Abstract

Disciplinary literacy refers to the specialized practices of reading, writing, and reasoning that are unique to each academic discipline—the distinct ways in which scientists, historians, mathematicians, and literary scholars construct, communicate, and critique knowledge within their fields. Although disciplinary literacy is relevant across the lifespan and across all phases of education, its demands become most salient as learners advance through schooling and encounter increasingly specialized texts and discourse conventions. It is distinguished from content-area literacy, which applies general study and comprehension strategies across subjects, and from the foundational literacy skills emphasized in the early-grades Science of Reading. Where foundational literacy concerns the components by which children learn to read (phonemic awareness, phonics, fluency, vocabulary, and comprehension), disciplinary literacy concerns how learners read, write, and think as participants in a discipline once those foundations are largely in place. In secondary teacher preparation specifically, disciplinary literacy denotes both a body of pedagogical knowledge and a set of instructional competencies that content-area teacher candidates are increasingly expected to demonstrate—including the capacity to make discipline-specific reading and writing practices visible and teachable for their students. Its theoretical foundations lie in scholarship documenting that literacy demands become more specialized, rather than more general, as students advance through schooling. As educator preparation systems, particularly in the United States, formally integrate Science of Reading principles into program requirements, disciplinary literacy has emerged as the established, though comparatively less codified, extension of that movement into the secondary content areas, where disciplinary reading and writing instruction have historically received limited systematic attention.
