This article discusses the results of a research on the process of formation of Chemistry teachers who work in YOUTH AND ADULT EDUCATION (YAE) at public schools in the state of Paraná, Brazil, organized based on Freire's theoretical and methodological assumptions. Data collection took place in a university extension course in which the participants discussed, organized and developed Chemistry classes. The analytical assumptions of the research make reference in the "critical analysis" on the teaching practices in Freire's perspective and epistemology of Ludwik Fleck. In this course, possible styles of thought that the collective of teachers had on the social role of Chemistry teaching and how this should occur in the YAE were discussed. Some of the common problems for teacher training as well as for Freirean continuing education were identified.
