Electronic games are popular and many children spend much time on this activity. Here we investigate whether the quantity of time children spend on gaming is related to their social development, making this the first study to examine this relationship in children. We examine prospective relations between time spent gaming and social competence in a community sample of Norwegian 6 year olds (n = 873) followed up at ages 8, 10, and 12, controlling for socioeconomic status, body mass index, and time spent gaming together with friends. Results revealed that greater social competence at both 8 and 10 years predicted less gaming 2 years later and that more age-10 gaming predicted less social competence at age 12 but only among girls.  相似文献   

Developing citizens and communities through youth environmental action     

Tania M. Schusler  Marianne E. Krasny  Scott J. Peters  Daniel J. Decker 《Environmental Education Research》2009,15(1):111-127

Although several studies have examined learning outcomes of environmental action experiences for youth, little is known about the aims motivating practitioners to involve youth in action creating positive environmental and social change, nor how practitioners perceive success. This research explored through phenomenological interviews practitioners’ purposes for using an environmental action approach. Practitioners in this inquiry, who engaged youth in action addressing a range of environmental issues in varied programmatic and community contexts in the US, expressed multifaceted aims motivating their educational practice. Interpretation of practitioners’ stories with respect to their purposes and perceptions of success contributed to a conceptual framework relating environmental action to the development of citizens and sustainable communities. Whereas others have described the stages and learning outcomes of environmental action, this inquiry illustrates the potential of environmental action for concurrently realizing individual and community level impacts.  相似文献   

Identifying high-quality centre-based childcare using quantitative data-sets: what the numbers do and don't tell us     

Marianne Fenech  Naomi Sweller  Linda Harrison 《International Journal of Early Years Education》2010,18(4):283-296

Quantitative approaches to defining and measuring quality in early childhood education and care (ECEC) have provided a key platform for policy development. Yet their strengths and limitations as informants of high-quality ECEC have not been tested. In this study we examine two sources of quantitative data collected over a five-year period for 74 long day care centres: (1) the Early Childhood Environment Rating Scale-Revised and Infant-Toddler Environment Rating Scale instruments which are well-established observational measures; and (2) Australia's nationally administered Quality Improvement and Accreditation System which involves a self-study and validation process. Correspondence over time and across measures was more consistent for the centres identified as providing lower quality ECEC. Variability in ratings of quality was more evident in lower quality centres, whereas high-quality centres showed less variability over time. High quality, however, was less consistently identified across measures. Discussion focuses on the strengths and limitations of these measures of quality, and the implications these have for policy development and future research.  相似文献   

Does local dynamic stability of kayak paddling technique affect the sports performance? A pilot study     

Daniel Hamacher  Tobias Krebs  Guido Meyer  Astrid Zech 《European Journal of Sport Science》2018,18(4):491-496

During competition, kayak athletes must optimally adapt to environmental factors (e.g. wind, waves) to achieve peak performance. However, the ability to adapt to such perturbations has never been assessed in kayak paddling. Therefore, the aim of the current study was to evaluate the local dynamic stability in sports technique of youth sprint kayak athletes. In a cross-sectional study, 14 healthy male athletes were recruited from an elite youth sprint kayak squad. During an incremental kayak ergometer test, mean power, heart rates and local dynamic technique stability of hands, arms, trunk and paddle were registered and the association with the athletes 2000?m free-water times were estimated using mixed models. The 2000?m free-water performance significantly predicted the paddles (p?=?.037) local dynamic stability whereas no association was found for the trunk or the upper extremity kinematics. In conclusion, kayak athletes with high-performance capability over 2000?m paddling depict high local dynamic technique stability. This emphasizes the importance of a stable technique for advanced kayak skills, especially regarding paddling movements.  相似文献   

The “Species” Concept as a Gateway to Nature of Science     

Jorun Nyléhn  Marianne Ødegaard 《Science & Education》2018,27(7-8):685-714

The nature of science (NOS) is a primary goal in school science. Most teachers are not well-prepared for teaching NOS, but a sophisticated and in-depth understanding of NOS is necessary for effective teaching. Some authors emphasize the need for teaching NOS in context. Species, a central concept in biology, is proposed in this article as a concrete example of a means for achieving increased understanding of NOS. Although species are commonly presented in textbooks as fixed entities with a single definition, the concept of species is a highly discussed one in the science and the philosophy of biology. A multitude of species concepts exist, reflecting both the views and interests of researchers and their utility in different organism groups. The present study serves to address the following questions: How do textbooks in Norwegian primary and lower secondary schools present the concept of species? Can inquiries into the concept of “species” serve to highlight aspects of NOS? A review of the available literature on species and species concepts in school is also performed. In the schoolbooks, the biological species concept is commonly used as the main definition, whereas the morphological species concept is represented by additional remarks of similarity. The potential and pitfalls of using the species concept for teaching NOS are discussed, with NOS being discussed both as a family resemblance concept and as a consensus list. Teacher education is proposed as a starting point for inducing a more sophisticated view of biology into schools.  相似文献   

The interplay of cognitive and relational social capital dimensions in university-industry collaboration: Overcoming the experience barrier     

Marianne Steinmo  Einar Rasmussen 《Research Policy》2018,47(10):1964-1974

The use of university-industry collaboration in the innovation process is viewed as a major driver of firm competitiveness. The organizational dynamics underlying successful external relationships, however, remain poorly understood. Using longitudinal case studies of 15 innovation projects, we examine how firms with varying degrees of experience in collaborating with universities and public research organizations rely on different social capital dimensions to achieve successful collaborations. We find that experienced firms establish external collaborations on the basis of cognitive social capital, but this basis is reinforced by relational social capital over time. Conversely, less experienced firms initially base their university collaborations on relational social capital, which is reinforced by cognitive social capital over time. Based on these findings, we theorize on the interplay of different dimensions of social capital in university-industry collaborations over time. Our study has important implications for the management of collaborative innovation projects. In particular, it provides guidance to enable less experienced firms to develop successful collaborations with university partners.  相似文献   

Sozialer Status und Spendenverhalten Ehrenamtlicher in Sportvereinen     

Eike Emrich  Martin Hämmerle  Christoph Behrens  Tim Meyer  Christian Pierdzioch 《Sportwissenschaft》2018,48(4):560-572

While much research has been done to analyze whether socioeconomic status influences prosocial behavior in the form of donations, no consensus has yet emerged in the relevant literature. We contribute to this research by studying, based on a dataset from a questionnaire of volunteers of sports clubs in Palatinate (part of Rhineland–Palatinate, Germany) whether social status affects donations. We measured social status of volunteers of sports clubs along the dimensions income, vocation, education and we considered status crystallization. Results showed that social status has a positive effect on the likelihood of donations. We report similarities and differences across different categories of donations (donations to one’s own sports club, to other clubs, to aid projects, and political parties).  相似文献   

Pädagogische Begleitung: Handlungsform und Systemmerkmal     

Dieter Nittel  Nikolaus Meyer 《Zeitschrift für Erziehungswissenschaft》2018,21(5):1063-1082

This contribution aims to lay down the theoretical potential of accompaniment as a phenomenon and developing this point further from a pedagogical perspective. The core assumption is that accompaniment represents both a pedagogically relevant phenomenon of action as well as an essential characteristic of the system. In this sense, accompaniment can be understood as creating a possibility for looking at phenomena of education on a micro and a macro level. Thus, the assumption follows that a central signature of the social system – namely that of inclusion – has already been incorporated by the pedagogically organized system of lifelong learning a long time ago. This finding has far-reaching consequences for levelling the hierarchy between different layers of the education and learning systems.  相似文献
