Artanti Sari and I are presenting today at the 56th Annual Conference of the British Association for Applied Linguistics (BAAL) at the University of York. We are part of the symposium ‘The Learning of Sacred Languages’, which features papers from a forthcoming special issue of the International Journal of Bilingualism, edited by Bene Bassetti. Our paper examines the use of digital spaces by transnational Indonesian-Muslim families to support their children’s Qur’anic Arabic language and literacy development.
