Both models were designed during research conducted within a museum setting in an interactive scientific and technical exhibition at the Cité des Sciences et de l'Industrie (Museum of Science and Industry) in Paris. The models presented here are consistent with the analysis of communicative interactions produced in any learning situation: the first model, the Media Square, is suitable for analyzing asymmetric dyadic exchanges (parent - child), while the second model, the KITLoK Model, is designed for analyzing polyadic situations, whether asymmetric or symmetric [tutor - student (s)]. The models intend to chart learning interactions in an educational situation which benefit from dual mediation: both human (the tutor, as a 'human mediator') and instrumental (interactive museum tools, as a 'technical mediator'). Both models will be discussed as regards the models of origin that inspired them. These models of origin will also be presented in the first part of the paper. http://pubs.sciepub.com/education/3/7/18/education-3-7-18.pdf interaction analysis interactive learning analysis models Media Square Model KITLoK Model
