关于三角形内角和定理证明的教法反思

Some Thoughts on the Teaching Methods of the Sum of Internal Angles of Triangle

新课程标准的出现,意味着教法坐标体系或者教学深层价值目标的建立.但是在教材与标准之间有如一片广阔的创造地带,它提供给教师前所未有的展示教学智慧的空间,而在创新教法的构想和实施之前,需要对传统教法、新课程标准、教材等有清醒的认识.通过对三角形内角和定理证明教法的剖析,提出了有关新的教学智慧的思考和教学构想.

The advent of the new curriculum standards means the establishment of the normal coordinate system of teaching or of the teaching in-depth value goal. But there seems to be much room of creation between the teaching materials and the standards, which provides to the teacher the unprecedented space of demonstrating their teaching talent. However, before the implementation of the creative innovation in teaching, we need to have a clear idea about the traditional teaching methods, the new curriculum standards, and the teaching materials. Through a comprehensive analysis of the teaching methods of theorem proving of triangle interior angle sum, this paper proposes new teaching thoughts and ideas.
