Subclaims¶

q3 i? In Experiment 1, a significant interaction emerged between experimental manipulation and type of propositions produced, F(1, 37) = 19.27, p < .001, with the effect especially strong for explanatory statements. → Schmidt 1989

q3 · i? · causal · r2

Two-way ANOVA of Experiment 1 free-recall protocols (condition between subjects, proposition type within subjects) showed the treatment affected both descriptive propositions, F(1, 37) = 12.32, p < .01, and explanations, F(1, 37) = 47.24, p < .001, with explanations showing the larger effect; the experimental group produced "more than three times as many" explanatory propositions.

"However, a significant interaction effect emerged between experimental manipulation and type of propositions produced, F(1, 37) = 19.27, MSe = 5.84, p < .001."

Discussion¶

Related Claims¶

• The text-recall benefit of problem analysis is confined to explanatory propositions; descriptive facts are not better remembered — possibly the same claim (merge candidate)
• The recall benefit of prior problem-based discussion applies to both explanatory and descriptive propositions, with no interaction between treatment and proposition type — reports the opposite
• Problem-based tutorial discussion of a relevant problem before studying an expository text increases the number of accurate propositions recalled from that text — a broader claim this one bears on
• Problem-based discussion prior to studying a text does not increase the number of inferences during immediate free recall — related
