Item does not contain fulltext Preschool children's vocabulary mainly develops verbal through interaction. Therefore, the technology-enhanced storytelling (TES) activity Jeffy's Journey is developed to support parent-child interaction and vocabulary in preschool children. TES entails shared verbal storytelling supported by a story structure and real-time visual, auditory and textual prompts on a tablet computer. In this exploratory study, we investigated how TES influenced parent-child interaction and vocabulary. An experimental pretest-intervention-posttest design was followed with 44 3-year-old children and their parents in the experimental group and 27 peers in the control group. Results revealed that TES stimulated active child involvement and generated parent-child interaction, yet a great variety in TES characteristics both in time spent and usage of prompts was found among participants. Dyads that spent more time on story phases showed more and higher quality parent–child interaction. The usage of prompts was associated with improved parent-child interaction quality. Finally, an effect of TES was evidenced on children's productive vocabulary knowledge. To conclude, this study demonstrates that TES can be considered as a promising context for fostering parent-child interaction and children's vocabulary development. 14 p.
