符号意识的培养主要有四个方面:一是有主动应用符号去表示数的意识,二是用符号表示数量关系,三是对符号关系式进行简单运算,四是对符号关系式进行代数推理.当前各版本的初中教材,主要强调用符号表示关系式和对关系式进行简单运算,而对主动运用符号去表示数,对符号表达数量关系后进行相关的代数推理重视不够.同时教师在教学过程中对这方面内容亦渗透不够,使得学生的符号意识和其相应的代数推理能力没能得到进一步提升.下面仅列举几个
There are four main aspects to the development of symbolic consciousness: one is the consciousness of using the symbol to express the number, the other is the symbol of the relationship between the quantity, the third is the simple operation of the symbolic relation and the fourth is the algebraic reasoning of the symbolic relation. The current version of the junior high school textbooks, the main emphasis on the use of symbols to represent the relationship and the relationship between a simple operation, and the active use of symbols to represent the number of symbols to express the relationship between the number of algebraic inference is not enough attention.At the same time teachers in the teaching process In this area also infiltrated enough, making the student’s symbolic awareness and its corresponding algebraic reasoning ability can not be further enhanced below to name a few
