An Analysis Of The Attribution Of Junior High School Students' Mistakes In Solving Problems

The algebraic in junior high school mathematics is an important part of "number and algebra",and it is one of the basic teaching contents in junior high school mathematics and is an important knowledge carrier for students to transition from arithmetic thinking in elementary mathematics to algebraic thinking in junior high school.Therefore,it is necessary for students to deepen the understanding of various types of problem-solving errors in the process of learning algebraic related knowledge,to find out the causes of the errors reasonably and effectively,and to work out the teaching strategies in relation to the reduction of students' problem-solving errors.First of all,the topic of studying the problem solving errors of middle school students in algebra teaching in junior high school is settled via the collection,arrangement and analysis of relevant documents' have determined my research object based on all the students in the second year of Grade 15 and Grade 16 and their former math teacher.Then through the classroom observation,collection and arrangement and analysis of the students' homework relating to algebraic,all wrong questions in the test paper and listening to the causes of students' mistakes and other means to continue the paper.Then we collect the students' homework on algebra content and all the wrong questions in the test paper.Based on the error classification theory of Dai Ping and the related learning theory,the paper divides the problem of problem solving into four categories: knowledge error,logical error,strategic error and psychological error.After the general classification of problem solving errors,it presents students' wrong way of solving problems,and makes specific case studies with students' interviews,and further combs and analyzes students' algebraic problem of solving problems.Single calculation error,carelessness is the main.Through the analysis of the types of errors in the examination paper,it is found that the proportion of strategic mistakes is high after the students' homework consolidation exercises.Thirdly,the students and the former teachers were interviewed informally to find out teachers and students' emotion,cognition and behavior toward the mistakes.Through the classroom observation and the analysis of the original teacher's classroom error correctionteaching fragments,the author studies the teaching countermeasures for students' problem-solving errors.Finally,based on the analysis of the students' algebraic problem of solving problems and the investigation of the students' misunderstanding of the problem of solving the problem,this paper further studies the teaching countermeasures against the students' algebraic problem of solving problems,and puts forward some teaching suggestions for reducing the errors of algebraic solving problems of students: emphasizing the teaching of algebraic related concepts and strengthening the algebraic operation rules.Teaching;listening to the causes of students' mistakes in solving problems;correcting students' problem-solving mistakes through class.
