From a use case concerning a master level course on pedagogical video games, this article describes how Project-Based Learning uses Internet-based services. Initially, Information services have been mostly used to facilitate communication between the students and the teacher, and to provide support in the project management. More recently, Internet has more deeply changed the philosophy of PBL, towards an increased integration into the real world. An innovative approach has emerged, in which products delivered by the students are both disseminated and reused for the course itself, for future classes.
