Delivering citizenship education and pass down at school values that are essential to uphold social and political cohesion are burning issues in the French society, especially in these times of crisis. In what way do verbal interactions occurring in didactic context participate in this undertaking? To answer this issue, we put together a corpus made up of the transcripts of eight lessons observed in 3rd cycle classes located in south east of France. These data will be analysed with pluralist tools, united by a sociolinguistic approach. We aim to show how verbal interactions contribute to shape citizens, particularly by allowing co-construction of meaning, conflict regulation, otherness encounter, as well as plurality and variation awareness-raising.
