Museums’ roles are diversifying considering their dynamic relationships with the present-day economy, society, and communities. Nevertheless, education is the main constant marketing museums’ complex activities. An important part of the educational mission of museums is designed with and for teachers and their students. Nevertheless, these partnerships are complex and they need more understanding for designing more effective educational programs. Having this in mind, the present study analyzes the way primary-school teachers in Bucharest, Romania, interact with museums and how they use their collections as educational resources in class. The qualitative investigation implemented shows that there is a high potential for partnership and teachers need more guidance and cooperation opportunities coming from museum educators and curators.
