To understand the context of the research, a bibliographic review was carried out about digital educational resources, teacher authorship and digital skills of teachers. The researches have as a methodological approach a case study of qualitative studies, a descriptive and exploratory, and it was adopted the instruments of a survey formed by closed questions and an open question and interviews with teachers. The survey received 712 responses, and 6 teachers were interviewed later. For the analysis, the data triangulation was used, performing a descriptive and inferential statistical treatment for the results of the closed questions and the content analysis with the help of the WebQDA software of the open question and the interviews. The results showed that (i) the types of uses that teachers make of RED can vary according to the pedagogical, didactic and methodological training of the teacher, including RED from content illustration to the development of contextualized educational activities; ii) the teacher s motivation for its uses goes through the belief that the use of RED contributes to the elaboration of more interesting classes, the promotion of new learning opportunities for students and increased motivation to learn, the development of methodological practices and strategies and insertion of the school in the digital culture; (iii) the digital skills developeded by teachers with the use of RED are less complex, within information literacy and focused on pedagogical planning, evaluation developments, and activities and content sharing; (iv) teaching authorship needs to be internalized in the teacher s practice so that he can create more meaningful practices with RED, with no evidence that the use of RED by teachers contributes to the emergence of teaching authorship. It is believed that this study is relevant for contributing to the expansion of discussions about how RED is used by teachers.
