Analysis And Countermeasures Of The Current Situation Of Students' Arithmetical Ability In The First Stage Of Elementary School

Operation ability mainly refers to the one of correct calculation according to the operation rules.It is helpful for students to develop the operation ability to understand the rules of operations and to find a simple way to solve problems.Having a certain operation ability is the foundation for students' further study,and it is also a basic mathematical accomplishment that citizens in modern society must possess.It is very important to cultivate students' solid computing ability during the first stage of primary school.However,in the first stage of primary school,students' understanding of the value of operation ability is biased.Students are not interested in computing,and they feel that arithmetic is boring.Students' operation ability is uneven and their thinking ability is solidified.Their understanding of computation stays only at the stage of mechanical memory.Students will not be flexible in choosing reasonable ways to solve problems with various algorithms.Therefore,by taking the students of primary school as the study object,this thesis investigates students operation ability in order to enlighten the teaching.This thesis uses questionnaire,experimental method and action research method to investigate the operation ability of primary school students,and interviews with selected students and their teachers to further understand the status of students' operation ability.Using the experimental method,4 classes were selected randomly as experimental classes.Based on the assumption that the teaching intervention on the operation ability of students can help improve students' operation performance,the following conclusions are drawn by sorting out the data.1.As the growth of the grade,the students' life experience and cognitive level and thinking ability have been improved.The average score rates of arithmetic test of grade one,two and three are 82.79%,87.46% and 94.15%,and the score rates are also improving.2.The level of students' operation ability and the degree of "good" and "skilled" also increase with the growth of grade.The degrees of "good" of experimental classesin grade one,two and three reach 82.79%,87.46% and 94.15%,but 79.34%,81.43%and 84.32% for non-experimental classes.The degrees of "skilled" go to 73.35%,81.65% and 90.54% for experimental classes,but 69.24%,71.80% and 72.45% for non-experimental ones.In the experimental classes and the non-experimental classes,the levels of the "good" level are increasing,and the proportions of the experimental classes are higher.However,the proportions of the students in the non-experimental classes have a declining tendency,and some students can not understand why it can be calculated.3.In grade one,two and three,there are cognitive errors(the number of errors,the wrong signs,the careless writing,etc.),which are accounted for 87.42%,79.67%and 64.12%,and the errors gradually decrease with the increasing of grade.However,the knowledge errors(unskilled in the multiplication formula,forgetting the abdication,incomprehension,etc.)are accounted for 12.58%,20.33% and 35.88%,which will increase slowly as the increasing of knowledge.Based on the above survey conclusions,through further analysis of the lack of operational ability,the teaching effect is tested,reflected and optimized,and the following teaching strategies are put forward: 1.Improve teacher-students' understanding of calculation errors.2.Stimulate students' strong interest in learning.3.Develop students' good learning habits.4.Use various algorithms.5.Make calculations clear.6.Train students' multiple calculating abilities,including oral calculation,written calculation and estimation.7.The ability of operation is symbiotic with language expression and thinking ability.
