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核心知识关系图的使用效果。本研究以46名初中生为被试，在课时延长至6小时的课时内，利用关系图对物质的物理状态变化主题进行了研究，并在课前(前测)和后测(后测)两个阶段对学生的理解能力进行了评价。结果表明：1.使用关系图学习的初中生意识到物质的状态变化主题与物质的粒子模型有关。后测显示，超过60%的初中生尝试使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.
