1.概念性变式概念性变式,包括概念变式和非概念变式,其特点是用不同形式的直观材料或事例,来说明概念的本质属性,或变换概念的非本质特征,以突出其本质特征.在高一数学中,有许多概念的教学活动可通过概念性变式,让学生了解哪些是概念的本质特征,哪些是概念的非本质特征,使学生获得对概念的多角度理解,进而掌握新旧概念的本质联系.(1)概念引入变式.引入是概念教学的第一步,
1. conceptual variants conceptual variants, including conceptual variants and non-conceptual variations, which is characterized by different forms of intuitive materials or examples to illustrate the nature of the concept of the concept or transform the concept of non-essential features to highlight Its essential characteristics.In high mathematics, there are many concepts of teaching activities through conceptual variations, so that students understand the nature of the concept of the concept of what is the essence of the concept of non-essential features to enable students to gain a multi-angle understanding of the concept , And then grasp the essential relationship between the old and new concepts. (1) The concept of introducing variants. The introduction of concept teaching is the first step,
