美国纽约CCSSM 背景下小学数学教学设计的特点与启示

Characteristics and Inspirations of Primary Mathematics Instructional Design under CCSSM Backdrop in New York

2010 年6 月， ccsso 与NGA 共同发布美国《州共同核心数学标准》。目前，全 美各州教育委员会都以CCSSM 作为标准依据开发相应的数学教学材料指导一线的教学教 学。纽约教育委员会发布的小学教学教学设计具有以下特点：严格以CCSSM 为标准开发 教学设计；教学过程结构化；教学过程活动化；教学过程数学化；数学知识应用化；教师主 导教学过程；重视学生数学实践经历的表征。这些特点能为我国正在进行的数学教育改革 提供有益的借鉴。

The Common Core State Standards for Mathematics was released in June， 2010 by the National Governors Association Center for Best Practices (NGA Center) and the Council of Chief State School 0血cers (CCSSO). At present， the Board of Education of each state in US takes CCSSM as standard for developing a corresponding mathematics teaching material to guide mathematics teaching. The Board of Education in New York City released Primary Mathematics Teaching designed with certain characteristics: the development of instructional design should strictly be based on the standard CCSSM; structured teaching process; activities of the teaching process; mathematical teaching process; application of mathematical knowledge; teacherled teaching process; emphasis on students mathematical representation of practical experience. These characteristics have important implications for the reform of mathematics teaching in China.
