This article aims to demonstrate, through the theoretical and methodological assumptions of the social-historical approach in Psychology and those of the contemporary French ergonomic tradition, how it is possible to subsidize a teacher formation that does not promote a dichotomy between knowledge and action, improving, consequently, the quality of schooling. The main categories and concepts employed are explicated as well as the procedures used to collect data from a second grade teacher, working in a public institution located in Sao Paulo city, Brazil. Finally, a description and an interpretation of the collected data are presented, showing how initial and/or continuous teacher formation can be enriched by the type of analysis that was conducted.
