RESUMO:

This dissertation aimed to identify the potential of GeoGebra to learn the conceptual aspects involved in the study of the Quadratic Function. The pedagogical intervention occurred in an EJA class at CIEP 055 João Gregório Galindo, located in Angra dos Reis (RJ). The innovation was carried out in the teaching practice itself and is inserted in a context in which the students did not have the opportunity to follow the studies in a regular way, with age and indicated series. As forms of data collection were used: teacher-researcher field diaries, responses to activities, screen capture, video recording, photographic records. The activities were elaborated to explore and analyze relations between coefficients, discriminant, roots and vertex of the parabola. The theoretical basis was based on the instrumental approach of Rabardel, particularly in the elucidation of relations between the four poles (subjects, object, instrument and other subjects) of the model of the situations of instrumental collective activities. The preliminary analysis indicates that instrumental genesis may be an adequate tool to study the cognitive process of the quadratic function, since it has developed new use schemes that allowed it to solve the proposed situations.
