The Choice And Case Analysis Of The Key Course Of Mathematics Calculation In Primary School

The source of this research is in the course of teaching practice,the students are boring and boring to mathematics calculation.And computational teaching plays an important role in mathematics teaching in primary schools.Finding a better teaching method for the first-line teachers through research.In the study,by changing the previous class classification,the teachers can change teaching strategies more effectively,make the teaching of computational course become vivid and effective,improve the students ' computational ability,and help students to establish effective mathematics cognitive structure,and realize the change learning way of the curriculum standard.The key course of mathematics calculation in primary school is a kind of improvement to the traditional class classification,which divides the traditional new teaching into the key course and the non key course,and the key course is not only the key of the knowledge content but also the teacher's teaching process can make it reach the extrapolate and can transfer positively.This study is mainly carried out through three problems:(1)Why does the elementary school mathematics teacher Divide the computational course content into the key and the non-critical?(2)How to determine the key course of mathematics calculation in primary school?(3)How to teach the key content of mathematics calculation course in primary school? Through the literature analysis,from the structuralism theory,Ausubel Cognitive Assimilation learning theory,gage cumulative learning view,the CPFS structure theory of mathematics learning psychology and some domestic educational practice,combined with the above content,this paper analyzes the theoretical framework of deciding the key course,According to the theoretical framework,the paper determines the content of the key course by analyzing and matching the mathematical knowledge structure.The case of this study selected a class of one famous teacher,this section has the typical characteristics of the key courses,the teaching process of this class is recorded and detailed analysis.According to the case content,this paper analyzes the case,and through case analysis we conclude that teachers should pay attention to the problems in the course of teaching.First of all,to determine what the key courses are;Secondly,in the teaching design of the key course,we should study the principle of knowledge deeply,grasp the key knowledge from the whole content of the knowledge,and then make it reach the goal of migration and extrapolate,and finally clarify the position of the teaching material in the process On the basis of fully grasping the content of teaching,we should improve the textbook design according to the teaching demand.
