Abstract

The concept of substance is considered fundamental in order to understand chemistry and other related concepts, but many problems have been reported about its learning process. Considering the importance of textbooks in the training of chemistry teachers, this study aimed to identify the concepts of substance in general chemistry textbook glossaries. In addition, the study assessed the concepts of substance in relation to other chemical concepts and, when available, compared them with the concepts established by the IUPAC (Compendium of chemical terminology, 2 ed. Blackwell Scientific Publications, Oxford, 1997). The methodology employed was content analysis and the results showed that concepts and statements related to the term ‘substance’ are different in the general chemistry textbooks analyzed. They also differ from those stated by IUPAC. Furthermore, it was found that many concepts are dependent on the concept of substance. It is concluded that there must be a greater effort from the community of chemists and the teaching of chemistry in the search for conceptual uniformity to reduce the problems of conceptual understanding.

普通化学教科书词汇中关于物质概念的差异与概念联系

物质的概念被认为是理解化学和其他相关概念的基础，但是关于它的学习过程有许多问题被报道。考虑到教材在化学教师培训中的重要性，本研究旨在识别普通化学教材词汇中的物质概念。此外，该研究评估了物质概念与其他化学概念的关系，并在可用的情况下，将它们与IUPAC建立的概念进行了比较(化学术语汇编，2版。Blackwell科学出版物，牛津，1997年)。所采用的方法是内容分析，结果表明，与“物质”一词相关的概念和陈述在所分析的普通化学教科书中有所不同。它们也与IUPAC声明的不同。此外，还发现许多概念都依赖于实体概念。结论是，化学学界和化学教学必须作出更大的努力，寻求概念的统一性，以减少概念理解的问题。

期刊介绍： Foundations of Chemistry is an international journal which seeks to provide an interdisciplinary forum where chemists, biochemists, philosophers, historians, educators and sociologists with an interest in foundational issues can discuss conceptual and fundamental issues which relate to the `central science'' of chemistry. Such issues include the autonomous role of chemistry between physics and biology and the question of the reduction of chemistry to quantum mechanics. The journal will publish peer-reviewed academic articles on a wide range of subdisciplines, among others: chemical models, chemical language, metaphors, and theoretical terms; chemical evolution and artificial self-replication; industrial application, environmental concern, and the social and ethical aspects of chemistry''s professionalism; the nature of modeling and the role of instrumentation in chemistry; institutional studies and the nature of explanation in the chemical sciences; theoretical chemistry, molecular structure and chaos; the issue of realism; molecular biology, bio-inorganic chemistry; historical studies on ancient chemistry, medieval chemistry and alchemy; philosophical and historical articles; and material of a didactic nature relating to all topics in the chemical sciences. Foundations of Chemistry plans to feature special issues devoted to particular themes, and will contain book reviews and discussion notes. Audience: chemists, biochemists, philosophers, historians, chemical educators, sociologists, and other scientists with an interest in the foundational issues of science.
