About the Journal

Tangram is a quarterly scientific journal which publishes papers about different aspects related to the field of Mathematics Education. The journal resulted from the interaction between two Federal University of Grande Dourados (UFGD) research groups linked to the Faculty of Exact Sciences and Technology (FACET), the Faculty of Education (FAED), and the Faculty of Indigenous Intercultural Education (FAIND): one called “Network of Mathematics Education Researches – TeiaMat/CNPq” and, the other, “Technologies of Mathematics Education Research Group – GPTEM/CNPq”.
Tangram aims to diffuse results generated from scientific researches, theoretical studies, scientific initiation assignments and notes on pedagogical experiences from primary to higher education. The journal focuses on papers about Mathematics Education and similar areas of study, which can be presented in Portuguese, Spanish and English. Besides the periodic issues, Tangram publishes a thematic edition once a year under the coordination of internal and external members of its team.
