理性思维,作为一种特殊的思维形式,不可能像数学知识一样通过讲授、灌输来完成教学。我们要在概念形成的不同阶段,采用不同的方式来促进学生的理性思维发展。课程标准认为数学在形成人类的理性思维过程中发挥着独特的作用:通过学习数学,学生表达清晰,思考有条理,逐步形成了实事求是的态度~([1])。概念是理性思维的基本形式,是数学活动的重要组成部分,因此,我们要关注如何在概念形成中,发展理性思维。
Rational thinking, as a special form of thinking, can not complete the teaching through teaching and instilling the same knowledge as mathematics. We should adopt different ways to promote the development of rational thinking in different stages of concept formation. The curriculum standard holds that mathematics plays a unique role in forming the rational thinking of human beings: by learning mathematics, students express their opinions clearly and systematically, and gradually form a realistic attitude (1). Concept is the basic form of rational thinking, is an important part of mathematical activities, therefore, we should pay attention to how to develop the concept of rational thinking.
