This study investigated patterns of Bannatyne's recategorized WISC-R scores of 146 predominantly Tlingit Indian children who were referred for psychoeducational testing. The students were divided into two groups, ages 6 through 10 and 11 through 16, in order to investigate patterns that occurred at each level and to investigate the proportions that exhibited a typically “Indian” pattern: Spatial > Sequential > Conceptual and Acquired Knowledge. As a group, the older children displayed an Indian pattern, but the younger children displayed a different one: Spatial > Conceptual and Sequential > Acquired Knowledge. Both groups, however, displayed a significantly greater proportion of children with an Indian pattern than would be expected by chance. A considerable number of individuals from both groups attained significant differences among scores in the Indian direction. 相似文献

A number of studies have shown, counter-intuitively, that skilled adult readers find it difficult to correctly relate phonemes to graphemes in written words. In most adults this is of little consequence. However, teachers are required to show children how to relate phonemes to graphemes when teaching reading. This study investigated whether a brief period of instruction would improve the ability of adults in this task. Results showed a general level of improvement relative to controls. Exposure alone to the task had no effect. Improvement for the instructed group was not very large and there was difficulty relating phonemes to graphemes which had more than one letter. It may be that trainee teachers need instruction to improve knowledge of grapheme phoneme correspondence so that they can pass such knowledge onto young readers. 相似文献

Research into sighted children’s reading shows that letter recognition skill predicts phonological awareness skill. Congenitally–blind children do not receive exposure to environmental print and do not generally learn to recognise written letters of the alphabet prior to schooling in Braille. A cross–sectional analysis revealed that blind children with no knowledge of written letters or written words showed no ability at measures of phonological awareness. Blind children with knowledge of written letters and no written words showed much increased phonological awareness scores and blind children with knowledge of written letters and written words scored higher still on phonological awareness measures. It was concluded that letter learning is a major contributor to the development of phonological awareness in blind children. It suggests key similarities in the underlying processes of reading development across two different populations using different modalities to learn to read. 相似文献

Abstract: The current generation of students coming into food science and engineering programs is very visually oriented from their early experiences. To increase their interest in learning, new and visually appealing teaching materials need to be developed. Two diverse groups of students may be identified based on their math skills. Food science students tend to find it difficult to use mathematics as a problem‐solving tool for food engineering problems. Food engineering students, on the other hand, should be challenged to use emerging mathematical tools to develop their problem‐solving skills. Therefore, the approach of this project involved the development of a curriculum to train undergraduate food engineers in the effective use of computational fluid dynamics (CFD) software to solve food engineering problems by engaging them in the creation of food engineering teaching tools. These CFD outputs were then used as innovative teaching tools for the food science students. In this paper, this concept will be illustrated by unsteady‐state heat transfer and fluid flow problems. To evaluate the efficiency of the teaching materials developed, a student focus group was asked to answer the same quiz following a conventional and CFD output aided teaching session. The assessment result showed an improved understanding of the subject after the CFD teaching session. These visual aids were excellent tools to illustrate the validity of the formulas presented in class. In addition, the new visual materials enabled a better understanding of the relationships among different process parameters. In general, this helped the food science students better appreciate the food engineering concepts that govern food processing operations. 相似文献
