Martins, Marina; Justi, Rosária – International Journal of Science Education, 2019
The aims of this paper are twofold. First, we present, justify, and characterise an instrument for analysing students' argumentative reasoning developed from Walton's ideas. Then, from the analysis of students' argumentative discussion about a socio-scientific controversy, we identify the advantages and disadvantages of using the instrument. The…

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…

This study investigates to what extent a context of explicit…
