多渠道提升学生数学几何直观能力素养探究

Exploration of Improving Students'Intuitive Ability of Mathematical Geometry Through Multiple Channels

几何直观是利用图形来描述和分析问题,将复杂的数学问题变得简明形象,有助于学生的数学学习。从具体数学几何实践教学来看,部分学生几何直观能力较弱,而教师在授课中对几何直观能力的重视度也不高,导致这些学生的几何直观能力与所处的年级段不匹配。针对这些问题,教师有必要挖掘课堂深度、厘清教学内容、反思总结教学,拓宽几何直观能力培养的覆盖面,将其覆盖到更多的数学领域之中,以提高数学课堂教学质量。

Geometric intuition is the use of graphics to describe and analyze problems,to make complex mathematical problems concise and visual,and to help students learn mathematics.From the practical teaching of mathematical geometry,some students'geometric intuitive ability is weak,and teachers pay little attention to geometric intuitive ability in teaching,which leads to the mismatch between the geometric intuitive ability of these students and their grades.In view of these problems,it is necessary for teachers to excavate the depth of the classroom,clarify the teaching content,reflect on and summarize the teaching,broaden the coverage of geometric intuitive ability training,and cover it to more mathematical fields,so as to improve the quality of mathematical classroom teaching.
