摘要:DOI: http://dx.doi.org/10.14244/19827199890 Based on the experiences in a course on Science, Technology and Society (STS), we verified that it is high time to articulate academic discussions with the school environment if we want to promote critical and transformative education. Generally, this issue is considered only for the endless research projects and is rarely discussed in the classroom for effective implementation with students. With this concern, some activities in this discipline demonstrated the strong potential of some documentary videos as educational tools to promote the urgent debate on STS issues. In this article, we seek to broaden the discussion of how STS can provide perspective to education, a critical and emancipatory possibility. But in order to do so, strong instruments compatible with the new availability of modern media are required. This could cope - unfortunately, still in a small proportion - with the apparatuses of hegemonic power that uses this resource as a tool of deception and alienation. Keywords: Educational practices, Critical education, Documentary videos, STS.
