      The purpose of the research is to account for the geometric learning produced in a simulator creation experience with GeoGebra in Secondary School, in Venezuela. For this, we rely on the objectification process category, developed in the Theory of Objectivation, in order to describe and interpret this learning from the way in which a mathematic teacher and two Secondary School students become aware of the idea of rotation embodied in the tools of software construction. Through a multisemiotic analysis of activity, the various semiotic recourses (signs and artefacts) put into play by the participants are examined in an integrated and systematic way, paying attention to their dialectical and dynamic relations. Participants draw on these resources to reach a relatively stable level of consciousness about the conceptualization of the rotation mobilized in the construction of a circle. In the conclusions, some aspects of reported objectification processes are discussed, such as the semiotic activity displayed, the teacher’s performance and the difficulties arising in that activity.
      O propósito da pesquisa é dar conta da aprendizagem geométrica produzida em uma experiência de elaboração de simuladores com o GeoGebra no Ensino Médio, na Venezuela. Para tal, apoiamo-nos na categoria processos de objetivação, desenvolvida na Teoria da Objetivação, com o intuito de descrever e interpretar essa aprendizagem no que diz respeito à maneira em que um professor de matemática e dois alunos do Ensino Médio tomam consciência da ideia da rotação nas ferramentas de construção do software. Através de uma análise multisemiótica da atividade, examinam-se de forma integrada e sistémica os distintos meios semióticos (signos e artefatos) postos em jogo pelos participantes para alcançar um nível de consciência relativamente estável sobre a conceitualidade da rotação mobilizada na construção de um círculo, atendendo às relações dialéticas e dinâmicas entre esses meios. Nas conclusões discutem-se alguns aspectos dos processos de objetivação reportados, como a atividade semiótica desenvolvida, a atuação do professor e as dificuldades surgidas nessa atividade
