ABSTRACTBackground: Over the past 10 years, research has started to investigate the pedagogic practices of instructors and coaches working in adventure sports settings. Outdoor instructors face particular challenges regarding the impact the dynamic environment has on the coaching process and their students. This challenging combination of factors obliges the instructor to be agile in response. We propose that this adaptive expertise is characteristic of these factors and that adaptability may be a beneficial focus of outdoor instructor training and education.Purpose: The major aim was to identify if adaptive expertise is an attribute of outdoor instructors? And if so, what are its characteristics in this context?Research design and data collection: We applied a mixed methodology to a sample of outdoor instructors (n?=?64). The instructors were asked to complete a quantitative adaptive expertise inventory. We then interviewed a selected sub-sample (n?=?12).Participants and setting: Quantitative data was collected from outdoor instructors working in the UK (n?=?64). The sample consisted of instructors qualified to work independently with groups in adventurous settings in a range of activities. Qualitative data was collected from a smaller sample (n?=?12) via a series of thematically analysed semi-structured interviews.Findings: Results suggest that the participating outdoor instructors have high levels of adaptive expertise. A characteristic of that adaptive capacity is a combination of skills revolving around reflection, metacognition, and situational awareness. There were differences, however, between less and more experienced outdoor instructors in their adaptive capacity, with less experienced instructors being adaptive to a lesser extent.Conclusions: The implication is that further research is worthwhile to examine the development of instructors’ adaptive capacity. The training and education of outdoor instructors requires pedagogic approaches that facilitate and engender adaptability, flexibility and agility in neophyte instructors. 相似文献

ABSTRACT Running is a common exercise with numerous health benefits. Vertical ground reaction force (vGRF) influences running injury risk and running performance. Measurement of vGRF during running is now primarily constrained to a laboratory setting. The purpose of this study was to evaluate a new approach to measuring vGRF during running. This approach can be used outside of the laboratory and involves running shoes instrumented with novel piezoresponsive sensors and a standard accelerometer. Thirty-one individuals ran at three different speeds on a force-instrumented treadmill while wearing the instrumented running shoes. vGRF was predicted using data collected from the instrumented shoes, and predicted vGRF were compared to vGRF measured via the treadmill. Per cent error of the resulting predictions varied depending upon the predicted vGRF characteristic. Per cent error was relatively low for predicted vGRF impulse (2–7%), active peak vGRF (3–7%), and ground contact time (3–6%), but relatively high for predicted vGRF load rates (22–29%). These errors should decrease with future iterations of the instrumented shoes and collection of additional data from a more diverse sample. The novel technology described herein might become a feasible way to collect large amounts of vGRF data outside of the traditional biomechanics laboratory. 相似文献

A comparison of correspondence and Web versions of the same course indicated that, although the students were very satisfied with the Web version, the correspondence section achieved the higher mean final scores in three of the four semesters while the Web course achieved the higher mean score in only one semester. A literature search indicated that there are very few studies which compare the relative successes of Web-based courses and traditional (lecture) courses as this present study does. In addition most of these other comparative studies are based on only one offering of the Web-based course, whereas the present study evaluates the Web-based course over four different semesters. 相似文献

This article continues a theme of previous investigations by the authors and examines the focus of in-action reflection as a component of professional judgement and decision-making (PJDM) processes in high-level adventure sports coaching. We utilised a thematic analysis approach to investigate the decision-making practices of a sample of high-level adventure sports coaches over a series of sessions. It was discovered that adventure sports coaches utilise a combination of questioning and observation to collect and constantly verify the information that forms the basis of their PJDM. Each coach responds to matters of immediate security, collecting information until a best-fit decision can be made regarding changes to the environment, task or individual. Implications for professional training, accreditation and development are presented against these data, offering a template for a more expertise-focused progression in the adventure sports coaching profession. 相似文献

This paper explores the rise of programs in television instruction in the USA during broadcasting’s postwar expansion period. Beginning in professional schools, television training entered the university first through extension school courses, then in full degree programs. This transition to institutions of higher learning entailed key shifts in demographics, pedagogical orientation, and legitimation strategies, while embroiling television in larger struggles over the shifting boundaries of the postwar humanities. Studying the education of early television workers, I argue, raises key questions about processes of worker professionalization vital for developing research on media industries and media labor. 相似文献
