Carson V  Spence JC  Cutumisu N  Boule N  Edwards J 《Research quarterly for exercise and sport》2010,81(4):392-399

Little research has examined seasonal differences in physical activity (PA) levels among children. Proxy reports of PA were completed by 1,715 parents on their children in Edmonton, Alberta, Canada. Total PA (TPA) minutes were calculated, and each participant was classified as active, somewhat active, or inactive. Logistic regression models were conducted to examine associations between PA status and seasons. Significant seasonal differences were observed for TPA, weekday PA, weekend PA, and active play. Children were significantly more likely to be physically active in the summer and spring and somewhat physically active in the summer and fall, relative to winter Children living in cold climates are less likely to be physically active in the winter.  相似文献

A choice theory teaching and learning model for working with children of prisoners     

Oliver W. Edwards 《Educational Psychology in Practice》2009,25(3):259-270

The prison population has increased substantially in countries around the world and significant numbers of these prisoners are parents. Children of prisoners experience separation from the imprisoned parent. The separation and precursors to the separation often diminish these children's social‐emotional and educational well‐being. In this paper, the social‐emotional and educational functioning of children of prisoners is examined. Additionally, choice theory is described as a relevant theoretical teaching and learning model to facilitate the children's school‐related functioning.  相似文献   

Developmental co‐ordination disorder (DCD): more than just a movement difficulty     

Amanda Kirby  David Sugden  Lisa Edwards 《Journal of Research in Special Educational Needs》2010,10(3):206-215

Developmental co‐ordination disorder (DCD) also known as dyspraxia, is characterised by severe impairment of movement that has a detrimental effect on activities of daily living. This impairment of movement can be the result of poor planning or execution during an action. An assessment for DCD usually comprises of a standardised test for movement skills and clinical observations, but an assessment may not always consider both planning and/or execution components. This study used an ecologically valid task to examine how typically developing children compared with children with DCD plan and execute their movements in response to a novel movement challenge. Children were asked to cross a ‘river’ using as few ‘stepping stones’ (carpet tiles) as possible without falling in. The study measured a number of variables in order to construct a profile of the child's ability to plan and execute movements, including pattern and consistency of movement, and distance travelled by each child, as well as the ability to formulate and correct their plan. The results of this pilot study showed both differences and similarities between the two groups, with the DCD group showing more difficulties in planning, executing and in correcting their movements, as well as being more inconsistent in their movement patterns. The results are discussed in terms of the need for multiple measures for a complete assessment of a child, the implications for educational practice and the potential of an additional clinical tool to aid intervention in children with DCD.  相似文献   

Inter‐professional work and expertise: New roles at the boundaries of schools     

Anne Edwards  Ingrid Lunt  Eleni Stamou 《British Educational Research Journal》2010,36(1):27-45

The findings discussed here are based on five case studies and a small survey (n = 46) of how secondary schools are responding to demands that they collaborate with other services to intervene to prevent the social exclusion of children and young people. The case studies revealed a new space of action opening up around schools where practices were being shaped by ‘welfare managers’ who were employed by schools and were undertaking responsive work with vulnerable children and young people and the other services who were also supporting them. At the same time heads of year and/or heads of school and form tutors were increasingly focusing on children's achievement in school. The changes in roles and responsibilities were encouraged by workforce remodelling and changes in criteria for teachers’ salaries. However, focusing primarily on the work undertaken by the welfare managers, the article draws on cultural‐historical activity theory analyses of relational agency and distributed expertise to question whether welfare managers can undertake the work required in the new space of action without attention to the development of their core expertise.  相似文献   

Supply issues for science academics in Australia: now and in the future     

Daniel Edwards  T. Fred Smith 《Higher Education》2010,60(1):19-32

Australia, like the rest of the developed world, is in the midst of dealing with notable issues related to the age structure of its academic workforce. These issues are widespread and have been articulated in the Australian context most comprehensively by Hugo (2008). This paper investigates issues with demographic change and other key factors related to the desirability of a science or mathematics academic career within Australian universities. It draws on the findings of a research project undertaken in 2008 for the Department of Education, Employment and Workplace Relations. The findings show that while demographic issues are not as dire for science academics compared to the entire sector, issues relating to tenure, workload and retaining young science academics in Australia are a threat to the long-term sustainability of science faculties in Australian universities.  相似文献   

Observing response processes with eye tracking in international large-scale assessments: evidence from the OECD PIAAC assessment     

Bryan Maddox  Andrew P. Bayliss  Piers Fleming  Paul E. Engelhardt  S. Gareth Edwards  Francesca Borgonovi 《European Journal of Psychology of Education - EJPE》2018,33(3):543-558

