A LONGITUDINAL STUDY OF THE DEVELOPMENT OF MATHEMATICS STRATEGIES AND UNDERLYING COUNTING SCHEMES     

Barry Biddlecomb  Martha Carr 《International Journal of Science and Mathematics Education》2011,9(1):1-24

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   

Online collaborative documents for research and coursework     

Karen L. Murphy  Lauren Cifuentes  Yu-Chih Doris Shih 《TechTrends》2004,48(3):40-46

Conclusion Garrison’s (2000) review of distance education theories describes the current need for ”sustained real two-way communication ... that refiect(s) a collaborative approach to distance education” (p. 13). One way to apply such theories to research and coursework is to use collaborative documents to promote transactions culminating in deliberation among the key players. Such deliberation can create ”a particular kind of democratic public culture among the deliberators: listening as well as talking, sharing resources, forging decisions together rather than only advocating positions taken earlier, and coming to disagreement” (Parker, Ninomiya, & Cogan, 1999, p. 129). Her research interests are collaborative learning in distance education, impact of culture on online learners, and design of online instruction for constructivist learning environments. Her primary research interests are in design considerations for collaborative online environments and in the powers of shared multimedia for enhancing personal growth, multicultural understanding, and global awareness. She investigates visual messages: how they can be shared and interpreted by learners, their impact, and how their impact can be researched. Her research interests are in computer and network-based foreign language and cultural learning.  相似文献   

A Framework for Research on Large-scale Reform   总被引：1，自引：0，他引：1  

Kenneth Leithwood  Doris Jantzi  Blair Mascall 《Journal of Educational Change》2002,3(1):7-33

Variation in the success of large-scale reform is afunction of many factors interacting at many ``levels'.Built on a selective review of the evidence aboutlarge-scale reform, this paper provides a framework forexplaining such variation, as well as assessing progressin that direction. Relevant factors influencing reformsuccess, according to the framework, include broad international social, economic and political trends bearing on education, characteristics of national educationalpolicies and strategies for their implementation, and localconditions conceptualized in terms of a model of workplaceproductivity; this model is defined by local practitioners' motivation, capacity, and the organizationalconditions in which they work. This framework has been usedto guide the external evaluation of the National Literacy andNumeracy Strategies.  相似文献   

Serial rapid naming skills in children with reading disabilities     

Lynn S. Snyder  Doris M. Downey 《Annals of dyslexia》1995,45(1):29-49

This study compared the performance of children with reading disability (RD) and normal reading achievement (NRA) on tasks of serial rapid naming, verbal fluency, letter-based word retrieval, and articulatory speed. The groups, composed of children at two discrete age levels, one younger and one older, were matched for age, gender, and neighborhood school. Analyses of the on-line measurement of the children’s serial rapid naming indicated that the children with RD had significantly larger reaction times and production durations than their NRA peers despite similar levels of accuracy. They also performed significantly worse on the categorical verbal fluency task, the letter-based word retrieval task, and the test of articulatory speed. The findings suggest that both access and post-access processes, such as oral-motor inefficiency that extends the duration of word production, may be implicated in the slower serial rapid naming that has typified many samples of children with RD. This work was supported in part by Basil O’Connor Research Grant 5-340 from the March of Dimes Birth Defects Foundation, a Scholarly and Creative Activity Award and sabbatical leave from California State University, Long Beach and grant #DCO 1904-01 from the National Institute on Deafness and Other Communication Disorders of the NIH to the first author.  相似文献   

Control of Practice and Level of Feedback in Computer-Based Instruction     

Pridemore Doris R.  Klein James D. 《Contemporary educational psychology》1995,20(4)

This study investigated the effect of type of control and level of feedback during computer-based instruction. Subjects completed a computer lesson about the microscope that presented either mandatory or optional practice questions. Practice was accompanied by either elaboration feedback, correct-answer feedback, or no feedback. Results indicated that level of feedback had a significant effect on achievement and attitudes. Implications for including feedback in computer-based instruction are discussed.  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  

Hillary Hettinger Steiner  Martha Carr 《Educational Psychology Review》2003,15(3):215-246

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
