众所周知,美国《州共同核心数学标准》(CCSSM-2010)[1]高中部分设置标(+)号的附加内容,供准备进一步学习微积分、高级统计学或离散数学等高级课程的高中生选学,分布在数与量、代数、函数、几何、统计与概率等5类数学主题中,而作为CCSSM附录A的《基于州共同核心标准的高中数学课程设计》则将之设计为高中第四年课程(本文称为高四)[2],但两者对开课顺序却无规制,这给各州具体实施提供了广阔的操作与
It is well-known that the CCSSM-2010 [1] High School section is provided with the addition of subscript (+) for high school students preparing for advanced studies such as calculus, advanced statistics or discrete mathematics They are distributed in five categories of mathematics topics such as numbers and quantities, algebra, functions, geometry, statistics and probability, while the “High School Mathematics Curriculum Design Based on the Common Core Criteria of the State” in Appendix A of CCSSM is designed as the fourth Year course (referred to herein as the fourth year) [2], but the two have no rules on the order of commencement, which provides a broad operation for the implementation of each state
