培养学生用方程解决问题的“基础、能力与思想”——例谈小学数学列方程解决问题的教学策略

Cultivate Students'"Foundation,Ability and Thinking"to Solve Problems with Equations——Examples of Teaching Strategies for Solving Problems by Formulating Equations in Elementary School Mathematics

方程是学生认识数量关系过程中的一个飞跃与转折点。本文将从“重视方程基础,建立未知数和已知数的等价意识;培养代数意识,强化等量关系的构建能力;感受方程思想,体会方程在解决问题上的思维优势”这三个方面来提高学生用方程解决问题。

Equation is a leap and turning point in the process of students'understanding of quantitative relations.In this paper,we will pay attention to the basis of equation,establish the equivalent consciousness of unknown number and known number,cultivate algebraic consciousness,strengthen the ability of constructing equal relation,feel the thought of equation,and understand the thinking advantage of equation in solving problems.To improve students using equations to solve problems.
