Abstract: Objective To explore the application effect of ADDIE teaching mode in ultrasound diagnosis. Methods A total of 153 imaging students who studied in the Department of Ultrasound in the First Hospital of Lanzhou University from September 2020 to June 2022 were selected as the research objects. According to the method of random number table, they were divided into the conventional group and the observation group. The students in the conventional group received the teaching of ultrasonic diagnostics in the conventional teaching mode(n=73). Students in the observation group received ultrasonic diagnostics teaching under the ADDIE teaching model(n=80), the differences between the two groups of students in the course assessment results were compared, the two groups of students' satisfaction with the teaching content were examined with questionnaire, the teacher's satisfaction with the students were evaluated and compared. Results The results of the observation group were significantly higher than those of the conventional group(P<0.05). The scores of students in the observation group were significantly higher than those in the conventional group in the aspects of ideology and politics, teaching content, teaching method, teaching management and teaching effect(P<0.05). The scores of students in the observation group in independent learning, classroom activity, learning interest, class notes and homework completion were significantly higher than those in the conventional group(P<0.05). Conclusion The application of ADDIE teaching model in the teaching of ultrasound diagnosis can achieve better teaching results, help improve students' academic performance and teaching satisfaction, and also significantly improve the satisfaction of teachers to students.
