Usually, in physics textbooks, the physical magnitude ‘work’ is introduced as the product of a force multiplied by its displacement, in relation to the transfer of energy. In other words, ‘work’ is presented as an internal affair of physics theory, while its relation to the world of experience, that is its empirical meaning, is missing. On the other hand, in the history of its creation, ‘work’ was a concept that had empirical meaning from the start. It was constructed by engineers to measure the work (labor) of motor engines, men, and animals. Very soon however this initial meaning seems to vanish. In this article, it will be looked at how ‘work’ is presented in physics textbooks, what was its initial meaning in the history of its formulation, under what circumstances this initial meaning faded, and how elements from the history of its creation can be used in the classroom to teach it. 相似文献

Mind-body dualism has likely influenced how many view human beings and their behavior—mind (i.e., thinking) is elevated over body (i.e., performing)—even in Physical Education Teacher Education. The problem is that such a perspective makes physical education content (i.e., dance, games, play, and sport) subsidiary to more “intellectual” or “academic” content. This article invites Physical Education Teacher Education faculty to consider how to effectively “send the message” to future physical educators that physical education content is valuable and respectable and in many ways epitomizes intelligent human behavior. Specifically, Physical Education Teacher Education faculty are invited to (a) challenge traditional definitions of intelligence and introduce alternative definitions, (b) participate regularly in their own playgrounds, (c) provide a sufficient dose of activity courses in their curricula, (d) teach activity courses, (e) establish a performance-oriented culture, and (f) administer performance and/or game play evaluations. 相似文献

The purpose of this study was to assess the validity and reliability of the Physical Educators’ Judgments about Inclusion (PEJI) survey for analysing the judgments of Japanese (361 male, 170 female) physical education teacher education majors. A secondary purpose was to examine group differences in judgments as a function of gender and past experiences. Data were collected and psychometrical properties of the PEJI were assessed using a maximum-likelihood extraction method. Confirmatory factor analysis resulted in salient loadings for all items on three hypothesised dimensions, resulting in 47% explained variance for measuring judgments about: Inclusion versus Exclusion, Acceptance of Students with Disabilities, and Perceived Training Needs. Supported by the three interpretable factors that emerged, construct validity evidence is presented. Although most of the physical education teacher education majors sampled had yet to teach students with disabilities, they had formed preliminary judgments about doing so. 相似文献

Floorplan, clock network and power plan are crucial steps in deep sub-micron system-on-chip design. A novel di- agonal floorplan is integrated to enhance the data sharing between different cores in system-on-chip. Custom clock network con- taining hand-adjusted buffers and variable routing rules is constructed to realize balanced synchronization. Effective power plan considering both IR drop and electromigration achieves high utilization and maintains power integrity in our MediaSoC. Using such methods, deep sub-micron design challenges are managed under a fast prototyping methodology, which greatly shortens the design cycle. 相似文献

The authors of this paper compared the views of Slovenian and Portuguese preschool teachers about the importance of play and movement for the preschool children. In the paper, they focused on the question： Does physical activity of preschool teachers （spontaneous or planned） impact the planning and implementation of movement activities in their kindergarten group？ They also analyzed the influence of subjective theories on the planning of movement activities and the realization of the curriculum objectives in the field of movement. Most of the preschool teachers in Slovenia and Portugal give priority to natural forms of movement in nature and play, allowing the movement of the fingers, palms, and hands. Research has shown a link between physical activity of preschool teachers and their views on the importance of the implementation of the movement activities of preschool children. The authors also noted that the quality of the implementation of the education process in kindergartens in the area of movement activities depends on their subjective theories to a great extent and on the level of professional competence referred to the discussed topic. 相似文献

Physical learning, cognitive learning, social learning, and affective learning are positioned as the legitimate learning outcomes of physical education. It has been argued that these four learning outcomes go toward facilitating students’ engagement with the physically active life (Bailey et al., 2009; Kirk, 2013). With Cooperative Learning positioned as a pedagogical model capable of supporting these four learning outcomes (Dyson & Casey, 2012), the purpose of this review was to explore the empirical research in the use of Cooperative Learning in physical education reported on the achievement of learning in the physical, cognitive, social, and affective domains (or their equivalents). The review found that while learning occurred in all 4 domains, the predominant outcomes were reported in the physical, cognitive, and social domains. Affective learning was reported anecdotally, and it became clear that more work is required in this area. The article concludes by suggesting that research into the outcomes of this and other pedagogical models needs to focus on learning beyond the initial instructional unit and extend over a period of years and not just weeks. 相似文献

This paper explores final-year physical sciences preservice teachers’ religious and scientific views regarding the origin of the universe and life. Data was obtained from 10 preservice teachers from individual in-depth interviews conducted at the end of the Science Method module. Their viewpoints were analyzed using coding, sorting, and categorizing. They attributed the origin of the universe and life to a blend of theistic, intelligent design or scientific beliefs. Moreover, their academic backgrounds, exposure to topics in Cosmology in the Science Method module, and classroom dialogues did not significantly influence or change their original religious beliefs. However, the dialogues did create an awareness of their own reflected positions regarding the tenacity of beliefs in religion and their inadequate cosmological understandings. The paper has implications for Science Education in addressing preservice teachers’ religious beliefs in contrast to scientific evidence. 相似文献

