Abstract Through the comparison and analysis of the new and old curriculum standards and teaching materials, the cognitive mode, big concept and teaching objectives of the aqueous solution theme are determined. The appropriate situational materials are selected around the teaching objectives, and the unit teaching is guided by the big concept. In the process of solving the real problems, the basic perspective and thinking of students’ understanding of aqueous solution are developed, and the development of students’ core literacy of chemistry is promoted.
