Background: In many countries around the world, physical education (PE) has been identified as a marginalized subject. PE teachers have been found to feel negative consequences associated with marginality, such as stress, burnout, and early career attrition. Recent evidence also indicates that physical educators can develop a sense of perceived mattering both in relation the subject of PE and their role as that teacher of that subject. Less is known, however, about the relationship between perceived mattering and marginalization, and how teachers navigate social messages associated with each that they receive while teaching. Role socialization theory has emerged as an approach to studying teachers’ experiences in school environments, and can be used to understand their experiences with marginality and mattering.

Aims: The purpose of this study was to understand how the social environment of schools influences PE teachers’ perceptions of marginalization and perceived mattering, and how these two constructs interact.

Method: The investigation was conceptualized as an interview study, and framed using a social constructivist epistemology. Participants included 30 in-service PE teachers (16 males, 14 females) from the Midwest region of the US. Data were collected using in-depth qualitative interviews, and analyzed through a collaborative approach to data analysis that drew upon both inductive and deductive forms of analysis.

Results: Participants identified experiences with both perceived mattering and marginalization in their work, and noted that sometimes these messages were contradictory. Some participants felt the effects of marginalization as their discipline was viewed as a dispensable commodity that is only meaningful for the service it provides to other teachers (e.g. gives elementary classroom teachers a break for planning). Some of the teachers internalized their marginal status and began to see their primary function as supporting the work of teachers in other subjects. Nevertheless, the participants derived a sense of mattering by building relationships with colleagues, administrators, and students, and by advocating for the discipline. Teachers also felt validated when colleagues acknowledge their attempts to implement effective practices, but struggled when working with colleagues who are resistant to change.

Conclusions: PE teachers experience both marginalization and perceived mattering, which are shaped largely by social interactions within the school environment. This study specifically lends to the view of marginalization and perceived mattering as two constructs at opposite ends of a continuum, rather than a binary conceptualization. This suggests that it could be the summation of marginalizing experiences and those that promote mattering that lead physical educators to develop overall impressions of their role in schools. Furthermore, this study adds to the literature indicating that physical educators may eventually internalize feelings of marginalization when consistently told that they do not matter. This has implications related to the washout effect whereby teachers who no longer feel as if they are making meaningful contributions to children’s education may compromise their teaching practice.  相似文献

The purpose of the present study was to examine the acute effects of resting, aerobic exercise practised alone, and aerobic exercise with active video games (AVG), on complex reaction time (CRT) and the post-exercise acute rate of perceived exertion (RPE) in young healthy adults. The experimental group was composed of 92 healthy young adults, 78 males and 13 females (age M?=?21.9?±?2.7 years) who completed two sessions, A and B. In session A, participants rode 30?min on an ergometer, while in session B they exercised for 30?min on an ergometer while playing an AVG on a Wii. The control group was composed of 30 young adults, 26 males and 4 females (age M?=?21.4?±?2.9 years) who rested for 30?min. In each session, a CRT task was performed before and after exercising or resting, and post-exercise global RPE was noted. Repeated measures general linear model (GLM) and Wilcoxon tests were performed. (1) Both aerobic exercise alone and aerobic exercise combined with AVG improved CRT, while resting did not; (2) aerobic exercise combined with AVG did not improve CRT more than aerobic exercise only; and (3) RPE was lower after aerobic exercise combined with AVG compared with aerobic exercise only. In young adults, exercise produces acute benefits on CRT, and practising exercise with AVG helps to decrease RPE.  相似文献

This study examined the relation between losing a game and players’ destructive voice about the coach. As team performances would suffer when such behaviours are not managed properly, we tested the motivational climate as a potential mechanism by which coaches can manage these destructive behaviours. Twelve volleyball and basketball teams (= 136) were weekly assessed during eight weeks using questionnaires. Players rated the extent to which their teammates expressed destructive voice about their coach. Each player’s indegree centrality (i.e. the average score received from all teammates) functioned as measurement of his/her destructive voice about the coach. As hypothesized, losing a game increased players’ expression of destructive voice about the coach. At both the within- and between-person level, perceived mastery (performance) climate negatively (positively) predicted players’ destructive voice about the coach. When players perceived a more salient performance climate than usual after a loss, their increase in destructive voice about the coach was magnified. These results highlight the dynamics of players’ destructive voice about the coach and how a single loss can start the utterance of such voice. A coach would be able to counter this process by increasing the focus on a mastery rather than a performance climate.  相似文献

Introduction: Secondary schools have the potential to promote health-related fitness (HRF) and physical activity within and outside school hours. As such, schools are often chosen as the setting to implement child and adolescent physical activity programs. School-based programs often utilise teachers as delivery agents, but few studies examine effects on teacher-level outcomes.

