In the class, the first step is to conduct a pre-assessment to understand the students’ preview situation, and adjust the teaching content appropriately. Next, cases were led in and questions were put forward to attract students’ attention and guide them into a learning state. Then, the students were engaged in a series of participatory learnings, including group discussions and representative statements after the teacher explained knowledge points through animated demonstrations and clinical real test reports, and further thinking and discussions based on the summary and questions of the teacher. And then, a post-assessment was conducted to evaluate the learning effectiveness of students. Finally, the teacher summarized the key content of this lesson.
