医学生心脏瓣膜病见习中应用心脏影像三维重建结合VR技术的教学效果研究

The effect of virtual three-dimensional reconstruction of cardiac image in medical students' clinical probation of valvular heart disease

心脏瓣膜病的理论教学中, 传统的授课方式使学习者感觉非常抽象, 学习效果不佳;床旁教学中特定病人的心脏特征无法直接向学习者展示, 学习者难以将理论知识与临床表现进行建构。本研究在基于体验学习理论的临床床边见习的基础上, 利用心脏虚拟影像技术, 将临床病人的心脏影像进行重建, 还原其心脏内部结构, 辅以动态血流图像, 帮助学习者厘清心脏形态结构和血流动力学的关系, 使学习者能够直观地学习这些知识。通过本研究的教学实践发现:高质量的课程设计和引导式的教学结合VR新技术的运用, 能够显著提升学习者的学习体验与效果。

and the learning effect is poor.In bedside teaching,the heart characteristics of specific patients cannot be directly displayed to learners,and learners are difficult to construct theoretical knowledge and clinical performance.Based on the clinical bedside internship based on experiential learning theory,this study uses cardiac virtual image technology to reconstruct the cardiac images of clinical patients,restoring the internal structure of their hearts,supplemented by dynamic blood flow images,to make learners can clarify the relationship between cardiac morphology and hemodynamics,so that learners can intuitively learn these knowledge.Through the teaching practice of this study,it is found that high-quality curriculum design and guided teaching combined with the application of new VR technology can significantly improve the learning experience and effect of learners.
