Effects of Using the Relational Chart of Core Knowledge from Elementary to Junior High School Science

本研究的目的是探讨使用核心知识关系图的效果。46名初中生在延长至6小时的课程中使用关系图学习了关于物质物理状态变化的主题，并在课前（测试前）和课后（测试后）对他们的理解进行了评估。我们得到了以下两个结果：1。使用关系图学习的初中生意识到状态变化的话题与物质的粒子模型是有联系的。后测显示，60%以上的初中生尝试用物质的粒子模型来解释高级任务。

The purpose of this study was to investigate the effects of using the relational chart of core knowledge. Forty-six junior high school students studied the topic about changes in physical state of matter using the relational chart in lessons that were extended to six hours, and their understanding was evaluated both before (pre-test) and after (post-test) the lessons.We obtained the following two results : 1. Junior high school students who studied using the relational chart realized that the topic of changes of state was connected with the particle model of matter.2. The post-test showed that more than 60% of the junior high school students tried to explain the advanced task by using the particle model of matter.
