Today, in a society where the commercialization of culture is becoming increasingly important, the museum community has begun to adapt through a transformation of its mediation process. Nowadays, in most cultural institutions, new Information and Communication Technologies (ICTs) have become a necessary element of a playful and attractive tour. But what about their didactical and pedagogical contributions, particularly with the prospect of learning historical thinking? Firstly, this research offers an attempt of operationalization of the actual and supposed ICTs’ contributions contained in the scientific literature. Secondly, this research shares the results of observation and study of technological devices using ICTs in a selection of museums and exhibitions about the Great War which confirm the high potential of new technologies, in relation to our operationalization of the real and supposed effects of ICTs.
