"Polymer processing principles" is a core curriculum for the students majored in polymer materials processing. This course owns theoretical and practical characteristics

rich content and widely coverage. It is difficult for students to fully comprehend the curricular knowledge. The mode of traditional homework is completing the exercises just in the textbook with the interrogation reply way. By virtue of this simple way

it could hardly obtain a good teaching effect. Based on the need of teaching activity and the major feature on polymer processing

a test bank of polymer processing principles was constructed from the view of test content

types and knowledge levels. The test bank consists of homework

social practice subjects

periodical tests and experimental questions. An exercising mode with the feedback property between teacher and students combining the application of test bank was gradually formed. Compared with the learning effect of students

it is found that introducing the test bank was prone to clarify the knowledge mastery degree of students objectively

which was conducive for the teacher to adjust teaching contents. Moreover

the test bank could assist students to understand the key points of knowledge

apply the knowledge to solve practical problems and stimulate the research interest.
