Asynchronous Lectures, View-Speed Effect
Ahmad Mohammadpanah, Nima Atabaki · Literacy Information and Computer Education Journal · 2021
A study on the effect of speed-watching of recorded lectures in a second, third-, and fourth-year Mechanical Engineering undergraduate courses and one Graduate level course showed that the view speed (i.e.watching lectures with 1.5 or 2 times faster than normal speed) has no significant effect on the average grade performance.While the data might suggest that the supposed benefits of being able to speed up a lecture (preserving a lecture content while decreasing the amount of time spending on it) does not have any significant effect on a student's understanding of the Engineering topics content, there might be some disadvantages in speedwatching.Through, a post survey of the same sample groups, majority (82%) of the speed watcher reported that they feel a bit impatient when they couldn't "speed up" a live conversation.Some reported the feeling of frustration or a lack of attention when they have to attend a live lecture (real-time speed) or inperson lectures.
