With a view to better preparing teachers to engage in linguistically responsive feedback practices, we examined what 120 preservice secondary English language arts teachers (PSETs) considered to be “useful” and “appropriate” feedback to English learner (EL) writers by analyzing posts to an online database of student writing and teacher feedback. Findings of this qualitative study show that PSETs valued linguistic diversity, shared many core orientations of linguistically responsive teaching, and sought to give ELs holistic writing feedback; however, they ultimately equated useful feedback with error correction. PSETs were highly attuned to EL errors, but they were not able to connect different types of errors to language development and could not determine which errors were appropriate to correct given the student’s proficiency level. Furthermore, PSETs largely ignored ELA content and attributed appropriate EL feedback to teacher bilingualism rather than recognizing the need to learn about ELs’ interests and backgrounds. We suggest equipping PSETs with skills to learn about ELs and leveraging extant PSET attention to grammar with additional knowledge of language development processes. Identifying proficiency-level-appropriate errors could allow PSETs to selectively correct errors and provide space for more substantive feedback on ELA content.

English education researchers have established that whole-class discussions can support language and literacy learning. However, few studies have provided examples of whole-class discussions in which students explicitly reference their classmates’ ideas in order to elaborate different, but related, perspectives. Research that has described students’ uptake of their classmates’ ideas has typically portrayed disagreement either as an obstacle to student participation or as a step toward eventual consensus. In this article, I offer a sociolinguistic discourse analysis of two conversations in which a preservice teacher encouraged her urban, 10th-grade students to disagree. My analysis demonstrates the positive effects of the teacher’s use of indirect challenges and provocative paraphrases—features of the African American sociable conflict-talk practice known as The Dozens—to promote collaborative disagreement during whole-class discussion. I argue that teachers can promote collaborative disagreement in whole-class discussions by appealing tostudents’ home-cultural disagreement practices, which may already overlap with argumentation practices valued in school settings. I call for further research into the influence of teachers’ and students’ out-of-school discourses on discussions characterized by collaborative disagreement—a practice that is essential to ELA curricula and to participation in a democratic, literate society.
