数学思想蕴涵在数学知识形成、发展和应用的过程中,是数学知识和方法在更高层次上的抽象与概括。因此,在教学过程中,教师要通过创设说理课堂,引领学生在积极参与教学活动的过程中,通过独立思考、合作交流,逐步感悟数学思想。下面笔者以罗鸣亮老师《四边形分类》一课教学为例,谈谈如何在创设说理的数学课堂中,引领学生感悟数学思想。一、在梳“理”对话中,体会分类思想【片断一】师:四边形为什么要分类? Mathematical thinking is implicated in the process of the formation, development and application of mathematical knowledge, which is the abstraction and generalization of mathematical knowledge and method at a higher level. Therefore, in the process of teaching, teachers should lead the students actively to participate in teaching activities through the creation of reasoning classrooms, through independent thinking, cooperation and exchange, and gradually realize the mathematical thinking. The following author to Luo Mingliang teacher “quadrilateral classification” teaching as an example, talk about how to create rational mathematical lessons, leading students to seize the mathematical thinking. First, in the comb “management ” dialogue, experience the classification idea [piece a] Division: why the classification of quadrilateral?
