This research presents the results of study on how a collaborative project involving Chemistry teachers can serve as a tool for reflection by the teachers on their conceptions and teaching practices and also to throw some light on deficiencies in the initial training that may not have been remedied in the course of their teaching career. The analysis of each teacher's restructurings was based on their didactic models and on an inventory used to identify these models, so that it was possible to compare them before and after the group's collaborative learning.
