Application of 3D printed model in clinical teaching of hip revision / 中华医学教育探索杂志

ABSTRACT

Objective:To evaluate the effect of 3D printed models assisted teaching method on clinical teaching of hip revision and improve the teaching quality.Methods:Fifty students who were in the standardized training for surgical specialty from Peking University Third Hospital were divided into a control group and an experimental group, with 25 students in each group. The control group was taught by traditional methods, while the experimental group was taught by 3D printed models. After the training, professional theory test and teaching evaluation questionnaire survey were conducted among the members of the two groups, and statistical analysis was made on the students' professional theory test scores, learning interests and teaching satisfaction. SPSS 18.0 was used for t test. Results:The theoretical scores of the experimental group [(84.60±5.76) points] were higher than those of the control group [(78.20±6.90) points], and the difference was statistically significant ( P<0.05). The teaching satisfaction and learning interest of the experimental group were both better than those of the control group [(4.72±0.46) vs. (4.28±0.61), (4.76±0.44) vs. (4.28±0.54)], with statistically significant differences ( P<0.05). Conclusion:The 3D printed model assisted teaching can effectively deepen students' understanding of hip joint structure, improve the teaching quality, and enhance their enthusiasm and initiative in learning.
