Polymer Physics

is a professional basic course for students majored in polymer materials. It plays an important role in enhancing students' thinking ability

helping students understand professional knowledge and improve their ability for practical applications. In the Internet era

following the OBE teaching concept of "student-oriented and output oriented"

it is necessary to take full advantage of the online teaching to closely combine online and offline teaching to construct the online and offline mixed teaching mode of

Polymer Physics

based on MOOC. Taking "molecular movement of polymer" section as an example

the online and offline mixed teaching mode composed of three stages of "selfstudy before class-offline Teaching (face-to-face teaching)-review and consolidation after class" are elaborated in detail. Learning effectiveness is evaluated by means of teaching goal achievement and student questionnaire survey

and the results show that the mixed teaching mode could improve students' learning interest and motivation

and the teaching effect is excellent.
