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   

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   

The categorisation of swimming start performance with reference to force generation on the main block and footrest components of the Omega OSB11 start blocks

Abstract

Work presented in this paper provides a methodology for categorising swimming start performance based on peak force production on the main block and footrest components of the Omega OSB11 starting block. A total of 46 elite British swimmers were tested, producing over 1000 start trials. Overwater cameras were synchronised to a specifically designed start block that allowed the measurement of force production via two sets of four, tri-axis, force transducers; one set in the main block and one in the footrest. Data were then analysed, segregating trials for gender. Each start was categorised, with respect to the peak force production in horizontal and vertical components, into one of nine categories. Three performance indicators, i.e. block time, take-off velocity and distance of entry, were used to assess whether differences in performance could be correlated with these categories. Results from these data suggest that swimmers generating higher than average peak forces were more likely to produce a better overall start performance than those who produced forces lower than the average, for this population of athletes.  相似文献   

The professional learning needs and priorities of higher-education-based teacher educators in England,Ireland and Scotland     

Gerry Czerniawski  Donald Gray  Ann MacPhail  Yvonne Bain  Paul Conway  Ainat Guberman 《师资教育杂志》2018,44(2):133-148

Against a rapidly changing policy landscape for teacher education, exacerbated by ‘Brexit’ in the UK, findings are presented from an electronic survey of 272 higher-education based teacher educators in England, the Republic of Ireland and Scotland about their experiences of, and priorities for, professional learning. While the data generated were mainly quantitative data, qualitative features were embedded within the survey design. Both types of data have been used to draw out complexities that emerge when exploring a professional group of educators responsible for the preparation of a future generation of teachers. The findings are presented and discussed in relation to the professional demographics of the sample, research expectations placed on them and teacher educators’ priorities for professional learning. Given the unique occupational position of teacher educators, their importance in the quality of teacher education and the lack of formal focus on their professional development, our starting point for teacher educators’ professional development lies in their practice situated and positioned within global, regional, national and local policy contexts.  相似文献

A school wide approach to leading pedagogical enhancement: An Australian perspective     

Joan M. Conway  Dorothy Andrews 《Journal of Educational Change》2016,17(1):115-139

This paper presents how some Australian schools are changing their approaches to leading the teaching and learning in their diverse and multi-characteristic contexts. Experiences of these schools shows that the development of a school wide approach to pedagogy and its implementation needs to be firmly embedded in the leadership of learning. Drawing on recent research conducted in the Sydney Catholic Education Office system in Australia (Crowther et al. in Leading and Managing 18(2):1–33, 2012) there is evidence of relationship between the development and implementation of a school wide approach to pedagogy and student achievement. There is also evidence to support leadership that is based on a mutualistic relationship between teacher leaders and the principal. This paper focuses on the way schools have used their visions and pedagogical frameworks to enhance whole of school quality outcomes. It highlights the power of teacher leaders taking responsibility for pedagogical development and implementation. In addition, it illustrates the power of mutualistic relationships (parallel leadership) when the principal takes responsibility for unleashing and trusting the creative expertise of teacher leaders in line with the role of strategic leadership and management.  相似文献