Purpose: The primary aim of this study was to determine the impact of teacher training embedded within a physical activity intervention on teacher-level outcomes. The secondary aim of this study was to evaluate process data, including implementation, satisfaction and fidelity.

Methods: Resistance Training for Teens (RT for Teens) was evaluated using a cluster randomised controlled trial in 16 secondary schools. Teachers (N?=?44; 48% female/52% male; mean?±?SD years teaching experience?=?10.6?±?8.0) from 16 secondary schools were assessed at baseline. Intervention group teachers (i.e. from eight schools) delivered a structured school-based physical activity program over 10-weeks. Teacher outcomes included confidence to teach health-related fitness (HRF) activities, perceived barriers to teaching HRF activities, and perceived fitness. Detailed process evaluation data were also collected. Assessments were conducted at baseline and 6-months (post-program), and outcomes were assessed using repeated measures analysis of variance.

Results: There was a positive group-by-time effect for the confidence composite score (p?=?.010, partial eta squared?=?0.29), but no effects for the two (contextual, interpersonal) barrier composite scores. Also, there was a significant effect for perceived ‘general fitness’ (p?=?0.044, partial eta squared?=?0.13), but not for specific fitness subdomains. Teachers were highly satisfied with both the training and the program, believing it was beneficial for students. Resource usage and adherence to the SAAFE (Supportive, Active, Autonomous, Fair, Enjoyable) delivery principles was high.

Conclusion: RT for Teens improved teachers’ confidence and perceived fitness. These findings highlight the potential for high-quality teacher training and program delivery to positively influence teacher-level outcomes. This may provide support for the use of teacher professional development to improve HRF-related pedagogy.  相似文献

During the late twentieth century, the United Kingdom’s football infrastructure and spectatorship underwent transformation as successive stadia disasters heightened political and public scrutiny of the game and prompted industry change. Central to this process was the government’s formation of an independent charitable organization to oversee subsequent policy implementation and grant-aid provision to clubs for safety, crowd, and spectator requirements. This entity, which began in 1975 focusing on ground improvement, developed into the Football Trust. The Trust was funded directly by the football pools companies who ran popular low-stakes football betting enterprises. Working in association with the Pools Promoters Association (PPA), and demonstrating their social responsibility towards the game’s constituents, the pools resourced a wide array of Trust activities. Yet irrespective of government mandate, the PPA and Trust were continually confronted by political and economic obstacles that threatened the effectiveness of their arrangements. In this paper the history of the Football Trust is investigated, along with its partnership with the PPA, and its relationship with the government within the context of broader political shifts, stadia catastrophes, official inquiries, and commercial threats. It is contended that while the Trust/PPA partnership had a respectable legacy, their history afforded little protection against adverse contemporary conditions.  相似文献

If there is one phenomenon which highlights the lack of role distance of certain sport actors, it is obviously hooliganism. In the mid-1980s, Norbert Elias and Eric Dunning became interested in the role played by modern sports in the ‘civilising process’ and, analysing the violence of sport crowds, introduced a culturalist interpretation of the actions. They were considered to be the work of members of the ‘rough working class’, who were less advanced in the ‘civilising process’ and had still not achieved sufficient self-control. In these groups, characterised by social functioning in the form of a segmentary bond, violence was thought to be a traditional way of resolving conflicts, a significant aspect and essential part of their ethos. This is an over-determined interpretation of the violence of sports crowds which naturalises and socialises this violence. This vision poses a problem, that of the negation of any logic on the part of the actors involved. This viewpoint leads us to consider violence as a social product and a ‘practical accomplishment’, the result of the way in which supporters interpret and live in the world that surrounds them, and, as such, it is the individual and collective motives and purposes that should be investigated.  相似文献

Perceived and actual motor competence (MC) influence physical activity (PA) behaviour. Notably, both are lower in girls than in boys. This study aimed to investigate (i) whether a 12-week, teacher-led intervention that improves actual MC (Lander, N., Morgan, P. J., Salmon, J., & Barnett, L. M. (2017). Improving early-adolescent girls’ motor skill: A cluster randomized controlled trial. Medicine and Science in Sports and Exercise. 49(12), 2498–2505) could also improve adolescent girls’ physical self-perception and perceived MC, and (ii) whether change in actual MC is associated with post-intervention perceptions A randomized controlled trial with 171 girls (mean age 12.48 ± 0.34 years), measured perception (i.e., physical self-perception profile (PSPP) and pictorial scale of perceived movement skill competence (PMSC)) and actual MC (i.e., Victorian FMS Teachers’ Assessment Manual). Mixed models with post-intervention perception as the outcome, adjusting for baseline perception, group, and change in actual MC, as well as clustering, were performed. An interaction term between change in MC and intervention status was included to test the secondary aim. There were significant intervention effects on girls’ physical self-perception as well as their perceived MC. However, there was no association between change in actual MC across the intervention and post intervention perception. While the intervention improved both actual MC and perceived MC, they were not associated.  相似文献

