Typical Errors And Countermeasures Research Of Junior High School Students To Solve The Dynamic Geometry Problems

Junior dynamic geometric problems is based on a geometric transformation, in view of changes in motion to explore the geometry variation. “Pattern transformation”as one of the important objectives of teaching junior high school geometry in "Full-time Compulsory Education Curriculum Standard(trial version)2001", let students to understand process value in the dynamic geometry observed during conjecture, hands,plausible reasoning. With the diversification of the development of mathematics questions exam content, knowledge and ability test content dynamic geometric problems involved more widely, the exam difficulty is gradually increasing, which gives teachers teaching and students learning has brought great difficulties. Therefore,the study of dynamic geometric problems can not only provide students with a number of problem-solving ideas and methods, but also can promote the development of teaching.In this article, in perspective of junior dynamic geometric problems problemsolving strategies, by analysis feature in recent years exams and dynamic geometry questions in Chongqing and present situation on learning dynamic geometric problems.Conducted a questionnaire test and questionnaire about the dynamic geometric problems to 120 students at Chongqing YuCai middle school, case by the student answers the dynamic geometric problems and student interviews, understand the student to solve dynamic geometrical reasons for typical errors and problems. Through the analysis of dynamic geometry problem questionnaire, understand students’ learning and mastering in dynamic geometry problem situation, thus to put forward the basic problem-solving strategies for junior middle school dynamic geometry problems and some teaching suggestions.Through to the students to solve dynamic geometric analysis of the reasons for the typical errors and problems as well as the students learning situation and the problems of dynamic geometric knowledge in statistical analysis, From the perspective of the problem solving process put forward the basic strategy to solve dynamic geometryproblem, move in, static system of static and dynamic braking. From the dynamic geometry teaching is put forward in the direction of the teaching suggestions as follows,Strengthening process geometry basic concepts, properties and theorems of teaching,strengthen the teaching of mathematics reading and numeracy skills, strengthening research problem solving strategies, pay attention to the cultivation of students’ nonintelligence factors.
