This article aims to seek trainee educational psychologists’ (TEPs) views about their experiences of using Video Enhanced Reflective Practice (VERP) to support their professional development, with a particular focus on consultation and peer supervision skills for the VERP guider. Participants engaged in three cycles of VERP, reflecting upon their practice using video clips of themselves. An action research design was implemented and views from trainee EPs and the Video Interaction Guidance (VIG) supervisor were sought, using semi-structured interviews. Hybrid Thematic Analysis was used in order to analyse the data. Findings suggest that VERP was generally a positive experience for trainees and their experiences highlighted the impact of observing themselves in practice, as opposed to retrospective reflection. Trainee EPs selected factors to consider within a ‘shared review’ and reflected on their experiences of being filmed, the strengths and the challenges of which are considered.  相似文献

This investigation examined the effect of beetroot juice (BR) supplementation, a source of dietary nitrate (NO3?), on cycling time-trial (TT) performance and thermoregulation in the heat. In a double-blind, repeated-measures design, 12 male cyclists (age 26.6 ± 4.4 years, VO2peak 65.8 ± 5.5 mL.kg?1.min?1) completed four cycling TTs (14 kJ.kg?1) in hot (35°C, 48% relative humidity) and euthermic (21°C, 52%) conditions, following 3 days supplementation with BR (6.5 mmol NO3? for 2 days and 13 mmol NO3? on the final day), or NO3depleted placebo (PLA). Salivary NO3? and nitrite, core (Tc) and mean skin temperature (Tsk) were measured. Salivary NO3? and nitrite increased significantly post-BR supplementation (< 0.001). Average TT completion time (mm:ss) in hot conditions was 56:50 ± 05:08 with BR, compared with 58:30 ± 04:48 with PLA (= 0.178). In euthermic conditions, average completion time was 53:09 ± 04:35 with BR, compared with 54:01 ± 04:05 with PLA (= 0.380). The TT performance decreased (< 0.001), and Tc (< 0.001) and Tsk (< 0.001) were higher in hot compared with euthermic conditions. In summary, BR supplementation has no significant effect on cycling TT performance in the heat.  相似文献

This paper contributes a rich picture of how students from refugee backgrounds navigate their way into and through undergraduate studies in a regional Australian university, paying particular attention to their access to and use of different forms of support. We draw on the conceptualisation of ‘hot’ and ‘cold’ knowledge, offered by Ball and Vincent (1998. “‘I Heard it on the Grapevine’: ‘Hot’ Knowledge and School Choice.” British Journal of Sociology of Education 19 (3): 377–400), and the addition of ‘warm’ knowledge offered by Slack et al. (2014. “‘Hot’, ‘Cold’ and ‘Warm’ Information and Higher Education Decision Making.” British Journal of Sociology of Education 35 (2): 204–223), to develop an understanding of how students from refugee backgrounds make choices about how they locate, select and access support for their studies. The findings of this paper suggest that students from refugee backgrounds do not view the ‘cold’ (unfamiliar-formal) institutional support on offer as ‘for them’; instead they expressed a preference for the ‘warm’ (familiar-formal) support offered via ‘trusted’ people who act as literacy/sociocultural brokers or ‘hot’ (familiar-informal) support of their grapevine of other students (past and present) or experienced community members.  相似文献

The aim of this study was to compare sprint performance over 10 and 20?m when participants ran while towing resistances, weighing between 0 and 30% of body mass. The sample of 33 participants consisted of male rugby and soccer players (age 21.1?±?1.8 years, body mass 83.6?±?13.1?kg, height 1.82?±?0.1?m; mean?±?s). Each participant performed two sets of seven sprints over 20?m using a Latin rectangular design. The times were recorded at 10 and 20?m using electronic speed gates. The sprints of 13 players were video-recorded to allow calculation of stride length and frequency. For both sprints, a quadratic relationship was observed between sprint time and resistance as sprint time increased from 2.94?s to 3.80?s from 0 to 30% resistance. This relationship was statistically significant but considered not to be meaningful for performance because, over the range of resistances used in this study, the quadratic model was never more than 1% (in terms of sprint time) from the linear model. As resistance increased, the stride length shortened, with mean values of 1.63?±?0.13?m at 0% body mass and 1.33?±?0.13?m at 30% of body mass. There was no significant change in stride frequency with increasing resistance. The results show that in general there is an increase in sprint time with an increase in resistance. No particular resistance in the range tested (0?–?30%) can be recommended for practice.  相似文献

Abstract

This study determined how experts see the future of adult fitness by using the Delphi Technique as a measurement tool. Experts (n = 50), all Fellows of the American College of Sports Medicine, were selected on the basis of their reputations in adult fitness. Three questionnaires were submitted to the panel. In the first questionnaire each expert listed five or more events, trends, or developments they thought would take place and five or more events they would like to see take place in the next 25 years. From the events and trends listed on this questionnaire, 100 items were generated that formed the basis for the last two questionnaires. Responses to the items on the second questionnaire were evaluated on a 5-point Likert scale for probability and desirability. In the third questionnaire, group means and standard deviations were calculated and recorded for each item. Only those items which were significantly (p < .01) higher than 3.0, the average probability or desirability response on the Likert scale, were included in the analysis. The items were divided into seven categories: fitness in sport and recreation, fitness and wellness, fitness in industry, fitness in education, fitness in business, research in fitness, and fitness equipment and facilities. The highest single mean for any item for both probability (M = 4.31) and desirability (M = 4.83) was increased awareness of health and fitness among the elderly.  相似文献

Abstract

A statewide program assessment was established to make positive change in physical education school programs in South Carolina. Reform efforts depend both on balancing accountability for change and teacher support for change (Odden &Anderson, 1986). The purpose of the study was to determine teacher perceptions of the South Carolina Physical Education Assessment Program and its effects across six related themes including: changes in teaching and learning, changes in curriculum and instruction, teacher awareness of the assessment program, teacher support for the program, work place conditions, and the advocacy role of the program. It was also the purpose of this study to determine if the survey responses were in any way related to teacher and school variables. The overall results of the study indicated positive change and support for the assessment program, supporting the viability of the standards, assessment, and accountability reform effort to positively impact physical education programs.  相似文献

Intertwining case study with practitioner inquiry, a research team seeks language for the conduct of mindful curricular enactment in an alternative public middle school. The school is committed to valuing students’ narratives of experience, the resources all bring to the school, and the given particularities of contexts, subject matter, and situations, as the makings comprising learning within and through community. A collaborative approach to inquiry that involves all team partners in the research process and engages the unique strengths that each brings focuses on how this alternative school provides a case for accessing how and why mindful curricular enactment orients accordingly. It is the makings forming this curricular movement, and the room found within these makings to reorganize and reconstruct thinking, that primary attention is oriented towards. Deweyan ‘roominess’ negotiated through such curricular enactment is documented as mindful attention to curriculum-making that fosters the needed room—the conditions and supports sustaining an individual/collective movement of thinking. Such movement is revealed as necessarily receptive, inciting community (re)making. Its inspirited nature is revealed through participatory modes of being and associated habits embracing knowledge-making as generative, elemental to being human, in need of other(s), assuming temporal/spatial agency, and interdependent with imagination, instilling embodied understandings.  相似文献
