Effects of video-feedback on improvement of the tennis service were investigated in subjects having at least 2 years of playing experience in tennis. The experiment was carried out in an indoor tennis hall under normal training conditions. Subjects were randomly divided into three groups: a video-feedback training (VFT) group, a traditional training (TT) group and a control group, each consisting of 22 subjects. While the subjects of the control group received no training at all, subjects in both the VFT and TT groups were trained twice weekly during 5 consecutive weeks. Each training session lasted 40 min, of which 30 min was spent on actual practice in training of the service. The remaining 10 min was spent on watching, analysing and discussing video recordings of either their own service performed during the training session (VFT group), or ground strokes and volleys of top level players (TT group). Both the VFT and TT group showed significantly greater improvements in both achievement scores and form (technique) scores than did the control group. No differences, however, could be demonstrated between the VFT and TT group, indicating that the subjects of the former group did not benefit from the video-feedback they received. While form scores correlated significantly (P less than 0.001) with the velocity of the served ball, no such relation between form scores and spatial accuracy was apparent.  相似文献

Outsourcing is a complex, controversial and pervasive practice that is increasingly becoming a matter of concern for educational researchers. This article contributes to this literature by examining outsourcing practices related to health, sport and physical education (HSPE). Specifically, it reports data on specialist health and physical education (HPE) teachers', principals' and external providers' reasons for participating in outsourcing arrangements. These data were obtained from a collective case study of six schools and the external providers that they outsourced HSPE to over a 12-month period, using semi-structured interviews and overt participant observations. The findings illustrate the ways in which the informants explained their outsourcing practices using a variety of educationally and organisationally oriented reasons. Educational value, human resources (e.g. expertise), physical resources (e.g. facilities) and symbolic resources (e.g. status) were reasons for outsourcing HSPE that were commonly cited by principals and specialist HPE teachers. Among external providers, educational value, income generation and promotion/advertising were frequently cited to explain their work with and for schools. These findings illustrate the ways in which outsourcing practices in HSPE articulate with, and are implicated in, broader educational privatisations. They also highlight the boundaries that outsourcing practices trouble or reinforce, such as those marking the purview of markets, membership of the HPE profession and the constitution of expertise.  相似文献

The availability of reliable evidence for teaching practices after professional development is limited across science, technology, engineering, and mathematics disciplines, making the identification of professional development “best practices” and effective models for change difficult. We aimed to determine the extent to which postdoctoral fellows (i.e., future biology faculty) believed in and implemented evidence-based pedagogies after completion of a 2-yr professional development program, Faculty Institutes for Reforming Science Teaching (FIRST IV). Postdocs (PDs) attended a 2-yr training program during which they completed self-report assessments of their beliefs about teaching and gains in pedagogical knowledge and experience, and they provided copies of class assessments and video recordings of their teaching. The PDs reported greater use of learner-centered compared with teacher-centered strategies. These data were consistent with the results of expert reviews of teaching videos. The majority of PDs (86%) received video ratings that documented active engagement of students and implementation of learner-centered classrooms. Despite practice of higher-level cognition in class sessions, the items used by the PDs on their assessments of learning focused on lower-level cognitive skills. We attributed the high success of the FIRST IV program to our focus on inexperienced teachers, an iterative process of teaching practice and reflection, and development of and teaching a full course.  相似文献

Dissent and assent contribute to new information and knowledge in that they foster ideas, avert errors and counter misplaced beliefs. Although intended to facilitate progress, innovation and creativity, dissent may be opposed by the closed mind and defensive mindset. Don Lamberton encountered a specific mindset in his own duties to scholarship in economics. Thus, the perspective of dissent is a fitting way to pay homage to his scholarship. However, this paper is also a lament. It gives an interpretation of Antigone from political philosophy which depicts Antigone rocking an ideological boat harboured by the polis. The silencing of Antigone’s voice results in unexpected losses in the oikos. This is the sort of tragedy threatening critical and innovative scholarship in the twenty-first century.  相似文献

Teaching the introductory LIS management course may be the most challenging assignment for LIS professors because of the breadth of the subject, the probabilistic nature of management principles, and the differing management environments of LIS organizations. The best teaching strategy is to describe honestly to students the benefits and limitations of the course and to focus on the achievable objectives of introducing students to core management concepts, providing skill enhancement, and encouraging them to evaluate their management potential. The article discusses the difficulties of teaching leadership skills, the limits imposed by student competencies, and the impact of the professor's background on course content.  相似文献
