Investigation And Research On Plane Geometric Thinking Level Of Junior High School Students Based On SOLO Theory

The teaching of plane geometry in junior high school is conducive to cultivating students' observation,logical thinking and many other abilities.Teaching evaluation is an important part of teaching.How to evaluate the level of horizontal geometric thinking(level)of junior high school students accurately and timely is particularly important.As an important teaching evaluation theory,classification evaluation theory is rarely applied to the concrete evaluation of students' geometric thinking level.This thesis attempts to use the theory as a guide to carry out related research on the level evaluation of plane geometry thinking of junior high school students.This thesis focuses on two issues: firstly,through reading the literature and investigation and research,the exact meaning of the level of planar geometric thinking of junior high school students is expounded,the related topics of congruent triangles are used for detailed analysis and the specific criteria for evaluation by theory are given.Secondly,it collects the final papers of two junior high schools in A city to evaluate them,analyzes the characteristics of students' thinking levels,helps teachers to grasp the process of students' thinking activities more accurately.Then puts forward effective suggestions for plane geometry teaching activities.The main conclusion of this study is that the theory can provide a reference for evaluating the level of planar geometric thinking of junior high school students.It can be seen from the survey results that the students with the single-point structure and multi-point structure level have the most students,and the students who reach the level of the association structure are less.Few students reach the level of abstract expansion structure.It shows that the students of the two schools have a solid grasp of the knowledge of the second semester of the second semester,but they are not flexible enough to use the appropriate methods tointegrate knowledge.Therefore,the teaching of plane geometry requires teachers to guide students in mathematics thinking methods.
