What principle is reflected in the actions of a teacher who learns key phrases in the first language of English Language Learners?

The principle reflected in the actions of a teacher who learns key phrases in the first language of English Language Learners is that continued development in the first language supports English acquisition.

When teachers take the initiative to learn and use the first language of their students, it creates a more inclusive and supportive learning environment. This practice acknowledges the value of the students’ native language and promotes their ongoing development in that language. Research indicates that proficiency in a child's first language can facilitate the learning of a second language, in this case, English. This is because the cognitive and linguistic skills developed in the first language can transfer to learning English, making the acquisition process more effective.

Furthermore, supporting students in their first language can boost their confidence and provide a sense of belonging, which are critical for successful language learning. This approach recognizes that multilingualism is an asset rather than a barrier, reinforcing the idea that nurturing a child's first language can significantly enhance their ability to learn a second language.
