ERME anniversary panel on the occasion of the 20th birthday of the European Society for Research in Mathematics Education

The general aim of the panel was to offer a reflection on the genesis and the contribution of the European Society for Research in Mathematics Education (ERME) to research in mathematics education, regarding its past, present and future. After a short introduction, the panel focused on three topics: The ERME society, presenting a historical and present view; YERME and YESS, highlighting history and current developments related to supporting young researchers; the ERME book, focusing on its evolution, spirit and results. Each topic started with an input by two panel members who also answered questions by participants of CERME 11 sent in advance or raised during the panel. The panel was concluded by the president and the two co-chairs of the panel.
