The aim of this article is to present evaluations by university students, who participated as volunteers in centres established as Learning Communities, on their experience in Interactive Groups. In order to collect the information, we asked the participants to hand in a report containing their evaluations. A qualitative methodology based on content analysis was used to examine these reports. The results were grouped into the following five blocks: what use volunteering in an interactive group has been to them, how they felt during the collaboration, positive aspects of the experience they wished to highlight, the negative aspects of it, and, finally, their proposals for improvement. We end this article by pointing out that the positive aspects far outnumber the negative aspects and also far exceed their initial expectations on both personal and professional levels. Furthermore, the results confirm the practical part of the seven principles of dialogic learning on which this educational action model is based.
