This article analyzes the relationship between pupils' level of understanding of the analogies proposed in class while working with a model of chemical change and their competence at constructing a coherent verbal discourse of that model in both its macroscopic and submicroscopic representations. The study participants were 35 pupils in their 3rd year of compulsory secondary education (14-15 years of age) who had been studying chemical change for several weeks in their subject of Physics and Chemistry. The results suggested that the pupils generally understood the proposed analogies quite well, and that a good proportion of them assimilated adequately the verbal discourse inherent in the proposed model of chemical change. There was also a statistically significant association between modeling and analogical thinking. In particular, the pupils with greater understanding of the analogies being considered were also those who tended to show a greater ability to verbalize the model of chemical change and reason with it when solving the tasks they had been set. These results concur with the literature by suggesting that a link exists between analogical thinking and modeling, and that learning with analogies has a positive influence on the construction of the chemical change model.
