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

A family developmental framework was applied to data from families of children with intellectual disabilities to understand the role of parenting in the path from early adversity to problem behaviors in mid-childhood. Data from 9 months to 11 years tested the Family Stress Model in families of 555 children. Adversarial parenting between 3 and 5 years mediated the path from early adversity (family poverty and maternal psychological distress at nine months) to problem behaviors at 7 and 11 years. Positive parent–child relationship only mediated the path to conduct problems. Multiple mediation was not present. Early adversity impacts both positive parent–child relationship and adversarial parenting between three and five, but the latter is crucial for problem behaviors in mid-childhood. 相似文献

Our research is concerned with the visual representations found in textbooks used for the teaching of the Internet in Greek
secondary schools. Visualization, as both the product and the process of creation, interpretation and reflection upon pictures
and images, is considered here to be very important, as it is the only way students gain insight into the nature and function
of the Internet, its size, complexity and invisibility. Initially, we attempted to analyze and reflect upon school textbooks’
visual interpretations of the Internet. A scheme of categories of visual representations has been identified and reveals the
characteristics of the textbooks’ representations as well as their limitations. Sketch-comics and computer snap-shots are
the more popular types of Vrep, although a considerable number of them cannot be characterized as accurate and few of them
have an explanatory or complementary function in terms of the content presented in the text. We have also explored the impact
on students’ readings of two visual representations in one of the textbooks, used without any caption or textual information.
The phenomenological aspects of the VRep seem to attract students’ attention and create obstacles in conceptualizing the main
idea conveyed in both representations, but when the field of ICT is implied and not clearly portrayed in the VRep, students
face serious problems in recognizing the phenomenon. It seems that it is difficult for an image on its own to paint a thousand
words. 相似文献

The role of digital technology in assessment has received a great deal of attention in recent years. Naturally, technology offers many practical benefits, such as increased efficiency with regard to the design, implementation and scoring of existing assessments. More importantly, it also has the potential to have profound, transformative effects on the field of assessment by facilitating the integration of formative activities with accountability requirements and broadening the range of abilities and the scope of constructs that can be assessed. This article provides an overview of the current state-of-the-art in digital technology-based assessment, with particular reference to advances in the automated scoring of constructed responses, the assessment of complex 21st century skills in large-scale assessments and innovations involving high fidelity virtual reality simulations. Key challenges with respect to each are highlighted before the extent to which digital technology is truly transforming assessment is considered. 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
