Data Comics for Education: Evaluating Effectiveness, Benefits, and the Ethics of AI-Assisted Creation
For educators and students, this study provides empirical evidence that data comics can enhance visualization literacy, though the use of GenAI introduces ethical issues that need addressing.
Data comics, created with GenAI assistance, improved university students' performance in information retrieval and comprehension tasks compared to conventional visualizations, with higher engagement and ease of understanding, but raised ethical concerns about misinformation and ownership.
In today's data-driven world, students often struggle with interpreting visualisations due to limited visualisation literacy. Data comics have emerged as a promising medium to enhance engagement and understanding, but their educational value has seen little empirical examination, partly due to the effort required to create them. Recent advances in Generative AI (GenAI) offer a scalable solution to this challenge. We conducted a within-subjects study with 60 university students, comparing conventional visualisations with data comics, created with assistance from GenAI tools, across information retrieval and comprehension tasks. Students consistently performed better with data comics, particularly in insight comprehension tasks, independent of prior visualisation literacy. Students also commented data comics as more engaging and easier to understand, though concerns were raised about GenAI-driven misinformation and ownership. Our findings highlight the potential of data comics as a potentially effective tool for data communication in education, while underscoring the need to address ethical concerns related to AI-assisted creation.
