Objective:To explore the application effect of case teaching(CBL)and task-driven pedagogy(TDL)in biosafety education in medical laboratories.Methods:A total of 68 intern medical students from the laboratory department of a tertiary hospital were selected and divided into control group and experimental group in chronological order,with 34 students in each group.The control group was taught with the conventional method of biosafety belt,and the experimental group was taught by CBL-TDL comprehensive teaching mode.The results of biosafety theory and operation assessment,teaching satisfaction and laboratory biosafety cognition of the two groups were compared.Result:The results of biosafety theory examination,practical operation and the satisfaction with the teaching process and teaching content of application of CBL combined with TDL teaching method of interns in the experimental group were better than those in the control group.All differences were statistically significant(P＜0.05).There were significant differences in biosafety operation behavior between the two groups in four aspects,including biosafety protection,complete normal operation during the experiment,correct waste treatment after the experiment and safety inspection before leaving the laboratory(P＜0.05).Conclusion:The CBL-TDL comprehensive teaching mode is used to teach students in biosafety teaching,which can strengthen the cultivation of students'laboratory biosafety knowledge and improve their practical operation ability,which is worthy of promotion in clinical teaching.
