Proteins are the embodiment of life activities, and their targeting is crucial for cells to perform their normal functions. Protein sorting is one of the key and difficult points in the teaching of Cell Biology. Currently, the content of protein sorting is mostly scattered in different chapters, making it difficult for students to construct an overall knowledge. This article analyzes the knowledge composition characteristics of the protein sorting section, and combined with the analysis of students’ academic situation, creates an instructional design based on modular construction and map navigation. Integrate the content of protein sorting in the textbook into a comprehensive knowledge module, which is divided into the first and second parts. The first part mainly focuses on the sorting of secretory proteins, namely, co-transport, and the second part mainly focuses on the sorting of non secretory proteins, namely, post-transport. The two are organically connected. Combining the path of protein sorting with map-based navigation teaching, the teaching method with illustrations and texts is more conducive to students’ systematic learning of this part of knowledge, better connecting relevant knowledge scattered in various chapters, and improving students’ logical thinking ability, comprehensive analysis ability, and transfer application ability.
