lecture video curation

Lecture-video curation grounded AI help in course material, but the pilot measured engagement rather than learning

Tang, Vassar and Renzella tested an alternative to open-ended AI answers: use LLMs to retrieve short, educator-delivered lecture clips for novice programming questions. Proprietary models produced relevant and sufficient selections across five benchmark queries, and a 903-student pilot showed repeat use and positive voluntary ratings. However, low overlap with one lecturer, LLM-only quality judgments and no learning-outcome measure mean the study demonstrates retrieval feasibility and engagement, not safer or better learning.
