"Only one of Freire’s (1969/1983) books directly and more broadly addresses the scope of communication; it is 'Extension or Communication?' published in 1969, originally in Spanish, during Freire’s exile in Chile. This book became an important reference for the studies and practices of participa ... tory communication worldwide and was decisive for the review of diffusion models, which took communication as a tool to guide the reproduction of models considered modern and developed, without paying attention to local experiences and knowledge. Approached more broadly, the transversality of communication in Freire’s pedagogical perspective can be discussed from at least three perspectives. The first combines language, education and communication. The second links education and communication with popular mobilization and, more openly, with processes of political engagement. The third stems from Freire’s own critical positioning in relation to the media. These three inflections will be discussed in more detail throughout the material compiled in this edition of MATRIZes." (Introduction, page 5) more
