Latinx curriculum theorizing is a constellation of curriculum scholarship rooted in the histories, knowledges, and everyday lives of peoples from across the Latin American diaspora. It is a framework that pushes back against demonizing stereotypes, caricatures, and colonial generalizations of an entire diaspora. Born out of resistance and liberation, it comes from the histories and practices of Latinx peoples in creating counternarratives, education reform, and activism. Specifically, Latinx curriculum theorizing includes the following: (a) Latinidad as a collective point of entry, (b) Latinx as a term, (c) history and circumstance as curricular knowledge, (d) counternarratives and testimonio as curriculum theorizing, (e) cultural knowledges of Latinx students and community as theory, (f) cultural knowledges of Latinx teachers, and (g) Latinx communities generating critical pedagogies and education initiatives. Latinx curriculum theorizing draws from a variety of Latinx philosophical traditions, including critical race theory, Latina feminist philosophy, Latinx and Chicanx studies, and various strands of Latin American, Continental, Caribbean, and Africana philosophy. While scholars who do Latinx curriculum theorizing are trained in theories such as critical race theory, feminist theory, and post- and decolonial theories, because of the subject matter and the people, this framework is the next step up in putting such foundational theories into conversation with one another. It is therefore a newly emerging framework, in the early 21st century, because it draws upon all these perspectives to account for a very transitionary, contradictory, and messy Latinx experience. What makes something distinctly Latinx curriculum is an engagement with a state of transition and liminal spaces, both pedagogically and epistemologically, with the varied and multilayered trajectories of Latin American-origin realities. Far from being a monolithic and static framework, Latinx curriculum theorizing is itself malleable, contested, and in transition. Just as Latinx itself is a contested term within academic and activist spaces, Latinx curriculum theorizing is a point of contestation that makes it a framework with porous boundaries that can explain and even redefine the Latinx educational experience. As such, Latinx curriculum lends itself to nuanced analysis and praxis for issues of gender, sexuality, ethnicity, language, migration, racial hierarchies, and colonial legacies. This type of curriculum theorizing also points to power structures from multiple social locations and offers pathways for social change and liberation.
