我国当前正在使用的各版本的初中数学教科书,在“整式加减”一章的修订中表现出了高度的一致,这既不符合教科书“一标多本”的教材建设体制的初衷,又将教科书的内容设计局限于数学学科思维的羁绊。指向培养学科核心素养的数学教科书的理解,应依托数学学科核心知识,指向数学思维发展过程中所带给学生的文化修养与品格塑造、注意学习情境的主题化与生活化、学习内容的典型性与可迁移性、编排设计的螺旋化等设计策略的运用。
The versions of junior high school mathematics textbooks currently in use in our country show a high degree of agreement in the revision of the chapter “Whole additions and subtractions,” which is neither consistent with the textbook construction system of textbooks The original intention, in turn, limited the content of textbooks to the fetters of mathematical discipline. The understanding of mathematics textbooks that focus on cultivating the core qualifications of a subject should rely on the core knowledge of mathematics and point to the cultural cultivation and character shaping of students brought by the development of mathematical thinking. They should also pay attention to the thematicization and living of learning situations and the typicality of learning contents And the use of such design strategies as mobility, layout design spiral.
