What Is A Chemical Element?
In the present work, the notion of chemical element is analyzed from the perspective of chemical education. Chemists refer to elements either as the final term of chemical analysis (i.e., simple substances) or as what persists in a chemical change. T

RiassuntoDopo una riflessione sulla differenza tra sapere, conoscenza e informazione e sull’equilibrio dei rapporti tra insegnante, allievo e sapere, che una didattica efficace deve garantire, questo lavoro affronta il problema della trasposizione

Notre contribution consiste en une analyse semio-epistemologique du processus de la modelisation de la matiere et de ses transformations, notamment pendant la periode fin XVIIIe-debut XIXe siecles. Nous mobilisons la theorie semiotique de Peirce comm

A novel didactic sequence is proposed for the teaching of chemical equilibrium. This teaching sequence takes into account the historical and epistemological evolution of the concept, the alternative conceptions and learning difficulties highlighted b

Riassunto Le reazioni di ossidoriduzione costituiscono un argomento centrale di qualsiasi corso di base di chimica, sia a livello scolastico che universitario. Il loro apprendimento comporta il superamento di svariati ostacoli concettuali, la cui dif

A didactic sequence is proposed for the teaching of chemical equilibrium law. In this approach, we have avoided the kinetic derivation and the thermodynamic justification of the equilibrium constant. The equilibrium constant expression is established

Throughout the centuries, the concept of element has undergone a clear evolution from a strictly philosophical area to the scientific domain, although the conceptual progress has not always gone along with a terminological evolution. Some inconsisten

This article presents and illustrates a proposed application of concept maps in chemistry teaching in high schools. The students were provided with the "concept lables" necessary for map building in three different ways. The analysis of the students'
