Charles TIJUS, Leslie GANET et Patrick BRÉZILLON: Neuf motifs de révision des textes procéduraux: l’apport de la catégorisation contextuelle et des graphes contextuels à l’explication du savoir-faire Know-how is made of knowledge on the actions intervening in the accomplishment of a task. Expressed verbally, this knowledge is itself a task. Studies on problem solving let us to identify, on the one hand, the prerequisite knowledge needed to understand and learn how to accomplish a task, and, on the other hand, the task structure in which the knowledge is embedded. Thus, this approach allows to associate know-how with understanding, learning and with verbal production revision. We point out how two context-based formalism for representing knowledge and reasoning, namely contextual categorization and contextual graphs, can be used for simulating the revision of verbal production of the know-how. The procedural explanation, which can be analyzed in terms of exposition, categorization and implication on the object side to justify the organization of actions in a structure of contextaware goals, is a didactical competence that is not really studied although this competence would help to improve the writing of instructions, and more widely, the teaching of practical knowledge. Thus, we list nine components of the process of revising the verbal production of know-how.
