This article explores how teachers and pupils construct and negotiate discourses around comic books as part of interaction in the classroom from a New Literacy Studies perspective. The combination of imagery and text, the essence of comics, makes them relevant tools for exploring how literacy is constructed in social interaction in the classroom. The analysis is based on video material from two different Swedish schools, one class in Grade 3 and one class in Grade 8. Nine interactional sequences were initially found, and these have been analysed using a qualitative discursive psychological approach, investigating how assessments are utilized to perform social actions – how participants use assessments of comics as easy or difficult reading, or assessments of themselves or others as being or not being comic book readers – to make something happen in interaction. The results show that participants utilize discourses of personal, visual and textual literacy to construct a comics literacy in which image and text are both construed as important for, as well as a difficulty in, reading comics. This demonstrates constructions of comics literacy and readership, how personal experiences of reading comics are important and the importance of broadening the view of comics as school literature.
