Detailed learning procedure. Both PRI-E group and LBL group needed theoretical knowledge and clinical practice. The learning of the two groups went through three stages: before class, during class and after class. The duration of each of the two teaching methods is consistent (80 min), including before (10 min), during (60 min), and after (10 min). During the six-month rotation of learning, the frequency of the two learning methods is once a week.
