Uwe Gellert Editor

Dr. Gilles Aldon is a mathematics teacher and researcher at the Ecole Normale Supérieure de Lyon. He is particularly involved in research on problem solving linked with the integration of new technologies in the classroom. His Phd focuses on the use of technology in the regular classroom of mathematics, seeking to understand how the incidents are indicative of perturbations that change the dynamic of the class. His research focuses:

- on the links between problem solving and the actual use of technology in the classroom,

- on the possibilities of multi-representations given by technology and the links with teaching and learning,

- on the role of technology in assessment and particularly formative assessment.

Fernando Hitt is a Professor of Mathematics Education in the mathematics department of the Faculty of Sciences at the Université du Québec à Montréal, Québec, Canada. His research interests are related to the notion of epistemological obstacles in the learning of mathematics and the use of technology in mathematics education.  He is currently a member of the Commission Internationale pour l’Étude et l’Amélioration de l’Enseignement des Mathématiques (CIEAEM).

Luciana Bazzini is professor emeritus of Mathematics Education at the University of Torino (Italy). Since the Seventies she has been doing research in Algebraic Thinking, Curriculum development in primary education and Teacher training, with the main purpose of bridging theoretical issues and school practice. She published books and papers on scientific journals and played active role in many international conferences. She acted as Secretary of CIEAEM (1998-2003) and Vice President (since 2013).
