This paper regards a validation study aiming to investigate secondary school pupils’ internet attitudes. An 18-item questionnaire was administered to 260 adolescents (12–15 years old) of an experimental school, in Greece. Four factors were extracted: “affection”, “perceived usefulness”, “perceived control” and “behaviour”. The factorial structure of the questionnaire was revealed. The majority of the pupils expressed strong perceptions towards the usefulness of the internet. Over 90% of the adolescents believe that the internet can allow them to do more interesting and imaginative work and that it helps them acquire relevant information. Gender and age were not significantly correlated to the factors. The frequency of internet use had positive correlations with the factor “Behaviour”. “Perceived control” was statistically significant correlated with each of the factors “Affection” and “Perceived usefulness”. The findings are discussed within the context of the safe introduction of digital tools ecosystems of this experimental school in Greece.
