This study explored deaf and hearing university students' metacognitive awareness with regard to comprehension difficulties during reading and classroom instruction. Utilising the Reading Awareness Inventory (Milholic, V. 1994. "An inventory to pique students' metacognitive awareness of reading strategies." "Journal of Reading" 38: 84-6), parallel inventories were created to tap metacognitive awareness during comprehension of sign language (deaf students) and spoken language (hearing students). Overall, both deaf and hearing students appeared to have greater metacognitive awareness of ongoing comprehension and repair strategies during reading than during instruction in the classroom, but deaf students scored lower than hearing students in both modalities. Deaf students were no more likely than hearing students to report adopting inappropriate strategies, but both groups indicated they were more likely to do so in classroom contexts than during reading.
