In this chapter, I argue that Open Science and Open Education practices are critical to addressing the much-discussed “gap” between applied corpus linguistic research and language learning and teaching practice. In particular, I focus on practical ways to facilitate the accessibility and sustainability of research findings and dissemination projects. Amongst other examples, I draw on my experience of leading a project in which pre-service English teachers co-created the Open Educational Resource (OER): “Creating Corpus-Informed Materials for the English as a Foreign Language Classroom: A step-by-step guide for teachers using online resources” (Le Foll, 2021; https://elenlefoll.pressbooks.com).
