Abstract: Objective To implement and evaluate the teaching effect of a blended outcome-based education (OBE) mode in laboratory course of human respiratory system. Methods From September 2019 to December 2021, a total of 562 undergraduates of clinical medicine enrolled in 2017 and 2019 in Zhejiang University School of Medicine who participated in the course of functional experiments joined this research. Three hundred and twelve students from grade 2019 were assigned to be the experimental group and 250 from grade 2017 were organized to be the control group. The students of control group were trained by classic offline respiratory animal experiments and adopted a blended online/offline teaching mode. In addition to offline respiratory animal experiment, the training of students of experimental group was supplemented with a new human virtual simulation experiment which adopts the OBE-oriented blended online/offline teaching mode. The teaching effect was evaluated by performance analysis and questionnaire survey for experimental group students, and data was analyzed by t-test. Results The final examination scores and the total scores from experimental group and that from control group are significantly different as [(13.6±1.6) vs. (12.2±2.5),(12.0±0.6) vs. (11.5±0.9)] (all P<0.001). The result of questionnaire survey in experimental group showed that students scored the mode of OBE-based human virtual simulation experiment higher than that of offline animal experiment in stimulating learning interest [(4.1±0.7) vs. (3.5±0.5)] and learning efficiency [(4.0±0.8) vs.(3.7±0.8)] and encouraging active participation [(4.2±0.7) vs.(3.6±0.8)]. The differences were statistically significant (all P<0.001). Conclusions OBE-based human virtual simulation experiment improves students’ learning outcome and optimizes teaching effect in the laboratory course of respiratory system experiment and the new mode is well recognized by students.
