从算术到代数是儿童对于数的认识的一个飞跃。代数概念的概括性比算术更高,它以更一般的形式表达数量关系,因而就更深刻地反映客观世界。从学习算术概念到学习代数的概念,需要更高的抽象思维能力。如果采取符合学生心理特点的措施,促进他们抽象思维的发展,同时在运用已有的算术知识时,注意克服其负迁移的影响,就可使学生从算术概念比较顺利地过渡到代数概念。下面从心理学的角度,来谈一谈应用题的代数解法和算术解法的区别。 From arithmetic to algebra is a leap in children's understanding of numbers. The concept of algebra is more general than arithmetic, and it expresses quantitative relations in a more general form, thus reflecting the objective world more profoundly. From learning arithmetic concepts to learning algebra concepts, you need a higher abstraction ability to think. If we take measures that are in line with the psychological characteristics of students to promote the development of their abstract thinking, while using the existing mathematical knowledge, pay attention to overcome the impact of its negative transfer, you can make students more smoothly from the mathematical concept of the concept of algebra. The following from the psychological point of view, to talk about the algebraic solution to the problem and the difference between arithmetic solutions.
