Final answer:
Inhibiting students' use of their native language is counterproductive to developing proficiency in English.
Step-by-step explanation:
Inhibiting students' use of their native language is counterproductive to developing proficiency in English. Research has shown that allowing students to learn and use their authentic voices, including nonstandard dialects, is a more equitable practice that is both culturally responsible and beneficial to learning. For example, studies conducted by Johns Hopkins University found that students taught in both their native tongue and English make better progress than those taught only in English.
