Investigation And Research On The Thinking Level Of Solving Triangle Problems Of Grade Two In Senior High Based On SOLO Theory

The knowledge of triangle in senior high school reflects the application of various mathematical thinking methods.The learning of this module can improve the logic of students' thinking.Therefore,how to accurately and timely evaluate the high school students' thinking level of triangle problem solving is very important.At present,the evaluation system used by schools focuses on learners' final learning results,while SOLO theory focuses on learners' understanding level.Based on this,this paper uses SOLO evaluation theory to develop specific evaluation indicators to investigate the thinking level of senior two students in solving triangles.First of all,the thinking process of students in solving triangle problems is combined with the description of thinking level by SOLO theory,the thinking level of students in solving problems is divided,the evaluation standard of each level in the five levels is explained,and the test paper is compiled;secondly,three classes of Grade two in a senior high school are selected to test,and the evaluation index is used.Finally,according to the test results,the students are divided into three groups,the students in group a are the top 10 students in the class,the students in group b are the 11 th to 20 th students in the class,and the students in group c are the 21 st and later students in the class.The main purpose of the interview is to understand the characteristics of problem-solving thinking of senior high school students at each level,and then put forward teaching suggestions.The conclusion of this paper is as follows:1.The thinking level of group a is mostly related structure level.In teaching progress,we should pay attention to the strengthening of the thinking ability of relevance structure and the expansion of the thinking ability of solving complex problems;2.The problem-solving thinking level of group b is mostly multi-point and single point structure level,and the problem-solving thinking level of a small number of students can reach the level of relevance structure.In daily teaching activities,we should pay attention to training students how to interpret mathematical problems;3.The thinking level of group c is single point structure level,and the more complex exercises are pre-structure level.Therefore,in teaching progress,we should pay attention to the explanation of basic questions and the direct application of basic knowledge as the focus of problem-solving training.The introduction of this paper can provide reference for evaluating the thinking level of triangle problem solving of senior two students.
