ABSTRACT: Creating immersive language learning environments for young learners in English as a Foreign Language (EFL) contexts has been a topic of considerable interest and debate among educators. Despite numerous constraints such as time, curriculum, and stakeholder expectations, it is feasible to develop effective immersive environments. This paper explores the concept of immersion language learning, tracing its historical development and highlighting its benefits, particularly for young learners. It discusses the distinctions between total, partial, and dual-immersion programs, emphasizing the critical role of using the target language as the medium of instruction. Furthermore, it examines the cognitive and academic advantages documented in seminal immersion programs like Saint-Lambert and Coral Way. By synthesizing research and offering practical strategies for EFL settings, this paper underscores the importance of teacher commitment, the selection of appropriate materials, and the adoption of Content and Language Integrated Learning (CLIL) principles. Ultimately, the findings affirm that immersive environments significantly enhance language proficiency, cognitive flexibility, and academic achievement, advocating for their broader implementation in EFL classrooms.
