Mon implication dans l’enseignement concerne la formation à l’outil ARIANE, plusieurs fois par an, pour des chercheurs individuels ou des groupes, avec le programme type suivant : accueil au LOPS, démarche d’analyse, fonctionnalités de l’outil, concepts numériques, mise en application (avec Nicolas GRIMA, ingénieur de recherche au CNRS), interprétation de premiers résultats. Cette formation dispose désormais d’un ensemble de vidéos, grâce à une interaction avec le service audiovisuel de l’UBO.
