The purpose of this study was to determine whether patterns of strategy use in second, third and fourth grade children’s arithmetic
supported Steffe’s model of numerical development. In addition to student-generated strategies, we looked at commonly taught
algorithms not considered in Steffe’s model to determine whether these algorithms reflected underlying schemes. 206 children
were assessed on their strategy use while solving arithmetic problems in the second grade, the third grade and again in the
fourth grade. Factor analyses indicated some support for Steffe’s model, but there were exceptions. Not all children progressed
in their number knowledge and strategies as a function of schooling and schooling appeared to affect the types of strategies
children use independent of underlying schemes. 相似文献

Cognitive Development in Gifted Children: Toward a More Precise Understanding of Emerging Differences in Intelligence 总被引:3,自引:0,他引:3
To truly understand gifted performance, it is necessary to merge research on giftedness with current thinking in cognitive development and intelligence. This article presents traditional research on gifted children's cognitive development then considers how the application of newer models and theories from the field of cognitive development can be combined with research on giftedness to change the way people think about gifted performance. First four factors that have often been associated with giftedness are discussed from the perspectives of cognitive developmental psychology and gifted education. Next, emphasis is placed on investigating the strategic development of gifted children. Specifically, R. S. Siegler's (Emerging Minds: The Process of Change in Children's
Thinking, Oxford University Press, New York, 1996) model of strategy development is addressed in terms of what it may contribute to understanding gifted cognition. Finally, future lines of research using models from cognitive development and complex systems models of development are recommended. 相似文献

This article explores the unique positioning of leadership theory and literature as a unifying and informing discipline for the preparation of performance technologists. Although the role of leadership could be emphasized in any of the settings in which performance technologists become skilled, university departments of educational leadership seem especially suited for programs with this emphasis. A sample course activity is shared and linked to the building of leadership skills. The purpose of this article is to describe the importance of leadership as an informing and unifying discipline for the preparation of performance technologists and to explore the impact of this orientation on performance technologist preparation. 相似文献
