《数学课程标准》指出,数学教学应源于生活,贴近社会生活,符合学生的发展需要,让学生有所观察、有所体验,以易于理解的现实问题为资源,引领学生在熟悉的情境中理解知识、提高能力。如果数学教学只是简单的符号传递,学生面对现实情境时却束手无策,缺乏解决实际问题的能力。数学教学是开放的、动态的过程,教师要创设教学情境,建立数学与生活世界的联系,让学生运用数学知识去解决现实问题,感受到学习数学知识的价值。
The standard of mathematics curriculum points out that mathematics teaching should come from life and be close to social life in line with the needs of students’ development so that students can observe and experience some of the problems that are easy to understand and lead students in the familiar situations Understand knowledge and improve ability. If the teaching of mathematics is just a simple symbol transfer, students are helpless in the face of real situations and lack the ability to solve practical problems. Mathematics teaching is an open and dynamic process. Teachers should create teaching situations and establish connections between mathematics and the world of life. Students should use mathematics knowledge to solve practical problems and feel the value of learning mathematics knowledge.
