符号是数学学科的特有语言,还是数学分析的有利工具,更是数学探索的便捷方法。培养学生的符号意识是数学的重要教学任务之一,因此在教学实践中教师要注意对学生数学符号意识的培养,使学生理解并接受符号,感受并运用符号。在解决实际问题中,培养学生的符号意识,发展学生的抽象思维能力。教师可以通过以下途径培养学生的符号意识:联系生活,利用已有经验,逐步建立学生的符号意识;搭建活动平台,在合作探究中培养符号意识;从抽象到具体,从具体到抽象,在互换练习中培养符号意识。
Symbolic is a unique language of maths, mathematical analysis or an advantageous tool, but also a convenient method of mathematical exploration. Therefore, in the practice of teaching, teachers should pay attention to cultivating students’ awareness of mathematical symbols, make students understand and accept symbols, feel and use symbols. In solving practical problems, we should cultivate the students ’symbolic awareness and develop students’ abilities to abstract thinking. Teachers can cultivate students ’awareness of symbols through the following ways: contact with life, use existing experience to gradually build up students’ awareness of symbols; set up an activity platform to cultivate symbolic awareness through cooperation and exploration; from abstract to concrete, from concrete to abstract, Training for the development of symbolic awareness.
