Abstract: Objective To explore the effect of clinical teaching model and traditional teaching model on the clinical teaching effect of standardized training for residents in otolaryngology.Methods 27 residents in the standardized training program were selected as the study object. 15 students in experimental group adopt PBL teaching method and 12 students of control group accept the traditional teaching method. Knowledge assessment and a questionnaire survey were conducted to the two groups for comparing and analyzing the practical teaching effect.Results The theoretical examination and skill test in gender, age before the practice has no statistical difference(all P>0.05). After the practice, the theoretical examination showed no statistical difference (P>0.05),but the skills test scores of the experimental group was higher than that of the control group, it showed statistical difference (P＜0.05).The experimental group was higher than that of the control group in the aspects of improving the learning ability, independent thinking ability, innovative thinking ability, practical ability, knowledge of clinical application ability, comprehensive analysis ability. They all showed statistical difference (all P<0.05).Conclusions The PBL teaching method can better motivate students' clinical study enthusiasm and initiative, can improve students' sense of responsibility, and can improve students' comprehensive clinical quality. The model is worth popularizing in teaching.
