Question asking practice fosters aspects of curiosity in science content in young children.

Children who are more curious learn more in school, but little is known about how to promote curiosity-driven behaviors. In a preregistered experiment, 103 children (54 boys, 49 girls, ages 5-7 years) were randomly assigned to a condition in which they were encouraged to ask questions, or to listen carefully, during eight one-on-one science lessons over 2 weeks. Children in the question-asking condition valued new science information significantly more than children in the listening condition (Wilcoxon r = 0.23). Children with less background knowledge, as measured by their baseline vocabulary and science achievement, showed greater curiosity and learning benefits from question-asking. These results suggest that practice with question-asking can boost some aspects of curiosity and learning in science domains.
