上海市中小学已全面执行新的课程标准,初中数学全面使用新教材。新教材从内容上看,删除了老教材中一些过繁过难且用处不大的内容,引进了符合现代潮流的新内容;从体系上讲,改变过去的“公理、定义、定理”的逻辑推理体系,而将内容分为“基本”“拓广”“发展”三部分,平面几何分为“直观几何”“实验几何”“论证几何”,有利于初学者入门。新教材主要目的是减少教学内容,调整教学要求,从而减轻 Shanghai’s primary and secondary schools have fully implemented new curriculum standards, and junior high school mathematics has fully used new teaching materials. From the content point of view, the new textbook has removed some of the old textbooks that are too complex and difficult to use. It has introduced new content that meets modern trends; systematically speaking, it has changed the logic of past “axioms, definitions, and theorems”. Reasoning system, and the content is divided into “basic” “widening” “development” of three parts, plane geometry is divided into “intuitive geometry,” “experimental geometry,” “argument geometry,” is conducive to beginners entry. The main purpose of the new textbook is to reduce teaching content and adjust teaching requirements so as to reduce
