摘　　要：“长度单位”是几何测量的基本单位,也是日常生活中常用的计量单位,一直是小学数学的传统教学内容.新中国成立以来,小学数学教材中“长度单位”内容的结构体系、知识容量、呈现方式等都发生了很大变化.对此,选择人教版不同阶段的4套教材进行内容分析、概括特点,得到如下启示:教材内容的选择应依据计量制度的改革和学生的实际需要;教材内容的呈现应重视知识产生,体现“过程性”;教材中插图应力求承载丰富的数学信息,发挥“思想材料”的功能;教材编写设计应由基于“教”走向关注“学”,利于学生数学素养的发展.“Length Unit”is the basic unit of geometric measurement and is also a commonly used measurement unit in daily life.It has always been the traditional teaching content of primary school mathematics.Since the founding of the country,great changes have taken place in the structural system,knowledge capacity,and presentation mode of the“Length Unit”content in primary school mathematics textbooks.We selected four sets of textbooks at different stages of the People’s Education Press for content analysis and summary characteristics,with the following findings:The selection of textbook content should be based on the reform of the measurement system and the actual needs of students;the presentation of textbook content should attach importance to knowledge generation and reflect the“process”;the illustrations in the textbook should strive to carry rich mathematical information and serve the function of“ideological materials”;and the compilation and design of textbooks should shift from being based on“teaching”to focusing on“learning,”which is conducive to the development of students’mathematical literacy.
