A helpful approach for justifying the use of digital technology and applications in the classroom is Bill Green’s 3D model (Green, 1988; Green & Beavis, 2012). The model was originally developed for written literacy, but has also been appropriated for digital literacy. Green describes the model as ‘a holistic, integrated view of literacy comprising three interlocking dimensions or aspects’ (Green, 2002, p. 27). The three dimensions are: (SEE DIAGRAM IN ESSAY)
Operational which includes the functional abilities and techniques required to communicate with the given tool (in the case of the written word these tools would be words and letters, with the techniques being reading and writing. In the case of digital literacy, the techniques would include reading and writing, but also listening and typing. The tools would become computers, smartphones and other classroom appropriate digital devices).
Cultural which is about how to ‘make meaning in context’ (Bulfin & McGraw, 2015). Literacy is more than the ability to operate the tools of the medium, it also requires an understanding of cultural contexts including meanings, values, motivations, passions, beliefs, ideologies, situations and relationships.
Critical which acknowledges that literacies are socially constructed. ‘The critical dimension draws attention to issues of power and how some forms of literacy are more dominant – or socially powerful – in some contexts than others’ (Bulfin & McGraw, 2015).
