《义务教育数学课程标准(2011年版)》首次提出了“几何直观”这一核心概念,并指出“:几何直观主要是指利用图形描述和分析问题。”这里的解释并非严格的概念界定,但我们也可以从中把握几个关键特征:其一,几何直观是一种描述和解决数学问题的方法,它与“直观几何”的区别在于,后者是指几何学中的一个研究领域,主要研究包括认识图形、进行立体图形与平面图形的转换等内容。其 The Compulsory Education Mathematics Curriculum Standard (2011 Edition) first proposed the core concept of Geometry Intuition and pointed out that geometric intuition mainly refers to the use of graphics to describe and analyze problems. “” The explanation here is not strict Concept, but we can also grasp several key features: First, geometric intuition is a way to describe and solve mathematical problems, which is different from “intuitive geometry ” is that the latter refers to the geometric A research area, the main research, including understanding of graphics, graphics and plane graphics, such as the conversion. its
