师生互动模式在线上线下混合式教学中的应用

新型冠状病毒肺炎（以下简称新冠肺炎）疫情期间，各高校按照教育部要求以网络教学平台为依托开展线上教学活动。口腔组织病理学是口腔医学教育的基础学科，其特点为理论与实践结合紧密集合，课程宗旨为提升学生观察、思维、分析和解决口腔疾病问题的能力。师生互动在实习课教学过程中尤为重要。通过改良式BOPPPS为载体嵌入SPOC加翻转课堂方式，结合采用数字切片完成本次线上《口腔组织病理》实习课。课程中采用奖励机制为导向的师生互动模式，较好的提高学生学习“内动力”，在一定程度上解决了无法“面授互动”的遗憾。

Application of teacher-student interaction mode in online and offline mixed teaching

 During the COVID-19 epidemic period, colleges and universities carried out online teaching activities based on online teaching platforms as required by the Ministry of Education. Oral histopathology is the basic subject of oral medicine education, and is characterized by the close integration of theory and practice. The purpose of the course is to improve students ability to observe, think, analyze and solve problems of oral diseases. The interaction between teachers and students is particularly important in practice teaching.In this study, SPOC and flipped classroom were embedded into the modified BOPPPS, the carrier, and digital slices were used to complete the online practice course of oral histopathology.The course adopted the teacher-student interaction mode guided by reward mechanism, which can better improve the students’ “internal motivation” of learning and make up for the lack of “face-to-face interaction” to some extent.
