1问题提出欧氏几何的改革，历来受到人们的普遍重视，因历史上曾有“欧几里得滚蛋”的惨痛教训，笔者曾在1996年“21CME展望会”上提出《用现代统一思想方法促进欧氏几何现代化》[1]，并受“21世纪中小学数学课程改革的实验研究”课题组之邀，承担了几何变换实验的子项目任务．
1 issue put forward the Euclidean geometry reform, has always been people's attention, because there have been “Euclid dejected” history painful lesson, the author had in 1996 “21CME Prospects” put forward “with the modern method of thinking Promote Euclidean Geometry Modernization ”[1], and was invited by the research group of“ Experimental Research on Mathematical Curriculum Reform in 21st Century ”to assume the subproject task of geometric transformation experiment.
