Informational literacy and the use of technologies by Secondary Education students in Spain: A descriptive study. The development of Information and Communication Technologies (ICTs), together with their application to research carried out on educational areas, are factors which contribute to the promotion of a new educative model constructed on literacy-based competences and skills, and which sets technologies as essential tools for a life-long learning process (UNESCO, 2005). This is the framework where we can insert the research that we are currently carrying out, funded by the research Program I+D+I of the Spanish Ministry of Education, and in the frame of which we are developing a diagnostic assessment of informational literacy competence in students between 14 and 16 years (Secondary Education), based on the fact that one of the main aspects in knowledge generation and acquisition is the capacity to use information extracted from documents and electronic resources, available in informational networks in a correct way. In this paper we present the results obtained from evidences on the contrast existing between the level of use of technologies (videogames, social networks...) and the level of informational literacy shown by students. The data were gathered from a sample of more than 1000 Secondary Education students who are around 15 years old. The article also contains bibliographical notes.
