In response to the issues of insufficient student motivation and initiative,as well as low classroom learning efficiency in the teaching process of Database System Principles,in order to enhance the teaching effectiveness of the course on Database System Principle and Application,an analysis was conducted on the nature of this course and its current teaching status.Subsequently,a process oriented guided inquiry learning(POGIL)teaching model for Database System Principles was proposed and implemented in the teaching of Database System Principle and Application.Taking the database normalization teaching content as an example,a complete POGIL activity was described in detail,including the structure and content,the roles and tasks between students and teachers during the activity,and how to design POGIL activity.
