ABSTRACT
This qualitative case study aims to investigate the process of knowledge construction between an in-service teacher and a university professor by focusing on dialogic mediation in reflective sessions, a personal diary, and information from two lesson plans. We draw on teacher education studies from a sociocultural perspective to analyze, in a contextual and situated way, two moments when the in-service teacher changed his teaching practice due to dialogic mediation to which he had access. The analysis of the empirical material allowed us to observe the importance of considering teacher education as distributed across people and tools, besides showing the significance of formal and informal moments in the construction of relevant knowledge for the teacher, especially through strategic mediation and collaborative dialogue.
