This collaborative action research project in Alberta, Canada, explored how dual-language books (DLBs) can foster literacy instruction and learner engagement through language awareness. Canada's changing demographics have resulted in mother tongue diversity and many urban schools identifying at least 25% of students as being English language learners, making it crucial to include a mix of languages in classroom interactions to engage all learners. The case study combined prereading linguistic prompts with a reading of 10 DLBs, one each week, by guest readers in Urdu, Tagalog, and Spanish, alongside the teacher reading in English. Video recordings and surveys collected data on the teacher's, guest readers', and learners' reflections on the experience. Findings indicate that regardless of the learners' linguistic heritage or English language competence, the DLBs offered a unique support for literacy engagement while fostering a focus on language awareness, reading strategies, and higher order engagement with text.
