In this article, some mathematical concepts referring to the quadratic function are investigated, based on the Didactic Engineering research methodology and its French aspects, applying its first two phases. Thus, two didactic teaching situations are elaborated, supported by the teaching methodology, Theory of Didactic Situations, foreseeing the possible behaviors of students before an application. However, a computational resource is then used, available through a simulation at PheT Colorado, with the aim of facilitating the teaching and learning process of students in quadratic functions, contributing to the construction of their own knowledge in the face of these used methodologies. Finally, analyzes are carried out in the face of possible experimentation and validation, in view of possible student behavior, thus contributing to the area of ​​Mathematics Education. It should be noted that the other phases of Didactic Engineering will not be affected.
