Prof. Susana Carreira

University of Lisbon, Portugal

Susana Carreira received her Ph.D. in mathematics education from the University of Lisbon. She is Associate Professor at the Faculty of Sciences and Technology of the University of Algarve, where she has been teaching mathematics courses to undergraduates in science, engineering, and management, as well as mathematics education courses to prospective secondary mathematics teachers, and to master students in mathematics education. For several years she has collaborated with the Institute of Education of the University of Lisbon, as Invited Associate Professor, where she contributes to doctoral seminars and supervises PhD students in mathematics education. Susana Carreira has also been participating in the Postgraduate Program in Teaching of the University of Vale do Taquari – UNIVATES, in Brazil, where she teaches courses on mathematics education and research methods, as well as supervises master and doctoral dissertations.

As a mathematics education researcher, she is a member of UIDEF, the research centre in education based at the Institute of Education, in Lisbon. Her research interests and activities have spanned across different domains in mathematics education. Since her master’s degree, when she investigated secondary students’ use of the spreadsheet in solving applied problems, her work on digital technologies in mathematics education has continued, both in relation to mathematical problem solving and to mathematical modelling. For more than a decade, she was involved in organizing and running inclusive web-based problem-solving competitions, in the south of Portugal, targeting students from grades 5 to 9. This extended activity was at the origin of the research project Problem@Web, where she was the leading investigator. It also fuelled some other lines of her work, namely mathematical creativity, attitudes, and emotions in mathematical problem solving, and the nature of techno-mathematical fluency.

Much of her research over the years has focused on the teaching and learning of mathematical modelling. Her PhD thesis addressed the production of meaning by undergraduate students in solving modelling problems, considering the relationship between models and conceptual metaphors. Her work has been addressing different aspects of students’ modelling processes, such as the cognitive processes involved in modelling problems or the influence of experimental work on students’ modelling thinking. More recently, she has been interested in integrated STEM education, specifically in the context of interdisciplinary projects and vocational education, in close connection to her work on mathematical modelling.

Susana Carreira has been part of the ICTMA Community for several years and served has Elected Member of the International Executive Committee. She has attended and participated in many of the ICTMA conferences and was a member of the local organizing committee of the ICTMA-9 held in Lisbon, in 1999. From 2009 to the present, she has been actively involved in the CERME conferences as leader or co-leader of the Thematic Working Group on applications and modelling. She was also co-chair of the Topic Study Group on mathematical modelling and applications at ICME 11 and ICME 14.
