The case study of the Elementary Education Pedagogy program, practical axis of the University of Atacama, Copiapó, Chile (UDA), sought to generate the theoretical-methodological category Didactic Operation, as a possibility of improvement in the processes given in the practical-procedural dimension of the curriculum. The subjects of the research were seven academics related to professional training processes. The assumption that was handled is that only the curricular problem of the practical-procedural dimension of the curriculum can be approached in its complexity with analytical devices that provide the curricular adaptations of conceptual-theoretical support possible to be mediated by the subject and implemented in the classroom. With this, the presentation is organized in three moments. In the first moment, the context of the program is described, then the category Creative Action in triangulation is alluded to with the information collected from group discussion interviews. It concludes with the field of Didactic Operation. Keywords: creative action, didactic operation, professional practice, didactics.
