In the case study, a mixed research strategy was used, with the application of an enquiry questionnaire to basic school teachers, as well as interviews to their supervisors. The results show the importance of practical reflectivity and teachers' collaborative work, based on continuous learning. As constraints, supervisors draw attention to a discontinuous reflection, limited to the initial moment of activity planning. On the other hand, teachers point out the problem of being overloaded by school daily tasks and a superficial evaluation of practices, which hinder the deepening of practical reflectivity. http://pubs.sciepub.com/education/3/7/16/education-3-7-16.pdf reflective teacher teacher practices potentialities and constraints case study
