Anne-Cécile Mathé

Anne-Cécile Mathé is a Lecturer at the ACTé Laboratory (University of Clermont Auvergne) and a teacher-trainer at INSPE Clermont-Ferrand. Since 2015, she has focused on the didactics of geometry in primary and secondary education, examining the transition between material geometry and theoretical geometry. Her work bridges educational theory with practical classroom challenges.

Education

• 2006: PhD in Mathematics Didactics, Université Claude Bernard, Lyon I
• 2025: HDR (Habilitation à Diriger des Recherches) in Mathematics Education, University of Clermont Auvergne

Research Focus

Mathé explores the continuity of geometry education across French compulsory schooling (ages 6-15), emphasizing:

• Language mediation in geometric knowledge construction
• Didactic situations for semiotic and instrumental transitions
• Teacher gesture modeling in geometric workshops
• Validation and argumentation processes in primary classrooms
• Simulation tools for teacher training (T-Prof simulator)
• Interdisciplinary links between mathematics and physical education

Key Collaborations

• Co-directed research with Marie-Jeanne Perrin-Glorian and Caroline Bulf
• Editorial board member of journals: Spirale-Revue de Recherches en Éducation and Repères-IREM
• Active in COPIRELEM and ARDM associations
