学生从用数字符号表示生活中的数量关系,到利用字母符号表示生活中的等量关系,是算术思维方式向代数的思维方式发展的一个飞跃,这一飞跃对学生思维层次的提高有十分重要的意义。而小学生长期习惯于算术方法解决实际问题,进入中学后受算术思维定势的影响,很长一段时间不适应代数的思维方式,因此,在小学阶段需加强代数思维方式的训练,加强方程教学。 Students from the number of symbols that the relationship between the number of life, to use the alphabet to represent the equivalent relationship in life, is the arithmetic way of thinking to algebraic way of thinking of a leap forward, this leap in the level of thinking of students is very important Meaning. However, primary school students are accustomed to using arithmetic methods to solve practical problems for a long time. After entering secondary school, they are influenced by the thinking of arithmetic thinking. They are not suitable for algebraic thinking mode for a long time. Therefore, they should strengthen the training of algebraic thinking mode and strengthen the teaching of equations in primary school.
