Education in the app store: using a mobile game to support U.S. preschoolers’ vocabulary learning

Abstract

Despite the prevalence of educational apps for children, there is little evidence of their effectiveness for learning. Here, children were asked to learn ten new words in a narrative mobile game that requires children use knowledge of word meanings to advance the game. Study 1 used a lab-based between-subjects design with middle-SES 4-year-olds and used a receptive vocabulary test to examine whether children learned the game’s words. Children who played the game answered more questions correctly than children who did not play the game. Study 2 used a within-subjects design with low-SES preschoolers who played the game four times as part of a larger classroom intervention. Children showed evidence of learning on both a receptive and an expressive vocabulary measure. The difference between pre- and post-test scores was significantly larger for target words than for five non-exposure control words. Results show that both middle-SES children in the lab and low-SES children in the classroom learned new vocabulary from an interactive mobile game, suggesting that developmentally-appropriate mobile games show promise for vocabulary learning.
