Langue française - Année 2001 - Volume 131 - Numéro 1 - Pages 89-105Jean-Claude Beacco : Les savoirs linguistiques « ordinaires » en didactique des langues : des idiotismes This article bears upon the necessity, as regards foreign language learning and teaching, to identify and characterise ordinary (as opposed to academic) knowledge, a specific and important component of learning /teaching situations and contexts. In this respect, idiomatic expressions, which come under grammar and /or lexicon and /or discourse, may be considered as a specific type of ordinary knowledge, on account of their diversity and of the cross-linguistic perceptions and representations associated. Contrastive bilingual inventories of idiomatic expressions, on an extensive and structured basis, are suggested. Not only they are useful for learning /teaching at advanced levels, but they also contribute to an understanding of the morphosyntactic image of the foreign language, such as it is perceived by the non-native learners, as a part of of a wider body of representations. 17 pages Source : Persée ; Ministère de la jeunesse, de l’éducation nationale et de la recherche, Direction de l’enseignement supérieur, Sous-direction des bibliothèques et de la documentation.
