In this study, we investigated the effect of ingesting carbohydrate alone or carbohydrate with protein on functional and metabolic markers of recovery from a rugby union-specific shuttle running protocol. On three occasions, at least one week apart in a counterbalanced order, nine experienced male rugby union forwards ingested placebo, carbohydrate (1.2 g · kg body mass(-1) · h(-1)) or carbohydrate with protein (0.4 g · kg body mass(-1) · h(-1)) before, during, and after a rugby union-specific protocol. Markers of muscle damage (creatine kinase: before, 258 ± 171 U · L(-1) vs. 24 h after, 574 ± 285 U · L(-1); myoglobin: pre, 50 ± 18 vs. immediately after, 210 ± 84 nmol · L(-1); P < 0.05) and muscle soreness (1, 2, and 3 [maximum soreness = 8] for before, immediately after, and 24 h after exercise, respectively) increased. Leg strength and repeated 6-s cycle sprint mean power were slightly reduced after exercise (93% and 95% of pre-exercise values, respectively; P < 0.05), but were almost fully recovered after 24 h (97% and 99% of pre-exercise values, respectively). There were no differences between trials for any measure. These results indicate that in experienced rugby players, the small degree of muscle damage and reduction in function induced by the exercise protocol were not attenuated by the ingestion of carbohydrate and protein. 相似文献

Teachers play an important part in identifying child maltreatment but find dealing with it difficult. This study examines the problems involved with evaluating a countywide training programme on this topic for senior teachers. The course was run 17 times and 60% of the participants attending were sent an evaluation questionnaire three months after taking part. There was a 49% response rate. It was found that the activities undertaken by the participants after the course were a greater reflection of the effort required than of the effectiveness of the course. It is argued that this factor should be taken into account when conducting and interpreting any course evaluation. 相似文献

The School of Health and Related Research (ScHARR) at The University of Sheffield run an innovative series of informal 20‐minute Bite Size sessions to help staff and students teach, research, collaborate and communicate more effectively. The sessions have two clear strands: one focused on teaching and the other on research. The remit is not to teach people how to use something in their work or study, but to let them know why they should use it and how they can employ it. By introducing participants to the possibilities and how they can apply ideas and technologies in their work and study in an enthusiastic manner, it is possible to send them away with at least the intention to explore and experiment. The evidence shows that this organic approach is working – staff and students are starting to use many of the tools that Bite Size has covered. Any kind of widespread change within organisations can be hard to deliver, but by bringing champions on your side and delivering sessions in a convenient, informal and timely manner; good practice and ideas can spread naturally.

In this paper, we discuss the anomaly between the increasing interest in feedback in current education research, the continued role of time-limited, unseen examinations as a form of assessment and the dearth of literature on feedback related to such exams. We argue that while exams have long been regarded as different from other forms of assessment, it is not justifiable to exempt them from the good practice that can, and does, inform these other types of assessment. We suggest a solution to providing timely, effective feedback for end of course examinations is to move the feedback emphasis to ‘feedforward’ by implementing exemplars (examples of real students’ work, generally of different qualities). This study adopts a mixed-methods approach to investigate whether there was a relationship between student use of exemplars before the exam and the final exam grade achieved (n?=?520), and to explore students’ and lecturers’ perspectives about the effectiveness of and engagement with exemplars. Quantitative findings suggested that those students who accessed exemplars did score better in their exams than those that did not. Qualitative data revealed that exemplars were received positively by students and lecturers, and we use this to provide practical suggestions on exemplar good practice. 相似文献

This paper outlines the characteristics of peer mediation in schools and its potential, evident in the literature, for reducing pupil–pupil conflicts referred to teachers. Then, drawing on personal experience, research and a review of literature, the author argues that for peer mediation projects to be effective they need to be in synergy with the culture of the school, including its approach and vision to the management of conflict. Making this argument requires a means of modelling school culture, which will be outlined. Finally, the author argues that attention also needs to be given to how the service will be sustained. 相似文献

In this article UK governmental policy imperatives to apply new forms of information and communications technology (ICT) to school improvement are explored, with particular reference to the National Curriculum for England and Wales. The analysis juxtaposes the piecemeal, random way in which ICT is used in National Curriculum programmes of study and schemes of work with the government rhetoric that requires coherent planning and integration of ICT within all aspects of teaching learning. The article argues that this contradiction within the policy process could be overcome if a stronger conceptualization of teachers' professional knowledge was embraced. An example of such a conceptualization is presented and this is exemplified by accounts of teachers' development of ICT within their pedagogic practice. 相似文献

There is a considerable lack of literature on international student athletes despite the extent to which colleges and universities are increasingly relying on them to heighten the winning reputation of their sports programs. This research focuses on international student athletes from Africa. Based on interviews of 16 student athletes from seven different African countries, the range of their experiences upon entering universities in the United States, particularly their challenges, were identified. Many of the serious issues affecting the student athletes were matters related to the host environment's underestimations about the African student athletes’ desires to learn, misunderstandings about their culture and religions and other negative assumptions that undermined their academic success. We also found that the vast majority of these student athletes experienced negative stereotypes and discrimination based on their race and their region of origin. 相似文献
