This paper investigates the intersection of media and design literacies in learners becoming more competent in developing complex ideas within a history classroom. Drawing from multiliteracies, design literacy, and media literacy, this paper conceptualizes media design rhetoric as a process. It utilizes a virtual exhibition as a facilitator to deepen the understanding of propaganda. We accumulate qualitative data from artifacts created by 10th and 11th graders (age range: 15-17) in a history classroom within a suburban high school in Western Canada, with written reflections on their artifacts. Artifact analysis is followed by thematic and subject analysis in NVivo 12. Results show that media design rhetoric supports learners in deepening their understanding of propaganda, critically reading media, and creatively communicating messages. Results suggest that virtual exhibitions can be pivotal in creating new artifacts with complex but interest-driven topics. This research introduces media design rhetoric as a bridging concept (between multiliteracies, design literacy, and media literacy) and situates virtual exhibitions as a facilitator for developing complex ideas. This research highlights the significance of critical thinking and creativity in the media design rhetoric, as students critically engaged with historical content and creatively adapted it to modern contexts.
