根据学生的认知水平可以将几何概念划分为以下几个层次:直观概念、分析层次的概念以及由一些公理系统所“生成”的概念。小学阶段以前两个层次的概念学习为主。在几何概念认识的教学过程中,如果能够以具体知识为载体找到合适的时机渗透相应的数学思想,不仅可以有效地促进学生数学活动经验的积累,而且能够让学生触及知识的本质,加深对知 According to the cognitive level of students, the concept of geometry can be divided into the following levels: the concept of intuition, the concept of level of analysis and the concept of “genesis” by some axiomatic systems. Primary level before the two levels of concept-based learning. In the teaching process of geometric concept cognition, if we can find the right opportunity to penetrate the corresponding mathematical thought with the carrier of specific knowledge, we can not only promote the accumulation of students’ experience in mathematics activities effectively, but also enable students to touch on the essence of knowledge and deepen their understanding of knowledge
