This study examines the effects of four types of reading comprehension questions--immediate, non-immediate, summary, and unanswerable questions--that linguistically diverse and predominantly low-income parents asked their fourth graders on children's text retellings. One-hundred-twenty (N = 120) parent and child dyads participated in a home visit study in which they talked about narrative and informational texts. Moderation analyses indicated that immediate questions and non-immediate questions had a more positive effect on student retellings of an informational text and a narrative text, respectively, for less proficient than more proficient readers. These findings suggest that parents may be able to help their children, particularly less proficient readers, with text memory and text comprehension by asking specific types of questions.
