This study aims to analyze a project-based learning (PBL) case utilizing ChatGPT and explore its potential as an instructional support tool. To this end, a PBL course integrating ChatGPT was designed and implemented in the general education course titled ‘Self-Directed Learning Strategies for University Students’ at a university in Seoul during the first semester of 2024. Throughout the course, students used ChatGPT to select presentation topics, conduct research, draft scripts, and deliver their final presentations. To evaluate the effectiveness of ChatGPT integration, a survey was conducted and peer evaluations of project outcomes were analyzed. The findings indicate that students benefited from ChatGPT in various aspects, including organizing presentation content, gathering information, drafting scripts, refining arguments, and generating ideas. Additionally, peer evaluations revealed high ratings for the completeness and coherence of the presentations. These results suggest that ChatGPT can serve as an effective instructional aid by supporting students in the processes of information retrieval and presentation development. This study highlights the potential of ChatGPT to enhance the effectiveness of PBL and offers foundational insights for the design and implementation of AI-assisted educational models.
