A Study On The Characteristics Of Teacher-Student Interaction In High-quality Mathematics Lesson Of Primary School Based On CLASS

Teacher-student interaction is the key to classroom teaching and an important indicator of teaching quality.In elementary school mathematics teaching,good teacherstudent interaction not only helps to establish a positive teacher-student relationship,but also helps students accumulate experience in mathematics activities,develop image thinking,and cultivate logical thinking ability in the process of interaction with teaching,thereby achieving primary mathematics education goals and improve the quality of primary school mathematics education.This study starts with high-quality classes and discusses the characteristics of teacher-student interaction in high-quality mathematics classes in primary schools,providing suggestions for improving the level of interaction between primary school mathematics teachers and students.In this study,the purpose sampling and stratified sampling were used to select 30 "one teacher one excellent course" from the national education resources platform,taking the theory of constructivism and symbolic interaction as the theoretical basis,using the literature method,classroom observation method and case analysis method,and with the help of CLASS(Classroom Assessment Scoring System)to observe,count and analyze,the purpose is to reveal the interaction between teachers and students in the high-quality class of primary mathematics from the three fields of emotional support,classroom organization and instructional support of CLASS general and individual characteristics.The research shows that: first,the overall level of teacher-student interaction in the highquality mathematics course in primary school is high.The teacher-student interaction in high-quality mathematics class in primary school is the best in the field of classroom organization,followed by emotional support and instructional support,which are all in the upper middle level.Secondly,there are significant differences in emotional support and classroom organization in the interaction between teachers and students in different grades of primary school mathematics high-quality courses,specifically in the dimensions of positive atmosphere,behavior management,respect for students’ views and teaching activities.There are differences in the dimensions of cognitive development between the high-quality courses in different mathematics fields.Finally,the interaction between teachers and students in the high-quality mathematics course in primary school has the following characteristics: positive atmosphere of interaction between teachers and students,diversified subjects of interaction between teachers and students,orderly process of interaction between teachers and students,teacher-student interaction reflects the learning process of mathematics,and visualization of interaction thinking between teachers and students.Based on the analysis of the characteristics of teacher-student interaction in high quality mathematics classes in primary schools and the current situation of teacherstudent interaction in most normal classes,this paper puts forward practical suggestions from CLASS of three aspects.First,pay attention to students and create a positive interactive atmosphere in mathematics class.By paying attention to the starting point of students’ mathematics learning,it emphasizes the cultivation of students’ positive emotion in mathematics learning;pay attention to the students’ classroom generation and improve the sensitivity of teaching;pay attention to the autonomy of students and promote the diversification of interactive subjects.Second,optimize the management,give play to the effectiveness of primary school mathematics classroom organization.To guide students’ problem behavior positively by clarifying classroom behavior norms;rational planning of teaching activities to promote the optimization of teacher-student interaction;to strengthen the diversity of the interaction between teachers and students.Third,the activation of thinking,enhance the classroom interactive teachers teaching support.To promote the cognitive interaction between teachers and students by paying attention to effective feedback;focus on mathematical expression and promote the development of students’ mathematical language ability;construct a learning community and promote the development of teachers’ professional quality.
