Influence of Graphic Analysis and Text Analysis Examples on Learning Transfer Effect of Chemical Experiment Scheme Design Questions

通过实验研究探讨样例和无样例学习对化学实验方案设计题的学习效果,以及图示解析和文字解析样例对化学实验方案设计题学习迁移效果的影响。结果发现:(1)样例学习组的近、远迁移成绩显著高于无样例学习组的成绩。(2)在近迁移成绩上,图示解析组显著高于文字解析组和没有解析组;在远迁移题成绩上,图示解析组成绩显著高于没有解析组。研究表明:样例学习是解决化学实验方案设计类等复杂化学问题的一种有效学习方式;图示解析样例比文字解析样例对化学实验方案设计题学习迁移的效果更好。

Through experimental research,this paper discusses the learning effect of sample learning and non-sample learning on chemical experiment scheme design questions,and the influence of graphic analysis examples and text analysis examples on the learning transfer effect of chemical experiment scheme design questions.The results show that:(1)the near and far transfer scores of the sample learning group are significantly higher than those of the non-sample learning group.(2)In the near transfer performance,the graphic analysis group is significantly higher than the text analysis group and the no analysis group;In terms of the scores of far migration questions,the scores of the graphic analysis group are significantly higher than those of the non-analysis group.Research shows that sample learning is an effective learning method to solve complex chemical problems such as chemical experiment scheme design.The example of diagram analysis is better than the example of text analysis in the learning transfer effect of chemical experiment scheme design questions.
