The responses of 22 physically handicapped children to selected items of the Piers‐Harris Self Concept Scale for Children were compared with their mothers’ responses to equivalent items of the Personality Inventory for Children. The direction of the responses, whether children were more or less positive in self‐evaluation than mothers perceived them to. be, was analyzed with respect to sex of child, type of school attended, and diagnosis of handicap (cerebral palsy or spina bifida). Only diagnosis of handicap was significantly related to the tendency for children to be either less or more positive in response to the items than their mothers, with cerebral palsy children more positive and spina bifida children consistently less positive in direction. Possible explanations are considered, with particular reference to the children's views regarding peer relationships. 相似文献

Jigsaw puzzles are ubiquitous developmental toys in Western societies, used here to examine the development of metarepresentation. For jigsaw puzzles this entails understanding that individual pieces, when assembled, produce a picture. In Experiment 1, 3- to 5-year-olds (N = 117) completed jigsaw puzzles that were normal, had no picture, or comprised noninterlocking rectangular pieces. Pictorial puzzle completion was associated with mental and graphical metarepresentational task performance. Guide pictures of completed pictorial puzzles were not useful. In Experiment 2, 3- to 4-year-olds (N = 52) completed a simplified task, to choose the correct final piece. Guide-use associated with age and specifically graphical metarepresentation performance. We conclude that the pragmatically natural measure of jigsaw puzzle completion ability demonstrates general and pictorial metarepresentational development at 4 years. 相似文献

The structure and evolution of industrial clusters: Transactions, technology and knowledge spillovers 总被引:2,自引:0,他引:2
In this paper, we investigate the relationship between location patterns, innovation processes and industrial clusters. In order to do this we extend a transactions costs-based classification into a knowledge-based taxonomy of clusters, along the lines suggested by a critical revision of the main assumptions underlying most of the existing literature on spatial clusters. Our arguments show that the transactions costs approach and the innovation and technological regimes framework are broadly consistent, and that real insights into the microfoundations, nature, and evolution of clusters can be provided by these classification systems. 相似文献

This article is about the quantitative research practices and methodologies that are used in distance education (DE). It begins with an analysis and assessment of a segment of the DE research literature, DE/classroom comparison studies, based on a recently completed meta-analysis of that literature from 1985 to 2002. Overall, the 232 studies reviewed were judged to be of poor methodological quality and severely lacking in critical information about research practices. Studies of synchronous and asynchronous DE are discussed separately and recommendations are made for improving designs and measures within these patterns. Suggestions for future quantitative research areas are provided. In discussing these findings, we recognize that high-quality research is being conducted in the field and that qualitative forms of research contribute greatly to the mosaic of evidence that is the base of available knowledge about DE. Finally, three organizations, the What Works Clearinghouse (USA), EPPI-Centre (UK), and the Campbell Collaboration (international), all devoted to improving the quality of research and research synthesis in education, are described briefly; suggestions are made as to how their philosophies and approaches for judging the worthiness of research evidence can be used to improve DE research. 相似文献

Toys are not just for playing. Toys are the tools of play that help children develop their social awareness, imagination, visual motor capabilities and thinking processes. Play is a very serious activity for children worldwide and often represents a primary and valuable means of learning. Since many toys are important learning instruments, children should have easy access to appropriate toys in order to explore and choose those which interest them. In addition, parents need a place where they can consult with someone about what toys are appropriate for their child's development. Toy libraries provide this service. 相似文献
