Abstract  This article explores the teaching practice of “metal anti-corrosion”,focusing on the application of electrochemical anti-corrosion methods. As choosing “anticorrosion of carbon steel inner tank of electric water-heater” as the task situation, STEM education idea has been penetrated to promote the combination of knowledge and social life, and cultivate “questioning” sense and innovative spirit. At the same time, through the experimental research, the cognitive model of “electrochemical anti-corrosion” has been constructed, and then applied to solving the real industrial problem how to carry out the anti-corrosion design of inner tank of water-heater. During the progress of solving real situation problems, knowledge, method and application has been well integrated and then transformed to the core competences of chemistry gradually.
