Background knowledge, curriculum, and socioeconomic status : what do second-grade readers know about topics in core reading programs

"This study examined the background knowledge of second-grade students in high-socioeconomic status schools and in low-socioeconomic status schools. Specifically, the study investigated how much each student knew about concepts and topics important for comprehension, but not easily inferred, in program selections in three widely used core reading programs."--From abstract.
