Study of geometry teaching methods that take advantage of the personal computer to encourage the development of ability of students to make geometorical proof

笔者认为，学生几何证明能力的培养，涉及到他们对几何图形的认识，从“实体”到“符号”。 本研究发现，半数的初中二年级学生不能把几何图形看成是“符号”，而只能看成是“实体”。从“解释的教学工具”、“发展问题的教学工具”、“创设发现情境的教学工具”三种类型的数学教学工具来看，在教学过程中，笔者提出了利用计算机辅助教学，培养学生几何证明能力的教学方法。通过对这些教学方法在微机上的教学实践研究，验证了其教育效果。

I considered that the development of ability of students to make geometrical proof involves what they regard the geometrical graphic as , from as a "entity" to as a "symbol". This research reveal that half of the 2 grade junior high school students cannot regard the geometrical graphic as a "symbol" than as a "entity".From the point of view of three types of mathematics teaching tools, "a teaching tool of explanation", "a teaching tool to develop problem" , "a teaching tool to create a context of discovery", I developed the teaching methods that take advantage of the personal computer to encourage the development of ability of students to make geometrical proof. The research in teaching practice on these teaching methods with personal computer verified its educational effectiveness.
