Summary: The results of an experimental teaching aiming to answer the question: how effective is a didactic mediation of concepts on Riemann integral, using Geogebra software, articulated with usual practices, by students, based on their mobilized and available retrospective knowledge? The goal was to experiment a teaching and learning modes of the Riemann integral of real functions of a real variable, using Geogebra software as instrument, articulated with usual practices. The study was based in Anthropological Theory of the Didactic -- TAD by Chevallard and theory of instrumentation by Rabardel. It was a qualitative study in the form of case study, having appealed to some aspects of didactic engineering: design and a priori analysis of tasks; a posterior analysis and internal validation. The experiment showed that the blended computer and usual practices processes promote construction of knowledge by students to the Riemann integral.
