几何教学内容的选择和处理一直是数学课程改革的热点问题 .六七十年代以来 ,数学教育界有不少人主张削弱传统的欧氏几何 ,激进派甚至提出“欧几里德滚出去”的口号 .当前几何教学内容的改革 ,也受到数学教育界的极大关注 .笔者认为 ,研究美国学校数学的几何内容改革 ,也许对我? The selection and processing of geometry teaching content has always been a hot issue in the mathematics curriculum reform. Since the 1960s and 1970s, many people in the mathematics education field have advocated the weakening of the traditional Euclidean geometry. The radical faction even proposed that “Euclidean get out”. The slogan. The current reform of the geometry teaching content has also received great attention from the mathematics education community. The author believes that the study of the geometric content reform of American school mathematics may be for me.
