Changing lives? Critical evaluation of a school-based athlete role model intervention     

Kathleen Armour 《Sport, Education and Society》2013,18(3):381-403

There would appear to be an enduring belief that successful sportsmen and women can act as powerful motivational role models for young people, especially disaffected, disadvantaged or disengaged youth. In the UK, for example, this belief has been expressed recently in the development of programmes, such as changingLIVES, the Respect Athlete Mentor Programme and Playing For Success. There are further examples around the world of programmes based on similar beliefs including Sporting Partnerships, Athlete Development Australia, Active Girls Breakfast and the Whitelion Sports and Recreation program. This paper reports an evaluation of the changingLIVES ‘athlete mentor’ programme in the UK. This was a school-based programme using successful sports people to deliver a series of motivational activities to young people who were identified as being disengaged or disaffected in some way. Conceptual confusion in the terms ‘mentor’ and ‘role model’ evident in the literature was mirrored in the programme design. The design of an appropriate evaluation strategy was constrained by the scale of the programme aims and the comparatively low evaluation budget. Nonetheless, detailed data were collected on individual pupils. Evaluation data suggested that although the teachers and young people did report an immediate positive reaction to the activities, there was limited evidence of a wider impact on young people's behaviour, school attendance or self-esteem. It is argued that there should be greater conceptual clarity and a stronger evidence base supporting the design and delivery of interventions in schools that seek to use sports people as role models (or mentors) for young people.  相似文献   

Do as we do and not as we say: teacher educators supporting student teachers to learn on teaching practice     

Fiona C. Chambers  Kathleen M. Armour 《Sport, Education and Society》2013,18(4):527-544

This paper reports data from a larger study into the ways in which Physical Education Teacher Education (PETE) students engaged in professional learning during teaching practice (TP) in Ireland. The study comprised one umbrella case study of Greendale University, schools and PETE students that consisted of five individual cases: tetrads of PETE student teacher, cooperating teacher (CT), University tutor (UT) and School Principal (SP). Each tetrad was defined as a unique community of practice located within the wider structures of school, education and university policies on teacher education. Data were collected over one academic year using qualitative research methods and grounded theory as a systematic data analysis tool.

Findings indicate that in each of the five cases, support for PETE student learning was, to some degree, dysfunctional. In particular, it became evident that there were two conflicting teacher-learning curricula in operation. The official curriculum, expressed in policy and by SPs, UTs and CTs (also referred to as mentors), valued a PETE student who cared for pupils, had a rich pedagogical content knowledge, knew how to plan for and assess pupils’ learning, valued reflection, and was an active member of a community of practice. The unofficial but essentially more powerful enacted curriculum, encouraged PETE students to draw upon their own resources to learn pedagogical content knowledge in an isolated and unsupported manner.

The data highlight the force of the unofficial curriculum and the ways in which PETE students were guided to the core of the dysfunctional community of practice by untrained CTs (mentors) and untrained UTs. PETE students in this study learned to survive in a largely unsupportive professional learning environment and, just as theories of social reproduction intimate, indicated that they would reproduce this practice with PETE students in their care in the future.

The findings suggest that in cases similar to those studied, there is a need for teacher educators in Ireland, (in both universities and schools) to critically interrogate their personal practices and implicit theories of teacher education and to engage in training for their role. There is also evidence to suggest that PETE students in Ireland could benefit from the development of school–university partnerships that act as fundamental units of high quality professional learning. In the cases studied, this may have led to a stronger focus on the intended or official curriculum of TP, led by the revised maxim: ‘Do as we say and as we do’.  相似文献   

The effect of coaching intervention on elite fast bowling technique over a two year period

Fast bowling in cricket is an activity that is well recognised as having high injury prevalence and there has been debate regarding the most effective fast bowling technique. The aim of this study was to determine whether two-year coaching interventions conducted in a group of elite young fast bowlers resulted in fast bowling technique alteration. Selected kinematics of the bowling action of 14 elite young fast bowlers were measured using an 18 camera Vicon Motion Analysis system before and after two-year coaching interventions that addressed specific elements of fast bowling technique. Mann-Whitney tests were used to determine whether any changes in kinematic variables occurred pre- and post-intervention between those who had the coaching interventions and those who didn't. The coaching interventions, when applied, resulted in a more side-on shoulder alignment at back foot contact (BFC) (p = 0.002) and decreased shoulder counter-rotation (p = 0.001) however, there was no difference in the degree of change in back and front knee flexion angles or lower trunk side-flexion. This study has clearly shown that specific aspects of fast bowling technique are changeable over a two-year period in elite level fast bowlers and this may be attributed to coaching intervention.  相似文献   

Effects of a verbal and visual feedback system on running technique,perceived exertion and running economy in female novice runners     

Stephen P. Messier  Kathleen J. Cirillo 《Journal of sports sciences》2013,31(2):113-126

The purpose of this study was to determine the effects of a verbal and visual feedback system on running technique, ratings of perceived exertion (RPE), and running economy. Twenty‐two female novice runners were randomly assigned to experimental (n = 11) and control (n = 11) groups. The experimental subjects received verbal and visual feedback concerning their running technique prior to and during each training run. Training involved 15 20‐min treadmill running sessions over a 5‐week period. The control group adhered to the same training routine but did not receive feedback concerning their running technique. High‐speed (100 Hz) photography was used to collect biomechanical data. A submaximal oxygen consumption test and Borg's RPE scale were used to collect data concerning running economy and perceived exertion, respectively. Statistical analysis using ANCOVA revealed that the proposed feedback system had a significant (P < 0.01) effect on the experimental group's running technique by affecting the following desired changes relative to the control group: greater relative stride lengths, shorter support time, greater ankle dorsiflexion during support and greater knee flexion during support and non‐support. There were no significant differences between the groups in submaximal VO₂ or RPE. The results of this study suggest that verbal and visual feedback are effective means of eliciting modifications in running style in female novice runners. The link between modifications in running style and improvements in running economy and perceived exertion remains unclear.  相似文献   

