样例的概化水平对原理通达和运用影响的实验研究

Effect of Generalization of Worked-out Example on Access and Use of Principle

用排列和组合原理为材料,探讨了编码样例解题步骤的子目标标签的概化水平对原理通达和运用的影响。实验1探讨不同概化水平的子目标标签编码样例解题步骤的情况下学习者原理通达的正确程度;实验2探讨不同概化水平的子目标标签编码样例解题步骤的条件下学习者原理运用的正确程度。结果表明:样例的概化水平影响原理学习过程中对原理的通达和运用;学习不同概括水平的样例,学习者获得图式的概括性也不同。

Using the probability principle problems as the materials, two experiments had been done to examine the effect of generalization of worked-out examples on the access and use of principle. Exp.1 probed into the effect of different generalization of subgoal labels on the principle access. Exp.2 probed into the effect of different generalization of subgoal labels on the principle use. The findings showed that it was the generalization of subgoal labels had some important effect on principle access and use. It was the different generalization of worked-out examples that make learner acquired different generalizational schema.
