The cadence that maximises power output developed at the crank by an individual cyclist is conventionally determined using a laboratory test. The purpose of this study was two-fold: (i) to show that such a cadence, which we call the optimal cadence, can be determined using power output, heart-rate, and cadence measured in the field and (ii) to describe methodology to do so. For an individual cyclist's sessions, power output is related to cadence and the elicited heart-rate using a non-linear regression model. Optimal cadences are found for two riders (83 and 70 revolutions per minute, respectively); these cadences are similar to the riders’ preferred cadences (82–92?rpm and 65–75?rpm). Power output reduces by approximately 6% for cadences 20?rpm above or below optimum. Our methodology can be used by a rider to determine an optimal cadence without laboratory testing intervention: the rider will need to collect power output, heart-rate, and cadence measurements from training and racing sessions over an extended period (>6 months); ride at a range of cadences within those sessions; and calculate his/her optimal cadence using the methodology described or a software tool that implements it. 相似文献

The aim of the present study was to investigate the relationships between the three dimensions of transactive memory (coordination, credibility, and specialization) and performance of collaborating students. A total of 113 students, distributed into groups of two or three, participated in the study. They were required to complete a series of learning tasks during the semester and to write a joint report for each task to be evaluated by their instructors. Afterwards, they were asked to fill out a questionnaire including self-report measures of transactive memory. The results showed a well-established positive relationship between transactive memory and performance based essentially on coordination; also, performance improved linearly as members developed specializations within groups. Implications for future research in collaborative learning are discussed. 相似文献

Abstract An NHS Trust set up groups to teach social skills to children and adolescents using a cognitive behavioural framework. One group of seven children (five boys and two girls) is described. Parents were invited to a parallel parents' group. Each group lasted for 90 minutes and ran weekly for 6 weeks. Extensive liaison with parents and teachers took place before, during and after the group. Analysis of pre- and postgroup questionnaires sent to parents and teachers indicated improved social functioning, outside the group, for most of the children. Parents valued the dialogue with professionals and often felt supported by them for the first time. Therapists' contact with teachers ensured full knowledge of children's behaviour and the transfer of skills to schools. Cognitive behavioural techniques with children under-going group work require intensive liaison to facilitate generalization of skills learnt. 相似文献

In the Grow Your Own Teacher (GYOT) program, an initiative developed by a university located on Long Island, New York, and funded by a congressionally-directed grant, a diverse cohort of 11th grade low-income students were financially, academically, and emotionally supported in their goal of becoming math or science teachers in predominantly high needs local school districts. In this article, the formation and solidifying of the developmental relationships, which underscored this intensified mentoring effort, were examined. Throughout the selection and implementation phases of the GYOT program, data were collected from multiple sources from both the secondary and post-secondary levels and analyzed to illuminate the organizational structures, activities, and techniques, the relationship-building elements, which enabled these students to flourish and successfully address personal challenges in acquiring a college degree. 相似文献

This article puts forward a project approach and a set of solutions to better prepare foreign students wishing to enter engineering schools in France. It focuses on how we train students to understand scientific presentations through intensive listening comprehension. Within this framework, it proposes a new educational ICT model that is original from both a pedagogical and a technical point of view. This model was achieved as a result of close collaboration between experts in the fields of science, linguistics, intercultural relations and educational ICT. 相似文献
