The MARVEL project (Museums Actively Researching Visitor Experiences and Learning) was a collaboration between the University of Technology Sydney, the Australian Museum, the Royal Botanic Gardens Sydney and Environmetrics Pty Ltd. The project team members are Janette Griffin, Lynda Kelly, Janelle Hatherly and Gillian Savage respectively from each of the above organisations. The aim was to develop a set of ‘tools’ for measuring aspects of learning in any cultural institution, and that could be used by staff who may have little evaluation experience. Three tools were developed and tested to meet this need. This paper reports on the development and initial testing of these tools.
