几何直观是《数学课程标准(2011年版)》新增加的核心概念之一,它不仅存在于“图形与几何”教学之中,而且更广泛地运用于其他领域内容的学习中,因此教师应当注重对学生几何直观能力的培养。一、几何直观的内涵《数学课程标准(2011年版)》指出:“几何直观主要是指利用图形描述和分析问题。借助几何直观可以把复杂的数学问题变得简明、形象,有助于探索解决问
Geometrical intuition is one of the core concepts newly added in ”Mathematical Curriculum Standard (2011 Edition)“. It not only exists in the Teaching of Graphics and Geometry but also is widely used in the learning of content in other fields. Therefore, teachers Should pay attention to students' ability of geometric intuition. First, the geometric and intuitive connotation of ”Mathematical Curriculum Standard (2011 Edition)“ pointed out: ”Geometry intuition mainly refers to the use of graphics to describe and analyze the problem. With geometric intuition can complex mathematical problems become concise, the image helps to explore Solve the question
