微格教学法在中医外科结扎法教学中的应用研究OA

Objective To investigate the effectiveness of the micro-teaching method in teaching traditional Chinese medicine(TCM)surgical ligation techniques.Methods Eighty undergraduate intern physicians were randomly divided into two groups,micro-teaching and traditional teaching,with 40 participants in each.The micro-teaching group used micro-lesson pedagogy and multimedia tools,where students corrected their own errors,guided and critiqued by instructors,with a daily practice of 30 minutes.The traditional teaching group was taught through lectures and demonstrations by instructors,followed by student self-practice of ligation techniques,also for 30 minutes daily.Both groups practiced for 30 minutes daily over a period of 7 days.The number of ligations performed in one minute before and after the study period was compared,along with scores from using a ligation simulator after learning.Real surgical operations were performed by intern physicians under the supervision of teaching doctors,recording the success rate of internal hemorrhoid ligation.A questionnaire survey was conducted among all intern physicians and scored.Results There was no significant difference in the number of ligations per minute between the two groups before the study(P>0.05).Compared to before the study,both groups showed a significant increase in the number of ligations per minute(P<0.05),with the micro-teaching group performing significantly more ligations per minute than the traditional teaching group after the study(P<0.05).There was no significant difference in the scores of deep ligation after learning between the two groups(P>0.05).The success rate of internal hemorrhoid ligation was 90%in the micro-teaching group and 87%in the traditional teaching group,with no significant difference between the groups(P>0.05).Post-learning questionnaire scores were significantly higher in the micro-teaching group compared to the traditional teaching group,with a statistically significant difference(P<0.05).Conclusion The micro-teaching method can increase the number of ligations performed per unit time in TCM surgical ligation teaching,but it does not significantly improve the quality of ligations;however,overall student feedback was better than with traditional teaching methods.
