探索以“霍乱弧菌检测虚拟仿真实验”为载体的混合式实验教学模式

虚拟仿真实验是一种现代信息化和智慧教学的重要方法，对高等医学院校教学质量的发展起到重要的推进作用。我们自主开发建设的“霍乱弧菌检测与防控虚拟仿真实验”，既弥补了因生物安全问题不能开展的实验教学，也解决了微生物学检验实验教学中存在的操作标准化问题。采用“三步进阶”混合教学模式，实现以“学生为中心”的师生互动模式，创建“设计性实验报告”，与育人元素有机结合，培育医学生的职业使命感。细化考核标准，实现过程性评价。探索课前启发铺垫、课中内化升华、课后巩固拓展混合式实验教学模式，有效提高学生的实验技能，实现知行合一、素能共育的教学目标。

Exploration of blended teaching model based on virtual reality experiment: a case of detection of Vibrio cholerae

Virtual reality experiment is an important approach of modern intelligent teaching, improving the teaching quality in medical colleges and universities. We developed the virtual reality experiment on the detection and control of Vibrio cholerae, which not only made up for the experimental teaching that cannot be carried out due to biosafety issues, but also solved the problem of operation standardization in the teaching of microbiology experiments. The blended three-step teaching model was adopted to realize the student-centered teacher-student interaction. A design-based experiment report combined with education elements was created to cultivate medical students'' sense of professional mission. The assessment standards were refined to realize the evaluation of process. We explored the blended experimental teaching model composed of pre-class inspiration, in-class assimilation, and post-class consolidation and extension to improve the experimental skills of students and achieve the goal of co-education of knowledge (literacy) and practice (ability).
