This contribution is a reaction to Prof. Mercer's presentation à the 8th session of the International Seminar "Learning and Teaching", at the French Institute of Education/ENS de Lyon. Reacting to the inspiring presentation of Pr. Mercer, I tried to re-situate the issue of the interlinking of language and learning (and even language and education at large) in a French context, from the restricted point of view of “didactique du français” (theory and practice of French language and literature teaching). I’d like to make Pr feel the way an French scholar, in that peculiar field, could be receiving his work and assumptions.
