初中数学新旧教材对比分析——以苏科版“图形的变换”为例

Comparative Analysis of New and Old Mathematics Textbooks for Junior High School—Taking “Transformation of Figures” in Jiangsu Phoenix Science and Technology Press as an Example

摘要: 图形的变换是中小学数学课程的核心内容，是培养学生空间观念、几何直观的重要载体。本文以图形的变换为研究对象，从结构编排、概念表述、栏目设置三个维度，比较分析苏科版新旧教材中该内容的变化，发现新教材的修订既契合《义务教育数学课程标准(2022版)》的理念要求，也遵循初中生的认知规律，实现了从“分散知识传授”到“整体素养培育”的转变。基于教材变化，提出了教学策略。

Abstract: Transformation of figures constitutes a core component of mathematics curricula in primary and secondary education, serving as a vital medium for developing students’ spatial awareness and geometric intuition. This study examines the evolution of transformation-related content across the old and new editions of Jiangsu Phoenix Science and Technology Press Mathematics textbooks through three analytical dimensions: structural organization, conceptual articulation, and modular design. The comparative analysis reveals that the revised textbooks not only align with the pedagogical principles outlined in the Compulsory Education Mathematics Curriculum Standards (2022 Edition), but also adhere to cognitive development patterns specific to junior high school students. This marks a significant shift from fragmented knowledge delivery to holistic competency cultivation. Based on these pedagogical advancements, the study proposes targeted instructional strategies to optimize teaching practices.
