The internalization of knowledge is a process in which an individual digests and absorbs the received knowledge and convert it to discipline thought. The students' knowledge internalization and application ability can be trained by sorting out the main line of research

finding out the basic research methods and the interconnection of knowledge modules

building interchange knowledge system. Taking the teaching of "Polymerization Dynamics" as an example

the specific teaching design of the above ideas is introduced: The equal reactivity hypothesis as research principal line runs through the knowledge system of polymerization kinetics. Differential and integral are used as the basic methods of related calculation for chain polymerization and stepwise polymerization

respectively. Dynamic chain length is regarded as the bridge between the degree of polymerization and the rate of polymerization

and the reactivity ratio as the bridge of the composition

segment sequence of copolymers between copolymerization rate.
