Research On The Reasons And Countermeasures Of Junior High School Students' Operation Mistakes

Operation ability regarded as one of the ten core concepts of mathematics is the necessary ability of junior high school students and the basis of math learning.The math level of junior high school students not only affects the math scores,but also has a certain impact on the development of other subjects,and even has a certain impact on the development of high school and university majors in the future.The importance of mathematical operation ability determines the degree of its attention.However,with the development of The Times and the progress of science and technology,the wide use of computers and other high-tech electronic products has led to the decline of the computing ability of modern junior high school students.With the continuous advancement and deepening of curriculum reform and the proposal of math core concept,aiming at the current situation of math operation of junior high school students,the class of math operation should also be changed,so that students should build themselves,experience the class,and constantly improve the ability in the process of meaningful learning.Under the background of this operation,the paper summarizes a large number of documents.The paper selects eighth-grade students to investigate with the integral expression of battles and factoring as feasible test questionnaire content design.After that,the paper organizes and analyses the data and with the help of the interview method of students and teachers to carry out mathematical operation communication,further understand the current situation of junior high school students' mathematical operation,analysis of the reasons for students' mistakes.The paper refines the reasons for junior high school students' mathematical operation mistakes from the objective factors and subjective cognition,intelligence factors and non-intelligence factors,internal factors and external factors.On this basis,on the theory of curriculum reform and the cultivation of the core accomplishment,experience to construct education class as the goal,with the reform and development of thinking to explore the methods and strategies of ascension junior middle school students operation ability,it is concluded that mathematical classroom needs a variety of teaching wisdom and strategies such as competition system in the group to inspire students' interest in operation,with the specification of classroom teaching to improve the students'operation in imperceptible habits,improve the operation through the study of the basic concept of the solid structure and comparison of examples to explain and to broaden the operation thinking to promote students' operation ability and use appropriate classroom evaluation mechanism to help students improve the self-correcting.
