Correct Response: D. Conducting instructional conversations on a regular basis provides English language learners with multiple exposures to and opportunities to use new English academic vocabulary and language structures in relevant contexts; that is, in meaningful discussions related to the content they are studying. A is incorrect because the focus of the conversations is on content, not error correction, so students do not necessarily receive corrective feedback on their language output. Instead, students are guided and supported during the discussion by the teacher. B is incorrect because instructional conversations use an oral language strategy to promote content learning, not vice versa. C is incorrect because in the scenario described, the teacher leads expanding-level English language learners in the guided discussion, so the teacher is the only proficient English speaker in the group.
