朴素表征影响物理问题解决的实验研究

Experiments on effects of naive representation onto the physics problem solving

设计了两个实验以探究其朴素表征对物理问题解决的影响．以初二学生为被试的实验Ⅰ，通过１８个动力学题目的测试，对影响建构科学理论表征的朴素概念（即物理前概念）及其渊源进行了探讨．而以初一、初二、高一、高二及大学二年级的部分学生为被试的实验Ⅱ，通过两个运动学问题的测试，探究了学校物理教学对朴素表征的影响．结果表明，直觉经验和物理教学均对朴素表征有影响．后者的影响将随学习的深入而逐渐消除，前者的影响则不易消除．

The two experiments were designed for discussing the effects of the naive representation onto the physics problem solving.The results show that naive representation has strong influence to the physics problem solving and is affected by preconceptions of physics which not only come from the intuitive experience but also from physics education.But the later can be eliminated gradually by the further study.
