Language immersion programs play a crucial role in children's bilingual development by providing them with early and intensive exposure to a second language. Research has shown that such programs can significantly enhance children's language proficiency and cognitive abilities.

For example, a study by Lindholm-Leary and Borsato (2016) found that students in language immersion programs outperformed their peers in non-immersion programs in both English and the target language. This demonstrates the positive impact of immersion programs on bilingual development.

Furthermore, language immersion programs create a natural and authentic environment for language learning. Children are immersed in the target language throughout the school day, which allows them to acquire language skills in a context that mirrors real-life language use.

Overall, language immersion programs are instrumental in promoting children's bilingual development and preparing them for success in a multilingual world.