The relationship between bowling action classification and three-dimensional lower trunk motion in fast bowlers in cricket     

Craig A. Ranson  Angus F. Burnett  Mark King  Nitin Patel  Peter B. O'Sullivan 《Journal of sports sciences》2013,31(3):267-276

Abstract

Lower back injuries, specifically lumbar stress fractures, account for the most lost playing time in professional cricket. The aims of this study were to quantify the proportion of lower trunk motion used during the delivery stride of fast bowling and to examine the relationship between the current fast bowling action classification system and potentially injurious kinematics of the lower trunk. Three-dimensional kinematic data were collected from 50 male professional fast bowlers during a standing active range of motion trial and three fast bowling trials. A high percentage of the fast bowlers used a mixed bowling action attributable to having shoulder counter-rotation greater than 30°. The greatest proportion of lower trunk extension (26%), contralateral side-flexion (129%), and ipsilateral rotation (79%) was used during the front foot contact phase of the fast bowling delivery stride. There was no significant difference in the proportions of available lower trunk extension, contralateral side-flexion, and ipsilateral rotation range of motion used during fast bowling by mixed and non-mixed action bowlers. Motion of the lower trunk, particularly side-flexion, during front foot contact, in addition to variables previously known to be related to back injury (e.g. shoulder counter-rotation), should be examined in future cross-sectional and prospective studies examining the fast bowling action and low back injury.  相似文献

Contextual Factors and Age Group Differences in Coincidence-Anticipation Performance     

Kathleen M. Haywood  Gail Greenwald  Catherine Lewis 《Research quarterly for exercise and sport》2013,84(4):458-464

Abstract

Age group differences in the direction of anticipatory motor responses may be attributable to the increased susceptibility of young children to contextual factors. That is, their performances on a given trial may be influenced by the stimulus speed presented in the previous trial. Mixed-sex groups of 8–9 year-olds and adults were given 3 blocks of 18 coincidence-anticipation trials each in a counterbalanced design. One block contained stimulus speeds of 1, 3, or 5 MPH, another speeds of 3, 5, or 7 MPH, and a third speeds of 5, 7, or 9 MPH, so that the 5 MPH speed was common to all blocks. An age group by sex by testing order by trial block ANOVA of constant error on the 5 MPH trials indicated that trial block was a significant factor within an age group by block interaction. Mean scores showed that the children responded very early in the 5–7–9 MPH block to the 5 MPH stimuli while the adults did not. Testing order was also a significant factor: subjects in the 1–3–5, 5–7–9, 3–5–7 MPH order performed with significantly greater directional error. While the later finding may indicate contextual factors influenced performance, there is no strong evidence that contextual factors differentially affected the age groups.  相似文献   

Interparental conflict in kindergarten and adolescent adjustment: prospective investigation of emotional security as an explanatory mechanism     

Cummings EM  George MR  McCoy KP  Davies PT 《Child development》2012,83(5):1703-1715

Advancing the long‐term prospective study of explanations for the effects of marital conflict on children’s functioning, relations were examined between interparental conflict in kindergarten, children’s emotional insecurity in the early school years, and subsequent adolescent internalizing and externalizing problems. Based on a community sample of 235 mothers, fathers, and children (Ms = 6.00, 8.02, 12.62 years), and multimethod and multireporter assessments, structural equation model tests provided support for emotional insecurity in early childhood as an intervening process related to adolescent internalizing and externalizing problems, even with stringent autoregressive controls over prior levels of functioning for both mediating and outcome variables. Discussion considers implications for understanding pathways between interparental conflict, emotional insecurity, and adjustment in childhood and adolescence.  相似文献   

Immigrant–Native Differences in Child Health: Does Maternal Education Narrow or Widen the Gap?     

MI Jackson  K Kiernan  S McLanahan 《Child development》2012,83(5):1501-1509

Abundant U.S. research documents an “immigrant advantage” in children’s physical health. This article extends consideration to the United Kingdom, permitting examination of a broader group of immigrants from disparate regions of the world and different socioeconomic backgrounds. Drawing on birth cohort data (ages 0–5) from both countries (n = 4,139 and n = 13,381), the analysis considers whether the children of immigrants have a physical and mental health advantage around the beginning of elementary school, and whether advantage is more pronounced among low‐educated populations. Findings indicate that the children of immigrants are not uniformly healthier than those in native‐born families. Rather, there is heterogeneity in the immigrant advantage across outcomes, and evidence of both greater advantage and disadvantage among children in low‐educated immigrant families.  相似文献   

A Case Study of a Turnaround High School: An Examination of the Maryland State Department of Education Breakthrough Center Intervention     

Claudia Galindo  Kathleen Stein  Eugene Schaffer 《Journal of Education for Students Placed at Risk》2016,21(4):208-229

This study examined the Maryland State Department of Education Breakthrough Center (BTC) engagement in a Baltimore City turnaround high school. Utilizing a case-study design and mixed-methods research, data were collected through interviews, informal observations, and review of administrative and achievement documents. Beginning in the 2011–2012 academic year, the BTC has been working in collaboration with school personnel to improve the educational experiences and academic achievement of students. School personnel recognized that the BTC has been responsive to teachers' requests and has exhibited a flexible approach building collaborative and nonevaluative relations. Administrative and achievement data also indicated improvement in school outcome measures during the past 3 years. Nevertheless, school faculty also identified important challenges of the BTC intervention, such as the relevance of this intervention for veteran teachers, the extent to which the needs of all student populations were met, and the sustainability of the intervention.  相似文献