This paper reports on a pilot study that used eye tracking techniques to make detailed observations of item response processes in the OECD Programme for the International Assessment of Adult Competencies (PIAAC). The lab-based study also recorded physiological responses using measures of pupil diameter and electrodermal activity. The study tested 14 adult respondents as they individually completed the PIAAC computer-based assessment. The eye tracking observations help to fill an ‘explanatory gap’ by providing data on variation in item response processes that are not captured by other sources of process data such as think aloud protocols or computer-generated log files. The data on fixations and saccades provided detailed information on test item response strategies, enabling profiling of respondent engagement and response processes associated with successful performance. Much of that activity does not include the use of the keyboard and mouse, and involves ‘off-screen’ use of pen and paper (and calculator) that are not captured by assessment log-files. In conclusion, this paper points toward an important application of eye tracking in large-scale assessments. This includes insights into response processes in new domains such as adaptive problem-solving that aim to identify individuals’ ability to select and combine resources from the digital and physical environment.  相似文献   

The national politics of educational advocacy in the context of global governance: international funding and support for civil society engagement in Cambodia     

D. Brent Edwards Jr.  Willian C. Brehm  Inga Storen 《Compare》2018,48(2):171-188

This paper examines the Civil Society Education Fund’s (CSEF) impact on the non-governmental organisation education partnership (NEP) in Cambodia. With financial backing from the World Bank and the Fast Track Initiative, the CSEF is an initiative that is managed internationally by the Global Campaign for Education. Its goal is to help national networks of non-governmental organizations participate in education decision-making and to serve as a watchdog for progress related to internationally agreed upon goals. Through the CSEF, the deployment of various strategies, and other external factors, the NEP was able to able to achieve recognition, legitimacy and influence at the national level. However, the NEP has had to balance working with the state and working for the state. This case study highlights strategies used by civil society actors to engage state actors, the efficacy of international support, and the conflicts inherent in both.  相似文献   

Leveraging community sport organizations to promote community capacity: Strategic outcomes,challenges, and theoretical considerations     

Gareth J. Jones  Michael B. Edwards  Jason N. Bocarro  Kyle S. Bunds  Jordan W. Smith 《Sport Management Review》2018,21(3):279-292

Community sport organizations (CSOs) provide valuable contexts for promoting community development. These initiatives are most effective when they involve local stakeholders in the process of development. A key first step to achieving this objective is building community capacity, defined as local stakeholders’ skills, knowledge, and resources that may be leveraged for change. Interestingly, despite this conceptual importance, few researchers have focused on capacity building in the sport context. This has limited the theoretical advancement of community capacity theory as it relates to CSOs and community development. Using a qualitative case study approach, the authors analyze the outcomes and challenges of implementing community capacity building strategies in an American CSO, and draw on the empirical data to contribute to this theoretical conversation. Interviews, participant observation, and document analysis were used to generate data, and deductive techniques were used for thematic analysis. The results highlight the outcomes of the capacity building strategies and challenges associated with implementation. In addition, the conclusion focuses on theoretical contributions to community capacity theory, namely the role of sport in facilitating inter-community relations across social groups and the link with process models of organizational capacity.  相似文献   

The effect of marathon running on carnitine metabolism and on some aspects of muscle mitochondrial activities and antioxidant mechanisms     

M. B. Cooper  D. A. Jones  R. H. T. Edwards  C. Corbucci  G. Montanari  C. Trevisani 《Journal of sports sciences》2013,31(2):79-87

Carnitine is an essential co‐factor in the catabolism of fats as an energy source. The primary purpose of this study was to investigate the effect of running a marathon on the metabolism of carnitine by endurance‐trained athletes, and to evaluate the effect of carnitine administration on the performance of such exercise. The effects of marathon running on mitochondrial enzymes and cellular anti‐oxidants were also examined to assess whether the expression of these activities is altered by exercise. Subjects were 10 experienced male marathon runners aged between 19 and 25 years. Running a marathon caused a fall in the plasma content of unesterified carnitine (37%) and an increase in the level of acetylcarnitine present (288%). Loading of the athletes with L‐carnitine for 10 days before running a marathon abolished the exercise‐induced fall in plasma‐free carnitine (P<0.05) whilst amplifying the production of acetylcarnitine (P<0.05). Carnitine loading of the athletes studied made no detectable improvement in performance of the marathon (P > 0.05). Cytochrome oxidase, succinate cytochrome C reductase and Superoxide dismutase activities present in skeletal muscle were unaltered by marathon running. However, such exercise caused a large increase in the tissue content of oxidized glutathione (189%) at the expense of reduced glutathione (–18%).  相似文献
