Day batting (1359 ± 157 vs. 1604 ± 438 m · h?1; effect size = 1.61). However, there was a marked trend for distance covered both striding and sprinting to be greater in the simulated innings than in One-Day batting (effect size > 1.2). Practically, the simulated batting innings may be used for match-realistic physical training and as a research protocol to assess the demands of prolonged, high-intensity cricket batting. 相似文献

Schools offer powerful scope for viewing and comprehending the wider society in which they are produced and replicated. The ways in which schools are structured, positioned, funded, managed, appreciated, critiqued, cared for and neglected, presents us with a means for seeing beyond the rhetoric of a nation state to the lived realities faced by its citizens. In this paper I want to link the development of Australian educational policies to shifts in socio-cultural thought and practice that reflect and reproduce a mobile modernity. I am interested in school funding policies as they relate to the private, or non-government education sector from the late colonial period to these so-called neo-liberal/late modern times. The interrogated scenes shift about amongst a complex of interrelated fields, from the urban to the rural, the public and the private, as well as the primary, secondary and tertiary layers of educational “offerings”. The periodization reveals a loosening of commitments to a secular, state-centred, welfare-focused modernity, towards a privatizing, individualizing “second modernity”. Drawing from a range of empirical studies of school choice I highlight the shifting ideas and practices of those involved in the re-production of both public and private schools either as professionals/workers in the system, or as “consumers” of the products available in education’s “quasi-markets”. 相似文献

Science education studies have revealed that students often have misconceptions about how nature works, but what happens to misconceptions after a conceptual change remains poorly understood. Are misconceptions rejected and replaced by scientific conceptions, or are they still present in students' minds, coexisting with newly acquired scientific conceptions? In this study, we use functional magnetic resonance imaging (fMRI) to compare brain activation between novices and experts in science when they evaluate the correctness of simple electric circuits. Results show that experts, more than novices, activate brain areas involved in inhibition when they evaluate electric circuits in which a bulb lights up, even though there is only one wire connecting it to the battery. These findings suggest that experts may still have a misconception encoded in the neural networks of their brains that must be inhibited in order to answer scientifically. 相似文献

Although there has been a great deal of research into Collaborative Information Retrieval (CIR) and Collaborative Information Seeking (CIS), the majority has assumed that team members have the same level of unrestricted access to underlying information. However, observations from different domains (e.g. healthcare, business, etc.) have suggested that collaboration sometimes involves people with differing levels of access to underlying information. This type of scenario has been referred to as Multi-Level Collaborative Information Retrieval (MLCIR). To the best of our knowledge, no studies have been conducted to investigate the effect of awareness, an existing CIR/CIS concept, on MLCIR. To address this gap in current knowledge, we conducted two separate user studies using a total of 5 different collaborative search interfaces and 3 information access scenarios. A number of Information Retrieval (IR), CIS and CIR evaluation metrics, as well as questionnaires were used to compare the interfaces. Design interviews were also conducted after evaluations to obtain qualitative feedback from participants. Results suggested that query properties such as time spent on query, query popularity and query effectiveness could allow users to obtain information about team's search performance and implicitly suggest better queries without disclosing sensitive data. Besides, having access to a history of intersecting viewed, relevant and bookmarked documents could provide similar positive effect as query properties. Also, it was found that being able to easily identify different team members and their actions is important for users in MLCIR. Based on our findings, we provide important design recommendations to help develop new CIR and MLCIR interfaces. 相似文献
