数学是一门非常严谨的学科,也是一门理性的科学,同时也是一门抽象的科学。纵观小学、初中、高中的数学知识可以看到学生学习的数学知识是从直观转向抽象、从感性转到理性、从数字转向概念的过程。小学生在学习数学时,由于他们当前的心理特征,他们关于理性表达知识的概念非常贫乏,这时学生只会凭自己的想法做最简单的语言表达,他们在表达数学内容时,常常会让人听不懂,也给他人的理解造成歧义。教师培养小学生的数学语言表达能力,实 Mathematics is a very rigorous discipline, but also a rational science, but also an abstract science. Throughout the elementary, middle school, high school mathematics knowledge can see that students learn mathematical knowledge from intuitive to abstract, from sensibility to rational, from the digital to the concept of the process. When pupils learn mathematics, because of their current psychological characteristics, their concepts about the rational expression of knowledge are very poor. Students can only make the simplest language expression by their own ideas. When they express mathematics, they often make people Do not understand, but also to others to understand the ambiguity. Teachers develop pupils’ ability to express themselves in mathematics
