Tandem is a small content management system that allows students to practice their speaking skills by doing synchronous pair tasks (e.g. Spot-the-difference-like activities). Its aim is to facilitate the practice of language in pairs, giving a purpose to the conversation and an extra motivation for students.
The LTI Tandem integration lets students choose a partner in their course and starts practicing language (in combination with some audio or videoconferencing tool). It also allows teachers to upload new Tandem activities previously downloaded or created from the SpeakApps OER repository.
