Abstract 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".
