Abstract. Problem Based Learning (PBL) is an instructional method in which the base for learning is a real-world problem. A typical PBL setting is comprised of students working together on an authentic problem, using simple tools such as whiteboards and stationery. Online tools and multimedia technologies have also been used to support PBL activities. There is however no empirical work on the blended use of both physical and digital tools. This paper presents a case study in which we employed PBL pedagogy for the teaching of a postgraduate course in Human Computer Interaction (HCI). The activities were situated in a multimodal information space, rich in digital and physical elements including personal computers, projectors with downwards projection, tablets, iPods, digital pen readers, stationery and a Facebook group for each team. We administrated questionnaires assessing students' motivational beliefs and overall satisfaction with the learning experience. Our results show that students' overall satisfaction was highly rated, while the information space contributed to students' engagement and collaboration.

IntroductionA common barrier in acquiring knowledge presented in class is that students are often disengaged from active collaboration, interaction and reflection. Problem based learning (PBL) is a didactic approach in which the base of learning is the need to solve a real-world problem [1] and providing context-rich situations [2]. A typical PBL setting is comprised by students working together on the problem, using simple stationery. With the advancement of the technology new ideas were brought forefront. Online tools such as forums and blogs, as well as multimedia enriched settings, including games, have been used to support PBL. There is however no empirical support on using both physical and digital tools together in a PBL setting. Specifically, this study attempts to achieve a two-fold purpose by integrating PBL in a technology enhanced environment: first, to explore its possibilities and constraints for teaching HCI; and second, to explore how this space promotes learners' collaboration and engagement.
