Santini, Jérome; Sensevy, Gérard; Quilio, Serge; Forest, Dominique; Blocher, Jean-Noël – International Journal of Science Education, 2022
This paper addresses the subject of the semiosis process in the transactions between teachers and students about the knowledge at stake in science education. We present a conceptualisation of these transactions as a joint action between students and teachers. This conceptualisation enables us to understand the semiosis process as it unfolds during…

Blanco-Anaya, Paloma; Justi, Rosária; Díaz de Bustamante, Joaquín – International Journal of Science Education, 2017
Modelling-based teaching activities have been designed and analysed from distinct theoretical perspectives. In this paper, we use one of them--the model of modelling diagram (MMD)--as an analytical tool in a regular classroom context. This paper examines the challenges that arise when the MMD is used as an analytical tool to characterise the…
