In this article we introduce a research strategy that involves the making of visual maps by individuals in response to their interactions with artworks. The maps record the meaning-making processes involved in the encounters and provide us with permanent records of otherwise ephemeral experiences. The case study presented here provides data for comparisons between three visits each to two artworks exhibited at the Calouste Gulbenkian Modern Art Centre in Lisbon. We conclude that our meaning-making strategy is important for its own heuristic research value in both formal and non-formal educational contexts, as well as providing an instrument for the training of teachers and museum educators.
