In this whitepaper, authors Dr. Rocio del Castillo-Perez and Dr. Julia Stearns Cloat introduce a practical framework for intentionally building cross-linguistic connections in dual-language classrooms. Grounded in research and real-world bilingual practice, the framework supports the development of metalinguistic awareness and biliteracy. Educators will find actionable guidance for planning instruction across five key linguistic domains—phonology, morphology, syntax, semantics, and pragmatics—along with step-by-step strategies for implementation.
