Our study focuses on a Post-graduation Program at Autónoma University, Portugal, whose regime has gone from face-to-face (f2) to blended- and e-learning. Based on semi-structured interviews, this exploratory study aims to analyse the perceived satisfaction of students attending the program in the different regimes. Considering the interviews made thus far, we have realized that most prefer f2f, though previous experience attending online courses seems to influence students to a more positive assessment of the e-learning regime. Students consider most relevant for their learning process the methodology used - collaborative learning – and the pedagogical relation fostered by the recurring to social networks in addition to the Virtual Learning Systems used. We aim to introduce improvements to the program itself, as well as assess the most important aspects and tools students perceive as contributing to a successful learning process.
