Abstract Under supervision of the teacher, students acquired a deeper understanding through project-based learning entitled “Reexploration of the principle of electrochemical corrosion of steel”. This article introduced how teachers have proposed, designed and implemented this project. In addition to typical electrochemical corrosion of metals, students also learned oxygen concentration cell corrosion and found a simple criterion to identify oxygen concentration cell corrosion. After completing the project, students employed mind maps to reconstruct the knowledge network of metal corrosion principles and corrosion prevention methods.
