中外高中化学教材图表系统的比较研究——以“化学键”内容为例

Comparative Study of Graphic System Between Chinese and Foreign Chemistry Textbooks:Taking Chemical Bond as Example

通过定量的方法，对10个国家高中化学教材“化学键”内容图表系统从图表数量、图表密度、图表类型3个维度进行比较，发现各国高中化学教材图表类型都较为丰富，其中模型类图表的使用最多，且图表主要分布在共价键这一核心概念中。中国教材图表数量和图表密度在10国排名居中，图表类型略有欠缺。

A quantitative comparison was made on the amount, the density and the categories of graphic system in chemical bond between Chinese and foreign chemistry textbooks. This study found that the categories of graphs were relatively abundant in every country chemistry textbooks and the use of the model class graphs were the most. In addition, graphs were mainly distributed in the core concepts of covalent bond. The amount and the density of Chinese chemistry text books were in the center of ten ranking, and the categories of the graphs were slightly deficient.
