数学共同核心国家标准(CCSSM)是许多有意改善数学教育的利益相关者(如教师、学区数学领导和课程开发人员)关注的主要焦点。本文报告了初中(6-8)数学课程中与几何领域相关的具体内容转变。采用的方法允许对多个标准文件的内容进行比较。我们报告了一些关于中学几何教学内容的戏剧性变化。我们发现，在这项研究分析的八个州中，至少有六个州(57%在6年级，50%在7年级，50%在8年级)，52%的中年级学生对几何CCSSM的学习期望将是新的年级水平。基于我们对CCSSM和CCSSM之前的国家标准的分析，我们还强调了三个领域，这些领域代表了中等年级的“新”几何内容。
The Common Core State Standards for Mathematics (CCSSM) is a primary focus of attention for many stakeholders' (e.g., teachers, district mathematics leaders, and curriculum developers) intent on improving mathematics education. This article reports on specific content shifts related to the geometry domain in the middle grades (6–8) mathematics curriculum. The methodology employed allows for comparisons of content across multiple standards documents. We report on some dramatic changes with regards to the geometry content taught in the middle grades. We found 52% of the middle grades geometry CCSSM learning expectations will be new to the respective grade level at which they are taught in at least six of the eight states analyzed in this study (57% in grade 6, 50% in grade 7, and 50% in grade 8). We also highlight three areas that represent “new” geometry content at the middle grades based on our analysis of CCSSM and pre-CCSSM state standards.
