Purpose: In this paper, the authors engage with embodied critical literacies through an exploration of the possibilities provided by the use of improvisational comedy (improv) in the classroom. The purpose of this paper is to extend understandings of critical literacy to consider how embodied critical literacy may be transformative for both individual students and classroom assemblages. The research question asks: how might improv, as an embodied literacy practice, open up spaces for critical literacy as embodied critical encounter in classroom assemblages? Design/methodology/approach: The authors used case study methodology informed by post-qualitative research methods, and in particular, posthuman assemblage theory. Assemblage theory views the world as taking shape through the ever-shifting associations among human and more-than-human members of an assemblage. The case study took place in a sixth-grade classroom with 28 11-year-olds over a four-month period of time. Audio and video recordings provided the empirical materials for analysis. Using Bruno Latour's three stages for rhizomatic analysis of an assemblage, the authors mapped the movements of participants in an assemblage; noted associations among those participants; and asked questions about the larger meanings of those associations. Findings: In the sixth-grade classroom, the dynamic and emerging relations of the scene work and post-scene discussion animate some of the ways in which the practice of classroom improv can serve as a pedagogy that involves students in embodied critical literacy. In this paper, the authors are working with an understanding of critical literacy as embodied. In embodied critical literacy, the body becomes a resource for that attunes students to matters of critical importance through encounter. With this embodied attunement, transformation through critical literacy becomes a possibility. Research limitations/implications: The case study methodology used for this study allowed for a fine-grained analysis of a particular moment in one classroom. Because of this particularity, the findings of this study are not considered to be universally generalizable. However, educators may take the findings of this study and consider their application in their own contexts, whether that be the pedagogical context of a classroom or the context of the empirical study of language and literacy education. The concept of embodied literacies, while advocated in current literacy research, may not be easy to imagine, in terms of classroom practice. This paper provides an example of how embodied critical literacies might look, sound and unfold in a classroom setting. It also provides ideas for classroom teachers considering working with improv in their language arts classrooms. Practical implications: The concept of embodied literacies, while advocated in current literacy research, may not be easy to imagine, in terms of classroom practice. This paper provides an example of how embodied critical literacies might look, sound and unfold in a classroom setting. It also provides ideas for classroom teachers considering working with improv in their language arts classrooms. Social implications: The authors argue that providing students with critical encounters is an important enterprise for 21st-century classrooms and improv is one means for doing so. As an embodied literacy practice, improv in the classroom teaches students to listen to/with other players in the improv scene, become attuned to their movements and move responsively with those players and the audience. It opens up spaces for critically reflecting on ways of being and doing, which, in turn, may inform students' movements in further associations with each other both in class and outside the walls of their school. Originality/value: In this paper, building on work conducted by Author 1, the authors extend traditional notions of critical literacy. The authors advocate for developing critical learning opportunities, such as classroom improv, which can actively engages students in critical encounter. In this vein, rather than viewing critical literacy as critical framing that requires distancing between the learner and the topic, the posthuman critical literacy the authors put forward engages the learner in connecting with others, reflecting on those relations, and in doing so, being transformed. That is, through critical encounter, rather than only enacting transformation on texts and/or material contexts, learners themselves are transformed. [ABSTRACT FROM AUTHOR]
