一、培养学生推理論証能力的重要性几何的研究对象是图形性貭。用推理論証的方法来研究图形性貭,可以解决不能用度量或实驗来解决的問題,也可以避免由使用工具而发生的一些誤差,而且带有普遍性。例如,三角形的內角和是180°,如果用度量的办法来研究,只能得到近似的結果,而且每次度量的三角形都是一个有固定大小和固定形状的三角形,带有特殊性,缺乏普遍性。如果用推理論証的方法来研究,就可以得到正确的結論,而且推导的过程和所得的結論,对
First, the importance of cultivating the ability of students to reasoning geometry The object of study is graphical 貭. The use of reasoning argumentation methods to study the graphical 貭, can not solve the problem can not be measured or experiment, but also to avoid the use of tools and some error occurred, but also with the universality. For example, if the interior angles of the triangles are 180 °, only the approximate result will be obtained if we study them by means of measure. And each measured triangle is a triangle with a fixed size and a fixed shape, with particularity and lack of universality. If you use the method of reasoning to study, you can get the correct conclusion, and the derivation of the process and the conclusions obtained, the
