ABSTRACT

The objective of this study was to create a valid, self-reported, game-specific soccer competence scale. A structural model of perceived competence, performance measures and motivation was tested as the basis for the scale. A total of 1321 soccer players (261 females, 1060 males) ranging from 12 to 15 years (13.4 ± 1.0 years) participated in the study. They completed the Perceived Game-Specific Soccer Competence Scale (PGSSCS), self-assessments of tactical skills and motivation, as well as technical and speed and agility tests. Results of factor analyses, tests of internal consistency and correlations between PGSSCS subscales, performance measures and motivation supported the reliability and validity of the PGSSCS. The scale can be considered a suitable instrument to assess perceived game-specific competence among young soccer players.  相似文献   

Development of perceived competence,tactical skills,motivation, technical skills,and speed and agility in young soccer players

ABSTRACT

The objective of this 1-year, longitudinal study was to examine the development of perceived competence, tactical skills, motivation, technical skills, and speed and agility characteristics of young Finnish soccer players. We also examined associations between latent growth models of perceived competence and other recorded variables. Participants were 288 competitive male soccer players ranging from 12 to 14 years (12.7 ± 0.6) from 16 soccer clubs. Players completed the self-assessments of perceived competence, tactical skills, and motivation, and participated in technical, and speed and agility tests. Results of this study showed that players’ levels of perceived competence, tactical skills, motivation, technical skills, and speed and agility characteristics remained relatively high and stable across the period of 1 year. Positive relationships were found between these levels and changes in perceived competence and motivation, and levels of perceived competence and speed and agility characteristics. Together these results illustrate the multi-dimensional nature of talent development processes in soccer. Moreover, it seems crucial in coaching to support the development of perceived competence and motivation in young soccer players and that it might be even more important in later maturing players.  相似文献

Abstract

The aim of this study was to determine potential relationships between anthropometric parameters and athletic performance with special consideration to repeated-sprint ability (RSA). Sixteen players of the senior male Qatar national soccer team performed a series of anthropometric and physical tests including countermovement jumps without (CMJ) and with free arms (CMJwA), straight-line 20 m sprint, RSA (6 × 35 m with 10 s recovery) and incremental field test. Significant (P < 0.05) relationships occurred between muscle-to-bone ratio and both CMJs height (r ranging from 0.56 to 0.69) as well as with all RSA-related variables (r < –0.53 for sprinting times and r = 0.54 for maximal sprinting speed) with the exception of the sprint decrement score (S_dec). The sum of six skinfolds and adipose mass index were largely correlated with S_dec (r = 0.68, P < 0.01 and r = 0.55, P < 0.05, respectively) but not with total time (TT, r = 0.44 and 0.33, P > 0.05, respectively) or any standard athletic tests. Multiple regression analyses indicated that muscular cross-sectional area for mid-thigh, adipose index, straight-line 20 m time, maximal sprinting speed and CMJwA are the strongest predictors of S_dec (r² = 0.89) and TT (r² = 0.95) during our RSA test. In the Qatar national soccer team, players’ power-related qualities and RSA are associated with a high muscular profile and a low adiposity. This supports the relevance of explosive power for the soccer players and the larger importance of neuromuscular qualities determining the RSA.  相似文献

Cinematic Rendering in Anatomy: A Crossover Study Comparing a Novel 3D Reconstruction Technique to Conventional Computed Tomography     

Johannes S. Binder  Michael Scholz  Stephan Ellmann  Michael Uder  Robert Grützmann  Georg F. Weber  Christian Krautz 《Anatomical sciences education》2021,14(1):22-31

Integration of medical imaging into preclinical anatomy courses is already underway in many medical schools. However, interpretation of two-dimensional grayscale images is difficult and conventional volume rendering techniques provide only images of limited quality. In this regard, a more photorealistic visualization provided by Cinematic Rendering (CR) may be more suitable for anatomical education. A randomized, two-period crossover study was conducted from July to December 2018, at the University Hospital of Erlangen, Germany to compare CR and conventional computed tomography (CT) imaging for speed and comprehension of anatomy. Sixteen students were randomized into two assessment sequences. During each assessment period, participants had to answer 15 anatomy-related questions that were divided into three categories: parenchymal, musculoskeletal, and vascular anatomy. After a washout period of 14 days, assessments were crossed over to the respective second reconstruction technique. The mean interperiod differences for the time to answer differed significantly between the CR–CT sequence (−204.21 ± 156.0 seconds) and the CT–CR sequence (243.33 ± 113.83 seconds; P < 0.001). Overall time reduction by CR was 65.56%. Cinematic Rendering visualization of musculoskeletal and vascular anatomy was higher rated compared to CT visualization (P < 0.001 and P = 0.003), whereas CT visualization of parenchymal anatomy received a higher scoring than CR visualization (P < 0.001). No carryover effects were observed. A questionnaire revealed that students consider CR to be beneficial for medical education. These results suggest that CR has a potential to enhance knowledge acquisition and transfer from medical imaging data in medical education.  相似文献   

