The purpose of this study was to assess Greek primary (1st to 6th grade) school children’s dietary habits and the factors
influencing them. Our results show that children know the value of different foods. The socio-economic status of father has
no effect on the attitude of children towards choosing their diet, however, mothers’ educational status appears to have an
effect on their children’s behaviour. Place of residence (urban or semi-rural areas) and gender does not influence their knowledge
about different diets. It was, finally, shown that as children grow older they tend to eat less healthy foods. 相似文献

The purpose of this study was to assess Greek primary (1st to 6th grade) school children's understanding of sun exposure during summer vacation. Our results show that children know the damaging effects of long time exposure and the precautions that should be taken during sun bathing (sun glasses, hat, umbrella, sunscreen, etc). Nevertheless, they do not seem to avoid being exposed between 12.00 A.M. and 15.00 P.M., which is the most dangerous time. The socioeconomic status of father has no effect on the attitude of children towards taking protection measures when exposed to the sun, however, the educational status of the mother appears to influence children's reported knowledge and behaviour. Place of residence (urban or rural areas) and gender does not influence their knowledge on the sun's damaging effects and the precautions they should take. Finally, as children grow older they seem to gradually reduce the protective measures they take. 相似文献

Given a graph, how to find a small group of ‘gateways’, that is a small subset of nodes that are crucial in connecting the source to the target? For instance, given a social network, who is the best person to introduce you to, say, Chris Ferguson, the poker champion? Or, given a network of people and skills, who is the best person to help you learn about, say, wavelets? We formally formulate this problem in two scenarios: Pair-Gateway and Group-Gateway. For each scenario, we show that it is sub-modular and thus it can be solved near-optimally. We further give fast, scalable algorithms to find such gateways. Extensive experimental evaluations on real data sets demonstrate the effectiveness and efficiency of the proposed methods. 相似文献

This paper describes an attempt to infuse an environmental dimension into a science course through which prospective primary teachers are trained. The innovation concerns teaching science concepts not in the context of the discipline, but within a context of everyday life, and as such the focus chosen was drinking water. In formulating the course, learners’ ideas about aspects of the issue were taken into account. The evaluation was based on a post‐course questionnaire. The main conclusions to be drawn from this evaluation is that the science knowledge learned through this approach helped students gain a better understanding of a variety of aspects which concern that issue. The majority of students appreciated such an integrated approach and thought the approach taken was more promising than the stereotypical one that they had been accustomed to up to that point. 相似文献

Prospective Primary Teachers' Understanding of Climate Change, Greenhouse Effect, and Ozone Layer Depletion 总被引：1，自引：3，他引：1

Climate change is one of the most serious global environmental problems and for that reason there has been lately a great interest in educating pupils, the future citizens, about it. Previous research has shown that pupils of all ages and teachers hold many misconceptions and misunderstandings concerning this issue. This paper reports on research concerning student teachers' perceptions about aspects of climate change as well as about greenhouse effect and ozone layer depletion. The aim of this research is to take findings into account for teaching student teachers about these issues. An open-ended questionnaire was used in order to gain a more comprehensive understanding of their thought. From their answers it appeared that these students believe that climate change is under way and base their beliefs on their own experience. They are unaware of the proper actions to be taken for slowing down the climate change, they also hold the misconception that ozone depletion, acid rain, and pollution in general are conducive to climate change. They confuse greenhouse effect with ozone depletion as far as the mechanisms through which they occur is concerned and the causal compounds. By taking into account these research findings the possible implications for teaching are discussed and some suggestions for more effective teaching are made. 相似文献

This paper deals with an attempt to organize a university research‐based course the aim of which is to promote in‐service primary teachers’ professional development in environmental education. The decision to engage them in participatory action research was made after a careful investigation of the factors that seem to discourage them from becoming involved in environmental education. From the results that have come out of the evaluation, the process that was followed appears to be a promising way for empowering teachers to overcome existing obstacles, so as to promote environmental education. The various problems that crop up in the running of such a course are identified and some suggestions for their resolution are offered. 相似文献
