To explore the application value of simulation teaching applied to the teaching reform of interventional radiology teaching micro-courses.

120 cases of interventional radiology students were selected for the study, and they were randomly divided into 2 groups. The control group used micro-course teaching and conventional teaching process; the experimental group used simulated teaching on the basis of the control group. The teaching satisfaction and assessment of the two groups of students were evaluated comprehensively.

There were 58 cases in the experimental group who were satisfied with the teaching method, which was significantly higher than 42 cases in the control group. The satisfaction of the comprehensive evaluation of learning interest, knowledge, vividness of images, theoretical knowledge richness, effective course content, and time content combined with interventional radiology were significantly higher than the control group. After the course, the experimental group's students' satisfaction with the interventional radiology course content was 100% significantly higher than the control group's 96.67% (58/60), χ² = 2.03, P = 0.154. The results of the knowledge theory and interventional radiology time operation performed by the two groups of trainees showed that the theoretical knowledge (93 ± 2.33) of the experimental group was significantly higher than the control group, where t = 29.90, P = 0.000. The practical operation of the experimental group (95.16 ± 1.18). The score is still significantly higher than that of the control group, where t = 0.034, P = 0.009.

The application of simulation teaching in the micro-course teaching can effectively increase the enthusiasm of the students and improve their knowledge of interventional radiology theory and interventional radiology practice. The mastery of operational knowledge is conducive to the mastery of classroom teaching content, improves teaching quality, makes up for the traditional two-dimensional plane micro-class teaching. It is of great significance to the training of interventional radiology talents.
