QUIROGA, Nicolás Baudino  and  COLEONI, Enrique A.. Refinando el principio de Arquímides mediante la experimentación en clase, un análisis desde la progresividad del discurso. Rev. enseñ. fís. [online]. 2021, vol.33, suppl.1, pp.9-9. ISSN 0326-7091.

A case study of a real class is presented during which students analyze the situation of a container of water, located on the pan of a balance. They are asked if (and how) the scale reading will be altered by placing a floating wooden body in the water. The research question is what role the experiment occupies in the social mechanism of progressivity. The analysis shows that the experiment can strongly influence the discursive dynamics in the classroom. In the case analyzed, it operates as an element that fixes a part of the semantic structure. The study enriches the understanding of interactions in the classroom and how they could be fostered; at the same time, it provides information about how to generate the conditions for an experiment to be relevant from the point of view of learning concepts and can be interpreted in depth by students.

Keywords : Experiment; Discourse progressiveness; Real classroom.
