Abstract

The article addresses the investigation of validation in mathematical modelling activities. For research interests in outlining a framework for validation in these activities, data triangulation is used as an alternative to provide coherence and cohesion to what is intended to be done. For the organization of the framework, a theoretical framework regarding the theme is captured. In addition, an empirical research is carried out with students of a Mathematics Degree course. The gathering of empirical data and the theoretical structure allows characterizing understandings, the importance and ways of carrying out validation in mathematical modelling. Although it can be recognized as the final step in the modelling cycles, validation cannot be thought of as a cumulative process that only begins at the end of the activity and from which only acceptance or refutation results. Instead, it can act as an iterative agent and guide students' decision-making processes, and validation mechanisms can be activated at different stages of the activity. What can be concluded, therefore, is that, even if specific actions are recognized, it is in the validation of the totality of the modelling that the efficiency of validation resides as a means of generating reliability in what can be said about a situation of reality by using mathematics.
