Abstract

The aim is to characterize competencies and skills of high school students through the case method. This proposal evidences the need to develop competences and skills that allow the transition from the educational environment to the work environment. Following Maaß’s modeling perspective, the productions of a group of two 16-year-old students are analyzed, when approaching 3D geometric mode-ling with projections for the work environment, considering a STEM support. The results indicate that the students expressed mathematical, scientific, technological and engineering competences, related to the current demands of the 21st century, through the case method, obtaining a solution proposal according to their work training profile. It is also shown that students, when modeling in 3D, go through all the proposed phases of modeling mathematical competences. Finally, it should be noted that 3D modeling promoted the development of technological and ma-thematical modeling skills of the students and enhanced the solution of the case.
