Abstract: This paper explores the application of medical science popularization in undergraduate teaching of human parasitology. The teaching method using medical science popularization can not only enhance students' understanding and memory of parasitology knowledge, but also cultivate their autonomous learning ability, communication skills and sense of social responsibility. It proposes to enrich teaching methods through various forms such as multimedia resources, interactive platforms and practical activities, and carry out targeted science popularization education according to the characteristics of different parasitic diseases. In addition, combined with the practical experience in human parasitology teaching, this paper describes in detail the organization and implementation of the "Parasitic Disease Science Popularization Week" series of activities, and makes a preliminary evaluation of the activity effects. Finally, it puts forward issues that should be paid attention to in the implementation process, such as teaching norms, content centralization and resource diversification, hoping to provide new ideas for human parasitology teaching.

Key words: human parasitology, medical science popularization, teaching quality, teaching method innovation, comprehensive quality of students, practical exploration, undergraduate teaching
