E-portfolios are being introduced into initial teacher education programmes internationally to help pre-service teachers build records of their learning journeys and develop into reflective practitioners; to allow them to assemble collections of evidence of their achievements against graduate standards, which can function as digital CVs; and to facilitate the seeding of personal learning networks that will support lifelong learning after graduation. Despite certain tensions between these aims, the potential benefits of e-portfolios make them an increasingly popular choice in teacher education. In this article, we discuss the introduction of Wi-Fi-based e-portfolios into a Master of Teaching programme at an Australian university. These served primarily as developmental e-portfolios, or personal learning environments (PLEs), and were designed to place particular emphasis on reflective practice. We describe how the e-portfolios were perceived and used by pre-service teachers in the first year of their implementation, and indicate the challenges and limitations encountered. Lessons learnt from the implementation are outlined and recommendations are proposed.  相似文献

The purpose of this study was to analyze how the challenges of urban schools influence physical education teachers' emotional understanding and connections with their students and the implications on their teaching. Sixty-one elementary physical educators from an urban school district in the midwestern U.S. were interviewed multiple times (N = 136) over 3 years using interpretive methodology. Teachers reported five unique challenges that significantly shaped their thinking about students and their careers, along with strategies they used to overcome or manage those challenges. The challenges were: (a) insufficient instructional resources, (b) implementing culturally relevant pedagogy, (c) dealing with community violence, (d) integrating more games in curricula, and (e) teaching in a culture of basketball. Implications centered on the guilt-inducing nature of urban teaching, developing an informed and realistic vision of urban physical education, and the role of teacher preparation and professional development.  相似文献

The digitization of works renders them not only easy to copy and distribute. It makes them easy to transform from one medium to another. Many of the same fair use questions posed by the copying or use of computer programs recur when other kinds of digital data are copied or manipulated. There are some situations in which digital copying would almost certainly be permitted as fair use, and some in which fair use defenses would be futile.

The writer recently spent a year as Visiting Professor of mechanical engineering at Lehigh University, Bethehem, Pa. As a result of this visit and incidental visits to other Universities and laboratories in the U. S. A. and England, some thoughts on engineering education are here set down. First, comparisons are drawn between American and British engineerinig schools, and then analyses of the curricula in civil, electrical and mechanical engineering are made in order to discover the common content. From this emerges a fairly generally accepted common core which may be used as a yardstick or norm and as a starting point for any revision. Interesting educational trends are evident, both in curricula and physical equipment. These are reviewed and suggestions as to the future are made.  相似文献

PurposeThe aim of this study was to evaluate the efficacy of a 17-week, 3-component lifestyle intervention for enhancing health behaviors during the coronavirus disease 2019 (COVID-19) pandemic.MethodsA parallel-group (intervention and control) study was conducted amongst 79 airline pilots over a 17-week period during the COVID-19 pandemic. The intervention group (n = 38) received a personalized sleep, dietary, and physical activity (PA) program. The control group (n = 41) received no intervention. Outcome measures for sleep, fruit and vegetable intake, PA, and subjective health were measured though an online survey before and after the 17-week period. The changes in outcome measures were used to determine the efficacy of the intervention.ResultsSignificant main effects for time × group were found for International Physical Activity Questionnaire-walk (p = 0.02) and for all other outcome measures (p < 0.01). The intervention group significantly improved in sleep duration (p < 0.01; d = 1.35), Pittsburgh Sleep Quality Index score (p < 0.01; d = 1.14), moderate-to-vigorous PA (p < 0.01; d = 1.44), fruit and vegetable intake (p < 0.01; d = 2.09), Short Form 12v2 physical score (p < 0.01; d = 1.52), and Short Form 12v2 mental score (p < 0.01; d = 2.09). The control group showed significant negative change for sleep duration, Pittsburgh Sleep Quality Index score, and Short Form 12v2 mental score (p < 0.01).ConclusionResults provide preliminary evidence that a 3-component healthy sleep, eating, and PA intervention elicit improvements in health behaviors and perceived subjective health in pilots and may improve quality of life during an unprecedented global pandemic.  相似文献

The discursive viewpoint adopted by many researchers who study everyday life information seeking allows for a shift in focus away from the individual as a unit of analysis toward a more general understanding of the broader cultural conditions within which individuals operate. However, the data employed by such researchers often consist of the testimony or observed actions of individuals. This paradox provides a point from which to reflect on the process of gaining access or entry to everyday life information seekers as research participants. This article presents the authors’ reflections on their experiences of conducting separate library and information science studies of three diverse populations: pregnant women, members of a self-help support group, and preschool children. The article’s premise is that theory and research practice are intertwined and that attending to issues of gaining access is essential for the development of both. Access is an emergent process dependent on the characteristics of the researcher, the participants, and the research context.  相似文献

This research is based on an empirical study exploring how academics make curriculum decisions and their perceptions of the influences that shape their decisions. Interviews were held with 20 academics from diverse disciplines, who were both research active and committed to teaching. The higher education curriculum was conceptualised as a field of decision-making shaped by academics’ beliefs about educational and contextual influences. The study identified five distinctive curriculum orientations representing coherent patterns of curriculum decisions aligned with academics’ beliefs about educational purposes. Case studies are presented to elucidate each of the curriculum orientations. Curriculum orientations were also found to shape academics’ responses to educational change. The following higher education change drivers are explored: graduate employability and the skills agenda, teaching–research relationships, changing understandings about teaching and learning, educational technologies and flexible delivery. The findings suggest implications for institutional curriculum change initiatives and academic development programmes.  相似文献
