Abstract: In this research, it was propose to investigate the conceptual elaborations produced by students of a ninth grade class of a college in the city of Lavras – MG (Brazil). With this in mind, the field of Trigonometry concepts was introduce through Learning Situations (SDA) mediated by digital technologies in a logical-historical perspective. In this bias, the general objective was to analyze the development of theoretical thinking in the field of Trigonometry concepts from the processes of signification produced. In short, to develop the activity, it was investigated the possible conceptual links of Trigonometry, considering that the content is a field of concepts that, at a given moment in history, were developed by logical and social needs. Therefore, from the audiovisual media records and field diary, one episode was identified, four cores of signification produced throughout the scenes. Thus, since the SDA created an evident Zone of Imminent Development and the participants had an evolution from empirical thought to theoretical thought, always encompassing the concepts with the historical question that constituted them.
