Abstract Increasingly, reading research has begun to address how students’ linguistic environments may explain their reading achievement. In this exploratory analysis, we investigated how the rates of specific instructional talk moves predicted student reading comprehension achievement. Transcripts from third-, fourth-, and fifth-grade classrooms (teacher n = 31; student n = 236), were coded for nine talk moves established in the literature as involved in literacy and learning outcomes. Two-level hierarchical linear modeling was used to identify sources of linguistic comprehension, a necessary component of student reading comprehension. Controlling for students’ decoding and fluency, semantic-syntactic knowledge, and initial reading comprehension, we found two talk moves significantly predicted reading comprehension. Teacher explanations [γ07(20.89); p ≤ 0.05] and simple follow-up moves [γ06(10.44); p ≤ 0.05] provided students with explicit instruction and exposure to academic language and the positive reinforcement to encourage student attention to the learning tasks and thus potentially more language exposure. In this sample, these moves provide further support for the simple view of reading (Hoover & Gough, 1990) that suggests that fostering student linguistic comprehension is pedagogically important for student reading at these levels.
