"Ciência em Tela" is an open access Brazilian science teacher education online journal that has been published twice a year since 2008 and which encourages the participation of professionals with different backgrounds and the submission of a variety of textual genres, besides research papers. Another feature is that the journal includes practicing schoolteachers not only as authors but also as reviewers, which not only provides those who submit contributions to the journal with an early feedback from their target audience but also helps empower schoolteachers by placing them in a discursive situation in which they are producers, as opposed to consumers, of discourses about science education. In this paper we describe the background to and main aspects of the journal's innovative editorial policy, which seeks to bridge gaps between communities and institutions linked to science education, as well as to discuss the challenges that arise from it, in particular, issues concerning internationalisation and funding, as well as the role of journals in times of colonisation and commodification of knowledge and of discourses.
