  The Documentational Approach To Didactics (DAD) aims to study teachers'
professional development through their interactions with their resources
for/from teaching. It has been introduced in the French community of didactics
of mathematics in 2007, then extended at an international level. It has been
introduced as an entry in the Encyclopedia of Mathematics Education in 2020.
The DAD-Multilingual project (2020-2021) is dedicated to gather and confront
the translations of this entry towards 14 languages. The project main goals
are: making available -- for students as well as for researchers - a
presentation of DAD in various languages; deepening the DAD concepts themselves
in thinking their possible instantiations in different languages; questioning
the translation processes; and questioning the notion of resource itself,
resource for/from teaching. The lecture presents this project, and draws some
lessons from its first steps.
