This article summarises a research project with a group of twenty Singapore primary students who were introduced to computer graphics in an eight-week. programme. Their actions and artwork were closely monitored by participant observers to see how they interacted with the computers and with each other as they learned how to use the tools and exercise judgement and control. Three aspects of behaviour which seemed to be particularly significant were: watching and internalising, providing a running commentary and pointing. The children's artwork showed that they could use the computer as a tool to create artwork and engage in high-level symbol-weaving.
