Research And Teaching Strategies On Junior Middle School Students’ Barriers In Solving Dynamic Geometry,Problems

"The Compulsory Education Mathematics Curriculum Standards(2011 edition)"will be "graphic change"as seven to nine grade one of the important goals of graphics and geometry teaching,let students experience the graphic abstract,classification,properties,determination of grafics,to master the basic knowledge of graphics and geometric and basic skills." In recent years,the mathematical proposition of the central examination has been diversified,and the dynamic geometric problem has become the focus of the examination,and the knowledge involved have become more and more extensive.The difficulty of the test has gradually increased,which brings great pressure to the teaching of teachers and students’ learning.Therefore,it is important to study the obstacles and countermeasures to the dynamic geometry of the middle school,and to improve the teaching.Based on the teaching of the dynamic geometry of middle school,this paper makes a statistical analysis of the dynamic geometry problems in the junior middle school mathematics test in Jiangxi province in the past five years,and the 107 students in the two classes of Hongdu middle school in Nanchang city have distributed the test questionnaire and questionnaire.By analyzing the questionnaire results,we can understand the students’ learning situation(learning interests,study habits,etc.)and grasp the situation.In order to solve the problem of solving dynamic geometry problems in junior high school students,the author puts forward corresponding teaching strategies.After analysis,this paper summarizes the problems of solving dynamic geometry problems in junior high school students,and lacks the comprehensive analysis of the graphic movement process,and it is difficult to master the nature of the problem.Lack of reading comprehension ability to extract effective information;Poor operational capability;The thought process is simple,the thought is not clear;The interference effect of undesirable psychological factor and so on.From the perspective of dynamic geometric problem teaching,the following teaching suggestions are given to help students develop confidence in solving dynamic geometric problems,deepeningstudents’ understanding of geometric concept formation process,using Sketchpad to enhance the intuitiveness of dynamic geometry teaching,training students’ mathematical reading ability and operation ability,and teaching the strategies of problem-solving.
