WG1: Argumentation and proof
4-8 February 2015, Prague, Czech Republic

The 9^th Congress of Europen Research in Mathematics Education will take place in Prague at the Faculty of Education, Charles University in Prague. The Working Group 1, Argumentation and Proof, offers a stimulating forum for researchers interested in this field.

Leaders

Samuele Antonini (Italy) - Orly Buchbinder (United States), Kirsten Pfeiffer (Ireland) — Gabriel Stylianides (United Kingdom)

Scope and Focus of WG1

The role and importance assigned to argumentation and proof in the last decades has led to an enormous variety of approaches to research in this area. Papers presented in the last ERME Conferences illustrate this diversity, offering a wide spectrum of perspectives, intertwining educational issues with explicit references to mathematical, logical, historical, philosophical, epistemological, psychological, curricular, anthropological and sociological issues. The scope of the working group is offering the participants the richness of diversity and the opportunity of a fruitful discussion, stimulating not only the interest of comparison but also the curiosity of undertaking a possible integration and the need of enhancing the development of international collaborations.
