Abstract:
This study systematically investigates the theoretical connections, practical effectiveness, and pedagogical implications of linguistic environments for foreign language acquisition. Grounded in the Input Hypothesis, Interaction Hypothesis, Sociocultural Theory, and Output Hypothesis, this study elucidates the theoretical pathways through which linguistic environments systematically facilitate language internalization via four core mechanisms: providing comprehensible input, triggering meaning negotiation, enabling social mediation, and driving linguistic production. Empirical analyses reveal that immersive environments significantly enhance pragmatic fluency through high-frequency authentic input and obligatory output, while technology-enhanced environments optimize accessibility and processing depth of learning resources through spatio-temporal extensibility, intelligent feedback, and multimodal input. The research demonstrates that environmental efficacy hinges critically on the tripartite mediating roles of learner agency, motivation, and affective factors: agency drives deep processing of resources and environmental transformation; motivational orientation dynamically responds to environmental shifts; and affective filtering directly regulates cognitive resource allocation. Accordingly, optimizing foreign language pedagogy necessitates integrating three-dimensional approaches: constructing multi-dimensional environments harmonizing virtual and physical spaces to enhance cultural authenticity and technological affordances; deepening metacognitive and strategic training to activate learners' agency in environmental adaptation; and establishing affective security support systems to achieve optimal allocation of cognitive-affective resources.
