Model for retranscribing and analysing the mathematical activity of subjects in problem solving
Résumé
In this paper we present a model for tracking the activity traces of individuals placed in autonomous
problem solving. In order to collect as many traces as possible, we use a collection method based on audiovisual recordings. This model is presented in three steps. The first step concerns the choice of observables: typology and choice of elementary actions and possible strategies. A second one at the level of the processing of the corpus of data in connection with the retranscription and its summaries. This second step is devoid of interpretation, it is in fact completely deterministic and allows the replay of each of the actions performed by the subjects. The third and final step consists in analyzing this retranscription by identifying sequences of actions that are similar or close to the strategies identified.
