ETM Meetings are organized into working groups based on the contributions proposed by participants. The form of the Symposium allows an interesting exchange of ideas amongst participants and encourages the development of a scientific community with common interests. ETM meetings have an international dimension (Argentina, Canada, Chile, Cyprus, France, Greece, Mexico, Spain, etc.) and a multilingual participation (English, Spanish, French).

The first ETM meeting took place in October 24-25, 2009 in Nicosia (Cyprus).
Communications of this first meeting were published in the book: Gagatsis, A., Kuzniak, A., Deliyianni, E., & Vivier, L. (eds, 2009). Cyprus and France, Research in Mathematics Education, Lefkosia.

The second meeting was held in October 22-23, 2010 in Paris, for the first time in the form of a symposium. The papers presented in this symposium were published after being reviewed in the journal Annales de Didactique et de Sciences Cognitives. (Vol. 16 and 17, http://www.irem.univ-paris-diderot.fr/articles/annales_de_didactique_et_de_sciences_cognitives).

The third edition of ETM was held in Montreal in October 22-23-24, 2012. Proceedings are available online (http://turing.scedu.umontreal.ca/etm/documents/Actes-ETM3.pdf).
Papers in this symposium have been reviewed in an editorial process for publication in a special issue of the journal RELIME: El trabajo matemático – puntos de vista y perspectivas, volume 17 (4), I and II.

The meeting ETM4 took place from June 30 to July 4, 2014 in El Escorial, in the prestigious summer programs supported by the Universidad Complutense de Madrid. The publication of the proceedings is in the process of finalization.
