This commentary includes consideration of theory, opinion, empirical work, evaluative work and practice in a subset of papers that appeared in ARAL (2016) on task-based language teaching. Addressing the wider logic, theoretical underpinnings and instructional implications of TBLT is a serious applied linguistics challenge and one that the TBLT area is increasingly in a position to engage with in the search for evidence-based solutions to problems in designing, implementing and assessing the effects of TBLT. The contributors take a sometimes approving, occasionally critical and always forward looking perspective on the contributions of ARAL 2016 and the directions and challenges facing the field.
