摘要本研究围绕多元互动在线上教学中的应用问题，结合中南大学湘雅医院麻醉学专业麻醉设备学课程的实际教学案例，详细展示了麻醉设备学课前互动教学准备工作、线上课堂中的互动教学、课堂外互动教学的延展和互动教学的评估反馈机制整个实施流程。通过建立"主持人—嘉宾—观众"模式，实现线上直播效果最大化；通过以学生为主体的360度具象化讲解，打通线上教学中上线不上课、学生无思考等痛点、堵点，推进线上教学质量、效率双提升。在后续教学实践中，还需在教师人才素质提升、高效人才团队搭建，以及教学实际应用价值评估体系建设等问题上持续改进。

abstractsThis research focuses on the application of multiple interactive modes in online teaching, combined with the actual teaching cases of the anesthesia equipment course of Xiangya Anesthesiology Specialty of Central South University, showing in detail the preparations for interactive teaching before anesthesia equipment learning, the interaction in online classrooms, the extension of interactive teaching outside the classroom, and the evaluation of interactive teaching feedback mechanism throughout the implementation process. By establishing a "host-guest-viewer" mode, the effect of online live broadcasting is maximized. Through the 360-degree materialized explanation with students as the main body, we will make opening in the pain points and blocking points of online teaching in which students do not go to class and students have no thinking, and promote the improvement of online teaching quality and efficiency. In the following practice, we must continue to work on issues such as the improvement of teacher talent quality, the building of an efficient talent team, and the construction of practical application value evaluation systems for teaching.
