Professional development and collaboration in school: two studies in dialogue

<p>In this paper, after discussing the conceptual positions on professional development and teaching collaboration, we report two studies in the area of language education, in the context of language departments: one, of a more longitudinal nature, aimed at understanding the dynamics of collaborative work in the context of curricular language departments in a region of Portugal; a case study focused on the analysis of a professional development community that aimed to promote collaborative practices based on the development of interdisciplinary projects in the context of the language department of a school. We conclude with the intersection of the two studies and a reflection on possibilities of promoting a professional development in language education based on teacher collaboration in a school context.<strong></strong>
