When you talk about contemporary museum education, the term ‘participatory museum’ immediately comes to mind. In museum context, in short, participation is co-creating interpretations, sharing experiences and combining them in order to jointly go through an exhibition. In this exchange of feelings, cultural and historical experiences, visitors and the museum, including its employees and educators, are involved. These processes would not have been possible without communication, which allows questions to be asked, views to be exchanged and social bonds to be created. For effective communication to take place, it is essential to create conditions for active language interaction. And this is why the Museum of Warsaw has developed the project entitled Warsaw for Intermediate Learners, as part of which a series of classes based on content and language integrated learning were created, as well as museum and street games, intended for foreigners learning Polish.
