Joan Kelly Hall is Professor of Applied Linguistics at Penn State University. Her research centers on documenting the specialized interactional practices and actions of teaching-and-learning found in instructional settings. The aim is to enhance empirical understanding of the specialized repertoires by which instructional projects are accomplished at a level of articulation that allows researchers and teachers to see the work that is done in instructional settings in new and potentially transformative ways. Her work appears in journals such as Applied Linguistics, Language Teaching, Modern Language Journal and TESOL Quarterly. Her recent books include Essentials of SLA for L2 Teachers: A Transdisciplinary Framework (2018, Routledge) and The Embodied Work of Teaching (2019, ed. w S.D. Looney, Multilingual Matters).
