Language instruction greatly impacts cognitive development by enhancing various cognitive skills such as critical thinking, problem-solving, and creativity. Learning different languages improves brain plasticity, allowing for better neural connections and facilitating overall cognitive functioning. It also enhances communication skills and cultural awareness, fostering a broader worldview. Moreover, bilingual or multilingual education has been linked to delayed onset of cognitive decline in older age. Thus, effective language instruction is essential for holistic cognitive development in students, enriching their learning experiences.
