As the development of polymer technology

polymer chemistry has become the compulsory course of chemistry

chemical engineering and material majors. In addition to these majors

many science majors also selected polymer chemistry as one of elective courses. It is very difficult to learn for many students due to the complexity of concept. During the teaching of polymer chemistry course

authors used many new teaching models such as "analogy teaching"

"object teaching"

"flipped teaching" and "formula teaching" to improve the knowledge understandings for students. The applications of these teaching also help student enhance the learning capability.
