新《数学课程标准》明确指出,数学教学要紧密联系学生的生活情境,从学生的生活经验和已有知识出发,使学生初步感受数学与日常生活的密切联系。数学是人们生活、劳动和学习必不可少的工具。新的课程标准对数学教学提出了新的目标,那就是:人人应该学有价值的数学,都能获得必需的数学;不同的人在数学上得到不同的发展,这其中“交流”对数学教学起到了非常重要的作用。交流能沟通人与人之间的情感,交流能做到优势互补,交流能博采众长。
The new “Mathematics Curriculum Standards” clearly points out that mathematics teaching should closely link with students’ life situations. Starting from students’ life experience and existing knowledge, students should initially feel the close relationship between mathematics and daily life. Mathematics is an indispensable tool for people to live, work and learn. The new curriculum standard sets a new goal for mathematics teaching. That is: Everyone should learn valuable mathematics and get necessary mathematics; different people get different developments in mathematics. Among them, “exchange” is a matter of mathematics. Teaching plays a very important role. Communication can communicate the emotions between people, and exchanges can complement each other, and exchanges can attract others.
