Causes analysis of death is the most common work in forensic pathology practice. When designing problem-based learning (PBL) teaching objectives

we should take cause analysis of death as the main line and give consideration to other related issues. The selected cases should be typical ones that solve the target problems

which can fully reflect the basic theoretical knowledge of forensic pathology

and have moderate difficulty

delights and clear conclusions. The PBL course is divided into three steps. The first step focuses on providing students with case information to guide them to find out the problems that need to be solved. The second step focuses on discussing the problems and making pathological diagnoses. The third step focuses on answering the question raised at the beginning of the course. Each lesson can also be divided into several sections by which the lesson plans should be prepared. In the teaching process

performing active interaction with students

controlling the direction of classroom development

balancing student opportunities should be done well in order to make the curriculum smoothly and achieve the purpose of teaching.
