This study examines the relationships between student literacy performance and discussion-based approaches to the development of understanding in 64 middle and high school English classrooms. A series of hierarchical linear models indicated that discussion-based approaches were significantly related to spring performance, controlling for fall performance and other background variables. These approaches were effective across a range of situations and for low-achieving as well as high-achieving students, although interpretations are complicated because instruction is unequally distributed across tracks. Overall, the results suggest that students whose classroom literacy experiences emphasize discussion-based approaches in the context of high academic demands internalize the knowledge and skills necessary to engage in challenging literacy tasks on their own.
