Use of dual-task methodology for skill assessment and development: examples from rugby league   总被引：2，自引：1，他引：1

We assessed the attentional demands of drawing and passing in rugby league players and investigated the effects of single-task and dual-task training on the acquisition, retention, and transfer of skill in these athletes. In Study 1, high-skilled and lesser-skilled rugby league players performed a standardized 2-on-1 drill under single-task (primary skill in isolation) and dual-task (primary skill while performing a secondary verbal tone recognition task) conditions. No differences were detected in primary task performance between groups, although the performance of the high-skilled players was more resistant to skill decrement under dual-task conditions. In Study 2, high-performance rugby league players were randomly allocated to either a single-task or dual-task training group. Each group underwent 8 weeks of training between the pre- and post-test sessions. While the mean improvement for draw and pass proficiency under dual-task conditions in the dual-task training group was greater than in the single-task training group (10.0% vs. 2.3%), the differences, while providing a moderate effect size (d = 0.57), were not statistically significant. These results suggest that the attentional demands of drawing and passing are reduced in high-skilled rugby league players compared with their lesser-skilled counterparts. In addition, compared with single-task training, dual-task training appears to improve the ability to perform dual-task draw and pass tasks (possibly through an improvement in time-sharing skills). Further studies are required to verify the efficacy of dual-task training as a training stimulus.  相似文献   

The role of athlete narcissism in moderating the relationship between coaches' transformational leader behaviors and athlete motivation     

Arthur CA  Woodman T  Ong CW  Hardy L  Ntoumanis N 《运动与训练心理学杂志》2011,33(1):3-19

Leadership research that examines follower characteristics as a potential moderator of leadership effectiveness is lacking. Within Bass's (1985) transformational leadership framework, we examined follower narcissism as a moderator of the coach behavior-coach effectiveness relationship. Youth athletes (male = 103, female = 106) from the Singapore Sports Academy (mean age = 14.28, SD = 1.40 years) completed the Differentiated Transformational Leadership Inventory (Callow, Smith, Hardy, Arthur, & Hardy, 2009), the Narcissistic Personality Inventory (Raskin & Terry, 1988), and indices of follower effort. Multilevel analyses revealed that athlete narcissism moderated the relationship between fostering acceptance of group goals and athlete effort and between high performance expectations and athlete effort. All the other transformational leader behaviors demonstrated main effects on follower effort, except for inspirational motivation.  相似文献

Formula for Uncertainty     

Tim Lee 《British Journal of Special Education》1991,18(3):100-102

How LEAs are measuring and allocating resources for special educational needs varies widely. Yet their formulae for doing so are likely to make the difference between enabling pupils with special needs to progress in their learning and, conversely, reducing the support they may need. Tim Lee, research fellow, Centre for the Analysis of Social Policy, Bath University, reports on the latest surveys of LEAs' funding policies.  相似文献

The relationship between qualified personnel and self-reported implementation of recommended physical education practices and programs in U.S. schools     

Davis KS  Burgeson CR  Brener ND  McManus T  Wechsler H 《Research quarterly for exercise and sport》2005,76(2):202-211

The authors analyzed data from the School Health Policies and Programs Study 2000 to assess the associations between the presence of a district physical education coordinator and district-level physical education policies and practices recommended by federal government agencies and national organizations. The authors also examined the relationship between teacher qualifications and staff development related to physical education and self-reported implementation of recommended teachingpractices. District-level data were collected by self-administered mail questionnaires from a nationally representative sample of school districts. Classroom-level data were collected by computer-assisted personal interviews with teachers of randomly selected classes in elementary schools and randomly selected required physical education courses in middle/junior high and senior high schools. Nearly two thirds (62.2%) of districts had a physical education coordinator, and those were generally more likely than other districts to report having policies and practices that corresponded with national recommendations for high-quality physical education programs. More than two thirds of teachers (66.9%) met the criteria for teacher qualifications based on their education and certification. These teachers were more likely than others to report use of certain recommended physical education teaching practices. Teachers who participated in staff development also were more likely to use recommended teaching practices in their classrooms. Using a district physical education coordinator and teachers with appropriate qualifications as well as offering staff development opportunities on physical education may enhance school physical education programs.  相似文献   

Thinking it through: a study of how pre-service teachers respond to children who present with possible mental health difficulties     

David Armstrong  Deborah Price  Tim Crowley 《Emotional and Behavioural Difficulties》2013,18(4):381-397

Teachers are key professionals in responding to children and adolescents with possible mental health difficulties and who exhibit social, emotional or behavioural difficulties in the classroom. Health and education policy increasingly positions teachers as vital agents in connecting mental health services with affected young people. A growing corpus of research, however, questions practitioners’ capacity to undertake this important role, particularly given the limited space afforded to content around mental health in pre-service teacher education. This paper reports on a qualitative case study, conducted in an Australian context, investigating pre-service teacher responses to five vignettes of young people presenting behaviours indicative of possible mental health difficulties. In light of educator expectations to identify and appropriately respond to mental health difficulties, this study discloses the need for explicit, structured mental health guidance which form a discrete, core ‘knowledge base’ of teacher education. Patterns in data, analysed in light of policy literature, also suggest the value inherent in advocating open-minded, non-judgemental and collegial professional responses. Further research opportunities highlighted include a systematic review of current provision around mental health in pre-service teacher education programmes.  相似文献
