Research On Junior High School Students' Ability To Solve Plane Geometry Problems

The curriculum standard of Compulsory education takes "figure and geometry" as one of the four learning modules of mathematics subject,indicating the importance of plane geometry in junior middle school mathematics.Junior middle school is a leap period to improve students' logical thinking ability.Learning plane geometry is the most effective way to improve students' mathematical abstraction,logical reasoning and mathematical operation ability.For students,the study of plane geometry is also a great challenge: first,the abstraction of geometric concepts increases the difficulty of students' understanding;Secondly,it is difficult to standardize the expression of geometric language.Moreover,complex graph analysis is difficult;Finally,logical reasoning ability improves difficulty.In this situation,this study is of great significance.Research revolves around "plane geometry problem solving ability" concept,both at home and abroad about mainstream mathematics,junior high school plane geometry teaching and problem solving are studied,the plane geometry problem solving ability is defined as: on the same stage of learning of students,students to solve the plane geometry problem solving speed how fast or students in the same situation can help solve the problem of plane geometry in terms of ease,this paper combined two performance were studied.In line with the Angle,round,triangle,parallelogram,part four summarizes the basic method of junior middle school plane geometry problem solving strategy,to investigate whether the fourth chapter summarizes problem-solving strategies really effective help,in this paper,we adopt the experimental investigation method: on the same level of two classes,one class as the experimental group,another as the control group,during the test,the teacher in the teaching of subjects class emphasis on problem solving skills and strategy,focus on students' mathematics thought method,and the other class normal order of teaching.A month later,the academic performance of the two classes was compared again,and the experimental class' s performance was indeed greatly improved.Thus draw the conclusion: cultivating middle plane geometry problem solving ability,in the first place to cultivate the students good habits of the topic,then inspire the student to actively use problem-solving strategies in the process of problem solving,to guide the student to review after the problem solving reflection,formed the problem solving model,based on the above research,problem-solving strategies are given demonstration teaching cases and provide reference for teachers.
