Comprehension, Diagram Analysis, Integration, and Interest: A Cross-Sectional Analysis.

The current study examines a multidimensional set of outcome variables to understand whether different pre-reading scaffolds influence students' text comprehension, diagram analysis, text integration, and interest; and investigates these constructs cross-sectionally to identify any progression as students move across grades. One-hundred fifty-six 3rd through 6th grade students enrolled in a public laboratory school were randomly assigned to one of three pre-reading conditions intended to activate or build students' topic knowledge. Students completed a series of before, during, and after reading activities while engaging with grade appropriate texts about the topics of ecosystems and living things. Results indicate that there were no significant differences between the three pre-reading conditions on any of the four constructs of interest. Students across grade levels performed well on multiple-choice comprehension questions, but not as well on diagram analysis questions or an open-ended integration task. Implications and future directions are discussed. [ABSTRACT FROM AUTHOR]
