Bringing together experienced classroom researchers and teacher educators from different countries where tasks are playing an influential role in language education, this collected volume critically explores how TBLT research can engage with pedagogy, and how TBLT pedagogy can engage with research. A defining part of the TBLT project has always been a dual concern - both with the nature and use of tasks in language teaching, and with empirical research to guide and support classroom practitioners, the two concerns suggesting a central and reciprocal relationship between research and pedagogy. However, this relationship has at times been unbalanced, and its centrality has sometimes gone by default, problems which this volume aims to address. The introduction proposes criteria to improve the congruence between the research base of TBLT and the concerns and terms of reference of classroom practitioners. Using a range of methodologies, the individual chapters illustrate and explore different aspects of this theme. The book will be of interest to all those wishing to further their understanding of - and/or investigate - the use of TBLT in educational contexts.
