Assessing what makes a good exhibit is an important issue but definitely not an easy one. Defining objectives and assessment criteria for developing or purchasing an exhibit can easily become a wish list which isn’t easily attained. The purpose of this session is to provide a balanced view of an exhibit over its lifetime, starting with its selection, then its maintenance and finally its evaluation. The conversation will focus on getting achievable and measurable results as well as developing awareness of trade-offs and the need to prioritize. This session will begin with short background presentations. The first two presentations will provide examples of criteria used for selecting and developing exhibits. The next one will give us more in-depth knowledge on one important criteria for all interactive exhibits: “longevity-maintenance”. The last two presentations will explain the importance of evaluation and its methods in order to continue to improve exhibits. Group work and discussions will follow. Specific interest areas may be: exhibition themes, the level of abstraction of an exhibition, a pedagogical approach, the age of the targeted audience, and more.
