Polymer physics is an important professional basic course of students majoring in polymer materials and engineering. "Crystallization" is an important concept in aggregation structure of polymer. Large molecular weight and long chain molecular structure make the crystallization process of polymers more complicated compared with that of small molecules. In the teaching process of polymer physics

we introduce students the relationship between crystallization and ordered

chain flexibility

glass transition temperature

and put some concepts in series

which are related to crystallization (such as crystallinity

crystallization temperature

melting point and crystallization rate). The aim is to establish scientific cognitive system about polymer crystalline structure for students in their preliminary stage. Practices show that the majority of students have a good understanding and mastery of these teaching contents through this way.