Emergence and evolution of informal roles during a canoe expedition

This exploratory study was conducted to illuminate aspects relevant to the emergence and evolution of informal roles in a group during a canoe expedition. Following tenets of ethnography, the first author collected observational and interview (conversational and focus group) data while participating as a member of the expedition. Three general dimensions were revealed with regards to emerging and evolving informal roles: context aspects; role occupant aspects; and group member aspects. Informal roles were found to be important structural components which contributed to group productivity and harmony. Findings are discussed in relation to the broader literature while questions are raised regarding how informal roles have been conceptualized. Implications include considering how informal roles relate to individual (e.g. satisfaction) and group (e.g. cohesion) level constructs and how outdoor leaders may benefit from understanding how informal roles emerge and evolve.  相似文献   

Stichwort: Transfer und Transferforschung im Bildungsbereich     

Prof. Dr. Cornelia Gräsel 《Zeitschrift für Erziehungswissenschaft》2010,13(1):7-20

“Transfer of innovation” is understood in education science as concerned with the dissemination of scientifically based innovations in educational systems. This contribution will begin with a more precise definition of the term transfer, an overview of the current state of research and on which factors influence the successful dissemination of innovations in educational systems. In the second part, four strategies will be presented which enable the dissemination of scientific evidence into practical settings. Here we will compare strategies which have been used within the context of pilot programmes in Germany with internationally established approaches. These international approaches are more output-orientated and, therefore, look to the effects of innovations on pupils—especially with respect to performance development. The comparison contrasts classic top-down with evidence-based strategies and participative strategies with design-research approaches. Finally, we discuss the role given to educational research within these strategies.  相似文献

A mixed-methods evaluation of the longer-term implementation and utility of a teacher classroom management training programme in Irish primary schools     

Yvonne Leckey  Lynda Hyland  Gráinne Hickey  Anne Lodge  Paul Kelly  Tracey Bywater 《Irish Educational Studies》2016,35(1):35-55

Inappropriate, aggressive and disruptive behaviour in the classroom can be detrimental to child and teacher well-being. This study involved a longer-term evaluation of the Incredible Years Teacher [Classroom Management] programme (IYTP) undertaken mainly within disadvantaged schools in south-west Ireland. The IYTP is designed to strengthen teacher classroom management competencies. Eleven teachers, who had previously participated in a group-randomised control trial (RCT), took part in a 12-month post-baseline follow-up assessment. Psychometric and observational measures were administered to assess teachers when interacting with children (n?=?217) in their classes. Qualitative data were collected from a sub-sample of teachers to explore their perceptions of programme impact and utility. The quantitative results showed some significant improvements in teachers’ classroom management, although few changes were recorded on teacher-child observation measures. Qualitative findings indicated continued implementation of proactive disciplining strategies and higher levels of teacher self-efficacy. These results suggest, albeit tentatively in view of the study limitations, that the IYTP can benefit teacher classroom management, as well as teacher well-being, particularly within disadvantaged schools where behavioural problems tend to be more prevalent. The IYTP could prove useful in improving teacher competencies and the classroom environment in the longer term, although a need for further research is indicated.  相似文献   

An international literature review of 1:1 computing in schools     

M. Sirajul Islam  Åke Grönlund 《Journal of Educational Change》2016,17(2):191-222

This paper is based on a systematic literature review relevant to classroom integration of computer technologies in schools. The purpose of this review is to gain an accumulated view of uses, impacts and implementations of 1:1 computing initiatives for school children. Unlike previous reviews this study is not limited to certain countries or certain technologies. It includes any devices used in 1:1 computing (not just the PC), and schools worldwide. The paper investigates the themes being researched regarding 1:1 use in schools as well as exhibits some which are not yet being researched but should be important to investigate. The study finds mixed results including positive, negative and no-effects. The findings of this review are expected to be useful both for academics as well as policy makers for gaining insights for further research and successful educational policy reforms.  相似文献
