小学生人工概念形成中认知策略发展的研究

The subjects under two different educational conditions were presented with a multidimensional discrimination task. Their responses were analyzed in terms of nine strategy components, scores on which were analyzed by means of cluster analysis. In combination with the cluster analysis, the qualitative analysis was used to analyze the development of primary school pupils' strategies of artificial concept formation. The results indicate that: (1) Different strategies used by pupils have different influence on their artificial concept formation; (2) The pupils of grade 2 tend to use stimulus-preference and stimulus-describing strategies, while the pupils of grade 4、6 tend to use dimension-checking and focusing strategies to form artificial concepts; (3) Under the different educational conditions, there is a significant difference between the pupils of grade 2 and grade 4, while no significant difference between the pupils of grade 6; and (4) The strategy components change in a complicated manner in the development of the primary school pupils' strategy. With the development of cognitive strategies, some components' scores increase while some increase at first, and then decrease rapidly.
