华师大孔企平教授说过:“空间观念的形成,只靠观察是不够的,教师还必须引导学生进行操作实验活动。”而数学课程标准的基本理念之一就是倡导学生积极主动、勇于探究的学习方式。因此,在几何的教学中教师要引导学生通过观察、操作、实验等活动强化感知,建立表象,真正介入概念、定理等的产生过程,这样才能切实做到提高几何教学的实效。笔者在教授沪教版八年级数学《矩形的判定》一节时,尝试让学生动手操作,自主探
Professor Kong Qiuping of China Normal University said: “The formation of the concept of space is not enough by observation alone. Teachers must also guide the students in conducting experimental activities.” One of the basic concepts of mathematics curriculum standards is to promote students’ initiative and courage Exploring ways to learn. Therefore, in the teaching of geometry, teachers should guide students to intensify their perceptions and establish appearances through observation, operation and experiment, truly intervene in the process of producing concepts and theorems so as to effectively improve the effectiveness of geometry teaching.
