This project investigates second language use and learning in the wild, that is in everyday interactions embedded in diverse sociocultural and material environments outside the classroom. We analyse language learning as an in situ process shaped by the participants’ situated practices and sensitive to the contingencies and material ecologies of different types of social activities. In addition, the project combines methods of interaction research and collaborative design to develop experiential language pedagogy that is based on the learners’ real life needs and places the language user at the centre of the learning process.
