图形推理任务中儿童策略获得的微观发展过程

运用微观发生学设计,对30名6岁儿童在矩阵填充任务中的策略获得过程进行了研究。结果发现:从策略获得的来源看,实验处理(教育干预)是图形推理策略获得的重要来源;从策略获得的个体差异看,儿童遵循的是学习领会或半学习领会的策略获得发展方式;从策略获得的路径看,快速组儿童在达到策略获得标准后正确率不高,而标准组和延迟组则能保持较高的正确率;从策略获得的速率看,在实验前3个阶段正确率有快速的变化,而到后期则保持正确率稳定不变。

A microgenetic study:Children's Strategy Discovery in Figure Reasoning Task

We use the microgenetic design to examine 30 6-age-old children's acquisition of matrix completion proficiency. The results are as follows: from the source of change, experimental manipulation is a important source of strategy discovery in figure reasoning task; from the variability of change, children are followed learner model of strategy discovery; from the path of change, the main error are orientation err and size err in all three groups. In norm group and latter group, there are also other errs displayed. When the children in quick group arrive the criterion of strategy discovery, their accuracy would likely come down; but in other two groups, the can maintain high accuracy; from the rate of change, children in the first three sessions display rapid changes in accuracy, however, their accuracy will maintain in high level in other sessions.
