九年级化学教材中化学史内容分析与编写建议

Analysis and Suggestion on Chemical History Contents Compiling in Grade Nine Chemistry Textbooks

通过对4个版本九年级化学教材中化学史内容选取与编排情况的统计和分析，发现随着新课程改革的不断深入，教材中化学史案例数量明显增多，其教育价值已经被广泛认可。虽然教材中关于化学史的内容编排图文并茂，但改进空间依然存在，例如化学家介绍过于简略，介绍角度不够全面；化学发展的描述局限于个别科学家的贡献和孤立的科学事件；化学史学习形式单一、地位不高。为更好地发挥化学史蕴含的教育功能，建议教材中化学家的形象更加丰满，化学研究过程更加完整真实，设计丰富的化学史学习活动，以使学生更加重视化学史的学习，从中受益。

This paper expounded the statistics and analysis of the content selection and ar- rangement of chemical history in four versions of grade nine chemistry textbooks, and found that the number of teaching materials of chemistry history was increasing with the deepening of the new curriculum reform, and their educational value had been widely recognized. Although contents arrangement of chemical history in textbooks were well illustrated, but there still had room for improvement： The introductions of chemists were too simple, and introduction perspectives were not comprehensive enough; the descriptions of chemistry development were confined to the contributions of individual scientists and isolated scientific events; the learning form of chemical history was single. In order to play the educational function of chemical history better, this paper suggested that chemists＇ images should be more plentiful, chemical research processes should be more complete and true, and we should design rich learning activities of chemical history to make students to pay more attention to learning chemical history.
