This article describes the application of Problem-Based Learning (PBL) methodology in the context of a student congress, arguing that such new approaches to learning are best-suited to the goals of the Bologna Process. The Congress in question enabled Spanish graduate students in Psychology, many of them mid-career professionals, to increase their learning motivation, delve deeper into the learning experience, and further apply their learning and research. By taking an interdisciplinary approach, all the teachers concerned were able to coordinate their involvement. Feedback received from students and professors confirms that the Congress promoted new strategies and skills including self-directed learning.
