3D打印模型结合CPBL在脊柱外科专业型硕士研究生教学中的应用

目的探讨3D打印结合CPBL教学在脊柱外科专业型硕士研究生教学中的应用效果。方法选择在我科轮转的42名专业型硕士研究生作为研究对象,随机分为实验组(21人)和对照组(21人)。实验组采用3D打印结合CPBL教学进行教学,课前由授课教师选取典型病例并设计相关问题,课堂结合3D打印模型进行讲解,引导学生思考解决相关问题;对照组采用传统教学方式进行教学。比较两组学员理论及操作成绩,并通过问卷调查了解学员对不同教学的满意度和认可度。采用SPSS 25.0进行独立样本t检验。结果实验组学员的理论、操作成绩及教学满意度、认可度得分分别为(84.7±3.4)、(87.1±3.7)、(9.7±0.3)、(9.3±0.4);对照组学员的理论、操作成绩及教学满意度、认可度得分分别为(79.7±3.3)、(80.4±4.0)、(8.4±0.7)、(8.3±0.6)。组间差异均具有统计学意义(P<0.05)。结论将3D打印技术与CPBL教学相结合;教学效果明显优于传统教学,值得进一步推广应用。

Application of 3D printing technology combined with CPBL teaching mode in postgraduate teaching of spinal surgery specialty

Objective To explore the application of 3D printing technology combined with CPBL teaching mode in the teaching of master's degree in spine surgery.Methods 42 postgraduates in our department were randomly divided into two groups:experimental group(21)and control group(21).The experimental group used 3D printing technology combined with CPBL teaching mode as teaching techniques.Before class,the teacher would select some typical cases and design related problems.During class,3D models were used to guide students to think and solve related problems;The control group used traditional teaching mode.Students in the two groups were compared for the theoretical knowledge and operational techniques they have mastered,and the students'satisfaction and recognition towards different teaching modes were obtained through questionnaire survey.Independent sample t-test was performed using SPSS 25.0.Results The scores of the theoretical knowledge,operational techniques,teaching satisfaction and recognition of postgraduates were(84.7±3.4),(87.1±3.7),(9.7±0.3),(9.3±0.4)in the experimental group,and(79.7±3.3),(80.4±4.0),(8.4±0.7)and(8.3±0.6)in the control group.The difference between the two groups was statistically significant(P<0.05).Conclusion The new teaching mode of combining 3D printing technology with CPBL teaching mode is better than the traditional teaching mode,which is worth further promotion and application.
