Abstract

This study employs the theory of “media logic” and the method of hermeneutical criticism to demonstrate some effects of a major social institution, television, on the “text” of experiencing spectator sports. The study finds that the medium of television makes spectator sports into an experience which incorporates narrative, intimacy, commodification, and rigid time segmentation. The conventions imposed by television on spectator sports are presented here as powerfully affecting the meanings which televised sports have for their audiences.  相似文献

Concerns around the provision and retention of quality teachers are global. Amongst these concerns are the preparedness of graduate teachers and the quality and nature of teacher education. The purpose of the article is to focus questions of teacher preparedness and education within a wider discussion around the professional life-cycle of teachers. Initial teacher education is viewed as the first phase of the professional life-cycle of a teacher; part of a professional continuum of learning and expertise, rather than a distinct preparatory phase. We do not present a detailed model for this continuum; believing there is still significant work to be done on defining and delineating the levels of expertise. Such work is beyond the scope of this paper. We do provide a starting point for further consideration. Further, we suggest a scaffolded transition, determined by the learning needs of teachers, between initial teacher education and induction, moving to in-service learning, with closer connections between providers and schools to mitigate against a disconnect between these phases of development. The potential role of professional standards in supporting teacher learning across the professional life-cycle is also discussed.  相似文献

Relationships between self‐directed learning projects of adults and the directed learning activities comprising a community college curriculum need to be developed and clarified. Learning projects are defined as a series of related episodes where individuals intentionally spend seven or more hours to gain and retain fairly certain knowledge, information or skills. Trained interviewers used a structured interview format to investigate a total of 290 learning projects conducted by 41 males enrolled in a community college. During the 12 months preceeding the interview, subjects completed an average of 7 learning projects, devoting an average of 285 hours to each learning project. The learning projects were self‐directed (56%), for immediate or future use (57%), not motivated by academic credit (79%), acquired information from another person (57%), and resulted in a large amount of knowledge gained (63%). The results suggest that, even when adults are enrolled in a formal academic program, their learning projects are self‐directed, intrinsically motivated, and pragmatically oriented. The findings imply that: (a) procedures to utilize intrinsic motivation could be more widely employed in curricula design; and (b) the teacher of adults would best serve students as a facilitator who guides and supports learning.  相似文献

ABSTRACT

This study determined the physical and technical demands of elite wheelchair tennis (WT) match-play, how the demands differed between divisions (Men, Women, Quad) and the effect that set result and score margin had on these demands. Seventeen WT players were monitored during a singles competition. Physical measures of performance were analysed using an indoor tracking system and inertial measurement units. Technical measures of performance were examined using video analysis. Physical measures of performance differed by division (Men > Women > Quad) for most parameters. Rallies were longer during Men’s (P = 0.027) and Women’s (P = 0.004) matches compared to Quad’s and fewer shots were hit off 2 bounces in Men’s matches compared to Women’s and Quad’s (P ≤ 0.026). High-speed activity (HSA) increased during losing sets (P = 0.043). Most physical measures of performance increased by moderate to large effects during sets with a small score margin (≤3 games differential). Mean speed and HSA were similar during losing sets, regardless of margin, but decreased (large effects) when winning by a large margin. This study demonstrated the physical and technical demands that elite WT players need to be prepared for and how situational factors can influence these demands.  相似文献
