The purpose of this paper is to investigate lecturers'actions and conceptions about pre-service teaching practices in chemistry. In this sense, it takes into account several theoretical references concerned with teacher education, which support the qualitative analysis of 18 interviews, gathered with 14 brazilian and 4 portuguese lecturers. Results reveal that the pre-service teaching practices in chemistry have been performed far from a technical approach, showing a paradigmatic rupture and presenting another logic related with teacher education in chemistry, which have improved the comprehension of the teachers' real practices, since these have been shaped by complex and unprescribed factors.
