The colour of sportswear has been shown to influence the outcome of bouts for several different combat sports. The generality of these effects, and whether they extend to collaborative forms of contests (team sports), is uncertain. Since 1947, English football teams wearing red shirts have been champions more often than expected on the basis of the proportion of clubs playing in red. To investigate whether this indicates an enhancement of long-term performance in red-wearing teams, we analysed the relative league positions of teams wearing different hues. Across all league divisions, red teams had the best home record, with significant differences in both percentage of maximum points achieved and mean position in the home league table. The effects were not due simply to a difference between teams playing in a colour and those playing in a predominantly white uniform, as the latter performed better than teams in yellow hues. No significant differences were found for performance in matches away from home, when teams commonly do not wear their "home" colours. A matched-pairs analysis of red and non-red wearing teams in eight English cities shows significantly better performance of red teams over a 55-year period. These effects on long-term success have consequences for colour selection in team sports, confirm that wearing red enhances performance in a variety of competitive contexts, and provide further impetus for studies of the mechanisms underlying these effects. 相似文献

There is now considerable support in the higher education literature for research-informed teaching as a means of improving student learning, particularly where this involves students as co-investigators. Such an approach, however, comes with a number of risks that have received little pedagogic attention. This paper addresses that knowledge gap by advocating a novel approach to research-informed teaching which adopts a risk-management philosophy. We review the literature surrounding the challenges of this style of teaching and identify why a risk-management approach might be appropriate to address some of the inherent issues of research-informed teaching previously reported. Our findings indicate a range of potential risks associated with either the delivery, or non-delivery, of research-informed teaching. We offer a broad framework categorising these risks. Forming the basis of a wider risk-management approach, this framework could promote increased reflection and enhancement of teaching practice. 相似文献

This paper reports the findings of a small‐scale study that investigated student nurses’ use of an online resource in Biology. The think‐aloud method was used to explore in detail the ways in which students engaged with this resource and to evaluate the ways and extent to which it might enhance their learning. The students generally expressed positive views about the resource, which they used in a variety of ways to supplement more traditional learning activities. They placed particular emphasis on the benefits of using the resource to reinforce lecture materials and to aid revision for exams. Less frequent, however, were references to deepened understanding of the subject matter, raising questions about the type of learning that students were engaged in. The possibility is discussed that ‘surface’ rather than ‘deep’ learning may be encouraged by this type of resource, and the potential tension is highlighted between the rhetoric of constructivism, which is prevalent in e‐learning, and the information transmission model of learning, which is highly influential and often favoured by students. 相似文献

This paper reports the findings of a science e‐journal initiative to publish undergraduate research and assesses student evaluations of this experience. Students in this (post‐1992, non‐research‐intensive) institution overwhelmingly reported that research was a key feature of their course at the point of the e‐journal introduction and that they were involved in research in a variety of ways (especially honours projects, lab work and fieldwork). Research‐informed teaching from the student perspective involved two specific categories of pedagogic activities: things that students did and things that tutors did. Students largely understood research‐informed teaching as an activity where tutors impart knowledge about their own and others' research (a research‐led approach). Yet, what students wanted was a more active involvement in the research process (research‐oriented/research‐based). The e‐journal initiative enabled some students to acquire this additional experience and without great cost so could be adopted elsewhere. There is some debate about equality of access to research opportunities in higher education, and an e‐journal has the potential to be more widely accessible than, for example, research apprenticeships (especially if students can be involved as reviewers and as active contributors via Web 2.0 technologies). However, there is still an element of elitism about selection for the publication process. 相似文献

The aims of this study were to examine and compare selected physiological and metabolic responses of wheelchair athletes in two paraplegic racing classes [T3: n?=?8 (lesion levels T1–T7; paraplegics); T4: n?=?9 (lesion levels below T7; paraplegics)] to prolonged exercise. In addition, we describe the responses of three tetraplegic athletes [T2: n?=?3 (lesion levels C6/C7: tetraplegics)]. Twenty athletes completed 90?min of exercise at 75% [Vdot]O2peak on a motorized treadmill adapted for wheelchairs. The mean (±s) heart rates of the T3 and T4 racing classes were 165±2 and 172±6 beats?·?min?1, respectively. For the T4 racing class, heart rate gradually increased during the test (P?<0.05), whereas for the T3 racing class, heart rate reached a plateau after an initial increase. The mean heart rate of the tetraplegics was 114±3 beats?·?min?1. The T3 and T4 classes exhibited similar respiratory exchange ratios, plasma lactate and glucose concentrations throughout the test. For both the T3 and T4 racing class, free fatty acid, glycerol, ammonia, urea and potassium concentrations had increased from resting values by the end of the test (P?<0.05). In conclusion, the results of this study suggest that endurance-trained wheelchair athletes are able to maintain velocities equivalent to the same relative exercise intensity (75% [Vdot]O2peak) for prolonged periods irrespective of lesion level. 相似文献

Reflecting on the think-aloud method for evaluating e-learning 总被引：1，自引：0，他引：1

E‐learning is increasingly being used in higher education settings, yet research examining how students use e‐resources is frequently limited. Some previous studies have used the think‐aloud method (an approach with origins in cognitive psychology) as an alternative to the more usual questionnaire or focus groups, but there is little discussion in the educational literature about the advantages and disadvantages of this approach. In this paper, we discuss our experience of using the think‐aloud method in a recent study, and we reflect on its potential contribution as a research method. A number of concerns about the method arose during our study, including the level of guidance given to participants, observer influence, and the complexity of data analysis. We conclude, however, that the richness of the data collected outweighs these constraints, and that the think‐aloud method has the potential to enhance research in this field. 相似文献
