Implementation of the new multidisciplinary gradual model for the development of a didactic sequence under Blum’s modeling cycle approach in descriptive statistics

The elaboration of didactic sequences based on a pedagogical-tecnological theoretical foundation makes it possible to enrich the quality of teaching proposals and didactic resources. This paper presents an adaptation of the Multidisciplinary Gradual Model [1] that incorporates Blum’s modeling cycle [2] for the elaboration of an educational resource that is embedded in a didactic sequence. The usefulness of the proposed model is the feasibility of implementing different development technologies and different positions in the pedagogical aspect, which allows the creators to diversify of resources. A case study is presented for the didactic sequence “Measures of central tendency” in a third year group of a technological career
