Classroom research has long been recommended as a fruitful avenue for English language teaching (ELT) in applied linguistics. Yet recognition of the value of practitioners exploring their own praxis has only recently come to the fore. In this plenary, I focus on Exploratory Practice, a form of 'fully inclusive practitioner research', in which learners as well as teachers are invited to integrate research and pedagogy. Drawing on studies from around the world, I spotlight the potential of learners and teachers to contribute to debates in the fields of language teaching and learning, applied linguistics and social sciences alike. This co-production between learners and teachers illuminates the nexus of research and pedagogy (praxis), providing plentiful puzzles for exploration.
