This dissertation explored existing and evolving narratives around gender and athletic identity in texts written for and aimed at children and how literacy took root within after-school spaces, particularly after-school programs that foster children's attunement to the physical body, such as sports. I collaborated with one school site's Girls on the Run after school program to explore literary narratives about gender, belonging, athletic identity, the body, physical health and well-being, and more through picturebooks and other materials (e.g., videos, author visits). I drew across several interdisciplinary bodies of scholarship to guide my inquiry that included feminist perspectives on embodiment, critical theories of race, critical literacy, and sports as an entry point for critical conversations with children. I engaged in qualitative data collection and analysis across several data sources (e.g., videos, audio recordings, fieldnotes and memos, children's artifacts). Audio memos after each session served to guide my analysis and engagement with focal data and moments from the interactions with children and teachers. My findings illustrate: 1) existing and evolving narratives around gender and athletic identity in relation to the persistence and resistance to binaries in texts written for and aimed at children, specifically in the elementary ages K-5, 2) conversations for both teachers and children related to gender identities and the complex role of the gender binary in children's responses to texts that offer routes to challenge binary identities, and 3) how embodiment takes root within after school spaces and the potential for spaces in and out of school. My study has both pedagogical and theoretical implications for the significant role that narratives and texts can play in rupturing existing or normative beliefs around binaries and identities, particularly in drawing on embodied ways of knowing, thinking, and disrupting. Furthermore, this study contributes to the research literature on the importance of locating ways for children to access critical conversations about texts that speak to their own and others' lived experiences of embodied identities. Finally, this study has methodological implications in the field's conversations of how concepts from affect theory can be taken up as method in critical, justice-centered research in literacy studies.
