信息表征形式对初中生解决MHD问题的影响

The Effects of Information Representation on Junior High School Students’ Solution of the MHD

研究以经典MHD问题作为实验任务,通过两个实验分别探讨了心理模型表征与条件关系表征、以及文字表述辅以图形的表征对初中生解决MHD问题的影响。结果发现:(1)心理模型表征与明确选手行为与主持人行为之间的条件关系表征都没有有效促进被试解决MHD问题;(2)文字表述辅以图形的表征显著提高了被试MHD问题的推理成绩。这似乎说明对初中生而言,适当的信息表征形式有助于促进其解决MHD问题。

This paper, composed of two experiments, examined the influence of information representation on the resolving of MHD;the subjects were junior high school students. The result indicated that ： （ 1 ） Neither mental model representation nor clear representation of the logical relation between the contestant and the host took effect in MHD reasoning. （2） Logical relation representation assisted figure was the key of resolving MHD. Findings indicated that the proper information representation played an important role in junior high school students＇ MHD reasoning.
