The forms of citizen participation have been reconfigured in recent years. The presence of social networks and digital media in general have favored multiple modes of access to information, expression of ideas and social participation. A necessary reflection to think about a sustainable future requires an assessment of communicative practices in digital media and the challenges in citizen education that globalization entails. This research focused on the analysis of citizen participation practices of university students in digital media and its implications for global citizenship. A mixed investigation with a quantitative-qualitative sequence was proposed. In the first phase, a cross-sectional descriptive study was developed with 740 students from a Colombian university, to whom an electronic questionnaire was applied. In the second qualitative phase, discussion groups were held with 42 students, with the purpose of discussing the findings of the questionnaire from the perspective of the participants. It was found that the practices conducted by the students focus mostly on basic and intermediate levels of citizenship represented in the consultation of online information and expression of the ideological positions in social networks, with high limitations towards higher levels of citizenship referred to concrete actions to impact reality. It is evident that this difficulty in contributing to social changes in the world is due to the lack of education for critical global citizenship. Therefore, critical literacy for the use of digital media is proposed as a citizen educational strategy, considering that it contributes to the construction of a more hopeful vision of the future.
