The Interaction Study Between Teachers And Students In Junior High School Mathematics Concept

“Teaching activities are the process of active participation,interaction and common development between teachers and students.” As the organizer and director of students' learning,teachers should ensure effective teacher-students interaction in the class,so that students can achieve learning goals in vivid,lively and personalized classroom activities.It's of vital importance for students to understand mathematical concepts correctly,which is help them to master basic knowledge and skills.As the most important mathematical knowledge,mathematical concept is the basis for mastering other mathematical knowledge and skills.This study is based on the theoretical research,the performance of the teacher-students interaction,which types can be divided into the question subjects,responses,discussion types,emotional communication and silence the five types of 16 kinds of behaviors.And combined with classroom video,qualitative research and quantitative analysis are carried out on the specific performance of classroom teacher-students interaction in the typical mathematical concept teaching video,summarizes the characteristics of teacher-students interaction in mathematical concept course in junior middle school.It hopes that the teacher-students interaction characteristics in this study can help junior high school mathematics teachers to expand the concept teaching more effectively.The specific conclusions are as follows:First,during the process of introducing concept,teacher-students interaction is often adopt the way of technology to students and the teacher questioning methods,arouse the enthusiasm of students' learning concept and awake them existing experience,which is intuitive and inspiring;second,in the stage of formatting concept,teacher-students interaction utilize the form of problem string and discussion,so that students can gradually grasp the common attributes of mathematical concepts in the learning activities of observation,comparison and discussion,which is enlightening and instructive;third,during the stage of conceptual understanding,the teacher-students interaction is mostly use to let students to think more and analyze problems,which is helpful for students to clarify concepts and has the enhancement and initiative;forth,in the stage of concept consolidation,various interactive behaviors act together to provide certain guarantee for students to obtain complete mathematical concepts study,which is of consolidation and diversity;fifth,in the stage ofclass summary,the teacher-students interaction often use inductive way of combing knowledge context,and then to make the students have a systematic understanding of the concept,leading the students to comprehend mathematical thinking method again,and it has the summary and the development.
