The field of literacy research has seen a recent surge in scholarship focusing on how matter—both human and nonhuman—comes to matter in literacy research and practice. This article explores how new materialist theories may be recruited for literacy research motivated by an anti-racist ethic. We present an illustrative intra-action analysis of a short autobiographical video produced by Malcolm, a Black male high school student, for a digital autobiography class assignment. Our analysis, informed by both new materialist and poststructuralist theories and emphasizing both discourse and materiality, produces varied interpretations of Malcolm and his literacy practices. Based on our multitheoretic analysis, we raise ethical concerns regarding analyses of racialized students’ literacy practices that emphasize materiality and affect without also retaining a critical eye toward powerful discourses of race and racism. We end with implications and recommendations for others engaging new materialisms in literacy research.

Purpose This study aims to investigate the ways affective intensities arise in the intra-actions within an assemblage (three Black girls, objects such as computers and hoodies, institutionalized discourse associated with race and successful participation in schools) as the girls create multimodal responses to literature. This paper shows how the intra-actions among the girls and material objects produce affective intensities or new ways of being and becoming through which youth reauthor themselves as central and peripheral participants. Design/methodology/approach The authors present an illustrative case of the ways girls’ embodied literacy identities emerge when Jillian, Isa, and Rhianna intra-act with materials in an assemblage that includes their material-discursive positionings through qualitative and multimodal interaction analysis. Findings The analysis describes the ways the girls agentively participate through play, composing and moments of becoming (fluid subjectivities) that include emotive acts such as acts of solidarity, loving connectedness and possible frustration that inform who counts and who can be successful in the classroom. Research limitations/implications This single case study gives a descriptive, in-depth analysis of the ways affective intensities emerge as three girls respond to literature to understand their embodied and discursive practices within the composing process. Originality/value To fully understand agency and the students’ emergent subjectivities, the authors combine embodiment and material-discursive analysis to understand affective intensities that evolve during three Black girls’ composing processes and the ways the girls’ subjectivities shift within the intra-actions.
