田径技术教学中学生产生错误动作的原因及运动技能能力提高的干扰因素

对运动技能形成的传统观点进行了重新认识,对田径运动关于运动技能形成的三个阶段之间的关系提出了质疑.结合运动技能形成过程中的生理、心理特点,分析了导致学生学习技能过程中产生错误动作的原因.认为:学生学习技能过程中,如果静态与动态概念不清、运动负荷强度过大、心理定向错误、基本运动能力差,必然导致错误动作的出现.这四个方面也是运动技能能力提高的随时干扰因素.     

“最佳二传竞技水平”的概念模型开发及测评方法

为了克服“二传竞技水平”测评指标的选用及量化难度大的困难;为了提供一套科学、客观、实用的多指标测评体系,以“三论归一学说”为理论指导,把二传的本质是“变换器”作为测评体系的开端,以开发“最佳二传竞技水平”的概念为基础,以具有权威性和代表性的文献为依据,建立了“最佳二传竞技水平”的概念模型,并结合测评原则推演出模型指标体系。指标体系经理论论证、专家验证、实践检验后证明：满足测量学的“三性”要求,不仅能为参赛二传手的二传竞技水平排序,而且其量化分析报告能为二传训练提供指导性的反馈信息。

More Than Just a Student Voice: Facilitating Student Leadership Development Through the Library Student Liaison Program

This article explores how the library-student liaison program at Eastern Washington University (EWU) Libraries has evolved into an opportunity for students to develop leadership skills. Originally designed to foster better communication between the EWU Libraries and students enrolled at the university, we recognized that the process of achieving established goals for the program provided a vehicle for students' leadership-skill development. To facilitate the leadership process, librarians employed the Social Change Model. Designed specifically for college students, this model engages the student to develop individual capacities to strengthen group activities that foster positive changes in the community and society.     

Creating Better Learners Through Learning Science: A Sample of Methods

This article proposes the incorporation of learning science into the programming and operation of public libraries. Learning science, a multidisciplinary field spanning cognitive science, psychology, neuroscience, economics, anthropology, and linguistics, has identified proven methods for enhancing learning at any age. The article highlights some of the tools and insights that are most relevant to libraries in their role as centers for informal learning.

Childhood Physical Fitness and Performance as Predictors of High School Sport Participation

ABSTRACT

Participation in youth sport is positively associated with physical fitness and performance. The purpose of the current study was to examine if physical fitness measures during childhood and early adolescence predicted high school sport participation. Participants included youth in the Michigan State University Motor Performance Study. Measures consisted of the endurance shuttle run, Wells sit-and-reach, jump and reach, standing long jump, agility shuttle run and 30-yard dash. Individual, generalized estimating equation models were used to estimate the association between each measure and the odds of participating in high school sport. For both sexes, the endurance shuttle run and agility shuttle run were related to sport participation. For boys only, the long jump and 30-yard dash were also associated with sport participation. Better physical fitness and performance across several dimensions in childhood, including those related to motor skills, enhanced the likelihood of sport participation in high school.     

Teaching skills of student teachers: Calibration of an evaluation instrument and its value in predicting student academic engagement

Student teachers are expected to develop their teaching skills sooner and more rapidly. However, a sound evaluation instrument that can be used to diagnose and monitor the skilfulness level to aid formative assessment of student teachers is still limited. This article is aimed to calibrate and validate a teaching skill evaluation instrument for use in secondary education. A total of 264 student teachers in the Netherlands participated in the study. Rasch and multilevel analyses were used. Results suggest that the evaluation instrument meets the restrictive assumptions of the Rasch model and has predictive value for academic engagement. This adds validation evidence and justifies the calibration of the evaluation instrument to be used for monitoring the development of teacher's teaching skills.

Cross-Cultural Adaptation and Psychometric Properties of the Portuguese Version of the Life Skills Scale for Sport

ABSTRACT

This research adapted the Life Skills Scale for Sport (LSSS) into Portuguese and provided evidence for its construct validity. Study 1 included four translators and five academics who developed a Portuguese version of the LSSS (P-LSSS). During this study, evidence for the content and substantive aspects of construct validity was provided using an expert panel and 25 sports participants. Study 2 included 413 participants that completed the P-LSSS. Within this study, evidence for the structural aspect of construct validity was provided via factor analyses. Study 3 included 134 participants who completed the P-LSSS and a measure of motivation. This study provided evidence for the external aspect of construct validity, with results showing more self-determined motivation had positive relationships with participant’s life skills development. Overall, our findings provided evidence for the construct validity of P-LSSS scores. Researchers and practitioners can use the P-LSSS to assess life skills development within sports participants.
