【摘要】 本研究设计了一个模拟的初级运动系统,让14名五至十岁的被试解决该系统中的车速比较问题,通过收集和分析被试解题的原始材料,结果发现:(1)被试解题中存在两类不同性质的错误:知识性错误和策略性错误;(2)在这些被试的解题行为中,存在着四种不同的策略,这些不同的解题策略,在一定程度上反映了被试的认知发展水平。根据这些结果,作者对问题解决中的知识和策略的性质及其关系,作了进一步的讨论。更多还原

【Abstract】 A simulated primary movement system was designed in this experiment. 14children aged from 5 to 10 were asked to compare the bus speed in thesystem. Analysis of the protocol of the subjects’ performance showed: (1)there were two kinds of errors in their problem solving error in knowle-dge and errors in strategy; (2) In their problem solving, it was found thatthey used four different strategies, which reflected to a certain extentchildren’s cognitive development level. On the basis of these results, theauthors discussed the role of knowledge and strategy in problem solvingand the relationship between them.更多还原
