This article discusses the conception and development of a digital tool for teaching and learning quadratic functions. The methodological approach is based on Didactic Engineering, encompassing the phases of preliminary and a priori analysis. The theoretical framework articulates the Theory of Didactic Situations (TSD), which guides the organization of teaching situations, and the Theory of Instrumental Genesis (TGI), which allows for the formulation of hypotheses to understand the subject-artifact-instrument process in the appropriation of the tool. The developed application allows for the dynamic manipulation of the coefficients of the quadratic function, with graphical visualization resources, automatic feedback, and interactive activities. The results of the analysis indicate that Didactic Engineering contributes to structuring and validating the pedagogical proposal, while TGI assists in understanding the instrumentation and instrumentalization processes that favor the appropriation of the artifact as a learning tool.
