Prior knowledge activation: Inducing engagement with informational texts.

Failure to engage with informational texts is a problem frequently noted at the high school level, at which students are expected to read independently. As a means of addressing this issue, a prior knowledge activation strategy (PKA) was taught to ninth-grade students in which they were encouraged to make spontaneous connections between their personal knowledge and informational texts. Students who learned to use the PKA strategy consistently outperformed students in a main idea (MI) treatment group and those in a no-instruction control group on application-level comprehension questions but not literal-level questions. A second study replicated the operations of the first study, with the addition of an MI-PKA treatment designed to combine both strategies. Both the PKA and the MI-PKA combination groups performed higher on application-level comprehension questions and demonstrated more positive attitudes toward reading than the other groups.
