We present a case study analyzing and discussing the effects of introducing the requirement of public outreach of original student work into the project-based learning of Advanced Graphics and Interaction (AGI) at KTH Royal Institute of Technology. We propose Expo-Based Learning as Project-Based Learning augmented with the constructively aligned goal of achieving public outreach beyond the course. We promote this outreach through three challenges: 1) large public presentations; 2) multidisciplinary collaboration; and 3) professional portfolio building. We demonstrate that the introduction of these challenges, especially the public presentations, had lasting positive impact in the intended technical learning outcomes of AGI with the added benefit of learning team work, presentation skills, timeliness, accountability, self-motivation, technical expertise, and professionalism.
