This presentation describes the development of an e-textbook for first-year Portuguese classes. This pedagogical initiative strives to provide an inclusionary and open textbook for Portuguese, including the collaboration and feedback from Portuguese speakers of several economic and cultural backgrounds. In this context, “openness” means listening to the language of a given community and the commitment to reproduce it in a textbook format. Inclusion of minority groups in the textbook is perceived not as “curiosities,” but as an integral part of the cultures being represented so that a wider range of communities and language registers (from formal to informal) is portrayed. While the example presented here is in Portuguese, the process of developing open and inclusionary language materials applies to all languages.
