Supporting second language learner reflection in teletandem videoconferencing through the visualisation of conversation metrics




Teletandem, virtual exchange, videoconferencing, conversation metrics, reflection, L2L


Videoconferencing is a popular mode of communication in virtual exchange (VE) settings. Recognising technological affordances of teletandem via videoconferencing, we developed a web-based system, L2 (second language) Learning system (L2L), for university language students’ teletandem reflections. L2L provides visualisations of conversation metrics, which students reflect on as a means of formative self-evaluation. It was integrated into several language courses across 10 European universities and deployed for three consecutive semesters involving 926 students. This practice report presents the main features of L2L and the student feedback received in one Irish university, with a view to support reflection in teletandem and address some inherent challenges in this VE setting.
