Which statement explains why ELLs in additive bilingual programs often perform better academically in L2?

The statement about continued development of their native language as a foundation highlights a crucial aspect of additive bilingual programs. These programs support and enhance a student’s proficiency in their first language while simultaneously teaching them a second language. This approach allows ELLs to build upon their existing linguistic skills, which can lead to improved cognitive abilities and academic performance.

By nurturing both languages, students can express complex ideas, engage in critical thinking, and transfer skills from their native language to English. When students maintain and develop their native language, they are not only preserving their cultural identity but are also strengthening their overall language proficiency, which is essential for academic success in any language. This solid foundation in their first language ultimately supports their acquisition of a second language, making them better equipped to handle academic content in both languages.

In contrast, the other options suggest approaches that do not necessarily support a dual-language development framework. Increased exposure to English grammar, while beneficial, does not account for the foundational role that the native language plays in language acquisition. Emphasizing English-only instruction may limit the development of students’ native language and neglect the cognitive benefits of bilingualism. Finally, while technology can enhance language learning, it is not the core reason why the preservation and development of the native language leads
