This study investigates the communication practices of four teachers in 3rd to 6th grade classrooms with 9 deaf students with limited language proficiency and in stages of emergent writing development. Analyzing language modalities, utterance types, and class interactivity, we found that teachers using American sign language used student-centered approaches, generating a greater number of directives and responsive utterances. They persevered in increasing students' engagement and were successful in clarifying misunderstandings. Teachers using spoken English used teacher-centered approaches, making general comments directed at the whole class, which consequently reduced student participation and responsiveness. They also largely avoided repairing communication breakdowns with emergent writers, focusing instead on those with greater auditory and speaking abilities. These patterns reveal disparities in classroom communication that can affect student learning. Our findings highlight the need for teacher preparation programs to equip teachers with skill sets to employ accessible and effective communication during instruction, especially with deaf students who are still developing foundational language and writing skills.
