The following paper is the product of a study that inscribes itself in the universe of the material school culture, having as methodology the bibliographical method, aiming to highlight the history of a technical material support that is relevant for the practices of the modern school: the scholar slate. We concentrate in the time and space given by the nineteenth century, since it is the scene that will give visibility to the effort of diffusion of the first school practices of teaching. We start from the hypothesis that the relation between material and method can translate teaching conceptions, conferring centrality to the slate as the technology that, when inscribed in the set of school practices, will result in the constitution and consolidation of the scholar model of simultaneous transmission of education.
