This research paper identifies and analyses the incorporation of the internet into primary and secondary education in Catalonia and its relationship with the organisation, culture and educational practices prevailing in educational institutions. It is based on a survey using questionnaires for a representative sample of all of the primary and secondary educational centres in Catalonia. It is a study that, from the prospective of the directors, the teaching staff and students, tries to understand the level of internet use in the different areas of education- al institutions and to what ends is it used. The study also analyses what type of presence the internet has in the changes taking place in schools and in what way it contributes to the appearance of a new educational culture; one that is adapted to the needs that are starting to form in the information society.
