This article aims to understand the process of meaning construction demonstrated in the “Tarsila Book Factory” project, a initiative by Professor Luis Mario, aimed at integrating teaching-learning processes and digital information and communication technologies . This is a pedagogical action in which members of the school community are encouraged to produce their own books. The stages of this process encompass writing, drawing, organizing the produced material, binding, and dissemination. “Body and Soul in Poems” by Kawanny Bezerra de Freitas, a ninth-grade student, written in 2018, is one of the various specimens that this researcher had the privilege of knowing and analyzing. However, the choice of this work occurred after reading the last lines written by the teacher regarding the student, which resonate with my thoughts and feelings: “... she brings us a little of her reading and life experiences through the power of her words!” (p.14). As a methodological resource, C.S. Peirce’s semiotic theory will be used, emphasizing its phenomenological categories to better understand the communicative semiosis that the sign ‘author’s book’ generates from this experience (PEIRCE, 1977; SANTAELLA 2006,2010,2017,2021; CHIACHIRI,2010). The partial results of this study suggest that the author’s book is not merely a collection of words and images. The communicative potential it acquires is a possibility of interaction between the student-author’s experience and that of this researcher, who was drawn into the book. There are two people in the communication constructing meanings. It is not the commercial product book, but the semiotic device of social belonging.
