摘要本研究从案例撰写和以问题为基础的学习（problem-based learning，PBL）的实施体会两个方面展开探讨。PBL案例需依据专业要求，体现专业特色。定位于应用型人才培养的卫生检验检疫专业案例可融入相关实验技能项目；同时案例撰写形式根据主题拓展形式差异，设计为并联式案例与串联式案例，以适用于不同范围的课程整合。在PBL教学实施中，学生学习状态是课堂讨论效率的关键，它决定了PBL实施方式是完全自主学习还是嵌入式讲授；教师需建立合作学习氛围，从而提高课堂讨论效率。

abstractsThis paper discusses from two aspects of case writing and PBL implementation experience. PBL cases should be based on professional requirements and reflect professional characteristics. Health inspection and quarantine cases targeted at application-oriented talent cultivation can be integrated into relevant experimental skills items. At the same time, the forms of case writing are expanded according to the differences of theme forms, which are designed as parallel cases and serial cases, so as to be applicable to the curriculum integration in different areas. In the implementation of PBL teaching, students' learning status is the key to the efficiency of classroom discussion, which determines whether the implementation of PBL is completely autonomous learning or embedded instruction. Teachers should establish cooperative learning atmosphere to improve the efficiency of classroom discussion
