摘要通过在线医学物理学题库建设，利用互联网实现课上、课下检测，加强师生互动，实时掌握学生学习动态，及时调节教学，提高教学质量。根据教学大纲，通过讨论研究确定试题类型、数量及难易程度，借助互联网平台构建数字化在线医学物理学题库，实现自助检测和师生互动。结果表明，通过在线题库建设及应用，调动了学生学习主动性、提高了师生互动有效性，获得了教学形成评价实证材料；利用后台数据，实现教学反馈，及时调整教学计划，提高了教学质量。

abstractsObjective:Through constructing an online question database of medical physics, teachers and students can make use of the Internet to realize interaction in or after class, so students' ability of independent learning and the quality of teaching can be improved.Methods:Based on teaching outlines, the type, quantity and difficulty of the test questions were discussed and determined by teachers in the teaching and research office, and the online question database of medical physics was constructed with the help of Internet platform to realize self-testing and teacher-student interaction.Results:Through the construction and application of online question database, students' learning initiative was mobilized, the effectiveness of teacher-student interaction was improved, and empirical materials for teaching formation evaluation were obtained. Self-examination and teacher-student interaction help improve students independent learning and problem solving ability. And data generated on the platform enable teachers to know students' learning situation and their teaching quality.Conclusion:The construction and application of Internet + digital online question database of medical physics can greatly promote the teaching effect.
