Research On Senior High School Students' Cognitive Level Of Solving Triangles Based On SOLO Classification Theory

Solving triangles is an important part of high school mathematics,which can effectively cultivate students' core literacy such as logical reasoning and mathematical modeling.At present,there is little research on the cognitive level of solving triangles of senior high school students,and SOLO classification theory is a qualitative evaluation method that pays attention to students' learning process and quality.Therefore,based on SOLO classification theory,this paper studies the cognitive level of solving triangles of senior high school students from the following two questions:(1)what is the cognitive level of solving triangles of senior high school students under SOLO classification theory?(2)What are the factors that affect the cognitive level of senior high school students in solving triangles?Through the research,this paper draws the following conclusions:1.High school students' cognitive level of solving triangles:(1)more than 60% of the two dimensions of the test paper are at or above the level of relevance structure,can master the knowledge of solving triangles,and the cognitive level of basic knowledge of dimension I is higher than the practical application of dimension II;(2)The two dimensions of the test paper have significant correlation,that is,the learning relationship between the two dimensions is close;(3)From different grades,the cognitive level of grade three is higher than that of grade two;(4)From the perspective of different classes,there are significant differences in cognitive level between senior two classes;There is no significant difference in cognitive level between senior three classes;(5)From the perspective of different gender,there is no significant difference in students' cognitive level.2.Factors affecting senior high school students' cognitive level of triangle solution:(1)students do not fully grasp basic knowledge;(2)Students lack confidence and interest in learning;(3)Students lack good learning methods and habits;(4)The influence of teachers' teaching experience and ability;(5)The influence of teachers' teaching ideas.According to the above research conclusions,this paper puts forward some teaching suggestions for teachers to improve the cognitive level of high school students in solving triangles,hoping to bring inspiration and help to teachers' teaching.
