Abstract
Mathematics education seen both as a field of research and as a field of practice is a multicultural field. For a while, this essential characteristic of the field has been underestimated but this is no longer the case. Both theoretical frameworks and empirical research help us today better approach this phenomenon, understand its impact on the field, reflect on research outcomes and the value of knowledge progressively built as well as on the challenges that we globally face as a community. In this lecture I would like to share with the audience my vision of this evolution and of the potential it offers for the field of mathematics education, relying on my personal experience as a researcher raised in a specific culture but also involved in many international collaborations, and on my engagement in ICMI, the International Commission on Mathematical Instruction, an institution which, for more than one century, has tried to contribute to the development of mathematics education through international exchanges and collaboration.
