The analysis of sport performance in competitive contexts has become synonymous with the use of a range of software applications and hardware e.g. heart rate monitors and gps systems. With the prevalence of technology in mind, a small but growing corpus of literature has begun to consider this phenomenon and its influence upon the coaching process. This study adds to this literature by detailing the autoethnographic experiences of a case study coach; Derek. A contextualised and richly described narrative account of Derek’s experience of using coaching applications is provided. Analysis of Derek’s narrative suggests that technology can be a useful means by which individuals make sense of their experience. Specifically, (1) technology can be a ‘ready-to-hand’ instrument that enhances the coaching process. Unfortunately, (2) technology may become the only and ‘calculative’ means by which individuals come to understand their performance. In such instances, it is important to note that (3) the videos we use to understand our performance are transformed and incomplete representations of lived athletic experiences. Thus, Derek’s story illustrates how technology can be both an enabler and barrier to athletes who wish to holistically understand their own lived experiences and engage in coach-athlete relationships. The accompanying analysis draws upon concepts from Heideggerian philosophy to add insight into the use of technology within the coaching process. In so doing, the study prompts coaches to critically view their coach-athlete relationships as situated in a wider world which contains, and can be mediated by, technology. In addition, Derek’s story (re)directs researchers and coaching practitioners interested in technology to a useful literature (philosophy of technology) which may further inform their understanding of coach-athlete relationships. 相似文献

通过对湖南中医药大学非英语专业学生的两篇习作的研究表明:在纠正学生写作中所犯的逻辑错误方面,相比教师反馈,同级反馈效度低。因此,教师在对学生习作进行反馈时,尤其要指出学生逻辑思维方面的漏洞,以提高他们的逻辑思维能力,从而从根本上提高学生的写作应用能力。 相似文献

Atmospheric carbon dioxide concentration [CO2], incoming solar radiation and sea ice coverage are among the most important factors that control the global climate. By applying the simple cell-to-cell mapping technique to a simplified atmosphere-ocean-sea ice feedback climate model, effects of these factors on the stability of the climatic system are studied. The current climatic system is found to be stable but highly nonlinear. The resiliency of stability increases with [CO2] to a summit when [CO2] reaches 290 μL/L which is comparable to the pre-industrial level, suggesting carbon dioxide is essential to the stability of the global climate. With [CO2] rising further, the global climate stability decreases, the mean ocean temperature goes up and the sea ice coverage shrinks in the polar region. When the incoming solar radiation is intensified, the ice coverage gradually diminishes, but the mean ocean temperature remains relatively constant. Overall, our analysis suggests that at the current levels of three external factors the stability of global climate is highly resilient. However, there exists a possibility of extreme states of climate, such as a snow-ball earth and an ice-free earth. 相似文献

Reflective peer coaching is a formative model for improving teaching and learning by examining intentions prior to teaching, then reflecting upon the experience. The goal of reflective peer coaching is to promote self-assessment and collaboration for better teaching and ultimately better learning. There are obvious benefits to colleagues collaborating and sharing ideas, thoughts, and observations. However, many models of assessing teaching effectiveness focus on summative evaluation in which colleagues observe each other once or twice a year and fill out institutional evaluation forms. Rarely do colleagues engage in formative conversations about teaching that are guided by the instructor's personal goals and objectives. Reflective peer coaching necessitates a ten-minute planning conversation prior to the actual lesson and a ten-minute reflective conversation after the lesson. These conversations happen regularly and frequently to build self-awareness and self-assessment of the personal craft of teaching. The following article outlines the dynamics of the reflective peer coaching process as a formative assessment model that leads to better learning through improved teaching. 相似文献

铅球飞行参数即时反馈系统的研制 总被引:2,自引:0,他引:2
"铅球飞行参数即时反馈系统"利用减影技术,用两个CCD窄缝像机,对铅球飞行轨迹上的两个点的高度与时间实现了实时检测。在给定出手高度的条件下,计算机分别计算出铅球的出手角度、出手速度、最佳出手角度等飞行参数,然后提供一个角度大于或偏于最佳出手角的反馈信息。下一次投掷时,系统能够根据上一次投掷的情况给运动员提供一个建议,即出手角度应该高一点或低一点。实验研究表明,该系统能够做到实时检测、实时反馈,是一台运动员技术训练的理想辅助器材,该设备尤其适合于具有较高水平的铅球运动员。 相似文献
