模型素材差异对初中生“分子和原子”概念认知水平影响的观测工具设计

Tools Design for Evaluation on Influence of Model Material Differences on Junior High School Students’ Cognitive Level of “Molecule and Atom”

模型是为了理解事物而对事物做出的一种抽象,不同模型对学生关于同一概念的认知理解会产生不同的影响。以初三化学"分子和原子"章节为载体,设计了可以观测模型素材差异对初中生"分子和原子"概念认知水平影响的3份工具。

Models are abstractions of things to understand objects, and different models have different effects on students' cognitive understanding of the same concept. Based on the "Molecule and Atom" chapter of junior high school chemistry, this article designs three tools that can be used to evaluate the influence of different model material on junior high school students' cognitive level of the concept of "molecule and atom".
