Explaining how cities function, revealing their underlying and often invisible workings, helping children to grasp the complex urban environment in which they live – these were the challenges that led to the creation of an unusual children’s museum in Buenos Aires. Cinthia Rajschmir was a member of the team that founded the Museo de los Niños: Abasto (Abasto Children's Museum) and participated in the development of the main theme, the pedagogical content and the basic materials used for the museum’s design. She is a graduate in the pedagogical sciences and since 1993 has formed part of the editorial team of the Revista Novedades Educativas (Educational News Review). She is currently engaged in research on the history of Argentine school museums as part of a project being carried out by the University of Buenos Aires.
