Abstract The results of cognitive structure test of senior high school students' about "chemical bond" by using the flow map showed that: In the learning process of "chemical bond" concept, most students paid attention to the memory of conceptual words in the process of constructing knowledge, and ignored chemical concepts embodied in the concept of chemical bond, which led students to lack deep understanding of the connotation of related concepts. Cognitive difficulties were mainly manifested in the nature of ionic bond and covalent bond, and formation process of ionic bond, etc.
