叠波模型理论由信息加工理论的代表人物——西格勒在关于儿童策略发展的研究中提出。它强调儿童个体间、个体内思维存在“变异性”。叠波理论通常从五个维度来分析儿童问题解决策略的变化规律,包括:变化的来源、变化的路径、变化的速率等。本文对于幼儿在“制作小汽车”中出现的策略“倒退现象”将从儿童问题解决中策略的变化路径这个角度来进行分析。 The theory of overlapped waves is proposed by Sigler in his research on the development of children’s strategy. It emphasizes that there are “variability ” in children’s individual thinking. Overlapping wave theory usually analyzes the changing law of children’s problem solving strategies from five dimensions, including the source of change, the path of change, the rate of change and so on. In this paper, the strategy of “retrogression” that children emerge in “making cars” will be analyzed from the perspective of the changing path of children’s problem-solving strategies.
