This study analyses students’ perceptions of how the collaborative construction of a project online facilitates the acquisition of digital competences. The authors (María Pérez-Mateo, Marc Romero and Teresa Romeu) examine the methodological approach, within the context of the Universitat Oberta de Catalunya (Open University of Catalonia, UOC), of the subject: ICT Competences. This subject is conducted fully online at the UOC, and learners are required to engage in a collaborative project organized in 4 phases: Starting, Structuring, Developing, Concluding. Based on an evaluation research approach, quantitative and qualitative data from a survey have been triangulated. The conclusions reinforce the importance of Computer Supported Collaborative Learning (CSCL) processes, the need to put forward pedagogical proposals for the acquisition of both digital and collaborative competences and the relevant role of the teacher in this process.
