在教改浪潮中,许多学校和老师都偏离了自己的轨道,把教改弄得过了头,脱离了教育教学的基本原则,公开课成了花架子。本文主要针对这一现象,通过对两节数学教改研究课的对比,说明在教改浪潮中我们教师要坚守一方“净土”——以学生真正掌握知识为根本原则。一切从学生需要出发,以学生掌握知识发展能力为教学的根本目的。 In the tide of reform and education, many schools and teachers have deviated from their own tracks and turned education reform too far out of the basic principles of education and teaching, making it an open shelf.
