The Harvard course catalog is characterized by constant change. Changing course content and historical events, such as social movements, influence teaching and learning. This research project was a collaboration with the Metalab. Together with Kim Albrecht, who was responsible for stories and visualization we developed the research project Curricle Lens which enables users to explore historical events from Harvard's course catalogue. The data can be explored through four extensive storylines. A scroll-based storytelling module immerses into the complex course structures which unfold over time and provide additional context through pointed essays. Responsive cues in the visualization the user’s information experience and highlight important data points in the visualization. The data is from Harvard's course catalog from 1990 to 2020.
