Assessing intellectual potential in Tanzanian children in poor areas of Dar es Salaam     

Steve Humble  Ian Schagen 《Assessment in Education: Principles, Policy & Practice》2018,25(4):399-414

The research set out in this paper attempts to identify whether one of three conventional IQ tests is more capable of identifying intellectual potential amongst poor children in Dar es Salaam. To this end 1857 children from 17 government schools in poor districts of Dar es Salaam were asked to complete a questionnaire and undertake a range of tests. The study included teacher, peer and self-nomination. It has been noted that static testing may not fully elicit the abilities of African children. It has been suggested that dynamic testing might provide a more fair and equitable means of assessment. Therefore 101 students took part in a control and intervention group in order to investigate. The findings show a significant correlation between IQ test scores and other test outcomes. Those with larger families and older children perform less well on IQ tests. Peer ability and self-confidence positively influence test scores.  相似文献   

Teachers communicating about life-limiting conditions,death and bereavement     

Sally Robinson  Alison Ekins  Ian Durrant  Kathryn Summers 《Pastoral Care in Education》2018,36(1):57-69

The number of children with life-limiting or life-threatening conditions in England is double what it was at the millennium. These conditions include cystic fibrosis, cancer, organ failure and severe neurological injuries. The Teaching for Life project aimed to explore the needs of teachers working in English schools in relation to working with children with life-limiting or life-threatening conditions. Ninety teachers completed a questionnaire and 38 completed individual and group interviews. About half the teachers interviewed had experience of working with children with life-limiting or life-threatening conditions, and half did not. The teachers expressed a number of anxieties about coping with illness, death and bereavement. They described difficulties in communicating with parents, children and health professionals. They worried about maintaining their professional role whilst needing to contain their own emotions and the emotions of others, within school cultures that did not feel supportive. The paper concludes that policies and practices that seek to support children with medical conditions need to acknowledge the weight of responsibility for teachers. They need to articulate with a whole school approach that protects and promotes teachers’ emotional well-being.  相似文献   

Leadership in governance: Exploring collective board leadership in sport governance systems     

Lesley Ferkins  David Shilbury  Ian O’Boyle 《Sport Management Review》2018,21(3):221-231

The purpose of this paper is to introduce and explore a working conceptualisation of collective board leadership in a federal sport network. In this paper, the authors examine the relationship between collective leadership and governance systems specifically within the non-profit sport organisation context, bringing together notions of collective board leadership and collaborative governance. Neither concept has yet been presented in tandem for the benefit of developing sport governance knowledge and practice. As an outcome of the conceptualising, the authors make explicit the multiple levels of the sport governance system and pose two broad research directions that will help advance theory and drive a better understanding of collective board leadership within these types of governance systems. A central premise of this paper is that the sport management field is lacking literature that brings together leadership and governance, and that collective leadership is a topic where the intersection of leadership and governance renders advancement for both bodies of work. The authors offer implications for future work in collective leadership for sport governance.  相似文献   

Change-of direction deficit in elite young soccer players

Change-of-direction (COD) ability is an essential physical component for soccer. This study examined the relationships between conventional speed–power assessments and COD performance in elite young soccer players. Twenty-five under-20 male players from the same club (age: 17.6?±?0.8 years, height: 178.1?±?6.7?cm, body mass [BM]: 72.2?±?7.9?kg) performed sprint speed tests, vertical jumps, loaded jump squats, half squats, and Zigzag COD assessments. Moreover, the COD deficit was calculated as the difference between 20-m sprint velocity and Zigzag COD test velocity. A Pearson correlation analysis was used to determine the correlations between Zigzag COD performance and COD deficit with speed and power outputs. Although no significant relationships between speed–power variables and COD ability were present, there were still strong positive correlations between traditional neuromechanical measures and COD deficit. Briefly, it seems that higher performances in speed and power tests are not necessarily related to better performances in specific COD maneuvers. Therefore, it is recommended that coaches and technical staff include specific COD drills in soccer player routines to optimize the transference from speed and power capacities to specific COD performance.  相似文献   

Coaching efficacy research: learning from the past and looking to the future     

Ian D. Boardley 《International review of sport and exercise psychology》2018,11(1):214-237

Coaching efficacy (CE) represents the extent to which coaches believe they have the capacity to affect the learning and performance of their athletes, and the CE model details antecedents, dimensions and outcomes of CE. Based around the CE model, the present paper had two main aims. First, to present a comprehensive and critical review of the research underpinned by the CE model. Studies were categorised by whether they investigated antecedents, outcomes or athletes’ perceptions of their coach. Twenty-one published studies were identified for the review. Overall the review provides support for the main tenets of the CE model, with researchers establishing links between CE and many of the antecedents and outcomes proposed in the model. The second aim was to assimilate findings from the review, limitations in the CE model and relevant conceptual models to present a revised CE model. Whilst retaining the essence of the original model, the revised model also incorporates explicit processes linking coach beliefs and athlete perceptions, antecedents of athlete perceptions and an intrarelationship source of CE. It also incorporates specific categories of coach behaviour and athlete-/team-level outcomes. The paper concludes by identifying limitations in the literature and review, and by proposing key directions for future research.  相似文献   

