Exploring the Complementary Features of Audio and Text Notes for Video-based Learning in Mobile Settings

BSTRACT In this paper, we compared audio and text note-taking behaviors for video-based learning in various mobile settings. We designed and implemented a note-taking tool and conducted a task-based study to examine how users took audio and text notes differently. Our results show that participants’ audio notes were significantly longer than text notes; longer audio notes were taken to capture unfamiliar video content and participants’ emotions. However, audio notes also raised several privacy concerns. Text notes allowed participants to revise for better accuracy and deeper reflection. Our findings of the complementary features of audio and text notes for video-based learning shed light on designing future note-taking tools that can be used to facilitate learning in varied mobile settings.
