数学表征是学习数学知识、解决数学问题的一个重要过程。《学校数学课程和评估的标准》(美国数学教师协会,2000)强调:数学教学计划应该强调表征,以促进数学理解,使得所有学生:创造及使用表征,组织、记录与沟通数学概念;有目的、弹性及适当地发展数学表征;使用表征去描述或诠释物理的、社会的与数学的现象。由此可见,数学表征活动在学生理解和应用数学过程中的意义和作用。综观当下的数学课堂,虽然很多教师意识到数学表征的重要性,但学生的表征活动存在被动、单
Mathematical representation is an important process of learning mathematics and solving mathematical problems. The School Mathematics Curriculum and Assessment Criteria (American Association of Mathematics Teachers, 2000) emphasizes that mathematics teaching programs should emphasize characterization to promote mathematical understanding so that all students: create and use mathematical notions that organize, document, and communicate mathematics; , Develop mathematical representations flexibly and appropriately, and use representations to describe or interpret physical, social, and mathematical phenomena. Thus, the mathematical characterization activities in the students understand and apply the meaning and role of mathematics. Looking at the current math class, although many teachers are aware of the importance of mathematical representation, there is a passive
