国内主流物理化学教材中视觉表征的评价研究——以南京大学主编《物理化学》第六版为例

Evaluation and Research on Visual Representation of Domestic Mainstream Physical Chemistry Textbooks:Taking the Sixth Edition of Physical Chemistry by Nanjing University as an Example

以高等教育出版社2022年出版的南京大学第六版《物理化学》为研究对象,借鉴Gkitzia等人开发的分析框架,运用内容分析法对教材中的视觉表征进行分析。从表征的类型、表征与文本的关联情况、合适的标题和表面特征注释四个维度对教材进行编码分析评价。研究发现:(1)在表征类型方面,存在符号、宏观、微观、多种表征四种形式,但是没有出现多重、多类表征。其中符号表征(72.85%)比例较大,且超过其他几种表征类型的总和,而宏观表征(3.31%)、微观表征(5.63%)明显较少,其中多种表征(18.21%)主要是“宏观-符号”和“微观-符号”的组合。(2)在表征呈现方面,总体质量较高。具体表现为98.34%的视觉表征和文本完全相关并有连接,98.34%的视觉表征有合适的标题,97.68%的视觉表征有清晰的表征注释。最后讨论了研究结果对于物理化学教学的启示。

Taking the sixth edition of Physical Chemistry of Nanjing University published by Higher Education Press in 2022 as the research object,and drawing on the analytical framework developed by Gkitzia et al.,the content analysis method was used to analyze the visual representations in the textbook.Coding statistics and analysis of textbooks are carried out from four dimensions:type of representation,relationship between representation and text,appropriate title and surface feature annotation.The research found that:(1)In terms of representation types,there are symbols,macroscopic,microscopic,and various representations,but there are no multiple or multi-type representations,and the quantity is extremely unbalanced.Amongst,the proportion of symbolic representation(72.85%)is large and exceeds the sum of several other representation forms,while the macro representation(3.31%)and micro representation(5.63%)are significantly less,of which various representations(18.21%)are mainly a combination of“macro-symbol”and“micro-symbol”.(2)In terms of representation presentation,the over-all quality is relatively high,specifically,98.34%of visual representations are completely related and connected to text,98.34%of visual representations have appropriate titles,and 97.68%of visual representations have clear representation annotations.Based on the research results,possible directions for visual representation improvement in physical chemistry textbooks are explored.
