Dual language education is a comprehensive pedagogical approach and academic field of study concerned with the systematic use of two languages within an educational setting to promote bilingualism, biliteracy, academic achievement in both languages, and cross-cultural competence among learners. This concept investigates language acquisition processes in bilingual contexts, effective instructional strategies for diverse linguistic populations, curriculum design for dual language environments, and the sociolinguistic and cognitive outcomes of bilingual schooling, holding significant implications for educational policy, practice, and equity.
