Por la naturaleza de los conocimientos implicados, la fuerte connotación creativa y heurística, este episodio en particular constituye un referente para impulsar en las aulas saberes metacientíficos relacionados con la construcción, validación y evolución del conocimiento químico. Elementos necesarios para emprender una enseñanza contextualizada del terma en las clases de química, la cual dote de significado y reflexión a su aprendizaje. Este trabajo pretende también, fungir como guía para el análisis histórico y epistemológico de otros contenidos que se develan como relevantes en la educación química.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract: This article presents a historical review of the knowledge, facts, controversies and characters that influenced chemist August Kekulé in order to establish the first accepted chemical characterization of benzene, the structural unit of aromatic compounds. Due to the nature of the knowledge involved, the strong creative and heuristic connotation, this particular episode constitutes a reference to promote meta-scientific knowledge related to the construction, validation and evolution of chemical knowledge in the classroom. These are necessary elements to undertake a contextualized teaching of the topic in chemistry classes, which affords meaning and reflection in the learning. This paper also aims to serve as a guide for historical and epistemological analysis of other contents that are relevant in chemical education.]]></p></abstract>