This prospective study was designed to investigate the influence of high students' perceived teacher autonomy support in mandatory physical education on their intention and actual enrollment in elective physical education. Participants included 545 ninth-grade students enrolled in three suburban high schools in a major midwestern metropolitan area. A series of hypothesized models related to autonomy support within the Theory of Planned Behavior were tested. Structural equation modeling results demonstrated that perceived autonomy support provided by teachers in mandatory physical education could predict elective physical education enrollment indirectly via the mediation of attitudes and intention in the Theory of Planned Behavior Providing support for students' autonomy in physical education may hold potential promise for enhancing their future physical activity engagement.  相似文献

Eighteen volunteer female subjects received preliminary instruction in a simple gymnastics bench sequence. They were then given a pre‐intervention test on a bench at ground level. Self‐reported distress, an independent observer's ratings of distress and heart rates were monitored immediately prior to performance of the sequence. Performances were also videotaped and formally scored by a qualified gymnastics judge. Subjects were then randomly assigned to a stress inoculation training group or a ‘no stress management’ training control group. Stress inoculation group subjects then received seven sessions of training in relaxation, imagery and making self‐statements in order to develop a set of coping skills. Control group subjects also received seven training sessions during which they practised a series of coordination exercises, but no psychological stress management training was given to this group.

All subjects were then re‐tested on the bench sequence but this time at a height of 1.52 m. Self‐reported stress, observer's ratings of distress and heart rate were recorded as before. Performance was again videotaped for scoring. The stress inoculation group reported significantly less stress prior to the test on the elevated beam than the control group. However, the groups did not differ in terms of heart rate. Further, the stress inoculation group performed reliably better than the control group on the elevated bench.  相似文献

Academic responses to Wikipedia since its inception in 2001 have shifted from scepticism and hostility to serious critique. Wikipedia is a project driven by a community of amateur, and sometimes professional, scholars and it is this community – and associated rules and practices – that shapes the site's publicly viewable content. Despite the centrality of egalitarianism and communal wisdom to the Wikipedian ethos, the encyclopaedia is not filled equitably with historical knowledge or topics. This article addresses the role of Wikipedia in the production of knowledge in a sport history context. An analysis of 115 Wikipedia articles written about notable Australian sportspeople revealed a disproportionately large group of high-quality cricket biographies. Further investigation revealed that a small group of Wikipedians were responsible for writing these articles. The work of this community of practice is indicative of the influence that dedicated special interest groups can have over the production of knowledge on Wikipedia and raises broader questions about the production of knowledge in sport history.  相似文献

Abstract

The aims of this study were to examine the acute effects of static stretching on peak torque, work, the joint angle at peak torque, acceleration time, isokinetic range of motion, mechanomyographic amplitude, and electromyographic amplitude of the rectus femoris during maximal concentric isokinetic leg extensions at 1.04 and 5.23 rad · s?1 in men and women. Ten women (mean ± s: age 23.0 ± 2.9 years, stature 1.61 ± 0.12 m, mass 63.3 ± 9.9 kg) and eight men (age 21.4 ± 3.0 years, stature 1.83 ± 0.11 m, mass 83.1 ± 15.2 kg) performed maximal voluntary concentric isokinetic leg extensions at 1.04 and 5.23 rad · s?1. Following the initial isokinetic tests, the dominant leg extensors were stretched using four static stretching exercises. After the stretching, the isokinetic tests were repeated. Peak torque, acceleration time, and electromyographic amplitude decreased (P≤ 0.05) from pre- to post-stretching at 1.04 and 5.23 rad · s?1; there were no changes (P > 0.05) in work, joint angle at peak torque, isokinetic range of motion, or mechanomyographic amplitude. These findings indicate no stretching-related changes in the area under the angle – torque curve (work), but a significant decrease in peak torque, which suggests that static stretching may cause a “flattening” of the angle – torque curve that reduces peak strength but allows for greater force production at other joint angles. These findings, in conjunction with the increased limb acceleration rates (decreased acceleration time) observed in the present study, provide tentative support for the hypothesis that static stretching alters the angle – torque relationship and/or sarcomere shortening velocity.  相似文献
