Application of batch CBL combined with PBL teaching method in clinical practice course of laboratory medicine
J Objective To explore the feasibility and effect of applying batch problem-based learning(PBL)combined with case-based learning(CBL)to practice teaching for laboratory medical undergraduates.Methods The subjects of the study were 24 undergraduates,including 8 males and 16 females,aged 22-23 years,who practiced in the clinical laboratory of the First Affiliated Hospital,Sun Yat-sen University from June 2022 to April 2023.According to the setting of professional groups in the clinical laboratory,the teaching method of batch CBL and PBL was adopted in the teaching of microbiology inspection major,and the traditional teaching method was adopted in the teaching of other majors.Through the questionnaire survey,the students'learning effect and teaching satisfaction were compared under the two teaching modes.Wilcoxon signed rank test for two paired samples was used.Results Compared with the traditional teaching method,the batch CBL combined with PBL teaching method improved the learning interest(Z=3.015,P=0.003),self-learning ability(Z=3.908,P＜0.001),problem solving ability(Z=3.033,P=0.002),practical operation ability(Z=2.213,P=0.027),comprehensive analysis ability(Z=3.245,P=0.001),teamwork ability(Z=2.054,P=0.040),and clinical communication ability(Z=2.565,P=0.010)and inspire the clinical thinking(Z=3.014,P=0.003),with statistically significant differences.The students had a high degree of recognition for the teaching method of batch CBL combined with PBL,and 100.0％(24/24)of the students were very satisfied with"teaching contents adhering closely to the syllabus"and"teaching content related to clinical diagnosis and treatment".Conclusion The application of batch CBL and PBL teaching method has a good teaching effectiveness in clinical practice course of laboratory medicine,which is helpful to enlighten the students'clinical thinking and can be adopted as an adjunct to traditional teaching method.
