In 1998, at the invitation of Professor Ubiratan D'Ambrosio, Dr. Orey served as a Fulbright Scholar at thePontifícia Universidade Católica de Campinas in Brasil, which he conducted research in classrooms and taught courses in ethnomathematics and mathematical modeling. In 2007, Dr. Orey served as Senior Fulbright Specialist in Kathmandu University, Nepal, giving lectures on topics related to mathematics education and teaching on Ethnomathematics and Modelling. He is currently professor of mathematics education in the Departamento de Educação Matemática and in the Master’ Degree Program in Mathematics Education at the Universidade Federal de Ouro Preto, Brasil.
Pablo Carranza carried out master's and doctorate studies in Mathematics Didactics at Denis Diderot University in France. He has worked as a mathematics teacher in rural, urban, public and private schools. He is currently a research professor at the National University of Rio Negro. There he conducts research on projects in real context as a framework for learning disciplinary concepts. In this context, he directs both research and extension projects aimed at real problems in the community.
