The school institution is confronted with the great challenge of making changes, pressed by the new social configurations that appear in the beginning of the century. Among these, it is the coexistence of the new generations with the technologies, mainly TV and the computer. This study tries to understand this process and makes an analysis of the activities where the TV and the computer are used in the classes, in order to understand how the school can contribute that the students become creative and critical users of these new tools and not mere consumers of new representations of old clichés. Starting from a critical reflection on the audiovisual culture and its confrontation with the school culture, observations of classes (where the technologies are used) were accomplished, as well as appreciations of the pedagogic speech of some teachers of fundamental teaching (2o segment) of a public school of Rio de Janeiro. The result suggests that the activities that are done with the use of the technologies make it possible to enrich the oral and printed work typical of the school, since they introduce image, movement and intra/inter communicative interaction to the traditional contents. The computer specifically, has the potential of promoting a paradigm change, as it presupposes changes in the manners of learning and teaching. It was also verified that, for most of the interviewed teachers, the communication and information technologies dont have potential for transformations and they are used, mainly, as a complement to the classes. In spite of the fact that the teachers recognize that changes need to be accomplished, they don`t seem to believe that they will happen through the technologies. They believe that the machines, when entering the school, should be didactized to adapt to the school culture.
