很多学生在学习了一段时间后仍对几何证明题书写感到困难,思考时没有明确的目的。本文针对这些情况,采取了先集中讲授再平时渗透的方法,提出了从定理的基本要求出发,通过建立表象、组合定理、联想定理等教学对策,从而使学生具备“用定理”的意识。 Many students find it difficult to write a proof of geometry question after studying for some time, and there is no definite purpose in thinking. In view of these circumstances, this paper adopts a method of concentrating on penetrating at ordinary times and puts forward that starting from the basic requirements of the theorem, teaching strategies such as representation, combination theorem and associative theorem are put forward so that students have a sense of “using the theorem” .
