Disciplinary literacies are explored using dimensions of academic language. Through a sociocultural perspective on literacy, students will develop the knowledge and expertise necessary to teach K-12 learners to negotiate and interpret complex texts and other multimodal forms of linguistic expression and representation that are associated with distinct disciplines. A variety of research-based strategies and practices for effective instruction in disciplinary literacies are reviewed and studied. Specific focus is on designing and delivering authentic instruction across the curriculum and for selecting materials appropriate for diverse learners at various stages of language and literacy development.
