从知识架构视角对比七年级新旧教材的变化——以“代数式”为例

Comparing the Changes of the Old and New Textbooks in the Seventh Grade from the Perspective of Knowledge Structure—Taking “Algebraic Equations” as an Example

摘要: 数学教材的更新反映了教育理念与教育需求的时代变迁。采用比较研究法，从知识架构的视角深入对比七年级新旧教材“代数式”的变化及意义。通过对章节结构、内容变化与删减及例习题设置方面进行对比分析，揭示新教材在知识结构上的优化和发展，有利于推动课程改革的深入和教学策略的优化。基于研究结果提出三点建议：重视知识之间的自然转换和有效联结；对例习题背景进行更新优化；推动例习题的多元化发展。

Abstract: The updating of math textbooks reflects the changing concepts and needs of education. The comparative study method is adopted to compare the changes and significance of “Algebraic Formulas” in the new and old textbooks of Grade 7 from the perspective of knowledge structure. The comparative analysis of chapter structure, content changes and deletions, and examples and exercises, reveals the optimization and development of the new textbook in terms of knowledge structure, which is conducive to promoting curriculum reform and optimizing teaching strategies. Based on the results of the study, three suggestions are made: to emphasize the natural transformation and effective connection between knowledge, to update and optimize the background of the sample problems, and to promote the diversified development of the sample problems.
