Research On Unit Teaching Strategies Based On "Numbers And Algebra"

Since the new curriculum reform,the concept of core literacy in various disciplines has been put forward.At the same time,unit teaching has received some attention as a teaching method to promote the formation of students' core literacy.In the elementary school,the layout of the textbooks is based on the children's physical and mental development stage.The content of the same knowledge unit often appears in the textbooks of different grades.This requires teachers to be familiar with the knowledge of the entire elementary school and have a holistic understanding of the knowledge structure of elementary school mathematics.The implementation of integral unit teaching.Based on the "number and algebra" in the primary school mathematics curriculum,this research conducted a unit teaching strategy study of primary school mathematics.The research mainly includes:(1)Through questionnaire surveys and teacher interviews to understand the current status of elementary school mathematics unit teaching,it is concluded that(1)the overall planning of teacher unit teaching is relatively good;(2)the situation of teachers using unit teaching strategies in teaching is positive and the teaching strategies are The selection and use have a certain connection with the teacher's teaching grade,teaching age,professional title,etc.;(3)Teachers will encounter the influence of excessive schoolwork pressure and lack of relevant teaching resources when designing unit teaching.(2)Through the "number and algebra" part of the primary school textbook study,the elementary school mathematics textbook "number and algebra" is distributed in all six grades of textbooks.It is different from "graphics and geometry","probability and statistics","Synthesis and Practice" are arranged alternately,but it is arranged according to the depth of the understanding of numbers,and the two main lines of the learning of the four arithmetic operations related to the deepening of the understanding of numbers are arranged,and the rest of the content is interspersed for learning,and its arrangement has internal units.Sex(3)Through searching the literature and referring to the suggestions of primary school teachers,taking the teaching design of "number and algebra" as an example,some suggestions for the implementation and implementation of primary school mathematics unit teaching are given.
