Objective　To explore the comparative advantage of Team based learning (TBL) in common diseases teaching among pre-selected trainees for medical non-commissioned officer. Methods　200 trainees were randomly divided into two groups of equal size (each having 100 trainees)

one TBL group and another lecture based learning (LBL) group as the control group. The teaching content was both Chapters of High Altitude Illness and Hypertension. In the LBL control group

the traditional lec-ture based teaching and learning manner was followed. In contrast

the trainees in the TBL group were assigned pre-lecture self-learning outline and questions to discuss in advance

team-based group dis-cussion was conducted

and scene simulation with typical disease case analysis were adopted in class. In both groups

the teaching effectiveness were evaluated by both exam test and questionnaire manner. Results　It turned out the team based learning model resulted in significantly improved overall trainee assessment scores (88.90 ± 5.28 vs. 76.10 ± 5.12

P＜0.05) and higher overall teacher satisfaction scores (8.63 ± 0.85 vs 7.18 ± 0.72

P＜0.05)

compared to the LBL group. Conclusion　TBL model is more effective in improving trainees' capabilities of cultivating team work spirit

self-confidence

learn-ing enthusiasm

problem analysis and knowledge application． TBL model significantly brings more advantage in teaching pre-selected trainees for medical non-commissioned officer.
