Gestures are a significant part of communication and carry particular weight when using artefacts such as computers. This study investigates how gestures and utterances are used as resources in the interaction between children and preschool teachers when creating stories with the computer. The data consists of observations of 17 preschool teachers and 34 children who are engaged in making stories. The interaction between the child, the preschool teacher, and the computer has been documented on videotape and analysed by Interaction Analysis. The results show the preschool teachers' decisive significance as an interplay partner for the child's appropriation of a linguistic capacity outside of a here-and-now situation.
