This thesis has as main objective proposes a conceptual model to represent and treat body signals such as facial expressions, heartbeat and brain waves, in the learning process. For this, three experiments were carried out in educational institutions in the city of Santarém. In Early Childhood Education and Elementary School 1, which are part of Basic Education, the participants were teachers at Colégio Dom Amando - CDA. In Technical Education, the participants were students of the Computer Maintenance discipline of the Technical Course in Informatics at the Centro de Formação Jessé Pinto Freire - SENAC and, in Higher Education, students enrolled in the discipline of Information and Communication Technology linked to the Science course in Computing at the Universidade Federal do Oeste do Pará - UFOPA. The experiments were guided by a seven-step process, supported by technological tools such as the CADAP platform, Heart Rate Sensor, Oximeter and Emotiv Epoc +. The research was qualitative and quantitative, the methodology used was action research, involving planning, action, description and analysis steps in all experiments. Regarding the results, they showed that the emotional state of the participants during the performance of the different types of activities could be perceived through the monitoring of body signals, thus validating the hypotheses raised in this research. The model and the experiments were evaluated by all participants, obtaining a positive feedback regarding their applied in learning spaces, aiming at the possibility of improvements in the learning and teaching processes. It is concluded that, analyzing the data set on heartbeat, performance metrics through brain waves and emotional states by facial expressions, the same activity can produce different reactions in the participants, according to the methodology used by the teacher, the which reaffirmed the premise that learning should always be student-centered. Future research will be conducted to expand the number of experiments, in several areas, also addressing the public of teachers, in order to compare the data and point out potential improvements to the methodological process applied.
