抽象是数学教学的特性之一,是数学教学中经常性和普遍性的思维活动。与其他学科不同,数学学科本身就是抽象学科,数学知识都是经过抽象得到的,抽象性是数学的基本特征。抽象指的是在思想中抽取事物的某个属性而撇开其他属性的逻辑方法,学生能够客观的面对抽象数学知识,有利于学生真正理解和掌握教学内容,对提高学生数学水平具有十分重要的意义。数学抽象教学具有一定难度,纵观数学抽象教学实情可见,有时教师会因为“自我定位”教学观
Abstraction is one of the characteristics of mathematics teaching, which is a frequent and general thinking activity in mathematics teaching. Different from other disciplines, mathematics itself is an abstract discipline, mathematical knowledge is obtained through abstraction, abstraction is the basic characteristics of mathematics. Abstraction refers to the logical method of taking a certain attribute of things aside from other attributes in the mind. Students can objectively face abstract mathematical knowledge, which helps students to really understand and master the teaching content. It is very important to improve students’ mathematics level significance. Mathematics abstraction teaching has a certain degree of difficulty. Looking at the facts of mathematics abstraction, we can see that sometimes teachers may be confronted with “self-orientation” teaching concept
