| Classroom interaction is the most obvious existence in classroom teaching,and its research has naturally become one of the most important fields in teaching research.Domestic and foreign researches on classroom interaction mostly use quantitative research methods or qualitative research methods to analyze the verbal interaction between students,and less use quantitative and qualitative research methods to explore the verbal and nonverbal interaction between teachers and students in classroom interaction.The study uses quantitative and qualitative methods to analyze the phenomenon of mathematics classroom interaction in primary school.The video classroom of Kunming Spring City was selected as the research object of 9 famous primary schools.The coding table of the interactive analysis coding system based on information technology and the improved Flanders interactive analysis system transcribes and encodes the text of 9 classroom teaching records with the help of NVivo11 video analysis software,so as to transform them into quantifiable data.According to the analysis of data,multi-dimensional description and analysis of the way,subject and characteristics of primary school mathematics classroom interaction.The study found that: on the whole,teacher-student verbal interaction is the main way of primary school mathematics classroom interaction;Classroom interaction is dominated by teacher’s language,the discourse power of teachers and students is relatively balanced,and students have a certain discourse power and learning space;Teachers’ teaching efficiency is high,and there is almost no silence that is not conducive to teaching;Information technology has increased the way and effect of teacher-student interaction.According to the above research results,the characteristics of primary school mathematics classroom interaction are as follows:(1)teachers play a leading role in classroom interaction;(2)Primary school mathematics classroom is a democratic and open classroom;(3)Teacher student interaction is the main type of teacher-student interaction;(4)Teachers’ classroom utilization rate is high;(5)Teachers use technology to build a platform for classroom interaction;(6)The interactive mode of "teacher’s question-student’s response-teacher’s evaluation or feedback" has been formed.According to the above research conclusions,this paper puts forward the Enlightenment of optimizing primary school mathematics classroom interaction:(1)teachers choose different ways of interaction to regulate students’ participation in interaction;(2)Teachers should optimize the way of questioning and expand the scope of interaction;(3)Teachers should make effective and specific evaluation or feedback on students’ answers to promote the benign development of teacher-student interaction;(4)Teachers use educational technology to assist classroom teaching and promote the diversification of interactive methods. |
