This text responds to changing literacy practices in the digital age by developing an interdisciplinary framework for analysis of digital content created by students. Drawing on scholarship that expands traditional understandings of literacy to account for new ways in which students engage with interactive text and media, Aguilera develops a methodological toolkit for formal analysis of multimodal representations. This book frames the central challenges faced by researchers entering the field of digital literacy studies, presents a nuanced discussion of digital mediation, and brings these topics to life in the case study of a Code Club, a library-based computer programming club for elementary, middle, and high school students.The three-dimensional framework, which offers a schema for analysis of multimodal content, computational procedures, and contextual factors involved in the creation and interpretation of digital content, serves as a much-needed framework for the critical analysis of digital multimodal composition. This text will benefit researchers, academics, and educators in the areas of language and literacy, multimodality, and technology and digital innovation in education.
