Abstract

In the chemical education field, the Johnstone’s triangle represents three learning levels (symbolic, macroscopic, and molecular) needed for students. Afterwards, Mahaffy suggested a tetrahedron model based on this triangle, where the top represents the human element. Subsequently, Sjöström proposed a subdivision of the top into three other levels: applied chemistry, socio-cultural context, and critical–philosophic approach. These six dimensions of chemical knowledge will be examined in relation to the discovery of aniline, its chemistry and applications. The historical and epistemic aspects of this topic, gradually broadening the focus to the social, political, and artistic backdrop, can provide a more effective approach to teaching the subject. The major impact of the synthetic dye industry makes this field of study particularly important for a Bildung-focused chemistry education.
