The aim of our research is to describe and characterize didactic situations implemented to teach and learn English as a second language in primary French classes. We particularly focus on how linguistic and cultural dimensions are connected. Our theoretical framework mainly refers to the Joint Action Theory in Didactics. We also use theoretical tools that have been developed in the didactics of foreign languages and cultures. To do so, we conduct an analysis of English lessons that have been transcripted from videi recordings. These lessons take place in « ordinary » classes and in a class using a videoconferencing system. In our empirical studies, we particularly study how the learning games and the equilibration between the contract and the milieu are implemented in order to make students build knowledge, and we examine how the notion of epistemic game can contribute to our analyses. We also analyse a questionnaire that 108 primary school teachers have filled in. We particularly focus on the analysis of scenarios of teachers’ practice, in reference to which they had to situate their own practices. We bring together the observation emerging from our analyses of the lessons and of the questionnaire, and make use of these results to design of a teaching unit in collaboration with teachers,whose aim is to make students encounter a cultural piece, Roald Dahl's novel « Fantastic Mr Fox » (1974). As a conclusion, we expose our perspectives in order to re-design more thoroughly our teaching unit, in relation with the primary school teachers' training curriculum
