Research On The Problems And Countermeasures Of The Teaching Of Plane Graphic Area In Primary School

As a bridge between integers and decimals,the calculation of fractions has an extremely important significance for students in senior primary schools.At the same time,the calculation of calculus is different from the calculation of integers,which varies greatly and is highly difficult,resulting in a high error rate of calculation.This paper is based on the collection of relevant calculation level and the study of fraction calculation.The author has carried out an investigation and research on the actual situation of the score calculation level of the senior students in a school in his area.First,the author explores all kinds of math algorithms used in elementary school math,and tests all types of fractions involved.The test results show that,on the whole,the error rate of score calculation is high,especially the serious loss of score multiplication and score division.The specific types are as follows:When the maximum common factor is not found,the calculation amount increases;The final result is not reduced to the simplest fraction;Incorrect application of operation law leads to simplification error;Careless copy wrong number or did not notice that there is a minus sign before parentheses need to change sign,etc.At the same time,questionnaires were made for front-line teachers and students with learning difficulties,and in-depth interviews were conducted to further classify and analyze students’ mistakes.It is concluded that there are not only subjective reasons,such as weak knowledge base and interest,but also some objective reasons,such as incomplete teachers and abstract points of knowledge,which affect the accuracy of students’calculation.This article puts forward strategies and suggestions from the perspectives of students themselves,teachers’ teaching methods and teaching materials.If students want to strengthen the calculation of fractions,they must have a deep understanding of arithmetic,so as to really apply the algorithm;At the same time,students should strengthen their interest in computing and realize the importance of computing.This requires teachers to stimulate interest into students according to their cognitive level and existing experience;Teachers should also change the single style of teaching,a variety of effective teaching methods combined;In terms of teaching materials,teachers can selectively integrate teaching materials to strengthen the close connection between knowledge and make students more coherent in learning fractional knowledge.
