**Plenary BAAL 2023** **Open scholarship in Applied Linguistics: Past, present, and future** Emma Marsden, University of York Cylcia Bolibaugh, University of York Meng Liu, Beijing Foreign Studies University Open scholarship aims to make the processes and products of research transparent, free, findable, and re-usable. It is relevant to every stage of research and draws in an enormous range of rationales, activities, infrastructures, and behaviours. In this plenary panel, we will consider the foundations, state-of-the-art, and future directions of open scholarship with particular reference to applied linguistics as well as looking beyond to our sister disciplines. The driving forces behind open scholarship can relate to economic, equality, diversity, scientific, and philosophical rationales. Reviewing these motivations, we highlight how each promotes different kinds of open scholarship practices, and we consider some of the early initiatives, such as IRIS, and their challenges. The current state of open science is then reviewed by examining specific practices that are more recently becoming established, such as OASIS, and institutional and association initiatives such as Educational Researchers for Open Science (EROS) and Open Applied Linguistics (an AILA Research Network). We discuss what these initiatives could mean for the quality and scope of applied linguistics work. These initiatives harbour great potential but they only mark the beginning of a long journey. Finally, we discuss what is needed going forward to ensure equitable and sustainable open scholarship, emphasising the need for grass roots initiatives, top-down infrastructure and mechanisms, a robust metascience to support evidence-informed interventions, and the need for the kinds of community action that the professional associations are well placed to offer. To fully realise the potential for open scholarship for improving the way we conduct and disseminate research, we must continue to experiment, evaluate and evolve. We hope our plenary panel serves as a catalyst for further discussion and action and inspires researchers from diverse backgrounds to journey—be it gradually or rapidly—towards a more open future. Colleagues interested in learning more are encouraged to join the Local Organising Committee’s symposium workshop which will provide more practical insights into the practices discussed in the plenary.
