The purpose of this study was first to assess and then to improve the diet of Greek primary school children teaching them healthy dietary habits and instructing them to face critically advertisements and media projected dietary models using a program which included intervention on cognitive, emotional, and social level. The results show that our intervention was more effective on the cognitive level and in particular on children's ability to estimate the dietary value of different kinds of food. However, their food preferences were not affected significantly, suggesting that these are more resistant to change since they are already consolidated and, therefore, need longer intervention. 相似文献

This study addressed a puzzling discrepancy in existing research about when children achieve and manifest a mentalistic conception of the person. Narrative research suggests that children do not represent characters as mental agents until middle childhood, whereas social cognition research places this understanding at around 4 years. Using a theoretically informed typology, 617 stories were analyzed composed by 30 children participating in a storytelling and story-acting practice integrated into their preschool curriculum. Results indicated that children's representation of characters shifted from almost exclusively physical and external portrayals of "actors" at 3 to increasing inclusion of "agents" with rudimentary mental states at 4 and of "persons" with mental representational capacities by 5. The developmental trajectories of boys and girls differed somewhat. 相似文献

This paper explores the function of the visual syntax of images in Greek primary school textbooks. By using a model for the formal analysis of the visual material, which will allow us to disclose the mechanisms through which meanings are manifested, our aim is to investigate the discursive transition relating to the view of nature and the human-nature relationship between two series of natural science textbooks. The model is applied to a total of 635 pictures; 434 coming from the old series of textbooks introduced in the early 1980s and 201 from the new introduced in 2006. The results show that a) no differences in the codes of the visual representation of nature or human-nature relationship were recorded between the two series of textbooks, b) the environmental rhetoric mediated by the pictorial material of the textbooks appears closer to its lay counterpart than to scientific rhetoric, c) both series of textbooks favor a viewer-picture relation which diverges from the epistemological (subject/object) ideas of the romantic worldview and comes closer to the baroque one that depicts the world as non-linear and disconnected, while gives more freedom to the viewer to proceed to subjective interpretations. Thus, we assert that the baroque approach adopted by both series of textbooks does not aim at the initiation of students to the highly conventionalized ways of expression, and ultimately to the formalized and scientific rhetoric. On the contrary, within a constructionist context, the textbooks’ visual mode allows students to equally share power with a quite familiar world. 相似文献

The study reported here used a systematic interpretive analysis of young children's spontaneous narratives to investigate the development of their conceptions of the person. We argue that currently predominant approaches to this subject in social cognition research are insufficiently sociocultural and need to be broadened and reoriented (a) to capture the social (rather than purely mentalistic) dimension inherent in any conception of the person, (b) to examine how the development of children's conception of the person involves the selective appropriation of culturally elaborated models of personhood, and therefore (c) to recognize that children develop and employ different conceptions of the person, in ways that are socioculturally patterned. The study examined a body of 598 stories generated by 30 preschool children (5 girls and 5 boys in 3 age cohorts: 3s, 4s, and 5s) through a storytelling and story-acting practice that was a regular (but voluntary) part of their classroom activities for the entire school year. Analyses indicated that in their narratives the girls and boys constructed and elaborated two distinctive gender-related conceptions of the person: girls a socially embedded and interdependent person, who becomes increasingly individuated and self-consciously responsible; boys a separate and agonistic person, who increasingly becomes a stable, autonomous, and self-conscious mental agent. Typologies are presented to delineate and compare the developmental pathways of these two gender-related models of personhood. Some implications for early childhood education are also discussed. 相似文献
