The development of the classroom social climate during the first months of the school year

In this study the mean stability of classroom social climates during the first months of the school year and the deviation of individual classrooms (N = 48) and students (N = 1208) from this general trend were investigated by taping students’ interpersonal perceptions of their teachers. Multilevel growth modeling was used to identify the average development of the classroom social climate and between classroom and student differences in terms of this development. While significant differences between classrooms and students were found, these differences were rather stable over time. Most classrooms showed a slightly u-shaped trajectory. In only very few classrooms the quality of the social climate had increased at the end of the research period as compared to the very first lesson. Differences in the development between classrooms were associated to the emotional distance between teacher and students during the first lesson of the school year.

Use of dual-task methodology for skill assessment and development: examples from rugby league

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.     

Nutrition for winter sports

Winter sports are played in cold conditions on ice or snow and often at moderate to high altitude. The most important nutritional challenges for winter sport athletes exposed to environmental extremes include increased energy expenditure, accelerated muscle and liver glycogen utilization, exacerbated fluid loss, and increased iron turnover. Winter sports, however, vary greatly regarding their nutritional requirements due to variable physiological and physique characteristics, energy and substrate demands, and environmental training and competition conditions. What most winter sport athletes have in common is a relatively lean physique and high-intensity training periods, thus they require greater energy and nutrient intakes, along with adequate food and fluid before, during, and after training. Event fuelling is most challenging for cross-country skiers competing in long events, ski jumpers aiming to reduce their body weight, and those winter sport athletes incurring repeated qualification rounds and heats. These athletes need to ensure carbohydrate availability throughout competition. Finally, winter sport athletes may benefit from dietary and sport supplements; however, attention should be paid to safety and efficacy if supplementation is considered.     

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

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.     

德语国家普通教学论的核心命题与时代课题

德语国家(德国、奥地利以及瑞士)普通教学论历史悠久,对整个教育学科的建立与发展意义重大。普通教学论作为系统性、普遍性的教学理论,强调自身理论的主体性、师生对话的意义建构、教师清晰的指导与管理、教学的反思性实践。新的时代背景下,德语国家普通教学论的发展既坚守传统,又积极转向,系统分析其优劣特质可以发现:相关理论一方面具有整体性、独特性、指导性、反思性、规范性等特征;另一方面也面临着诸如学科地位下滑、缺乏实证研究支撑、自身理论发展缓慢、缺乏课程研究支持等问题。为应对信息技术时代学校教育的异质性、融合教育、移民教育、健康教育、数字化教育等新兴教学情境,相关研究呈现出新的发展趋势,转向"技术支持下团队合作"、"多主体协同建构"、"制定数字化教学新标准"。     

Formula for Uncertainty

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.
