Mi idioma, mi comunidad: español para bilingües, is an open-access textbook for Heritage Language Leaners of Spanish that centers on students’ experiences with language, identity, and belonging in the Midwest through real-world applications. It uses a project-based approach that outlines how students engage in real-life applications by exploring culturally relevant topics in language use, arts, festivals, food, ethnography, oral history, digital lives, and the university. Through multimedia such as podcasts, videos, neighborhood maps, and music, we promote interactive exploration of culturally relevant content while supporting students’ language maintenance and growth.
