Preschool teachers usually read the narration of each page from print storybooks and show the illustrations around afterwards. However, presenting the illustrations at the same time as the oral narration might be more effective for children’s vocabulary development. The aim of the present study was to examine the effect of different timing between pictures and text during a story reading on young kindergartener’s vocabulary acquisition. 22 children listened to digitalized storybooks presenting the visual and the verbal information either at the same time or successively. Children’s book-based vocabulary growth was assessed. The findings showed that simultaneous storybooks were more beneficial than non-simultaneous ones on young kindergartner’s vocabulary development. Students with larger initial vocabularies benefited more from the simultaneous storybooks than the non-simultaneous ones. However, the mode of presentation made no difference in learning gains for students with low initial vocabulary knowledge. Digitalized storybooks are suggested for preschool reading sessions.Show less
