Investigating the effectiveness of fantasy stories for teaching scientific principles.

Educational media often contain fantastical information. Although some prior research suggests that this information interferes with children's learning, other work shows that fantasy benefits learning under certain circumstances. To investigate this issue and to clarify how different types of fantastical events might affect children's learning, we presented preschoolers (N = 99 in Study 1; N = 101 in Study 2) with stories that contained events that violated real-world physical laws, violated real-world biological laws, or did not violate any real-world laws. Within each story, we embedded two pieces of educational information, one each from the domains of biology and physics, to test (a) whether there are benefits of fantastical information on learning and (b) whether such benefits are domain specific. Across both studies, we found that children generally learned both types of information best from the story with physical violations, suggesting that such events can bolster children's learning.
