Abstract Effective integration of multiple representations is an effective strategy to promote students' in-depth understanding of scientific concepts. This study integrates the contents of three multiple representations frameworks in the field of science education, and designs the teaching of “primary battery” in the compulsory module of high school. Firstly, guide students to learn the macro device, micro principle and electrode symbols of primary battery in turn, and preliminarily construct the concept of primary battery. Then, based on the related representation of hydrogen and oxygen fuel cell, the two-dimensional model diagram of primary battery device principle is constructed to understand the concept of primary battery. Finally, the two-dimensional model diagram of primary battery in daily life is used to realize the representation transformation and solve practical problems, realize the deep understanding of the concept of primary battery.
