International audience We report on a didactic experiment carried on six classes, on three levels, between February and May 2018. Our research aims to measure the impact of several oral-based lexical teaching sessions on vocabulary reuse in written work. Lexical units on the theme of trickery are selected from written recall of tales told orally. The experiment encourages thought as to lexical choices, in reception and in production, and therefore the development of lexical skills. The results with regard to pupils’ lexical performance and motivation are very encouraging.
