学生数学估算意识的培养路径探析

Exploration of the Training Path of Students'Mathematical Estimation Consciousness

在数学学习中,估算是计算能力的重要组成部分。培养学生的数学估算意识,能够增强学生的数感,锻炼学生餡数学观察能力、思考能力及应用能力,对学生数学学习能力的提升、数学学科核心素养的发展具有积极意义。基于此,文章立足数学学科的知识特点及具体学情,探究学生数学估算意识的培养路径,旨在为数学教师提供教学参考。具体路径有:立足教材编排培养估算意识,对接生活元素培养估算意识,结合数学情境培养估算意识,加强专项训练培养估算意识。

In mathematics learning,estimation is an important part of computing ability.Cultivating students'mathematical estimation consciousness can enhance students'sense of number,train students'mathematical observation ability,thinking ability and application ability,and have a positive significance for the improvement of students'mathematical learning ability and the development of the core competence of mathematics.Based on this,this paper,based on the knowledge characteristics and specific learning situation of mathematics,explores the training path of students'mathematical estimation consciousness,in order to provide teaching reference for mathematics teachers.The specific ways are as follows:based on textbook arrangement,cultivate estimation consciousness by docking with life elements,cultivate estimation consciousness by combining mathematical situations,and strengthen special training to cultivate estimation consciousness.
