新课程标准对几何内容作了较大调整,推理论证作为传统的难点现在已大大削弱,取而代之的是观察与比较、操作与解释等新颖的几何题.这类考题是通过动手操作、图形的旋转、翻折及文字语言、符号语言、图形语言的转换等,引导我们切切实实关注、体验学习的过程,重视知识的发生过程, The new curriculum standards made a great adjustment to the content of the geometry. The theoretical difficulty as a traditional difficulty has now been greatly weakened. Instead, new geometric problems such as observation and comparison, operation and interpretation have been replaced. Such questions are through hands-on operation and graphic rotation. The translation, translation, and conversion of text language, symbol language, and graphic language guide us in the process of earnest attention and experiential learning, and emphasize the process of knowledge generation.
