The integration of technology in language teaching has been one important topic in language education and teacher training. Teacher education has been one of the aims of telecollaboration since the beginning of the 2000’s. While the first pioneers worked with small groups of students (Develotte, Mangenot, & Zourou, 2005; MüllerHartmann, 2006), more recent projects are widening the application of telecollaboration for teacher education (Baroni et al., 2019). In the present article we present an adaptation of the model of Le Français en (Première) Ligne (hereafter F1L) proposed by Develotte et al. (2005) in two telecollaborative projects aiming at developing trainees’ techno-semiopedagogical competences.
