摘要：Keeping learners engaged in viewing online video lectures is a challenge, which is consideredharder as the length of the video is longer. Although it is a known obstacle, in practice, manyvideos are lengthy and do not contain interactive elements. This study takes an attentioneconomy perspective, and examines if interactivity may enable effective use of longer onlinevideo lectures. Google Analytics data was used to measure average online video lecture viewingcompletion percentage for two ‘long’ and ‘short’ video lecture groups, before and after theaddition of interactive components. Preliminary results show that addition of interactivitysignificantly improved completion percentage as well as average viewing time for both ‘long’and ‘short’ video lecture groups by more than 20%. Furthermore, the average viewing time ofthe ‘long’ group grew to over 10 minutes. The contributions of this study are twofold: itdemonstrates the potential of learning analytics to identify ways to improve learning processes,and it provides empirical support for the potential of adding interactive elements to the videos toexpand the attention span of learners.
