Application of mixed reality technology in clinical teaching of airway anatomy under bronchoscopy / 中华医学教育探索杂志

ABSTRACT

Objective:To explore the effect of introducing mixed reality technology into traditional atlas teaching to teach airway anatomy under bronchoscopy.Methods:A total of 30 Batch 2017 fifth-year clinical medicine students from Shanghai Jiao Tong University School of Medicine were randomly divided into control group and test group by RAND function in Excel, with 15 students in each group. The control group was taught with the traditional bronchoscopic atlas teaching, and the test group was combined with mixed reality technology. The two groups had the same class time. After teaching, the teaching effect was evaluated by examination and evaluation questionnaire. SPSS 25.0 software was conducted for t test and Mann-Whitney U test. Results:The average score after teaching of test group was (61.67±20.15), and that of control group was (36.67±13.32), with statistically significant differences ( t=4.01, P<0.001). According to the questionnaire results, the scores of the test group on course understanding, course concentration, participation, mastery and satisfaction were better than those of the control group, and the differences were statistically significant ( P<0.05). Conclusion:Using mixed reality technology to assist the clinical teaching of airway anatomy under bronchoscopy can improve the quality of students' study and enhance their understanding of the teaching content and students' participation passion, achieving better teaching effect.
