This research aims to develop student worksheets (SW) through the study of the effectiveness of chitosan as a coating of corrosion on the metal Zn, Fe, and Al in acidic media, which are valid based on the feasibility aspect of content, language, presentation and graphic. This type of research is the development of research with reference to the development process of the 4-D model of development. Instrument data collection sheet validation is given to three validators, and from analysis of the data obtained on the validity of the feasibility aspects of content, language, presentation and graphic row is equal to 93.88%, 96.67%, 95.83%, and 93.75% with a valid category. Based on the results of limited trials conducted on teachers and students, each obtained an average score of 92.50% and 87.90% with good criteria. It can be concluded that SW developed based on the study of the effectiveness of chitosan as a corrosion coating on metals in acidic media is stated to be valid and can be used in high school chemistry subjects in the subject of reduction–oxidation (redox) reactions and corrosion.
