Abstract Exercise research is of great value to chemistry teaching in senior high school. Taking the content of “sulfur and nitrogen” as the object of analysis, this paper makes a comparative analysis of the exercises in the senior high school chemistry textbooks of People's Education Press since the reform and opening up from four aspects: the number of exercises, the type of situation, the way of representation and the cognitive requirements. It is found that some changes have taken place in the four aspects of “sulfur and nitrogen” content exercises in the textbook. The writing of exercises presents a change from the focus on knowledge acquisition to the emphasis on the correlation between chemistry and social life, from the emphasis on direct questioning to the emphasis on the diversity of chemical information transmission, from the emphasis on cognitive understanding to the focus on the innovation of students' thinking development. In order to make better use of the textbook exercises, the paper proposes to reasonably grasp the types of situational exercises and effectively improve the function of situational exercises; Pay attention to the intrinsic meaning of text representation and strengthen the use value of chart information; According to the cognitive level of textbook exercises, guide students to achieve thinking development and other exercises using strategies.
