[Abstract]:Chemistry image language runs through the whole middle school chemistry study stage. Chemistry image not only appears frequently in chemistry teaching and learning, but also is an indispensable link in college entrance examination. However, there is little research on students'understanding of chemical image language. Therefore, it is of great significance to study the language understanding of chemistry images in senior high school students. The research of this paper includes two parts: theoretical research and empirical research. In the part of theoretical study, the key theories of chemical image language are explained, including language, image language and classification of chemical image, and the influencing factors of students' understanding of chemical image language are analyzed and the teaching strategies are put forward. On the basis of theoretical research, this paper organizes questionnaire activities on chemical image understanding of senior high school students in different schools and grades, summarizes and analyzes the results, and draws the conclusion and teaching inspiration of this paper. The results show that the key high school students are better than the non-key high school students in the level of understanding of chemical image language, boys and girls do not have significant differences in the understanding of chemical image language, generally speaking, they are at the same level; With the growth of grade and the accumulation and consolidation of students' knowledge, the senior students have a slow increasing trend in the level of chemical image language understanding. In order to improve students' understanding of chemical image language, the following measures can be taken in the teaching: selecting the appropriate expression of image language, arousing students' interest in learning, strengthening interactive communication. Guide students to explore the meaning of chemical images, guide students to observe, improve students' ability of image understanding, guide students to analyze images, enhance students' ability of image processing, combine theory with practice, and exercise their ability of image understanding in practice. We should pay attention to the cultivation of students' mathematical arithmetic ability and guide them to construct perfect chemistry knowledge system.
