Problems And Strategies For Teaching Estimation In The Upper Primary Years

Many problem situations will appear in real life.Some practical problems can be solved smoothly only by ensuring a certain degree of accuracy.No preci se calculation results are required,and the estimation is much simpler.As an effective method of reasoning and judgment teaching,estimation teaching has always been valued by people in the field of modern education in my country.However,in the actual teaching process,the intensity of the estimated teaching research,what problems will be encountered in the estimated teaching,etc.,still need to be studied in depth.The teaching of mathematical estimation and estimation has become a hot topic in the current international research on mathematical education.The promulgation of the Compulsory Education Mathematics Curriculum Standard(2011 edition)has further affirmed the important status of "estimation".However,it is found through research that teachers still have problems in their teaching practice,such as unclear estimating teaching goals,students’ low awareness of estimating,difficulty in grasping estimating teaching process,difficulty in optimizing estimating methods for students,single evaluation of estimating teaching,and inflexible application of students’ estimating strategies.This article mainly provides an overview and analysis of estimation and relate d concepts,and in-depth study of the actual situation of estimation teaching in prim ary schools from the perspective of teachers and students in practice,aiming at the main problems existing in the teaching of mathematics in primary schools in our country.Question,it was discussed.Find out the main problems that are common in the teac hing of mathematics estimation in primary schools at present,analyze the common problems in the estimation teaching,and analyze the reasons,using the scientific conclus ions drawn from the world’s research related to estimation as a guide,and propose a kind of Specific methods and means that can effectively solve problems in actual teaching.The main research adopts various research theoretical methods such as relevant literature analysis,questionnaire survey,data analysis,etc.The research object is the teachers in the senior years of Yanyuan Road Primary School.Through investigation,research and analysis,it is found that the main problem of estimating teaching is:Estimation teaching is not emphasized,the evaluation of estimation teaching is too single,the estimation training frequency is insufficient,and the teacher’s own estimation knowledge reserve is insufficient.At the same time,further analyze the reasons,so as to get the solution strategy of the problem in the estimation of teaching in the senior years of elementary school.Analyze from the three levels of school,teacher and student.Including that schools should consider including estimation courses in the scope of the examination,optimizing the configuration of estimation teaching m aterials for senior years,and strengthening the training of teachers’ estimation awareness and teaching skills;teachers should set clear estimation teaching goals;flexibly adjust estimation teaching methods and optimize estimation teaching Strategies design;students should actively cooperate with the classroom activities of estimation teaching,strengthen the learning of estimation in connection with the reality of life,and change the understanding and attitude of estimation.Through the research,I hope to provide some valuable and reference suggestions for the elementary school estimation teaching,and put forward ideas for further research in the future.
