盲生由于视力残疾,丧失了视觉这一最为重要的感觉器官,对于学习高中阶段的数学知识来说,迫切需要适合他们认知水平和能力的一套方式方法,以尽可能多的帮助他们解决自身认知水平和学习数学需要的抽象知识之间的矛盾。本文是笔者通过几年来盲校高中数学教学工作,着重从表象对辅助盲生理解诸如圆锥曲线方程等平面坐标等问题的理解。 Blind students who lose vision, the most important sensory organ due to their vision disabilities, are in urgent need of a set of modalities appropriate to their level of cognitive and competencies to learn the mathematics of upper secondary school to help them as much as possible Conflicts between their level of cognition and the abstract knowledge they need to learn math. This article is the author through several years blind school high school mathematics teaching, focusing on the appearance of auxiliary blind understanding of such as conic equations such as plane coordinates and other issues of understanding.
