This article presents an investigation regarding the semiotic resources activated in mathematical modeling activities and their role in the development of these activities when this takes place in an online context. The theoretical framework of the research includes Mathematical Modeling in Mathematics Education and Semiotics as a science of signs. An empirical research is developed with students of a postgraduate studies in the area of Mathematics Education. The analysis follows the assumptions of a qualitative research, particularly a case study. The results indicate that the online development of the activity gives rise to a semiotic system that is rarely mentioned in research: the technological system. The resources enabled in this system are combined and interrelated and have the semiotic potential of allowing students to visualize, test and examine their approaches to the problem situation explored by the mathematical modeling activity.
