The Reel Deal: Designing and Evaluating LLM-Generated Short-Form Educational Videos

 The paper “The Reel Deal: Designing and Evaluating LLM-Generated Short-Form Educational Videos” presents ReelsEd, a web-based system that uses large language models (LLMs) to automatically create short-form educational videos (reels) from longer lecture content while preserving instructor-authored material, with the aim of supporting microlearning. The authors conducted a between-subjects study with 62 university students to compare the effectiveness of AI-generated short-form videos against traditional long-form lecture videos. The results showed that learners engaging with ReelsEd’s reels demonstrated higher quiz performance, greater engagement and improved task efficiency without any increase in cognitive load. Participants also reported high trust in the system and valued its clarity, ease of navigation and usefulness. The findings highlight promising opportunities for integrating generative AI into educational tools that enhance usability and learner experiences.  Read it here.
