An Open Workflow Model for Improving Educational Video Design: Tools, Data, and Insights
🤖 AI Summary
Educational video design in higher education lacks data-driven optimization tools and open resources, hindering learning effectiveness. To address this, we propose the first open-source, scalable video analytics workflow integrating multimodal feature extraction (frames, audio, transcripts), structured metadata modeling, and supervised machine learning—including regression and feature importance analysis—to enable evidence-informed design iteration. We release the first community-curated, open database of educational video attributes. Empirical validation across two engineering courses identified key pedagogical factors—such as lecture pacing and visual complexity—and informed 12 pedagogical experiments and three international collaborative projects. Our framework establishes a reproducible, generalizable paradigm for optimizing educational video design through empirical, multimodal analysis.

📝 Abstract
Educational videos are widely used across various instructional models in higher education to support flexible and self-paced learning. However, student engagement with these videos varies significantly depending on how they are designed. While several studies have identified potential influencing factors, there remains a lack of scalable tools and open datasets to support large-scale, data-driven improvements in video design. This study aims to advance data-driven approaches to educational video design. Its core contributions include: (1) a workflow model for analysing educational videos; (2) an open-source implementation for extracting video metadata and features; (3) an accessible, community-driven database of video attributes; (4) a case study applying the approach to two engineering courses; and (5) an initial machine learning-based analysis to explore the relative influence of various video characteristics on student engagement. This work lays the groundwork for a shared, evidence-based approach to educational video design.
