Which program emphasizes student interaction across languages while ensuring all students learn both languages?

The program that emphasizes student interaction across languages while ensuring all students learn both languages is dual-language immersion. This approach is designed to develop proficiency in two languages by integrating speakers of both languages in the same classroom. Students engage in activities that require them to use both languages, thus promoting language skills and cultural understanding.

In dual-language immersion, both English-speaking and non-English-speaking students learn together, allowing them to support each other's language development through collaborative learning and structured interactions. This model not only fosters bilingualism but also aims for high levels of academic achievement in both languages by immersing students in a curriculum delivered in both of their target languages.

The other choices have different focuses. Transitional bilingual education typically aims to transition students from their native language to English and may not emphasize ongoing bilingual proficiency. Bilingual special education addresses the needs of bilingual students with disabilities, focusing more on special education strategies than on dual-language goals. Maintenance bilingual programs aim to preserve the native language while also developing English skills, but they may not promote as much interaction between different language speakers as dual-language immersion does.
