Many accounts explaining teachers' lack of engagement with new technologies in their classrooms engage with discourses that blame their lack of time, expertise, or enthusiasm. In this paper I offer an alternative reading that provides a more agentic explanation. A rhizotextual analysis is undertaken that reveals the connections between teachers' talk and the institutional and societal discourses that ascribe value and worth to particular approaches to using new technologies and their associated digital texts in literacy classrooms. These approaches involve a focus on the technical or operational skills required to use new technologies and the over-emphasis of production work when engaging with digital texts. Taking up these discourses (im)plausibly constitutes teachers as experts and professionals, rather than the more common deficit construction of them as lacking in the skills, knowledge or even creativity required to engage in more meaningful and challenging ways with the literacy resources that young people require in the twenty-first century.
