几何直观主要是指利用图形描述和分析问题。“几何直观”的思想是重要的数学思想,借助几何直观,可以把数形更好地反映出来。几何直观凭借图形的直观性特点将抽象的数学语言与直观的图形语言、抽象思维与形象思维有机地结合起来,充分展现问题的本质,突破理解上的难点,能有效地帮助学生打开思维大门、开启智慧之窗,体会“以形助数”策略之神韵。
Geometric intuition mainly refers to the use of graphics to describe and analyze problems. The idea of “geometric intuition ” is an important mathematical thought. With the help of geometric intuition, the figures can be better reflected. Geometry intuition combines the abstract mathematical language with the intuitive graphic language, abstract thinking and thinking of the image organically by virtue of the intuitive features of the figure, fully reveals the essence of the problem, breaks through the difficulties in understanding, and can effectively help students to open the door to thinking, Open the window of wisdom, experience “to form a few ” strategy charm.
