L’explicitation a-t-elle une influence positive sur l’apprentissage du lire-écrire au CP ?

This article is focused on the effects of teacher explicitation for the learning of reading and writing in first-grade classes characterized by the underprivileged social environment of their pupils. To do so, it compares the classes of a corpus based on the re-sults of the French « LirecrireCP » research and made up of eight classes : four classes evaluated as effective in the teaching and learning of reading and writing and four classes considered to be less effective. The comparison between the two groups of classes is car-ried out using an analysis grid worked out by the authors, and covers successively the volume and the frequency of expliciting exchanges as well as their occurrences according to the type of tasks, the elements emphasized in the expliciting, the use of a specific lexicon and of teaching artefacts, and finally discusses the question of the relevance of these explic-iting exchanges.
