Classroom teaching is an educational activity with teachers and students as the main body,language as the medium and students' all-round development as the ultimate orientation in the classroom situation.Whether the concept of new curriculum reform can be realized in chemistry basic education,it is particularly important to improve the language interaction between teachers and students in chemistry classroom.This study uses the improved Flanders interactive analysis system as a tool,and analyzes the classroom teaching video of both novice teachers and expert teachers with the topic of "ionization of weak electrolytes" from the aspects of classroom teaching interaction structure,teachers' teaching interaction style,classroom emotional interaction atmosphere,classroom questioning interaction characteristics,student interaction behavior and language combination of teaching plate.This paper reveals the differences of classroom language interaction between novice teachers and expert teachers and the characteristics of classroom language interaction between teachers and students.It is found that novice teachers often use the classical language combination of questioning and explanation to organize teaching.They take teacher-class interaction as the main form of interaction,but there is a lack of emotional communication between teachers and students,and the classroom structure tends to be a lecturing classroom with "teacher as the center and knowledge as the goal".Expert teachers tend to use the language combination of heuristic questions to organize teaching,pay attention to the combination of positive indirect language in the process of question and answer,the forms of interaction between teachers and students are rich,and the classroom structure is more inclined to be teacher-led."students as the main body" of the classroom jointly constructed by teachers and students.The common feature of the language interaction between teachers and students in the new chemistry classroom is that teachers' language behavior is the main teaching behavior in the classroom.Teachers are more inclined to directly control the classroom,the proportion of classroom incentive feedback is relatively low,lack of innovative questioning,classroom interaction is mostly question-and-answer interaction,teacher-class interaction is the main form of interaction,student interaction is shown in answering teachers' questions or taking teachers' language,and lack of students to take the initiative to ask questions.
