Studies on policy and on activities of social appropriation of science and technology (SAST) in Colombia have shown the presence of a deficit model that characterizes the relationship between scientific knowledge and the public. This model, which is present in diverse communicative and educational activities, is characterized by establishing unidirectional and vertical communication dynamics from science to its public. However, these studies have fallen short in identifying what the production conditions that sustain this model are. Analyzing the case of an educational booklet, this article seeks to deepen the understanding of what it is that defines the SAST practice in Colombia as deficitarian. This was achieved through an ethnographic content analysis of educational material, which allowed the identification of a number of language and graphic devices that, in the future, could become a reflexive guide in the design of new educational and communicative materials for the SAST.
