Study Of Mathematics Communication Based On Classroom Videos

With the reform movement of high-school mathematics education, there are corresponding changes in mathematics communication in classroom. If we want to impart mathematics to student well in classroom,teacher and students must communicate with each other effectively. As an important mathematical ability, the ability of mathematics communication has caused many countries'attentions. Studies about mathematics communication are becoming more and more. Classroom communication includes classroom verbal communication and nonverbal communication, mathematics communication is a dynamic transfer and feedback process of mathematical knowledge, idea and emotion through verbal and nonverbal communication in mathematics teaching. Constructivism believes that Construction of new knowledge must be built on top of a large number of information exchanges.Teachers often dominate communication in traditional classroom, they take the 'teaching-accepting'teaching mode that students lack of initiative and enthusiasm. Mathematics communication is an ongoing reflection, revision and summary process. In this process, there are clear themes and strong purposes,students formed a deep understanding of knowledge. There are still many teachers do not give student more words, and less communication in students. Communication in mathematics classroom is not just teacher teaching students, but teacher and students, students interactive process of cooperation. Problem is the heart of mathematics, and an important means of communication between teacher and students in classroom. Independent exploration and cooperation communication are important ways of learning mathematics.This paper based on existing research, and the general research of classroom communication, combined with the characteristics of mathematics itself, and discussed the form, characteristics and status of communication in the mathematics classroom in new mathematics curriculum reform.Using classroom video analysis, explored some issues of communication in mathematics classroom from verbal and nonverbal communication points. Discussing the status and problems of mathematics communication from the respects of mathematics study, evaluation of teacher and student's willingness to communicate in classroom through the survey.The results show that the status of mathematics communication has greatly improved, but there are still many areas for improvement. Based on theory and survey study, I pointed out the important values of mathematics listening, co-operative learning etc, gave some suggestions for communication in mathematics classroom, and proposed issues for further research.
