初中的数学语言已不单是文字语言,还有符号语言和图形语言,在整个初中阶段符号语言的运用更为广泛.符号可以用来表示数,可以表示数量关系,也可以表示变化规律,还可以进行运算和推理,可以使解题的过程简洁、准确,叙述理由更清晰,便于交流.因此,要学好数学就要重视培养学生对符号的认识和应用意识.一、在概念法则中培养符号意识符号意识的培养要从新知识的学习开始.数的表示除了传统的数据还可以用字母符号表示,教师在教授新课时注意字母符号的引入,要善于挖掘符号信息,提高学生对符
Junior high school mathematics language is not only a literal language, as well as the symbolic and graphical languages, the symbolic language is more widely used throughout the junior middle school.Characters can be used to represent the number, can represent the quantitative relationship, but also that the law of change, but also Therefore, to learn mathematics, we should attach great importance to cultivating students’ awareness and application awareness of symbols.First, cultivate symbolic awareness in the concept of law The development of symbolic consciousness begins with the study of new knowledge, which means that in addition to the traditional data, alphabetic symbols can be used to represent teachers ’introduction of alphabetic symbols while teaching new classes so as to be good at digging symbolic information and improving students’
