We present preliminary results of the effect of Expo-Based Learning (EBL) applied to a course on information visualization. We define EBL as project-based learning (PBL) augmented with constructively-aligned large public demos [RTP14]. In this paper, we analyze the results of challenging and grading enrolled students to compete and present their projects publicly at an open student competition organized by a second university. We surveyed the students at the end of the course before the competition started and the end of the competition. We present the result of the impact of the student competition as it relates to the intended learning outcomes from the perspective of the students.
