样例的子目标编码对新问题解决中原理通达的作用

通过 3个实验 ,分别研究了样例的不同编码对消除由于表面概貌和表面对应变化对原理通达带来的消极影响的作用以及样例学习中原例概化的形成阶段。实验结果表明 :样例解题步骤的子目标编码有助于消除由于表面内容变化对原理通达带来的消极影响 ;子目标学习使学习者在样例学习阶段就形成了关于原理的概化。

Effects of Subgoal Encoding of Examples on the Access of Principle in New Problem Solving

Three experiments had been done to examine the effect of subgoal encoding of examples on the access of principle and generalization in new problem solving.The findings showed that it was the encoding subgoal of steps of worked example that overcame the surface content effects on the access of principle, which was caused by the modification of the superficial story lines and superficial roles correspondence between examples and problems.In encoding subgoal of steps of worked example,the participants could develop the generalization of the example during the learning,so that the modification of the superficial story lines and superficial roles correspondence between examples and problems had little effect on the access of principle.
