Investigation And Analysis Of Students' Problem-solving Errors In Solid Geometry Teaching In Senior Two And Strategy Suggestions

Solid geometry is a very important part of high school geometry,the score in the college entrance examination is generally 17-22 points,solid geometry problem-solving error has been a topic that teachers and students attach great importance to,for liberal arts students,space imagination ability is worse than science students,learning solid geometry is very difficult,teachers also teach very distressed.By the second year of high school,students have adapted to high school life,it is a good time to sprint.In order to better guide teachers' classroom teaching,improve teachers' teaching skills,optimize students' learning ability and reduce problem-solving errors,it is particularly important to investigate and analyze students' problem-solving errors in solid geometry teaching in senior two.This study selects senior two liberal arts students and mathematics teachers from a key middle school in Jiangxi Province,mainly interviews teachers,questionnaire survey,test paper analysis and interviews with students.This paper mainly focuses on the following questions:(1)what are the main problems in the process of solving solid geometry,and how can these problems be classified?(2)What are the main reasons for these mistakes?(3)In order to effectively avoid these mistakes,how should teachers do in teaching?Through this study,the students' problem-solving errors are classified according to the primary and secondary,the first is the knowledge error,the second is the logical error and normative error,and the last is the psychological error.The main reasons for these errors are:(1)vague memory of definitions and theorems;(2)ignorance of concepts in class and nonstandard writing after class;(3)memorizing formulas but not using them;(4)poor mathematical foundation and sense of space;(5)bad habits and repeated mistakes;(6)weak logical thinking ability and reasoning difficulty;(7)psychological "trouble" and death It's easy to give up.In view of these mistakes,this paper puts forward some suggestions for teachers' Teaching:(1)pay attention to the concept and reveal the essence;(2)summarize the theorem and form a framework;(3)do a good job in demonstration and refine the process;(4)when solving problems,teachers should learn to let students find fun in the process of solving problems;(5)learn to guide students in time and train their thinking;(6)combine various teaching methods To improve the efficiency of the classroom;(7)to train students to do a good job in error correction,review the old habits.It is hoped that this study can help teachers to understand the causes of students' problem-solving errors and optimize,teaching learn design to help students reduce problem-solving errors.
