A multivariate analysis of exceptional states in 384 children aged 6 years is presented. Predictors were six items of information in the domain of child development, four items were in the domain of social factors, and three items were maternal traits. Criteria were six of nine exceptional states on which there were enough cases for multivariate analysis. The AID-4 interaction regression method was the technique of analysis applied to data gathered by prospective longitudinal study. No consistent sets of predictors were found for the criteria. However, Coddington's Life Changes scores were frequently observed as prime sources of variance. Social class scores were also important influences on criteria of exceptionality. 相似文献

Past research on teachers' causal attributions has shown there to be little relation between perceptions of responsibility for positive versus negative student learning outcomes. In this study, Weiner's model for causal attributions was employed to explore these perceived attributional differences. Data were gathered from 184 teachers from two metropolitan school districts. Statistically significant differences between attributions for positive versus negative outcomes were identified along the dimensions of both internality/externality and stability of cause. Relations to overall efficacy, teaching experience, grade level taught, and teacher gender were also explored; however, only grade level differences were found to be statistically significant. 相似文献

Bias in content validity on the Boehm Test of Basic Concepts for White and Mexican-American children
Wayne C. Piersel Barbara Sterrett Plake Cecil R. Reynolds Richard Harding 《Contemporary educational psychology》1982,7(2):181-189
Item bias on Forms A and B of the Boehm Test of Basic Concepts was examined for a sample of White and Mexican-American kindergarten children. The method employed to detect biased items, as defined by an items-by-group interaction, was a two-way analysis of variance with followup being conducted with a Bonferroni-type procedure. Bias-in-item difficulty occurred for both groups, which does not conform to the current popular press view that bias is against ethnic minorities and not against the White majority. The finding that on some items the Mexican-American group out-performed the White group indicates the need to examine carefully the question of bias and to reconsider popular conceptualizations of the many issues of bias in educational and psychological testing. 相似文献

This paper considers the scope for beneficial scientific co-operation and technology transfer among ASEAN countries, Australia and New Zealand in the light of differences in the development status of these countries, their proximity to one another, their resource endowments and other factors. Australian official science and technology aid in the ASEAN region (which of necessity involves some co-operation between the donor and aid recipients) is considered as well as recent initiatives of the Australian Department of Science to promote fully co-operative (‘non-aided’) R&;D in the region. Two examples of regional co-operation in R &; D are considered briefly, namely the development of a malaria vaccine and giant clam farming. 相似文献

The Australian wine industry's popular image as a leader in R&D can indeed be substantiated. Its oenological and viticultural innovation and technical expertise have set new international benchmarks. The coordination of this R&D has ensured that the industry remains at the leading edge. However, the findings of this paper also substantiate concerns that this R&D is concentrated in what appears to be a South Australian R&D 'epicentre'. Regions and wine operators not connected to this epicentre can be disadvantaged. This paper examines the diffusion of R&D to regional operators and suggests mechanisms for improvement of the current structure. 相似文献

This paper provides a review of Israel's science and technology policy and traces the growth and development of technology intensive industry in that country. Such policy has generally been neutral with regard to industry, technological field or class of product; concentrates on industrial R &; D directly performed in industrial firms; and is an integral part of overall national industrial policy — being centred in the Ministry of Industry and Commerce. Drawing upon case studies and other statistical evidence, the paper argues that such policy has been partly responsible for Israel's success in building up an indigenous, export-oriented, high technology sector. 相似文献
