At present,under the background of the new curriculum reform,on the one hand,computer-aided teaching is a general trend of development.It is a new requirement of quality education to improve students' interest and enthusiasm in learning mathematics and cultivate their mathematical literacy.On the other hand,under the selection function of the Senior High School Entrance Examination,students' problem-solving ability and examination-taking skills are two of the most important issues that both junior students and teachers focus on.In this context,this paper mainly studies the use of basic graphics analysis method in the Geometric Sketchpad software to analyze the dynamic problems of plane geometry in junior high school,and ultimately improve students' ability to solve such problems,providing effective and feasible teaching methods.Firstly,I discussed the effectiveness of the Geometric Sketchpad Software in improving the interest and ability of junior high school students.Then,based on my five-year junior high school mathematics teaching experience,I discussed the convenience and superiority of the basic graphics method in solving plane geometry problems;Then,introducing the dynamic plane geometry problems from Wuhan Senior High School Entrance Examination,I designed a class.I first refined the basic graphics with the help of geometric sketchpad,and collected methods to help students grasp them,through which we got rid of the limitation of the geometric sketchpad.We found the basic graphics directly from the examinations and achieve the goal of getting the marks more quickly.Finally,I have verified my prediction that this teaching method can improve students' problem-solving ability,which shows that my research is meaningful and has certain reference value for the research and improvement of geometry teaching methods of junior middle school mathematics teachers.Geometric Sketchpad software is a teaching tool.The ultimate goal of teaching is to solve the dynamic problems of plane geometry,improve students' ability to solve problems effectively and make them get high marks skillfully.The key to open the door is the basic graphics method.We should use geometric sketchpad but not be limited by it.How to get rid of the shackles of the geometric sketchpad so that students can quickly find the laws and solutions of the dynamic problems of plane geometry in the examination field is a problem that teachers should think about and solve,and the ability that students should master.During the five-year junior high school teaching process,I kept thinking,practicing and summarizing.While my teaching ability was constantly improving,I finally formed this research,hoping to arouse the attention and discussion of other front-line teachers,and effectively enhance students' problem-solving ability.
