ab: 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.
