核心素养下小学“数与代数”教学措施分析

Analysis of the Teaching Measures of "Number and Algebra" in Primary Schools Based on Core Literacy

现代教育体系的改革要求教育活动不仅要对学生的基础知识进行传授与培养,更要求在课堂中培养学生的核心素养与综合素质。数学学科作为逻辑性较强、思维性较强的计算性学科,对于培养学生的逻辑思维、数学思维有着极为重要的作用,而数与代数作为数学课堂的重要构成,主要研究的是数量关系,并揭示其蕴含的变化规律,不仅可以培养学生的数学技巧、巩固学生的数学知识,还可以培养学生的数学素养。本文以核心素养观念教学理念下的数与代数课堂教学措施为中心进行分析,通过引入数学游戏、重视对中低年级学生的引导、珠心算培养数感、将数形结合思想运用到代数课堂中等诸多措施进行分析,希望可以促进数与代数课堂质量的提高,增强学生对知识掌握程度的同时提升学生的数学素养。

The reform of the modern education system requires educational activities not only to teach and cultivate students’basic knowledge,but also to cultivate students’core literacy and comprehensive qualities in the classroom.As a computational discipline with strong logic and thinking,mathematics plays an extremely important role in cultivating students’logical thinking and mathematical thinking.Number and algebra,as an important part of the mathematics classroom,mainly study the relationship of quantity and reveal the law of change contained therein,which can not only cultivate students’mathematical skills and consolidate their mathematical knowledge,but also cultivate their mathematical literacy.This article focuses on the analysis of math and algebra classroom teaching measures under the core literacy concept teaching concept,through analysis and introduction of mathematics games,pay attention to the guidance of middle and low grade students,abacus and mental arithmetic to cultivate the sense of number,and apply the idea of combining number and shape to the algebra class.It is hoped that it can promote the improvement of the quality of math and algebra classrooms,enhance students’mastery of knowledge and improve their mathematics literacy.
