Abstract:Objective To explore the application effect of “self-designed experiment” teaching model which based on virtual simulation software in magnetic resonance imaging experiment teaching. Methods A total of 94 undergraduates majoring in imaging technology at grades 2018 and 2019 in West China Clinical Medical College of Sichuan University were recruited for the study, they were divided into 2 groups: traditional teaching group (48 students, 2018) and “self-designed experiment”teaching model group (46 students, 2019), the traditional teaching group adopted the traditional teaching mode of “teacher demo-student operation”, while the “self-designed experiment”teaching model group adopted “self-designed experiment”teaching model. The results of in-class tests and the completion of experimental reports of the two groups were compared and analyzed. Results The in-class test score of the “self-designed experiment” teaching mode group, which was (15.56±2.01) points, was higher than that of the traditional experimental teaching group, which was (12.81±3.12) points, with statistically signi?cant difference (P<0.05)|compared with the traditional teaching group, the number and proportion of students in the “self-designed experiment”teaching model group were signi?cantly increased in terms of observation of magnetic resonance signal acquisition, result and error analysis, summary of experimental rules. Conclusion The teaching mode of “self-designed experiment” based on virtual simulation software is bene?cial to the performance of the software in the magnetic resonance experiment teaching, which is helpful to improve the students’ comprehensive qualities such as the ability of combining theory with practice, analyzing and solving problems, practical operation ability, innovation and scienti?c research ability.
