Final answer:
The instructional recommendation not encouraged in the text is Focusing solely on a student's native language. The texts promote bilingual education and respecting students' linguistic diversity, and suggest that bilingual education helps students progress in academic English better than monolingual instruction.
Step-by-step explanation:
The instructional recommendation from the text that is not encouraged is Focusing solely on a student's native language. Academic success is highly dependent on proficiency in academic English; hence, strategies are recommended to help students not only improve in English but also receive support without neglecting their native tongues. As per the given texts, supporting multilingualism and a student's right to their own language are crucial, reinforcing the use of their native language alongside English to enhance understanding and performance across subjects.
Research, like the studies from Johns Hopkins University mentioned in the text, suggests bilingual education contributes to better academic progress than instruction in English alone. It is also important to respect the cultural and linguistic diversity among students by appreciating their unique dialects and patterns of speech, reinforcing the idea that academic circles should celebrate language diversity and not just the dominant General American English.
It's worth noting that focusing exclusively on a student's native language in an English-dominant academic setting would not align with enhancing academic English skills, providing additional support for struggling English learners, or implementing strategies to enhance English language proficiency—all of which are recommendations given in the text for fostering educational success.
