In this meta-analysis, the authors synthesize results from 44 (quasi-)experimental studies on informational and narrative text structure interventions involving students in grades 4-6 in regular school settings.

Analyzes above and below average readers' informational reports, which synthesize both source texts and writer-generated materials. Concludes that general reading ability and success at synthesizing overlap, and that success at synthesis may be related to cognitive factors associated with comprehension, such as sensitivity to text structure.
