BUENO GARCIA, Seydel  and  PEREZ GONZALEZ, Olga Lidia. Current Practices of the Epistemic and Cognitive Suitability of the Concept of Real Function from a Real Variable in Engineering Careers. Educ. mat. [online]. 2018, vol.30, n.2, pp.202-231.  Epub Feb 07, 2022. ISSN 2448-8089.  https://doi.org/10.24844/em3002.08.

There are inadequacies with the mathematical practices of the meanings of the real functions of a real variable. Then, the methodology of applied didactic analysis shows, with the help of some theoretical tools from the Onto-Semiotic Approach of Knowledge and Mathematical Instruction, a synthesis of the main institutional meanings, which are intentional in the normative documentation (study plans, curricula and textbooks) for the teaching and learning process of the real function concept of a real variable, from its global significance. In addition to this, important improvement criteria to be taken into account for the development of teachers’ work with functions in higher education classrooms are proposed.

Keywords : epistemic suitability; systems of practices; meanings; representation; conversion; function.
