文化视角下的勾股定理教学设计

Teaching Design of Pythagorean Theorem from Cultural Perspective

勾股定理是根深叶茂的世界数学之树不可分割的一枝,世界各国都非常重视勾股定理的文化价值.另外,勾股定理的证明过程中蕴含了丰富的数学思想方法,它是对学生进行数学思想方法教育的良好素材,也为数学研究性课题的学习提供了丰富资料.因此,在九年级的复习课中,通过挖掘勾股定理的三种典型证明方法中所蕴涵的数学思想方法以及所展现的古今中外数学家们创造过程中广阔而生动的人文背景,促使学生从学习中获得成功的享受和进一步学习的动力,实践多元文化的关怀.

Pythagorean Theorem, well - world of mathematics. Much importance established and vigorously - developed, is has been attached to the cultural value of an indispensable part in the Pythagorean Theorem in the countries all over the world. Besides,the process of proving Pythagorean Theorem implies abundant mathematical methods of thinking, which can not only be good materials for teaching mathematics methods of thinking but also provide rich resources for learning mathematics research projects. For these reasons, we explore the mathematics methods of thinking contained in three typical proof techniques of Pythagorean Theorem in the review lessons of the Ninth Grade,as well as the broad and vivid cultural backgrounds of mathematicians at all times and in all o-ver the word which displayed during the process of their creating these methods. All this will supply the students with a sense of achievement in their learning in order to motivate them to learn further, thus realizing the muhicul-tural concern.
