This thesis entitled "Learning Mathematical Modelling the interactions of the elements of an activity system from the perspective of the Engeström activity theory" aimed at understanding effects on learning by interactions evidenced in Mathematical Modeling environment, from the perspective of Engeström activity theory. To accomplish this, I developed in the Mathematical Modeling Experimental Laboratory (LEMM), at the University Campus of Castanhal (UFPA), modeling activities with groups of Math Course students in graduating, graduate or post graduate students to obtain data through observation and interview. Based on the principles of the Engeström activity theory, Mathematical Modeling developed by the students were understood as an activity system that involves the elements (subject, object and community artifacts mediators, rules and division of labor) that relate to a result, that are mediated by interactions for achieving a result. Research has shown that the collective work, the historicity and multivocality of subjects acting in overcoming contradictions to reach expansive transformations have repercussions on learning in Mathematical Modeling, configured as an activity system, the interactions of the elements of the system itself.

Cooperação no desenvolvimento de atividades de modelagem na educação matemática

This article is a cut of a master's thesis that sought to identify and analyze implications arising from the use of Digital Technologies in the development of Mathematical Modeling activities. In this section, we aim to analyze the cooperation between subjects (students and teacher) and digital technologies in the development of Mathematical Modeling activities. The research is of the qualitative type, in which powerpoint reports and presentations produced by students of the math course and audio and video recordings recorded by the mediating teacher in the development of three activities of Mathematical Modeling were analyzed. In this way, it was possible to describe the cooperation established between the mediating teacher, the students and the digital technologies, allowing us to infer that this triad set up a semantic network (complex cognitive mixes and cooperatives) around the themes investigated.
