摘　　要：化学教科书作为教学内容的重要载体,其中涉及各种反映微观过程的视觉表征。视觉表征凭借其直观、形象、可视的特点能够促进学生充分理解化学概念,因此其准确性与适切性直接影响学生的学习。电离是高中化学内容中的核心概念,其较为抽象且难理解,学生在学习该内容时往往存在相异构想。在调查学生对氯化钠电离的相关认识基础上,分析不同时期、不同版本国内外初高中化学教科书中氯化钠水溶液电离的视觉表征,对其进行横向和纵向比较研究,并结合有关最新科技成果,力图为我国中学化学教科书的后续编写提供一定参考。As an important carrier of teaching content,chemistry textbooks involve various visual representations reflecting microscopic processes.Visual representation,with its intuitive,vivid and visual characteristics,can promote students to fully understand chemical concepts,so its accuracy and relevance directly affect students'learning.Ionization is the core concept in high school chemistry content,which is abstract and difficult to understand,and students often have heterogeneous thoughts when learning this content.Based on the investigation of students' understanding of sodium chloride ionization,the visual representation of sodium chloride solution ionization in junior and senior high school chemistry textbooks at home and abroad in different periods and versions is analyzed,and the horizontal and vertical comparative study is carried out,combined with the latest scientific and technological achievements,in an effort to provide some reference for the subsequent compilation of Chinese middle school chemistry textbooks.
