ABSTRACT
Objective:To study the application effects of situation video feedback combined with problem-based learning (PBL) on the clinical clerkship teaching of cardiac surgery for medical students in experimental class of organ-systems-based curriculum (OSBC).Methods:Medical students of Batch 2016 and 2018 OSBC reform experimental class of Jianghan University were selected as the research objects. The study group used situation video feedback combined with PBL teaching method to conduct cardiac surgery clerkship teaching, and the control group used conventional teaching method. At the end of the clerkship, the self-made "Clerkship Satisfaction Questionnaire" was distributed for questionnaire survey and the theoretical test was carried out at the same time. After the course, the theoretical examination was conducted, and the results were compared. SPSS 17.0 was used for t-test and Chi-square test. Results:The clerkship satisfaction investigation results showed that the study group was more satisfied than the control group in such 10 aspects as improving the interest of learning, learning efficiency, the ability of teamwork, clinical thinking, interpersonal communication, combining theory with practice, active knowledge acquirement, language expression, understanding knowledge point, and confidence to become a real doctor. Moreover, there were significant differences in improving the interest of learning, the ability of clinical thinking, and combining theory with practice ( P<0.05). The two theoretical test scores of the study group [(77.46±4.73) points and (79.80±7.53) points] were significantly higher than those of the control group [(70.68±5.16) points and (75.94±8.16) points] ( P<0.05). Conclusion:Situation-based video feedback combined with PBL can improve the clinical clerkship teaching effect of cardiac surgery for medical students under the teaching mode of OSBC.
