The research was developed through a case study and to develop the research we carried out a training course so that undergraduates could learn about and use the platform to develop the applications proposed in the course. To do this, we use Rabardel's theory, based on the authors Júnior and Nunes (2015) who explain the processes of instrumental genesis that consist of instrumentation and instrumentalization activities. Based on observations during the course, we noticed that the undergraduates were not familiar with the Mit App Inventor 2 platform, with their first contact occurring during the course. After completing each stage of the course, students took ownership of the platform's properties, enhancing their knowledge according to the instrumental activity situation model – SAI, transforming the artifact into an instrument.Attribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/SAI-Teoria de rabardelPlataforma App InventorPrática de ensinoDissertaçãoCNPQ::CIENCIAS EXATAS E DA TERRA::MATEMATICAEDUCAÇÃO MATEMÁTICA
