Study on the effect of combined application of digital slice-based micro-lectures with flipped classrooms in the practical teaching of oral histopathology
Objective The study investigated the application effects of a teaching model that combines digital slice-based micro-lectures with flipped classrooms in the practical teaching of oral histopathology.Methods The study was conducted from September 2021 to January 2023 in the network class at the Teaching Center of the Third Affiliated Hos-pital of the Air Force Military Medical University.The study included 44 students from grade 2019(control group)and 45 students from grade 2020(research group)majoring in five-year undergraduate in oral medicine at the Third Affiliated Hospital of the Air Force Military Medical University.In the practical teaching of oral histopathology,the research group adopted the teaching model based on digital slices combined with micro-lecture and flipped classrooms,while the con-trol group used traditional teaching methods.After all courses ended,a satisfaction questionnaire survey was conducted among the students.The practical course grades and the results of the satisfaction questionnaire survey for practical teaching were compared between the two groups.Results The results showed that the practical course grades of the re-search group were(94.98±2.16)points,significantly high-er than the control group[(92.18±2.15)points],with a statistically significant difference(t=6.123,P＜0.001).The satisfaction questionnaire survey results indicated that there were statistically significant differences between the research group and the control group in terms of im-proving self-learning ability,creating a good classroom interaction,appropriate teaching methods,stimulating interest in learning,and deepening the understanding of theoretical knowledge(Z values were 3.161,3.369,2.282,2.561 and 2.797 respectively;P values were 0.002,0.001,0.023,0.010 and 0.006 respectively).Conclusion The teaching model that combines digital slice-based micro-lectures with flipped classrooms can effectively improve the learning efficiency of oral histopathology practice classes for stomatology undergraduates,stimulate students'learning enthusiasm,mobilize students'enthusiasm,and enhance teacher-student communication,which is an effective method to improve the teaching effect of oral histopathology practice.
