The article discusses the results of research on the identification of parameters for the diffusion of the concept of sustainable development through an interactive museum exposition. Based on the analyses of interviews with museum visitors, we identified some individual obstacles, mainly those related to personal engagement necessary to the appropriation of the concept. We concluded that the obstacles can be situated at different levels, some being related to the cognitive development, some more related to the emotional domain, the ethical domain, or to certain aspect of reality.
