几何画板色彩斑斓的直观显示可激发学生发现所展示的数学知识,甚至去思索更深层次的数学本质,有助于培养学生数学抽象思维能力,继而高效地突破一些教学的难点,比如:数学概念的描述(旋转的概念)、公式定理的推导探究(勾股定理)等。文章将以探讨“几何画板”在勾股定理及其逆定理的教学中辅助作用为例,挖掘如
The vivid and colorful visual display of geometrical drawing board can stimulate students to discover the mathematical knowledge they show and even think about the deeper mathematical nature. It helps to cultivate students’ abilities to abstract abstracted mathematics and then breaks through some teaching difficulties efficiently. For example, Description (the concept of rotation), derivation of the theorem of theorem (Pythagorean theorem) and so on. The article will explore the “Geometric Sketchpad ” in the Pythagorean Theorem and its inverse theorem teaching auxiliary role, for example, mining
