Objective: Through the?establishing?of?online item bank?of medical physics

teachers and students can make use of the Internet to realize the interaction in or after class

so the students' ability of independent learning and the quality of teaching can be improving. Methods: Based on the teaching program

the type

quantity and difficulty of the test questions were determined through discussion and research among teachers in the teaching and research office

and the online item bank of medical physics was constructed with the help of the Internet platform to realize self-testing and teacher-student interaction. Results: A teaching evaluation system was established through the construction and practical application of this online item bank

the interaction between teachers and students was strengthened

and students' learning interest was mobilized. Self-examination and teacher-student interaction cultivate students' ability of independent learning and creative problem solving. The teaching feedback enables teachers to master students' learning situation and teaching quality. Conclusion: The?establishing?and?application?of?Internet + digital online item bank?of?medical physics can greatly promote the teaching effect.
