CHI 2026 Workshop on Understanding and Engaging Critical Resistance to AI in Education

Kim, Baek and Kwak present PedaCo, an AI-video workflow that lets educators revise scripts against multimedia-learning principles before synthesis and then checks the rendered video with automated pedagogical metrics. Twenty-three educators rated reviewed videos higher than baselines, while a 14-video comparison improved coherence and temporal alignment. The workshop study did not measure student learning or long-term teacher workload.
