Abstract:
Objective:To explore the application effect of case-based learning (CBL), teaching mode combined with 3D printing in clinical teaching of sacral tumors.Methods:A total of 108 undergraduate interns and standardized residency training students who studied in our hospital from 2017 to 2018 were divided into the CBL teaching group ( n = 53) and the CBL combined with 3D printing teaching group ( n = 55) according to their study time. The combined teaching group used computer tomography (CT) data to reconstruct and print out a 3D model of sacral tumors based on CBL, and performed preoperative teaching on the invasion of the surrounding tissues of the tumor. The scores of the students in the two groups were evaluated respectively, and the students were surveyed by self-identification questionnaire (learning interest, self-learning ability, teamwork ability, comprehensive analysis ability and clinical thinking ability). The t-test (one-sided) was used for comparison between groups using stata 14.0. Results:The score of CBL teaching group (75.90±6.70) was lower than that of CBL combined with 3D printing teaching group (83.60±7.40). In terms of critical thinking ability evaluation, self-learning ability, learning interest, comprehensive analysis ability and clinical thinking ability, the CBL combined 3D printing teaching group was superior to the CBL teaching group, and the difference was statistically significant ( P<0.001). In terms of teamwork ability, there was no statistical difference between the two groups. Conclusion:The CBL teaching mode combined with 3D printing can improve academic performance, students' learning interest and clinical thinking ability of sacral tumors in the teaching of undergraduate interns and standardized residency training students.
