Reliability and construct validity of soccer skills tests that measure passing, shooting, and dribbling   总被引：1，自引：1，他引：0  

Russell M  Benton D  Kingsley M 《Journal of sports sciences》2010,28(13):1399-1408

In this study, we examined the reliability and construct validity of new soccer skills tests. Twenty soccer players (10 professional and 10 recreational) repeated trials of passing, shooting, and dribbling skills on different days. Passing and shooting skills required players to kick a moving ball, delivered at constant speed, towards one of four randomly determined targets. Dribbling required players to negotiate seven cones over 20?m. Each trial consisted of 28 passes, 8 shots, and 10 dribbles. Ball speed, precision, and success were determined for all tests using video analysis. Systematic bias was small (<9% in all measures) and all outcome measures were similar between trials. Test-retest reliability statistics were as follows: ball speed (passing, shooting, dribbling; coefficient of variation [CV]: 6.5%, 6.9%, 2.4%; ratio limits of agreement [RLOA]: 0.958?×/÷ 1.091, 0.990?×/÷ 1.107, 0.993?×/÷ 1.039), precision (passing, shooting, dribbling; CV: 10.0%, 23.5%, 4.6%; RLOA: 0.956?×/÷ 1.147, 1.030?×/÷ 1.356, 1.000?×/÷ 1.068), and success (passing, shooting, dribbling; CV: 11.7%, 14.4%, 2.2%; RLOA: 1.017?×/÷ 1.191, 0.913?×/÷ 1.265, 0.996?×/÷ 1.035). Professional players performed better than recreational players in at least one outcome measure for all skills. These findings demonstrate the reliability and validity of new soccer skill protocols.  相似文献

ABSTRACT

This cluster randomized controlled trial (trial-number #) compares effects of two school-based physical activity interventions (aerobic vs. cognitively-engaging) on reading, mathematics, and spelling achievement; and whether effects are influenced by volume of moderate-to-vigorous physical activity and baseline achievement. Twenty-two primary schools participated, where a third and fourth grade class were randomly assigned to the intervention or control group. Intervention groups were randomly assigned to a 14-week aerobic or cognitively-engaging intervention, receiving four physical education lessons a week. Control groups followed their regular physical education program. Academic achievement of 891 children (mean age 9.17 years, 49.4% boys) was assessed with standardized tests before and after the interventions. Post-Test academic achievement did not significantly differ between intervention groups and control group. A higher volume of moderate-to-vigorous physical activity resulted in better post-test mathematics achievement in both intervention groups, and post-test spelling achievement in the cognitively engaging intervention group. Compared to the control group, lower achievers in reading performed better in reading after the cognitively-engaging intervention. A combination of moderate-to-vigorous physical activity and cognitively-engaging exercises seems to have the most beneficial effects. Future intervention studies should take into account quantitative and qualitative aspects of physical activity, and children’s baseline academic achievement.  相似文献   

Examining the practice of a reading-to-speak test task: anxiety and experience of EFL students     

Heng-Tsung Danny Huang  Shao-Ting Alan Hung 《Asia Pacific Education Review》2010,11(2):235-242

In the literature, little research has hitherto been conducted to examine the implementation of integrated speaking test tasks. This study, in response, set out to compare the anxiety induced by a reading-to-speak task and the anxiety produced by a speaking-only task and to explore students’ experiences of taking the reading-to-speak task. Forty-seven Taiwanese EFL learners completed a reading-to-speak task and a speaking-only task, filled out a state anxiety inventory twice, and responded to an open-ended questionnaire. The paired t-test revealed that the reading-to-speak task produced a statistically comparable degree of anxiety as the speaking-only task, possibly owing to the additional anxiety inflicted by its reading component. The qualitative analysis disclosed that students preferred the reading-to-speak task to the speaking-only task, even though it provoked additional anxiety, featured additional challenges, and entailed different response strategies. In light of these findings, implications are proposed for oral assessment research and EFL oral assessment practices.  相似文献   

The research core of the knowledge management literature   总被引：1，自引：0，他引：1

A bibliometric analysis and a content analysis were conducted to explore the nature of the knowledge management literature. For the bibliometric analysis, three levels of Bradford analysis were used to examine the shape of the knowledge management literature based on 21,596 references from 2771 source publications. Each of the three analyses conformed to the typical curve of the Bradford distribution. For the content analysis, the texts of 630 knowledge management articles were analyzed to address the question of what research methodologies are used in the knowledge management literature. It was found that 27.8 percent of knowledge management-related articles in knowledge management journals used no identifiable research method. Of the remaining 455 refereed articles, 60 percent employed mainstream social sciences research methodologies. The remaining 40 percent of the articles using an identifiable methodology were characterized by the use of “provisional methods” that appeared to substitute for more formally defined or scientifically based research methodologies.  相似文献   

Adult and community education in complex societies: reconsidering critical perspectives     

Danny Wildemeersch 《International Journal of Lifelong Education》2013,32(6):821-831

In this contribution, I explore how critical pedagogical perspectives can inspire adult and community education practices. The central argument is that today, in contrast with the heydays of emancipatory practices and theories, the classical critical approaches need reconsideration. The paper explores how these approaches sometimes have a stultifying effect on the participants in practice. In line with the French philosopher Rancière, a perspective is explored that departs from emancipated participants rather than from participants in need of emancipation. The theoretical investigation is inspired by reflections on art practices that struggle with similar questions on emancipation as the field of adult and community education.  相似文献   

Supervisor Impression Management: Message Content and Channel Effects on Impressions     

Catherine Y. Kingsley Westerman 《Communication Studies》2013,64(5):585-601

The current study focuses on the delivery of negative feedback and how supervisors can accomplish that delivery while maintaining their own image and their employees' face. We look at delivery of feedback with and without face-saving messages through two different channels: face-to-face (FtF) and email. Results indicate that the inclusion of face-saving messages had relatively consistent positive effects on a variety of employees' impressions of supervisors. Channel was found to interact with message content to impact perceived face threat of a message and the perception of the supervisor's appropriateness. These findings are discussed in terms of theoretical and practical applications, as are limitations and directions for future research.  相似文献   

The construction and validation of the test of graphing in science (togs)     

Danny L. McKenzie  Michael J. Padilla 《科学教学研究杂志》1986,23(7):571-579

The objective of this project was to develop a multiple choice test of graphing skills appropriate for science students from grades seven through twelve. Skills associated with the construction and interpretation of line graphs were delineated, and nine objectives encompassing these skills were developed. Twenty-six items were then constructed to measure these objectives. To establish content validity, items and objectives were submitted to a panel of reviewers. The experts agreed over 94% of the time on assignment of items to objectives and 98% on the scoring of items. TOGS was first administered to 119 7th, 9th, and 11th graders. The reliability (KR-20) was 0.81. Poorly functioning items were rewritten based on the item difficulty and discrimination data. The revised version of the test was given to 377 7th through 12th grade students. Total scores ranged from 2 to 26 correct (X = 13.3, S.D. = 5.3). The reliability (KR-20) was 0.83 for all subjects and ranged from 0.71 for eighth graders to 0.88 for ninth graders. Point biserial correlations showed 24 of the 26 items above 0.30 with an average value of 0.43. It was concluded from this and other data that TOGS was a valid and reliable instrument for measuring graphing abilities.  相似文献
