Abstract By analyzing the content structure of the introduction of the three latest revised compulsory teaching materials for senior high school chemistry, it concluded that teachers should transform teaching from the introduction to the preface, and sublimate the understanding of the textbooks. It is necessary for teachers to reconstruct the preface of the textbook from four dimensions, including the description of the textbooks’ compilation intention, the subject characteristics and development introduction, the main content and characteristic analysis of the textbook, and the interpretation of the subject’s educational value and the learning suggestions, as well as enlighten students’ understanding and structured thinking of the subject and textbook, and to be the advance organizer of the overall understanding of the subject.
