Final answer:
Research supports the statement as true; students taught in both their native language and English perform better academically, and bilingualism provides cultural and economic benefits.
Step-by-step explanation:
The statement that bilingual individuals perform better on tests administered in their native language than on tests administered in English or their second language is generally True. Research by Johns Hopkins University (Slavin et al. 2008) indicates that students taught in both their native language and English make better progress academically than those taught only in English. This dual-language approach not only facilitates a smooth transition to becoming fluent in English for non-native speakers, but it also contributes to academic success across multiple subjects by ensuring students do not fall behind while learning a new language.
Likewise, Lucy Alvarez's law enforcement studies are supported by her bilingual education, which aided her through grade school and is now an asset in her professional life. From this example, we see that bilingualism can offer both cultural and economic benefits to individuals and contribute to their professional growth in various fields. This underlines the importance of maintaining proficiency in both one's native language and English in bilingual educational settings.