While decades of research have documented the socialization of inservice physical education teachers, the socialization of physical education faculty members has only recently become a research focus. Self-study of teacher education practices is becoming increasingly popular when exploring the lived experiences of physical education faculty. We used self-study of teacher education practices to understand the experiences of Kevin, a beginning physical education teacher educator in a visiting assistant professor position at Northern Illinois University. Kevin’s experiences differ from those of many other teacher educators as he had not taught in school settings before moving into higher education. He did, however, have a strong background in higher education pedagogy through work in a center for teaching and learning. Data were collected through journaling, documents and artifacts, and exit slips, feedback forms, and focus group interviews completed by Kevin’s students. Qualitative data analyses resulted in the construction of three first-order themes: (1) developing appropriate pedagogy, (2) developing and maintaining relationships with students, and (3) managing an identity as a teacher educator. Kevin’s journey was non-linear and marked by both successes and challenges, but at the end of the year he felt that he had grown as a teacher educator. Further, while Kevin’s youth and lack of teaching experience influenced his teacher education practice, it was not always negative and he found ways to compensate for what he lacked in direct teaching experience. Results are discussed with reference to Kevin’s socialization and future directions for research are provided. 相似文献

Every living thing has a physical boundary that separates it from its ex-ternal environment. Beginning with the bacteria(细菌) and the simple cell and ending with man, every organism has a certain limit which marks where it begins and ends.Anyone who has had experience with dogs, particularly in the country-side such as on farms, is familiar with the way in which the dog handles space. In the first place, the dog knows the limits of his master蒺s “yard”and will defend it against encroachmen… 相似文献

Similarities and differences were examined in the out‐of‐school recreation and leisure activity participation of 422 children with physical disabilities and 354 children without disabilities. The roles of age (six to eight years, nine to 11 years, and 12–14 years), gender, and disability status were examined with respect to the diversity, intensity, location, companionship, and enjoyment of participation in five types of activities, controlling for family income. The findings indicate that dimensions and types of activity participation are differentially influenced by age, gender, and disability. Age cohort comparisons indicated that children without disabilities experienced a widening social world characterised by more intense social participation, greater participation with non‐family members, and stable levels of enjoyment across the age groups. In contrast, children with disabilities in the various age groups were similar in their intensity of social participation and the nature of their companionship, with 12–14 year olds reporting less enjoyment of social activities than those aged six to eight years or nine to 11 years. The findings support the utility of a developmental and contextual perspective in understanding children’s patterns of participation. The information can be used by service providers and managers interested in creating centre‐based or community‐based recreational opportunities, and in providing information to parents about how to encourage children’s recreation and leisure participation. 相似文献

Abstract This article will derive a definition and account of the physically educated person, through an examination of the philosophy of Andrew Reid, Richard Peters and Aristotle. Initially, Reid’s interpretation of Peters’ views about the educational significance of practical knowledge (and physical education) will be considered. While it will be acknowledged that Peters was rather disparaging about the educational merit of some practical activities in Ethics and Education, it will be argued that he elsewhere suggests that such practical activities could be educationally worthwhile in and of themselves. In Education and the educated man he specified that practical activities should be regarded as educationally important if they are either transformed by theoretical understanding and/or pursued to the point of excellence. In suggesting that education involves the cultivation of both theoretical and practical human excellences it is argued that Peters’ philosophy of education begins to take on a more Aristotelian bent. After exploring Aristotle’s notion of virtue (human excellence) and his discussion of physical training in The politics, it is claimed that physical education activities might be most worthwhile when they extend the moral habits and/or modes of thought of pupils, towards excellence. It is concluded that physically educated persons should be defined as those who have learned to arrange their lives in such a way that the physical activities they freely engage in make a distinctive contribution to their long-term flourishing. 相似文献

Abstract The increasing demand on nurses to adopt the roles and responsibilities of full professional status have been reflected in nurse training by the move into higher education. However, while there are undoubted benefits to this move, the authors believe that it has been at the expense of student involvement in their courses and a widening of the gap between theory and practice. This paper presents three strategies for addressing those problems. Firstly, the authors argue for a student‐centred humanistic approach to education within the constraints of a curriculum for professional training. Secondly, they present a strategy for narrowing the theory practice gap through the use of reflective practice. Finally, they outline an approach to continuous and ongoing course evaluation in which findings are immediately applied to produce a flexible and responsive curriculum. The paper concludes by arguing that this broad approach could be successfully employed in any professional training within the further and higher education framework. 相似文献

The understanding of measurement is related to the understanding of the nature of science—one of the main goals of current international science teaching at all levels of education. This case study explores how a first-year university physics course deals with measurement uncertainties in the light of an epistemological analysis of measurement. The data consist of the course documents, interviews with senior instructors, and laboratory instructors’ responses to an online questionnaire. During laboratory work, uncertainties are expressed in the large majority of the measurements made by the students but only in less than half of their calculation results. The instructors’ expectations are that students systematically estimate uncertainties so that they become aware that measurements and calculations are never exact. However, since uncertainties are not specified for the values given in the laboratory guides, uncertainties are often missing from the results of students’ calculations. The potential side effects of students’ measurement understanding are discussed and suggestions for improvements are proposed. 相似文献

Fitnessgram® is a digital platform designed to help physical education teachers measure, record, disseminate and analyse the results of school-based student fitness testing. Despite important questions about the ethics, educational value and costs of Fitnessgram®, it is now widely used in the United States and is spreading to other countries. In this empirically investigative study, we draw on academic studies and commentary, media stories, government and funding body reports, press releases and advertisements to describe the emergence of Fitnessgram® and the convergence of factors that appear to guarantee the programme’s increasing ubiquity. We also discuss the various ways the data sets built by Fitnessgram® may reshape the practice and purpose of physical education as well how young people understand their own health in light of this. In the face of puzzling academic silence on the Fitnessgram® phenomena, this paper stimulates lines of critical academic enquiry about the financial self-interest, educational shortcomings and policy implications that its rise suggests. 相似文献
