A Study On The Classroom Teaching Of The Method Of Combining The Number And Shape Of Low Section In Primary School

Mathematics is a basic discipline,and its ideological and instrumental values are vividly reflected in today's society.The new version of the 2011 curriculum standard puts mathematical ideas in the important position of mathematics classroom teaching.The combination of numbers and shapes plays an important role in students' thinking development and mathematics learning in the lower part of elementary school.In the lower section of mathematics teaching,the teaching of the combination of numbers and shapes is being put forward more requirements.However,in practical teaching,many teachers may still have problems such as insufficient knowledge,weak theoretical knowledge,and inadequate methods.The research in this article can be a useful supplement to the teaching practice of combining numbers and shapes in the lower mathematics classroom of primary schools.This research focuses on: What is the distribution of the relevant class hours and the proportion of class hours in the lower textbooks? How do teachers and students know about the combination of numbers and shapes,thinking,teaching,and learning? What are the main problems and causes? What are the effective strategies for classroom teaching and teaching precautions in low-level mathematics teaching? What are the main classifications of the combination of numbers and shapes in the low-level teaching,and how should typical cases with representative meanings be implemented in teaching? And other issues.Through the method of literature,learning and summarizing the method of combining numbers and shapes in the elementary school category refers to the mathematical ideas generated by the two major subjects of "numerical" and "shape" in "combination" or transformation and application.The theoretical basis of the combination of numbers and shapes is the theory of representation and constructivist learning.Study the new curriculum standard's teaching goal on "combining numbers and shapes with thinking methods",and count up 272 lessons related to the lesson in the lower textbooks,accounting for more than 80%.Through the survey method and interview method,the problems and reasons for the implementation of the combination of mathematical and ideological methods from students,teachers,and classrooms were found.The results showed that the teachers in the sample schools had good infiltration of numbers and shapes in their classrooms,and the students' awareness rate was high.However,students also have problems such as inadequate drawing,non-standard drawing,and inadequate integration.Teachers attach more importance to the combination of mathematical and ideological methods.Due to lack of theoretical knowledge,single teaching methods,inaccurate teaching materials,and insufficient analysis of student problems,As a result,the teaching effect is not high,the students' evaluation is not in place,and the problem of incomplete placement is properly demonstrated.Through case studies and classroom observation methods combined with their own teaching practices,an effective teaching strategy is proposed: improving self-cultivation,paying attention to the combination of numbers and shapes;digging into the content of textbooks,aiming at the combination of numbers and shapes;grasping the main body of students to achieve mathematics integration.In teaching,we should pay attention to: reasonable cut-in,point-by-point;multi-evaluation,based on students;combination of numbers and shapes,complementarity and win-win;strict requirements for correct demonstration.In teaching,it is divided into two categories: "helping numbers with forms" and "solving numbers with numbers".With the help of intuitiveness of lines,students can understand numbers,understand the calculation of numbers,understand mathematical concepts,and understand the meaning of questions.And logic can quantify graphics,explore laws,describe graphic locations and movements,use typical cases to analyze classroom practice and test the effectiveness of teaching strategies.The typical case of classification and study of numbers and shapes combined with ideological methods helps teachers to accurately find the entry point and effectively complete teaching goals.At the same time,students can more accurately grasp the nature of knowledge and feel the connotation of numbers and shapes combined with ideological methods.