The association between fundamental athletic movements and physical fitness in elite junior Australian footballers     

Carl T. Woods  Ian McKeown  Justin Keogh  Sam Robertson 《Journal of sports sciences》2018,36(4):445-450

This study investigated the associations between fundamental athletic movement and physical fitness in junior Australian football (AF). Forty-four under 18 players performed a fundamental athletic movement assessment consisting of an overhead squat, double lunge, single leg Romanian deadlift and a push up. Movements were scored on three assessment criterions using a three-point scale. Additionally, participants performed five physical fitness tests commonly used for talent identification in AF. A Spearman’s nonparametric correlation matrix was built, with correlation coefficients being visualised using a circularly rendered correlogram. Score on the overhead squat was moderately positively associated with dynamic vertical jump height on left (r_s = 0.40; P ≤ 0.05) and right (r_s = 0.30; P ≤ 0.05) leg take-off, stationary vertical jump (r_s = 0.32; P ≤ 0.05) and negatively associated with 20-m sprint time (r_s = ?0.35; P ≤ 0.05). Score on the double lunge (left/right side) was moderately positively associated with the same physical fitness tests as well as score on the multistage fitness test. Results suggest that improvements in physical fitness qualities may occur through concurrent increases in fundamental athletic movement skill, namely the overhead squat and double lunge movements. These findings may assist with the identification and development of talent.  相似文献   

A systematic approach to analysing sports performance     

Ian M. Franks  David Goodman 《Journal of sports sciences》2013,31(1):49-59

A systematic approach to the analysis of sporting events is discussed. The basic tenet is that objective quantification of critical events is required for a complete analysis. This approach encompasses diverse areas of methodology and research, such as quantification, biomechanics and physiology. The theoretical underpinnings are behavioural, in so far as athletes produce observable behaviour that can be quantified and ultimately changed. Several areas of analysis are linked together in a general framework and each one of these areas is dealt with in detail.  相似文献

Effects of bicycle frame ergonomics on triathlon 10-km running performance     

Ian Garside  Dominic A. Doran 《Journal of sports sciences》2013,31(10):825-833

It is perceived that, during the triathlon or duathlon, cycling with a steep (>76°) rather than a shallow (?76°) frame geometry might attenuate the fatigue associated with progression from the cycle to run disciplines and improve subsequent 10-km running performance. This is based on anecdotal testimony from athletes purporting to have experienced improved performance; no empirical evidence exists. To evaluate this view, eight male triathletes completed a counterbalanced, 40-km cycle ride at two frame geometries (73° and 81°) at ~70% VO 2peak . Immediately after completion of each 40-km cycle, a self-paced 10-km treadmill time trial was undertaken, during which physiological, kinematic and performance variables were measured. The 10-km run performance (mean - s : 42:55 - 4:19 vs 46:15 - 4:52 min; P ? 0.01) and combined cycle and run performance (1:45:49 - 5:45 vs 1:50:33 - 6:08; P ? 0.001) were faster in the 81° than the 73° condition. Improvements in performance were most prominent during the first 5 km of the run (21:41 - 2:15 vs 24:15 - 2:31 min in the 81° and 73° conditions respectively). These improvements were not evident during the second 5 km of the run. No differences in physiological variables were noted, although heart rate, stride length and stride frequency were increased during the 81° condition ( P ? 0.05). Modifying frame geometry from a seat tube angle of 73° to 81° improves 10-km running and combined cycle plus run performance. These improvements in performance might relate to alterations during the cycling phase, which minimizes the 'residual effect' of this (i.e. the adverse changes in substrate availability, thermoregulatory, cardiovascular and biomechanical factors felt immediately after transition from cycling to running) and attenuates negative changes in physiological and kinematic responses during the 10-km run.  相似文献   

An examination of psychosocial variables moderating the relationship between life stress and injury time-loss among athletes of a high standard     

Ian W. Ford  Robert C. Eklund  Sandy Gordon 《Journal of sports sciences》2013,31(5):301-312

Based on Williams and Andersen's model of stress and athletic injury, six psychosocial variables were assessed as possible moderators of the relationship between life stress and injury among 121 athletes (65 males, 56 females) competing in a variety of sports at state, national or international level. No significant effects of the sex of the participants were evident. Correlational analyses revealed moderator effects of several variables. Specifically, dispositional optimism and hardiness were related to decreased injury time-loss in athletes when positive life change increased, and global self-esteem was associated with decreased injury time-loss when both negative life change and total life change increased. The results indicate that athletes with more optimism, hardiness or global self-esteem may cope more effectively with life change stress, resulting in reduced injury vulnerability and recovery rates.  相似文献
