Research On The Geometry Teaching Characteristics Of Excellent Junior Middle School Mathematics Teachers

In order to improve teachers’teaching levels, we should improve mathematics classroom teaching of Junior high schools. In addition, we can also promote the development of teaching reform. In this case, we make fully use of the case methods, literature methods and comparative analysis methods. From classroom videos, guidance of the conference of video and teachers’ reflection diary selected data, we can do some researches. What’s more, we use data analysis methods focus on using video data analysis, quantitative and qualitative data analysis methods.In this paper, we mainly study five junior middle school geometry teaching cases. From the aspect of the teacher’s teaching and teacher-student interaction level, we in-depth analysis of characteristics of geometric classroom teaching. From four aspects of research the creation of scenarios, student activities, using the Geometer’s Sketchpad teaching and the students’ mathematical thinking training, we can make a conclusion:firstly, by means of a visual object or model; secondly, Increase hands-on operation; thirdly, make use of multimedia activation graphics. We find that the basic characteristics of the interaction between teachers and students can be made as follows:focus on changing style, so that the graphics moving up; reinforcement learning motivation, good at adding auxiliary line; to summarize the types of geometric problem solving. In addition, this paper also gives an important teaching design, which provides some reference for the cultivation of new and old teachers’ teaching ability and students’ innovative ability, and gives the corresponding strategies for junior middle school geometry courses.
