Urban Burnik, Janez Zaletelj, Andrej Košir: Video-based learners’ observed attention estimates for lecture learning gain evaluation
This paper suggests an objective and non-intrusive evaluation of learners’ attention against learning outcomes by introducing an observed attention estimate (OAE). The procedure uses human annotations based on visual cues with a supporting video recording/playback system and a web-based annotation system. This proposed procedure enables us to estimate the attention level of individual learners as observed by human annotators for given time intervals associated with specific concepts covered by the lecture.
